Hello all,
I am currently deciding on a ASHP for a 260sqm new-built home.
Initially the plan was to go with an 11kW Thermia Atec as proposed by the supplier. Now I have seen Thermia has an iTEC version which is a modulating ASHP.
By no means an expert, but what I have read so far is that the modulating heat pumps are superior compared to the non-modulating ones.
Wondering if someone has experience, especially in those 2 Thermia ASHPs? Would you go for the iTec or the Atec?
Next thing would be the size.... presumably 11kW are a bit oversized? It`s a newbuild with tripple glazing, 3 bathrooms and cavity walls (U=0.13). MHRV is installed as well - therefore I am inclined to go with a 9kW version. What do you think?
Cheers,
Tom
