Heat Distribution / Circulation System
This is the technology that actually generates or transfers heat to the water. Common options include:
- Air-source heat pumps
- Gas or oil boilers
- Electric heaters

Heat Distribution / Circulation System
To heat the pool effectively, water must be drawn from the pool, passed through the heater, and returned at a higher temperature. This includes:
- Pool pump
- Filtration system
- Pipework and control valves
Heat Retention

Heat Retention
Once the water is heated, keeping the heat in the pool is essential for efficiency and cost savings. This is achieved using:
- Pool covers (thermal blankets, automatic covers, etc.)

About Warm Pools
Expert Pool Heating And Ventilation From Warmpools
Indoor Pool Heating System – Diagram Explanation
Below is a simple overview of how a typical indoor swimming pool heating system works:
- Pool Water Intake
Water is drawn from the pool through the skimmer and main drain into the filtration system.
- Filtration Stage
The pool filter removes dirt and debris to ensure clean water enters the heating system.
- Heat Source (Heat Pump / Boiler / Electric Heater)
Filtered water flows through the heater.
- A heat pump for indoor pools extracts energy from the air and transfers it into the water
- A boiler or electric heater directly heats the water
This raises the temperature to your desired setting.
- Return to Pool
Heated water is pumped back into the pool through return inlets, ensuring even temperature distribution throughout.
- Thermal Pool Cover
When the pool is not in use, a thermal cover sits on the water surface to reduce evaporation and retain heat.
- Ventilation & Dehumidification System
Warm, moist air rises from the pool surface and is extracted by a specialist ventilation unit.
Fresh, temperature-controlled air is then circulated back into the room, maintaining comfort and protecting the building structure.
At Warmpools, we provide expert heating and ventilation solutions for indoor swimming pools, delivering complete, professionally managed installations from start to finish. We bring together all the specialist trades required to ensure your system is installed safely, efficiently and to the highest standard.
