Does my boiler need replacing?

Thinking about a boiler replacement?

What do you rely upon more than anything else in your home? Probably your boiler.

Although we don’t often think of them until trouble strikes, boilers are the unsung heroes of our warmth and comfort at home.

They provide us with heat and hot water all year round, and they’re often so good at their job, we take them for granted.

But unfortunately, boilers don’t last forever.

If you’ve noticed your boiler is struggling to do what it used to do; or is breaking down regularly; or is not working at all, you might be wondering whether you should try to repair what you have, or whether the time has come for a boiler replacement.

If so, you might like our related blog: 6 signs that you need a new boiler.

The Heating People are here to help you find what’s right for you, and your home. Call us today to discuss your options with a boiler replacement.

Signs that you might need a boiler replacement

Here are some of the signs that it might be time to replace your old boiler with a new one:

Sign it’s time for a boiler replacement: Your boiler is in its ‘golden years’

When you’re thinking about replacing your boiler, it’s a good idea to start by considering it’s age.

A new boiler is unlikely to need to be replaced, but what’s considered an ‘old’ boiler?

There isn’t an easy answer to this question, because just like with us, age really is just a number!

There’s a common misconception that when a boiler reaches a certain age, it needs to be replaced. But this isn’t true.

With regular servicing, some reliable old boilers will keep ticking over, without ever giving much of a grumble.

However, others will start to deteriorate, and may start breaking down, and needing more frequent repairs.

So if your boiler is old, and you notice any of the other warning signs listed below, call The Heating People today.

We’ll advise you on whether it’s time to say goodbye to the old, and hello to the new.

Sign it’s time it’s time for a boiler replacement: Your energy bills have crept up without explanation

You might have heard about the energy efficiency ratings of boilers, or of the Boiler Plus regulations ; but you might not understand what it can mean for your household energy bills.

In its simplest terms, a less efficient boiler costs more to run because they use more energy to heat your home.

An A rated boiler has an energy efficiency of 90% or more.

The Boiler Plus regulations mean that new combi boilers are at least 92% efficient.

To put this in perspective, an older G rated boiler has an efficiency of 70% or less which means for every £1 you spend on your heating bill you are wasting 30p on lost energy.

As well as older boilers tending to be less efficient to start with, their efficiency can also deteriorate further with age.

So if you have an old boiler, and ever increasing energy bills, it might be worth discussing whether a new boiler could save you money.

Sign it’s time for a boiler replacement: Replacement parts are hard to find because of the age of your boiler

If your boiler is very old, it might be pricey to repair if it breaks down, because manufacturers often discontinue spares and accessories on older models.

If it’s difficult for your engineer to find the parts, or expensive to replace them, you’ll need to consider how often you’ll have to do this.

A one-off repair might be ok, but if you’re finding that your engineer is regularly having to scour the internet for obsolete parts, it might be more economical to get a new boiler.

Sign it’s time for a boiler replacement: Your heating system isn’t working like it used to

Over time, you might have noticed that your heating system isn’t working like it used to.

If your radiators are taking ages to get hot, or you’re always cold in certain rooms, or you can’t seem to get enough hot water, it’s time to call an engineer to investigate whether it’s time to replace your boiler.

Sign it’s time for a boiler replacement: Your boiler is regularly breaking down

If you’re having to call out an engineer more than once a year to repair your boiler, it’s worth considering whether the sum of repairs and call-outs is greater than the cost of a new boiler.

If you have your boiler serviced regularly, it should be running smoothly all year, so it might be time for a replacement if yours is still struggling.

Sign it’s time for a boiler replacement: Your boiler or radiators are noisy

All heating systems will make some noise, but if you start noticing new or unusual sounds coming from your heating system, you should get it checked.

If you have tapping sounds, your system might benefit from a Powerflush to clear out sludge which builds up over time.

Other sounds, such as humming or banging might indicate a bigger fault. Your engineer will be able to talk to you about whether repairs or replacements are needed in your situation.

