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.
