VitoEnergy will supply; the heat pump, primary controller, cylinder, underfloor heating (if applicable) and the connection kits (including filter) for the heat pump (if applicable).
The installer will need to supply; pipe, fittings, clips, radiators, 3rd party controls, base materials, heating expansion vessel, diverter and/or 2-port valve, buffer or volumiser.
If you have the BPEC or LCL in heat pump installation and you have registered with us then you can commission and be paid for it, otherwise we will send a commissioning engineer on the last day.
When we complete the heat loss calculation, we take this into consideration. We design the heating system to provide adequate heat down to -2 around Surrey.
We believe it would be a conflict of interest for us to provide an EPC and that it should be independent, for the same reason we do not recommend one. We suggest checking your last EPC on the register and contacting that assessor or checking Google for the highest rated local provider.
It is a common misconception that bigger equals better when it comes to boilers. In fact, an oversized boiler (i.e. excessive capacity) causes unnecessary wear and tear. It can also cause ‘cycling’ – where overheating from excess energy causes the boiler to repeatedly shut down, cool, and start up again, putting stress on the entire system. This was a problem with boilers and had an impact of around 10%, with heat pumps it can be the difference between 200% and 450%! Check out our SCOP explanation blog for more on that here...