Sign it’s time for a boiler replacement: The flame in your boiler has changed from a blue to a yellow colour

The flame in your boiler should be bright blue. If it changes colour, you should contact a Gas Safe engineer immediately.

The Heating People will be able to advise you as to whether a repair is possible, or whether you need to replace.

Sign it’s time for a boiler replacement: Your boiler smells odd when it is on

A hazard sign.If you ever smell sulphur or an eggy odour when you use your boiler, there could be a gas leak.

Immediately turn off the boiler and call the emergency gas line on 0800 111 999.

Then get in touch with a Gas Safe engineer. You should do this if you ever notice an unusual smell coming from your boiler.

Sign it’s time for a boiler replacement: Your boiler is leaking waterYour boiler should never leak! If it does, you need to switch it off and have it checked by a professional.

It could be a broken valve or seal, which might be repairable, or it could be indicative of a bigger problem, where a replacement might be your better option.

Sign it’s time for a boiler replacement: Your boiler is not working at all

If your boiler stops working completely, it doesn’t necessarily mean that you need a brand new one, but it’s definitely worth talking to your engineer about whether repair or replacement is the best option for you.

What will I stand to gain from a boiler replacement?

If you recognise any of the warning signs that your boiler might be on its last legs, you might be wondering what you stand to gain from a replacement.

Here are just some of the advantages to investing in a new boiler:

Benefit of replacing your boiler: A warmer, more comfortable home

If you’ve been feeling chilly lately because your old boiler has been struggling to heat your home, you’ll love the benefits that a modern boiler will bring.

No more waiting for a heating system that takes ages to kick-in, or wearing two jumpers in your lounge!

Benefit of replacing your boiler: More reliable hot water

If baths and showers have been a battle ground lately, because there never seems to be enough hot water, a new boiler might solve this for you.

If your current problem is that you’re having to wait ages for water to heat up, a combi boiler might fix this for you.

Or, if your issue is that your combi isn’t coping with the increased demands of a growing family, switching to a heat-only or system boiler might be your answer.

Whatever the situation, our team at The Heating People can make sure that your upgrade is going to meet your hot water needs.

Benefit of replacing your boiler: Quieter boiler operation

Fed up of your banging or whistling boiler?

If your old boiler was really noisy, you might well notice how much you don’t notice your new one!

Due to improved design, new boilers can be significantly quieter than older ones.

Benefit of replacing your boiler: Space saving

If you currently have a heat-only boiler, and switch to a system boiler, you’ll save space because system boilers only have a hot water cylinder, they don’t need a cold water tank in the loft.

And if you switch to a combi boiler, you’ll save even more space because combis are compact all-in-one units that don’t need any external tanks or cylinders. They often fit in a kitchen cupboard.

So replacing your boiler could mean that you can get your airing cupboard back, which can be particularly beneficial in smaller homes.

Benefit of replacing your boiler: Reduced energy bills

A family putting coins into a piggy bankA major advantage of a boiler replacement, is that it could save you a lot of money on your energy bills.

The Energy Saving Trust estimates that boilers are responsible for 55% of your household energy bills, so upgrading from a G rated to an A rated boiler could save you up to £200 per year!

To find out why the price of gas is on the rise, check out our related blog here.

So it’s definitely worth having an efficient boiler in your home!

Benefit of replacing your boiler: Better for the environment

There’s no doubt that by installing a new, more efficient boiler, you are also helping the environment.

It’s estimated that around 20% of all UK carbon emissions come from home heating.

Modern A-rated boilers are superior to their older, lower rated counterparts because they recycle heat that would be wasted. This means that they can generate more heat from the same amount of fuel.

It’s estimated that by moving to an A-rated boiler, you could save the environment 1,500kg of carbon dioxide per year.

