Pool Heating Systems
A heated pool is a pool that gets used. We design heating around the lowest running cost for your climate and swim season — usually an inverter heat pump, sometimes combined with solar or a gas heater for fast recovery.
Inverter heat pumps
A heat pump moves heat from the air into the water rather than generating it, returning four to six units of heat for every unit of electricity (COP 4–6). Full-inverter compressors modulate output to hold a steady temperature quietly and efficiently.
- Coefficient of performance up to 6.0 at mild air temperature
- Titanium heat exchanger — safe with salt and chlorinated water
- Quiet DC fan operation, suitable for residential boundaries
- Operating range down to −7°C air for extended seasons
Gas heaters
Where a pool must reach temperature quickly — hotels, intermittent-use pools — a condensing gas heater delivers rapid recovery independent of air temperature, and pairs well with a heat pump for base load.
Solar heating
Solar absorbers use the circulation pump to push water through roof-mounted collectors, adding free heat in the swim season. We size the collector area to 50–80% of the pool surface for a meaningful temperature lift.
Thermal covers
Up to 70% of a pool's heat loss is evaporation from the surface. A thermal cover is the cheapest heating upgrade available and we specify one with every heating project.
| Model | Type | Heat output | COP | Pool volume |
|---|---|---|---|---|
| CW-HP09 | Inverter heat pump | 9 kW | 5.8 | up to 40 m³ |
| CW-HP17 | Inverter heat pump | 17 kW | 5.4 | up to 75 m³ |
| CW-G30 | Condensing gas | 30 kW | — | up to 120 m³ |
