Hello everyone,
We were originally planning to install a groundwater heat pump for our new build (Kfw 70). The cost of accessing this heat source would be reasonable due to the high groundwater level of 2.5 m (8 feet). Our neighbors each drilled about 7–8 m (23–26 feet).
However, I learned today from the local district office that the water quality may not be ideal for a water-source heat pump.
Mn: 0.13 mg/l
Fe: 3.2 mg/l
I’m unsure whether we should risk a "conventional" groundwater heat pump here.
Do you know of any alternatives to use groundwater with this poor quality for heating?
Would, for example, energy baskets around 5 m (16 feet) deep be an option? These would reach into the groundwater and could continuously extract energy from the water here as well. According to the district office, such a solution would also be approved.
Other heating methods aside from brine or groundwater heat pumps are basically not an option for us.
Air source heat pump: noise? cost-efficient operation with rising electricity prices?
Gas: uncomfortable feeling, fossil fuel
Pellets: no storage space, as there is no basement (due to the high groundwater level)
Brine deep drilling will not be approved
Brine ground collector: presumably too small an area
Best regards,
FelixDem