Benefit of replacing your boiler: More control

A woman operating smart heating from her phone.When you replace your boiler, it’s the perfect time to upgrade your heating controls too.

Effective heating controls are a vital part of an efficient central-heating system.

If you’re replacing an old boiler with a much newer one, chances are, your new model will allow you to have much more control over the heat in your home, than in the past.

Clever use of controls can help you minimise energy consumption by ensuring each room is at the right temperature for comfort.

Smart controls allow you to remotely control your heating system, wherever you are in the world.

Benefit of replacing your boiler: Peace of mind

If your old boiler has been keeping you up at night with worry, all of that will end with a new reliable boiler.

You’ll end all the stress about strange noises and constant breakdowns.

No more inconvenience in having to arrange last-minute call-outs and repairs.

A new boiler should work better for longer, and all new boilers with The Heating People come with guarantees of up to 14 years, for your peace of mind.

Benefit of replacing your boiler: Manufacturer’s guarantee

All of the boilers supplied by The Heating people come with a guarantee of up to 14 years.

This means that should your boiler breakdown, all labour and materials required to get the boiler back to working order are covered.

Now how’s that for peace of mind?

Benefit of replacing your boiler: Reduced repair costs

The guarantee on your new model will mean that should anything go wrong, repairs will be paid for. Anything outside of guarantee is likely to cost less than repairs on a very old boiler, where manufacturers have discontinued parts.

Benefit of replacing your boiler: More convenient location

Renovating your home? If so, the location of your current boiler might not be convenient, and a replacement boiler might be in order to get your boiler where you need it to be.

Benefit of replacing your boiler: Make your home more attractive to buyers

Thinking of moving home soon? A new A-rated boiler can make your property more attractive to prospective buyers.

How much will a boiler replacement cost?

The cost of a new boiler depends on the type of boiler you wish to install and the system that you already have. However, the cost is generally around £1800 with The Heating People. 

How long will a boiler replacement take?

The time taken to complete a boiler replacement will vary depending upon what system is already in place (and it’s condition) and what it is being replaced with. Installations typically take between 1-3 days.

Why choosing a Gas Safe engineer is so important

We all know that gas can be dangerous. So its vital that you choose a Gas Safe engineer to ensure your gas work is carried out legally and safely.

Rest assured that engineers at The Heating People are Gas Safe registered for working on gas.

Your safety is of paramount importance to us. So, in today’s blog we want to explain why choosing a qualified engineer is vital.

Not just to keep you and your family safe, but to keep your boiler running smoothly too.

What are the risks of having unsafe gas appliances at home?

If you have any gas appliances in your home; so it’s essential to have them checked once a year by a Gas Safe engineer to keep them safe.

If any of your appliances are improperly fitted; repaired; or maintained; or any of their vents; flues; or chimneys have become blocked, they can pose three main risks to life:

  1. Gas leaks

A gas leak can cause fires or explosions. So, if you think you can smell gas, then you’ll need to call your emergency service provider immediately.

During a gas safety check; a Gas Safe registered engineer will do a visual inspection of pipework; and a tightness test to confirm there aren’t any gas leaks.

  1. Fires and explosions

Safe appliances burn gas in a controlled way. But faulty appliances or pipework can potentially leak gas. If ignited, this causese fires and explosions.

  1. Carbon monoxide poisoning

If any of your gas appliances aren’t burning their fuel as they should; they can produce a highly poisonous gas called carbon monoxide (CO).

Exposure to this gas can lead to death; and it’s especially dangerous because you can’t see, taste or smell it.

Thankfully you can avoid all of these dangers, by making sure that you have a gas safety check once a year by a Gas Safe registered engineer. 

What is Gas Safe?

The Gas Safe Register is the official list of gas businesses, who can work safely and legally on boilers; cookers; fires; and all other gas appliances.

It’s the only official gas registration body of the United Kingdom, the Isle of Man and Guernsey.

It’s a legal requirement that gas engineers are listed on the Gas Safe Register.

