Owning a swimming pool is a real pleasure, but to truly enjoy it, heating is often essential. Among the available solutions, the swimming pool heat pump is one of the most popular options, as it combines high performance with excellent energy efficiency.
But what is the real cost of a pool heat pump? And is it a profitable long-term investment?

On average, a pool heat pump (PHP) costs between €2,500 and €6,500 to purchase, depending on the model (size and output), the technology used, and the intended usage. To this initial investment must be added annual electricity consumption, which varies according to the pool type and size, geographic location, and swimming habits.

With a COP between 4 and 6 and a highly efficient SCOP, the heat pump is now the most cost-effective, reliable, and efficient solution for heating a swimming pool—whatever the weather conditions.

Under normal conditions of use, heating a 40 to 50 m³ pool often costs less than €1 per day over the swimming season.

Pool heating with a heat pump: key factors to consider

The total cost of heating a swimming pool with a heat pump is made up of two main components:

• Purchase price of the heat pump: from €2,500 to €6,500 incl. VAT, depending on output, technology, and model.
• Annual operating cost: generally 4 to 6 times lower than an electric heater, thanks to outstanding energy efficiency.

What determines the price of a swimming pool heat pump?

There is no “standard” budget for a pool heat pump. The final cost directly depends on several key parameters:

• Pool volume (m³)
• Geographic location (average temperature, wind exposure, sunshine)
• Usage period (summer only or extended shoulder seasons)
• Target water temperature (25°C, 27°C, or higher)
• Presence of a thermal cover (bubble cover, automatic cover, etc.)
• Heat pump technology (standard or Full Inverter)

How much electricity does a pool heat pump actually use?

A heat pump consumes very little electricity because it extracts calories from the ambient air.

• 1 kWh of electricity consumed = 4 to 6 kWh of heat produced
• Key factors influencing consumption:
  • Outdoor air temperature
  • Pool insulation
  • Smart regulation and control systems

Real-life example

For a 45 m³ swimming pool, heated from mid-May to mid-September, with a target water temperature of 27°C:

• Estimated annual energy cost: approx. €250 incl. VAT
• Calculation based on an average electricity tariff and standard climatic conditions

How to reduce the cost of pool heating

High-impact, immediately actionable measures:

• Use a thermal pool cover (up to 60% energy savings)
• Properly size the heat pump (neither over- nor under-sized)
• Choose an Inverter or Full Inverter heat pump for modulated, quiet operation
• Run the heat pump during off-peak electricity hours
• Combine the system with photovoltaic panels to reduce dependence on the power grid

Is heating your pool with a heat pump cost-effective?

Yes. In most cases, a swimming pool heat pump pays for itself within 3 to 5 years.

Why?

• Long service life
• Very low operating costs
• Ability to extend the swimming season
• Increased property value

Mini glossary – Understanding pool heating terminology

• Heat Pump (PHP): Heating system that captures heat from the air to warm pool water.
• Inverter / Full Inverter: Technology that continuously adjusts the heat pump’s output to actual needs.
• COP (Coefficient of Performance): Indicates efficiency; the higher it is, the more efficient the heat pump.
• SCOP: Average performance of the heat pump over an entire season.
• Heat loss: Thermal losses caused by wind, evaporation, or the absence of a pool cover.

Key takeaways

✅ The heat pump is the most economical solution for heating a swimming pool in daily use

✅ Cost mainly depends on proper sizing and real usage conditions

✅ A well-designed installation ensures comfort, low noise levels, and long-term savings
