A heat pump for the pool
Purpose-built equipment heats pool water through a dedicated heat exchanger. We check filtration flow, location and electrical supply.

Pool heat pumps in Spain
A pool heat pump matched to your climate, cover and target temperature. Start with the pool dimensions and when you want to swim.
Find my pool heatingCover and heat loss
Water surface area, wind, night temperatures and the cover affect heat loss. The same volume does not mean the same required output.
Your swimming season
Summer evenings, spring and autumn or year-round use need different design conditions. Water temperature and usage matter too.
Compare under the same conditions
Output and COP change with air and water temperature. Peak COP usually occurs at part load and does not coincide with maximum heat output.
Example: Eco Elyo-13 provides up to 13 kW at 26 °C air, 26 °C water and 80% humidity; up to 9 kW at 15 °C air, 26 °C water and 70% humidity.

These are real pool-specific models. Listing one does not confirm that it is correctly sized. Heat losses and installation need checking first.

Pool heating questions
Is pool volume enough to choose a heat pump?
No. Volume helps estimate the energy for the initial warm-up. Selecting output also requires water surface area, outdoor temperature, wind, cover and the intended swimming season.
What should an installation quote include?
It should list the heat pump, bypass, pipes, valves, electrical supply, protection, base and commissioning. Route lengths, access and changes to filtration can affect the cost. We confirm the scope for each pool.
Is heating energy the same as electricity consumption?
No. The initial calculation describes heat needed in the water. Electricity use depends on the actual COP and heat losses during warm-up and temperature maintenance. A cover helps reduce losses, particularly evaporation.
What we check before installation
- Water volume and surface area, depth, indoor or outdoor pool
- Season, target temperature, cover and wind exposure
- Filtration flow, bypass and water-treatment compatibility
- Airflow, clearances, noise and condensate drainage
- Supply phases, available electrical capacity, connections and protection
- Commissioning, settings, winterising and maintenance
What makes up the quote
Heat pump, fittings and bypass, hydraulic route, electrical supply, base, installation and commissioning. The pool cover is considered separately. The questionnaire keeps the inputs and outstanding checks; final output and installed price follow a thermal assessment.
Pool water treatment
Filtration, disinfection and pH control are a separate task. We coordinate heating with the existing treatment system.