The Gas Safe Register issues licenses for engineers to undertake gas work on behalf of a registered business. They must evidence competency through valid and current qualifications.

Is Gas Safe different to CORGI?

‘CORGI’ no longer exists. Because it was replaced by The Gas Safe Register on the 1st of April 2010. So, The Gas Safe Register is the only gas registration body in Great Britain and the Isle of Man.

What does the law say about Gas Safe?

Only Gas Safe registered engineers can legally fit, fix, and service gas appliances. This requirement ensures that engineers who are working on gas hold valid and current qualifications.

Rest assured, our engineers are Gas Safe registered.

What does the Gas Safe Register do?

The Health and Safety Authority for each region operates the Gas Safe Register.

The Gas Safe Register can’t recommend a particular Gas Safe registered engineer over another. So what exactly is their role?

Here’s a handy guide to what the Gas Safe Register does, and doesn’t do:

What the Gas Safe Register does:

  • Operates the official UK list of gas businesses and qualified gas engineers; so that only qualified engineers are licensed to legally work on gas.
  • Inspects businesses on the Gas Safe Register so that they are applying gas competence.
  • Investigates gas safety complaints.
  • Applies sanctions for unsafe work or breaches of rules of registration.
  • Investigates reports of illegal gas work and reports their findings to the Health and Safety Executive (HSE).
  • Undertakes consumer campaigns to raise the awareness of gas safety issues such as carbon monoxide (CO); and the dangers of using illegal engineers not on the Gas Safe Register.
  • Provides a facility for registered businesses to notify that the installations of heat producing gas appliances; and the hot water and heating systems they serve; are compliant with the Building Regulations in England and in Wales.

The Gas Safe Register do not:

  • Have the authority or ability to recommend a registered engineer. 
  • Employ the Gas Safe registered businesses or engineers.
  • Investigates or deal with matters such as: financial, contractual or commercial disputes.

So in other words, you can check whether your engineer is Gas Safe via the Gas Safe register.

This gives you the peace of mind that they will be operating legally and safely.

Why is it important to use a Gas Safe engineer?

Choosing a Gas Safe engineer to work on your gas appliances is a legal requirement. It’s vital for your safety in avoiding risk of fire, explosion and carbon monoxide poisoning.

Regardless of what type of gas appliance your engineer is fixing; be it a boiler; oven or gas fire; it’s crucial that your engineer is technically competent and follows all of the relevant health and safety regulations.

Gas Safe engineers demonstrate competence through their qualifications and are therefore licensed to undertake gas work.

In addition to their qualifications, they receive ongoing support to ensure their work meets current regulations; and is technically of a high standard.

Gas Safe engineers perform gas work safely, and prevent harm from occurring.

Gas Safe engineers assess the physical condition of your gas appliances, installation pipework, air vents and any flues for deterioration.

They carry out performance tests to ensure your appliances are operating safely and efficiently. They take any necessary remedial action, alerting you to any issues.

How to check whether an engineer is Gas Safe registered

Not all engineers are qualified to do all types of gas work. So you should check whether they’re Gas Safe registered, before you employ them.

You can inspect an engineer’s official ID card before any work is carried out.

The ID contains important information about the engineer. It says who they are; states their licence number; the business they work for; and the work they are qualified to carry out.

You can check the back of the ID card to see the qualifications that your engineer holds.

They divide qualifications into domestic and non-domestic categories. And list the name of the work they are qualified to undertake along with the expiry date.

You should check that your engineer has the relevant qualification to carry out the work required. For example, if they have come to service your boiler it should list ‘Gas Boiler’.

Also check that the qualification has not expired. 

How to check with the Gas Safe Register

You can check if a business is currently Gas Safe registered by entering their business registration number; or their trading name at: https://www.gassaferegister.co.uk/find-an-engineer/.

