Hello everyone,
Our general contractor has made the following offer. Is this a good price, acceptable, or too expensive? What do you think?
Single-family house, 220 sqm (2,368 sq ft), Saxony
Heating:
Vaillant brine-to-water heat pump VWF88/4 including drilling (3x 70 m (230 ft)) and underfloor heating; complete with installation
= 33,000 EUR (net) (of which 5,000 EUR for heating installation)
Sanitary:
2 bathrooms (2x walk-in showers, 1 bathtub, 2 washbasins, 2 rimless toilets, 1 urinal, towel radiator) — all standard; without bathroom furniture; complete with installation
= 13,000 EUR (net) (of which 4,500 EUR for sanitary installation)
Thanks!

Was there any explanation provided with this recommendation? I understand if shallower drilling is necessary due to the geological conditions. But simply swapping 160 meters (525 feet) of drilling for 210 meters (690 feet), and then adding an extra borehole at almost the same depth???

Especially in the bathroom, I am looking forward to the underfloor heating in winter, as tiles can otherwise be very cold, and the warm towel from the towel radiator will also be quite comfortable.
I'm not talking about wall-mounted radiators, but wall heating—that is basically underfloor heating built into the wall.
In the bathroom, in addition to underfloor heating, we had wall heating installed to ensure it stays warm enough while keeping the supply temperature as low as possible. A towel radiator will hardly get warm enough with a supply temperature of around 30°C (86°F).
This reduces the efficiency of your system because you’ll need to use mixing circuits and unnecessarily raise the supply temperature.
