This is an estimate based on average 2026 prices. Actual costs may vary. Always request multiple quotes for an exact price.
Cost factors
The total cost usually consists of:
- System and materials: 40-50% of the total
- Labor: 25-35% of the total
- Subfloor and preparation: 15-25% of the total
- Controls and commissioning: 5-10% of the total
These percentages can vary depending on the situation and materials chosen.
Why do prices vary?
- System choice: Water-based or electric determines price and energy use.
- Subfloor build-up: Floor type and thickness affect installation.
- Insulation: Better insulation reduces usage but adds upfront cost.
- Controls: Smart thermostats and zones increase the price.
Subsidies & incentives
There is no direct regional renovation grants available for underfloor heating itself. However, you can benefit from indirect subsidies and tax advantages by smartly combining underfloor heating with other energy-saving measures.
Indirect Subsidy Options
Underfloor heating works optimally at low temperatures, making it the ideal system to combine with a heat pump. This allows you to benefit from:
1. regional renovation grants for heat pump
- Base amount: €1,025
- €225 per kW capacity
- A+++ bonus: €200
- Total for 4 kW heat pump: €2,125 subsidy
2. regional renovation grants for floor insulation
When installing underfloor heating, floor insulation is essential for optimal efficiency:
- Standard: €5.50 per m²
- When combined with other insulation measure: €11.00 per m²
- Biobased bonus: €2.00 per m² extra
Total Package Example
Underfloor heating (100 m²) + heat pump (4 kW) + floor insulation (100 m²):
- Heat pump regional grants: €2,125
- Floor insulation regional grants (combined rate): 100 m² × €11.00 = €1,100
- Total subsidy: €3,225
Payback Period
The combination of underfloor heating with a heat pump and good insulation results in:
- 30-50% lower energy costs compared to gas boiler
- Payback period: 4-8 years (including subsidies)
- Optimal efficiency through low supply temperature (30-40°C)