If you don’t know their registration number; or business name; or it is not returned as a search result; you can send an email to the Gas Safe Register at register@gassaferegister.co.uk. They will be able to confirm the businesses registration status for you.

Unfortunately, the Gas Safe Register cant recommend a Gas Safe engineer over another one. But they can tell you whether a business is registered to work on gas, or not.

What happens during a gas safety check?

Only Gas Safe engineers can carry out gas safety checks. A Gas Safe engineer will test your gas appliances to make sure they’re safe.

At The Heating People, our engineers will check that your appliances are:

  • Properly set and adjusted so the gas burns correctly;
  • Are suitable for the room it’s located in;
  • Is physically stable, securely fitted and properly connected to the gas pipework.

We will also check that:

  • There’s an adequate and permanent air supply that’s suitable for the appliance installed;
  • All safety devices are functioning properly;
  • Any flues, chimneys and air vents are operating correctly.

We can extend to a full gas installation safety check, in which we will:

  • Check the installation is in good condition by visually inspecting the pipework as far as reasonably practicable;
  • Test the gas pipework to make sure there are no leaks.

Do Gas Safe engineers provide any particular documentation following completion of gas work?

When an engineer undertakes gas work at your property; it’s helpful to know what documentation you can expect to receive from them.

The documentation an engineer leaves after having fitted; serviced; or safety checked an appliance; depends upon the purpose and type of work involved.

Building Regulations Compliance Certificate

If a Gas Safe registered engineer installs a heat producing gas appliance in your property; you will receive a Building Regulations Compliance Certificate.

This informs the Local Authority of the new appliance. And you should receive it in the post within 28 days of a new appliance being installed.

Landlord Gas Safety Record

The law requires all gas engineers to be on the Gas Safe Register. But they don’t have to provide a Gas Safety Record after they visit you, unless you’re a landlord.

The only documentation required by law is a Landlord Gas Safety Record.

This is because landlords have a legal duty to ensure residential properties are safe for their tenants.

Landlords must employ a Gas Safe engineer to perform an annual gas safety check on all gas appliances. The Landlord Gas Safety Record records the results.

Landlords should give a copy of this record to their tenants; so that they know that their appliances meet the appropriate safety standards.

What steps should I take for Gas Safety?

To sum up, here are the key steps that you can take to ensure that your home stays safe:

  • Find a Gas Safe registered engineer that you can trust

Remember that only Gas Safe registered engineers can legally fit, fix, and service gas appliances.

You can find a Gas Safe registered engineer at GasSafeRegister.co.uk (the UK’s official gas safety body) by postcode; by company name; by service and areas of work.

Our engineers are Gas Safe registered; and will be happy to show you their ID cards.

  • Get your engineer to service your boiler (and gas appliances) every year

Remember that you must have all of your gas appliances checked each year to check they are burning gas properly.

Npower says 61% of the UK hasn’t had their boiler serviced in the last year. This is very worrying! It’s vital we take precautions in our home to protect ourselves and our families from the dangers of gas. 

  • If you are a tenant – ask your landlord for a copy of the gas safety record

You’re entitled to a certificate that guarantees the gas fitting has been checked; and meets the national safety standards. Landlords are legally responsible for providing you with a gas safety record.

  • Be aware of the warning signs of unsafe gas appliances

Warning signs include higher levels of condensation in your home; black marks on your gas appliances; yellow or orange flames of the gas cooker (rather than blue).

  • Be aware of the 6 signs of carbon monoxide poisoning

The six warning signs of CO poisoning are:

  1. Headaches;
  2. Dizziness;
  3. Breathlessness;
  4. Nausea;
  5. Collapse;
  6. and loss of consciousness.

You can fit a carbon monoxide alarm, which alerts you to any carbon monoxide leak around your property.

 

Final thoughts…

We hope that you’ve found this blog helpful in understanding why choosing a Gas Safe Registered engineer is sso important.

An annual boiler service gives you the peace of mind that you and your family are safe.

