Heat pump installer Kolham
Kolham falls within the Groningen earthquake zone, meaning sustainability work often coincides with structural strengthening through NCG/IMG programmes. A heat pump is typically included in the overall package.
Why a heat pump in Kolham?
Groningen winters are relatively cold but dry. Air-to-water heat pumps perform excellently here once the home is insulated. For older homes without cavity walls, hybrid is the sensible route.
For homes in Kolham, insulation is the foundation. Only after HR++ glazing, a properly insulated roof and cavity wall insulation does a heat pump reach its full efficiency. For older homes without a renovation history, a hybrid system is often the most cost-effective first step.

Costs and subsidy
Price indication for Groningen: air-to-water €6,000-€11,000, hybrid €3,500-€5,500. A ground-source heat pump (closed-loop borehole) costs €15,000-€22,000 but delivers higher efficiency. Through the ISDE scheme administered by RVO, you receive €1,750-€4,575 subsidy depending on capacity and system type. Apply for ISDE before signing a contract — retroactive applications are not possible.
Installers must meet two legal requirements: valid F-Gas certification and STEK registration. Without these, a technician is not permitted to handle refrigerants. Ask for this explicitly in every quote request.
