Being a bit slow on the uptake, I've just twigged the difference between the FiT and the RHI  Grin

Having now spoken to 3x Renewable installers, the consensus seems to be a combination ASHP and Solar PV.

Can one claim two separate RHIs for each renewable element? - or does one have to pick one or the other?

You can have both - but the system must be designed in such a way that the solar cannot provide any space heating, i.e. a common thermal store cannot be used, it must feed a hot water tank used only to provide hot water. The RHI allows only a single space heating system per property. Air to air HPs are not eligible.

Make sure you get an EPC done as a first step before committing to anything else.

i wonder what the definition of a dwelling is.  Does it include everything in the curtilage eg greenhouse and swimming pool.

The RHI on a GSHP is a more substantial payment but it is also a more expensive install and depends on your location viz a zip a ground loop/ bore hole.

Might also be worth thinking about a battery storage install at the same time?



1.28kW on a Lorentz ETATRACK1000 + 1.44kW/ SB3000TL-21 (FIT), 1.28kW/ SB1700 (ROO/FIT).