7 Central Heating Myths debunked

There’s nothing like a bit of snow and frost to get people falling into the trap of cranking up their thermostats in an effort to keep warm.

If you’ve done this yourself, don’t worry, you’re not alone. According to a survey by the Energy Saving Trust, 52% of people are guilty of doing this!

Lots of people mistakenly believe that by turning up their thermostat, their homes will get hotter quicker – but this is a central heating myth.

When it comes to heating our homes, there are a surprising number of myths out there.

So today, we’re looking at some of the most common misconceptions, to help you separate heating fact from fiction.

Central heating myth 1 – Turning up your thermostat heats a room quicker

We understand that when it’s freezing outside, it’s tempting to turn up your thermostat.

But this won’t heat your home any quicker, it just wastes energy and money.

This is because thermostats don’t have any control over the speed at which your house heats up. Thermostats just set the maximum temperature that you want your room to be.

So, if you’ve let your home get freezing cold, there’s no point cranking your thermostat up to 28 degrees. Your home will still heat up at the same speed that it would if it was set to 21 degrees.

The result is that you’ll get uncomfortably hot, and have wasted a significant amount of energy by overheating your home.

Government research has shown that turning down your thermostat by just 1 degree can save up to 10% on your heating bills.

So, if you want to be comfortable and save money, resist the temptation to turn your thermostat higher than your comfort level.

Put on an extra jumper on until your room gets to your desired temperature!

Central heating myth 2 – A bigger boiler is better because it will give you more heat

Another common heating myth is that when choosing a boiler, bigger is always better.

And it’s easy to understand why people fall into this trap. Nobody wants to run out of hot water, and it seems reasonable to expect that a bigger boiler will have a more plentiful supply than a smaller one.

But this simply isn’t true, and it’s an expensive and highly inefficient way of choosing a boiler.

A good way to think about this, is to think about the performance of cars.

If you want a reliable car to pop to the shops every day, there’s little point in buying a Ferrari with a five litre engine, that can reach speeds of 200mph.

You’re never going to hit that speed, and it’s going to cost you more to buy initially, and more to run in fuel. The same is true of boilers!

Heat loss calculations determine the size of boiler you need

A calculator next to a thermal image.Instead of choosing a boiler based on a maximum capacity (that it will rarely run at anyway) you need to get a boiler that’s correctly sized.

To do this, you need a heat loss calculation. This will determine the right output for your needs.

Your whole heating system needs to be taken into account. Even where a bigger boiler is pushing out more heat, if your radiators aren’t a good match for it, the amount of heat received will be the same as it would be with a smaller boiler.

Factors such as the boiler’s modulation ratio are more important than its maximum capacity.

Put simply, you won’t benefit from better or improved heat, simply because your boiler is bigger than usual.

Oversized boilers will cycle on and off, wasting energy (and money). Boiler cycling also puts unnecessary pressure on your boiler’s component parts.

To find the correct size boiler for your needs, contact The Heating People today, and one of our heating engineers will carry out a heat loss calculation for you.

Central heating myth 3 – Expensive boilers are always the best boilers

As consumers, we’re often led to believe that the more expensive something is, the better it is. But this isn’t necessarily the case.

In fact, choosing a boiler because of its price, rather than whether it is right for you, is a mistake.

At The Heating People, we’re not tied to any one manufacturer (although we have our favourites!) and we pride ourselves on finding the best boiler for your needs and budget.

We are able to find the most efficient boiler for your needs, which will save you money in the long run.

We also offer guarantees of up to 14 years, which will potentially save you money on any future repairs. It’s important to think about long term costs, as well as the initial cost.

Keeping up with your annual service by a Gas Safe engineer is one way to keep your boiler in great condition for a long time.

Central heating myth 4 – Combi boilers do not give you a very good shower or bath

There are lots of outdated myths about combination or ‘combi’ boilers, based on what used to be true around 15 years ago.

