Dear heat pump experts and experienced home builders,
I would like to be able to estimate which heat pump capacity we really need.
Our project:
2 full floors
No basement
148 sqm
KFW55
A 6kW air-to-water heat pump is suggested in our energy demand calculation.
However, the heating load calculation shows an 8kW air-to-air heat pump in the plan.
Both calculations are rather standard, since it is a developer.
Which information in both documents should I pay attention to?
8kW seems a lot to me, but that is just a gut feeling I developed by reading here in the forum.
The underfloor heating is already installed, also standard, the screed has been resting for 4 weeks and is waiting to be heated up.
Alone, no heat pump there.
The developer would credit us €15,000 if we take care of the pump and installation ourselves.
All these questions overwhelm us.
Is that even possible? Can we use a different model, company?
Is it worth it, is €15,000 okay?
Are 6kW enough?.....
We need ammunition to be able to stand our ground against the developer.
Help!
Thank you!
