1. What is a Heat Pump?

A heat pump is a heating system that captures calories from the environment (air, water, or ground) and transfers them inside your home. It works like a reverse refrigerator.

The COP Principle (Coefficient of Performance)

COP measures heat pump efficiency: for every 1 kWh of electricity consumed, the heat pump produces 3 to 5 kWh of heat.

COP 4

= 1 kWh electricity → 4 kWh heat

2. Different Types of Heat Pumps

Air-to-Air Heat Pump (Reversible AC)

Captures calories from outdoor air and distributes them via indoor units (splits).

  • Simple and quick installation
  • Heating AND cooling
  • No hot water production
  • Not eligible for MaPrimeRénov'

Air-to-Water Heat Pump

Captures calories from air and transfers them to a water circuit (radiators or underfloor heating).

  • Compatible with existing radiators
  • Produces hot water
  • Eligible for subsidies
  • Outdoor unit can be noisy

Geothermal Heat Pump

Draws calories from the ground or groundwater via buried collectors.

  • Consistent performance year-round
  • No visible outdoor unit
  • Maximum subsidies
  • Major works required (drilling/earthwork)

3. Advantages and Disadvantages

✓ Advantages

  • • 50-70% savings on heating
  • • Renewable and eco-friendly energy
  • • Optimal thermal comfort
  • • Significant financial subsidies
  • • 15-20 year lifespan
  • • Property value enhancement
  • • Cooling possible (some models)

✗ Disadvantages

  • • High initial investment
  • • Outdoor unit can be noisy
  • • Reduced efficiency in extreme cold
  • • Requires good insulation
  • • Mandatory annual maintenance
  • • RGE professional installation required

4. Prices and Installation Costs

Heat Pump TypeEquipment PricePrice with InstallationAverage COP
Air-to-Air€3,000 - €6,000€5,000 - €10,0003.5 - 4
Air-to-Water€8,000 - €15,000€12,000 - €20,0003 - 4.5
Geothermal€15,000 - €25,000€25,000 - €45,0004 - 5

Savings Example (120 m² house, air-to-water heat pump)

  • Old oil boiler: €2,500/year
  • With air-to-water heat pump: €900/year
  • Annual savings: ~€1,600/year
  • Net investment (after subsidies): ~€8,000
  • Payback period: ~5 years

5. Financial Subsidies 2026

MaPrimeRénov'

Based on your income and heat pump type:

  • • Air-to-Water: €3,000 to €5,000
  • • Geothermal: €6,000 to €11,000
  • Air-to-Air not eligible
Energy Savings Certificates (CEE)

Premium from energy suppliers: €2,000 to €4,000 depending on model and climate zone.

Reduced VAT at 5.5%

On equipment and labor for properties over 2 years old (instead of 20%).

Zero-Interest Eco-Loan

Up to €50,000 over 20 years with no interest to finance the work.

Important: Subsidies can be combined! A modest-income household can finance up to 90% of a heat pump cost.

6. How to Choose?

1. Assess Your Needs

  • • Area to heat and insulation level
  • • Hot water needs
  • • Climate zone (H1, H2, H3)

2. Check Compatibility

  • • Existing radiators (high or low temperature)
  • • Space for outdoor unit
  • • Space for geothermal collectors (if applicable)

3. Compare Quotes

  • • Get at least 3 quotes
  • • Verify installer is RGE certified
  • • Compare SCOP (seasonal performance)

Tip: Choose a heat pump with SCOP above 4 to maximize savings. SCOP (Seasonal COP) measures performance over the entire heating season.

7. Frequently Asked Questions

How much does a heat pump cost in France?

Prices vary by type: air-to-air from €5,000 to €10,000, air-to-water from €12,000 to €20,000, geothermal from €25,000 to €45,000 (with installation). Subsidies can significantly reduce these amounts.

What subsidies are available for heat pumps in France in 2026?

MaPrimeRénov' offers up to €5,000 for air-to-water heat pumps and up to €11,000 for geothermal. Energy Savings Certificates (CEE) can add €2,000 to €4,000. VAT is reduced to 5.5%.

Does a heat pump work in very cold weather?

Modern heat pumps work down to -15°C or even -25°C. Their efficiency decreases with cold, but they remain effective. Backup heating may be needed in very cold regions.

How much can you save with a heat pump?

A heat pump can save 50-70% on heating bills compared to conventional electric heating, and 30-50% compared to gas or oil heating.
