Looking at the ducted gas heating / add-on refrigerated cooling in my tender document. I've opted for a Brivis gas ducted heating with add on refrigerated cooling (17.1 kW). Is that enough for a 2 storey house approx 37 squares?
It's current configured into 2 zones, upstairs and downstairs. Upstairs, I have all the bedrooms and an activity area. Downstairs, I have the rest of the living areas such as kitchen, study, lounge, rumpus etc. Is this zoning configuration ok? I guess it sort of make sense as you're either upstairs in the bedroom or downstairs for the rest of the day right?
Is there anything else I need to be aware of?