But like many things, combi boilers have come a long way since they were introduced to the UK in the seventies.

And there’s definitely a reason that they’re now the most popular type of boiler in the UK, making up over 80% of all sales.

This has further driven combi boilers to be more efficient and higher performing.

The main perceived disadvantage (or myth) about combi boilers is that they don’t give very good showers or baths. This is a hanjgover from the past, when they did struggle to meet hot water demands.

How do combi boilers work?

To understand why this used to be the case, it’s helpful to think about how combi boilers work, compared to heat-only or ‘regular’ boilers.

Combis are compact all-rounders that provide both the heating and hot water for your home.

Unlike heat-only boilers, combis don’t need a separate cold water storage tank or an external hot water cylinder. Everything it needs is inside the unit.

Combi boilers take their cold water supply directly from the mains. And they don’t store hot water, because they heat water instantaneously, on demand.

Since combis heat water on demand, the flow rate of the water has to be slowed down. This allows enough heat to be transferred, before it comes out of your taps.

Combis used to be slow in delivering hot water because they relied on a mechanical type of operation to heat water.

They also used to be adversely affected by cold weather and hard water. Neither of which is ideal for a boiler in the UK!

But thankfully, technology has moved on. Combi boilers have improved significantly in the last fifteen years.

Combi boilers and Boiler Plus

Diagram showing Boiler Plus.Thanks to the Boiler Plus Regulations, all new combi boilers must be at least 92% efficient.

Combi boilers must also have one of four additional energy saving measures installed.

But the performance of combi boilers is where dramatic improvements have been made.

Advancements in technology mean that combis now use an electrical operation process, rather than a mechanical one.

This means that the old problems with the delay in delivery of hot water is a thing of the past.

With no water tank to heat up, combi boilers can provide an unlimited supply of hot water on demand.

This is ideal in busy homes where showers may be used back to back each morning. It also means no more waiting for water to heat up for your bath. A combi is ready when you are!

Central heating myth 5: Combination boilers are not suitable for larger homes

Another common misconception about combi boilers is that they are not suitable for heating larger homes.

But this isn’t true, even the smallest combi boiler will comfortably heat the vast majority of larger homes.

This assumption about house size and combi boilers stems from the way in which they work.

As explained above, combis provide instant hot water to taps and showers by heating water directly from the mains.

This is different from heat-only and system boilers which store hot water in a cylinder.

Combis deliver strong water pressure to one tap (or shower) at a time. But if multiple outlets are being used at once, the pressure can weaken.

This means that combi boilers are best suited to homes with relatively small hot water demands at any one time.

But this doesn’t mean that a combi cannot heat a larger home.

The real drivers for determining the best type of boiler, is by establishing:

  • the heat load of your property;
  • how many bathrooms you have; and
  • how you use your domestic hot water.

How do you use your hot water?

The number of bathrooms is a better indicator than the overall size of the house.

For instance, if you have a large house with just one bathroom, where the shower will be used consecutively each morning, then a combi may be fine.

But, if you have multiple bathrooms and everyone wants showers at the same time; then a combi won’t be suitable.

In this case a heat-only or system boiler might be your better option.

Some manufacturers also offer storage combi boilers. These boilers have a hot water cylinder within the unit itself. This allows them to meet a higher demand for heating and hot water than a standard combi.

Central heating myth 7 – Painting your radiators makes them more efficient

A mother and child by a radiator.Some people make the mistake of thinking that painting radiators black will make them more effective at transmitting heat. But please don’t do this!

In reality, painting your radiators will have the opposite effect. Paint will stop heat being dispersed as easily, making them less effective.

You should also avoid placing any large furniture in front of your radiators. And don’t hang your washing on them either – invest in a clothes airer instead.

If you’ve noticed cold spots on your radiators, they may need need bleeding. Check out our step-by-step guide on how to do that, here. And if you really want to improve their efficiency, consider installing TRVs.
