ᐅ 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 2016 Energy Saving Regulation. The energy demand for the house (145m² (1560 ft²) of living space excluding 22m² (237 ft²) of hobby room in the basement) was calculated as follows:

The plan is currently to install an air-to-water heat pump from alpha innotec. Ventilation for the living area will be through windows; no mechanical ventilation system is planned.

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

That depends greatly on the number of loops in the underfloor heating. What alternatives do you have in mind? Alpha Innotec is not a good brand, with many technical issues and low efficiency.

Here Novelan (technically identical to Alpha Innotec), good efficiency, no technical issues.... But the key question is the design of the underfloor heating. It must be compatible with a heat pump.

Is the house already built, or is it still under construction?

@Bookstar: More loops => better?
@Daniel-Sp: How much does the underfloor heating need to match?
@T_im_Norden: The shell of the building is almost finished.

Maximum supply temperature in the planned design. Possible flow rate (minimum volume flow required by the heat pump must be provided).
