Heat pump installer Delft
Delft falls within Zuid-Holland, where the maritime climate brings mild winters and terraced and corner houses are the dominant type in village centres.
Why a heat pump in Delft?
Mild winters (3-4°C average in January) make this area favourable for air-to-water heat pumps. SCOP 3.9-4.4 is achievable for well-insulated homes.
For homes in Delft, 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 Zuid-Holland: air-to-water €7,000-€13,000, hybrid €3,800-€6,500. 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.
