Are heat pumps any good.

I have been considering fitting a ground source heat pump but seem to be getting lots of conflicting advice such as they are problematic plus they are not as efficient in the real world as the manufactures suggest.  Is it worth going down this route especially as I do have mains gas?


Surely they are! I've been also considering whether it's worth the investment. A ground source might become problematic, due to a lower depth of installation. However, try to look at air source heat pumps too. They are a good alternative, in case you are are not sure whether to get a ground source heat pump.


We live in a rural area in the UK and recently installed an 18kW air source heat pump to switch from an oil boiler. So far it's been great.

People have a lot of questions about ASHPs and how they differ so you can read about our system overview here:

Or you can watch an overview of our air source central heating on YouTube:

We hope this casts some light on moving from an oil boiler to ASHP, which is what most people will be considering.


I live in a small, social housing bungalow. Initially a ground-source heating system (Dimplex) was installed that ran successfully for 10 years. It needed fairly regular top-ups of the brine circuit. Then it failed. Dimplex are not good at customer service and a so-called local engineer could not rectify the failure. The housing association then installed air-source heat pumps (Mitsubishi) in all the nine bungalows because all the ground-source pumps had failed. Air-source pumps seem to be more reliable but are not as cheap to run for the householder as ground-source pumps even though I have 10 solar panels on my roof. Manufacturers are prone to telling marketing porkies in promoting their products. In the case of air-source manufacturers: "draws available warmth in from the air." When the air temperature is zero or below, how can there be any warmth in the air? The housing association is now looking in the direction of electric-ceramic radiators.


I also want to install several pumps in my house
