conditions, except in water conservation areas. Permission is also often required to
drill the ground probes for closed brine/water systems. Normally, the drilling
company applies for the required approvals.
From the Idea of a Heat Pump to Owning One's Own System
Determine possible heat sources:
Ground probe - Does deep drilling require approval?
Ground collector - Can a large section of the garden be dug up?
Groundwater - Is the house located in a water conservation area?
Air - Final solution if other sources are not available.
Calculate heat requirement and heating capacity.
Can insulation help to reduce the heat requirement?
Can the required temperatures be reduced through underfl oor heating or large
Request quotations for heat pumps and, if necessary, for the drilling.
Tip: Only HFC-free heat pumps are optimal for protecting the climate.
If necessary, have the drilling company obtain approval for drilling.
Determine optimal energy tariff, and, if necessary, plan to have buffer
storage unit.
Tip: Only green energy is optimal for protecting the climate.
Arrange for system to be installed by a qualifi ed company.
