Thanks, everyone,for the replies. I will take your advice, and not try to integ the log burner with the ASHP. Although having our electricity cut off for days at a time has not happened before, with climate change we can expect more extreme weather, and our overhead supply has a line of crack willow and ash trees alongside it.

I am having an ASHP installed in my home next month. I have had an EPC survey done, and everything is OK for getting RHI. In view of the fact that our house was without electricity for 5 days after the storm last week, I would like to have an alternative source of heating for such emergencies. I was thinking of adding a log burner with back boiler, feeding into the same heat store as the ASHP. However, I read somewhere on the Internet that this would not be allowed under the RHI. Is that right? Also, I am concerned about using a heat store with an ASHP. If the hot water runs off a mains pressure coil in the tank, and the tank is only at ASHP temperatures (55 deg or less), will the hot water actually be hot enough? I like my hot baths! Nikki
