Planning of heating and ventilation technology for KfW 40-Plus single-family house

Does the outdoor unit of the air-to-water heat pump have to be within the building envelope? Or can the outdoor unit also be placed 1m in front of the boundary?

The neighbor would not really be affected, as there is a slight slope of about 1m between the properties.

Hello everyone,

today is the first consultation appointment with the heating engineer who will install the heating and ventilation technology. Is there anything I should point out to him today or ask about?

Thank you

Installation spacing of the underfloor heating max. 10 cm and the length should, I think, be about 80-100m per heating circuit. I learned that from the forum. Oh, there should also be a heat load calculation for each room.

Ask which manufacturers he is familiar with and what he frequently installs, including exact model details, etc.

Room-by-room heating load calculation and delivery of the same.
Specify the heating flow temperature; I would not accept anything above 30 degrees.
Specify the temperature of the individual rooms.
Heating circuits no longer than 100 meters, all approximately the same length.
Do not go below 17x2 pipes.
Address wall heating in bathrooms.
Have it installed under the shower and bathtub.
Try to ensure that he does not make circuits from partial sections with pressing.
Connection of the HKV sufficiently dimensioned.

What reason is there to plan a KfW40+ with a hydronic heating system instead of heating directly with electricity like infrared and only using a heat pump for the hot water?
Whether the fireplace will even be allowed to operate after 2026 is also questionable, since the fuel is fossil like oil.

And then you want to achieve at least 24° in rooms like the bathroom?
