Is an air-to-water heat pump economical for this house?

Hello,

we are currently considering whether an air-to-water heat pump is economically sensible for a house that meets the Energy Saving Ordinance 2016. The energy demand of the house (145m² living space excl. 22m² hobby room in the basement) was calculated as follows:



At the moment, it is planned to install an air-to-water heat pump from alpha innotec. Ventilation of the living space is done through windows, no ventilation system is planned.

Is it sensible to rely on an air-to-water heat pump here or would other energy sources be more economical?

That strongly depends on the number of loops in the floor. What alternatives would you have? Alpha Innotec is not a good brand, many technical problems and low efficiency.

Here Novelan (identical to Alpha innotec), good efficiency, no technical problems.... But the question of the design of the underfloor heating is crucial. It must fit a heat pump.

Is the house standing or is it still being built?

: More loops => Better?
: To what extent does the underfloor heating need to fit?
: The shell is almost finished.

Maximum supply temperature in the planned design. Possible flow rate (minimum volume flow of the heat pump must be delivered).
