This renewable tech takes warmth from the air and repurposes it for space heating. But is it the right option for your project? Our expert Q&A goes beyond the basics to answer the in-depth questions you really want to ask
This NIBE F2040 16kW heat pump was fitted by Carbon Legacy

What should you look for to make sure your ASHP is specified correctly?

Robin Adderley: Always appoint an installer who is registered with the Micro Generation Certification Scheme (MCS). This will ensure you get the best advice and gives you access to the Renewable Heat Incentive (RHI).

Phil Birchenough: Your installer should always look at the efficiency of the house and what you need from your heating solution in order to offer you the best solution. As with any system, upgrading insulation in existing homes is important. You should also be confident your engineer fully understands the product they are fitting.

Andrew McLauchlan: The unit should be specifically sized to account for local temperatures, too. It needs to be able to provide all the warmth a property demands, right down to this design temperature. If an ASHP isn’t providing enough heat, then it’s been sized incorrectly.
