Vaillant aroTHERM heat pump – Manchester

We removed a gas combination boiler and replaced with a 7 KW Vaillant aroTHERM Plus heat pump, a 200-litre cylinder and Vaillant sensoCOMFORT weather compensation controls. 
 
We did not have to replace any existing radiators as our calculation showed that most rooms could be heated with a 45c flow temperature with the existing radiators.
 
The system is designed to operate at 45c when it is -2c outside, to give a 21c temperature in living rooms and 18c in bedrooms. We have been able to reduce this to 40c whilst still keeping the house comfortably warm. As the system is weather compensated, the flow temperature rarely gets to this temperature. 
Energy efficiency
We checked the operation of the system after 6 weeks of operation (in January and February) and had an efficiency of 360% at this time. We expect this to increase over the year to show a greater efficiency in a 12 month window.
 
The system has a lower operating cost than a gas boiler at its current efficiency.
Our client:

The homeowner was keen to install a heat pump as (like us) they believe it is a step in the right direction for tackling climate change. They have also recently installed solar PV panels and battery storage, which allows them to generate their own power – something they couldn’t do with gas heating.

Our 5 star review:

“Liam Knowles and the team did an excellent installation from start to finish. I would highly recommend them to anybody to install an air source heat pump system into their property. We are based in Mancester and they were by far the best team for the job in our area. They cover a lot of the north-west and they are elite Heat Geek installers. Liam and the team went above and beyond to make sure my system was the best that it could be. We did have a slight issue with a small leak and Liam came out the very first thing that day to make sure it was put right immediately. First class service!”

The heating solution
We replaced a gas combination boiler with a Vaillant aroTHERM air source heat pump and Vaillant sensoCOMFORT controls.
Challenges we solved:
The pipework ducts proved to be a challenge where builders had put bends in the pipework, restricting our ability to pull through our planned pipes. We changed our specification to allow it to be installed in the duct, preventing disruption to the newly plastered extension.
