Warm water all year, without the gas bill.
Pools, spas, jacuzzis and changing-room showers, on plant that keeps its efficiency in the shoulder seasons when everyone else’s falls over.
Pool heating is its own discipline.
Evaporation, not heating, is the cost
An uncovered indoor pool loses most of its heat off the surface. Plant sizing without a cover strategy is guesswork.
Chlorinated water eats exchangers
Stainless will not survive it. Titanium plus correct water chemistry is the only combination that lasts.
Members notice half a degree
A pool that drifts between 26 and 29 °C generates more complaints than a cold one. Stability is the product.
Pool plant, shower plant, and the spa in between.
Most club schemes need two separate circuits — pool water at 28 °C and domestic hot water at 60 °C. Sharing one plant across both is the usual mistake.
Swimming pool heat pump
Titanium exchanger, COP to 6.9, holding setpoint within half a degree through the shoulder season.
Changing-room DHW
Separate plant for showers at 60 °C, sized on the post-class peak rather than the daily total.
Spa & jacuzzi
Compact units for small high-temperature bodies of water with fast reheat between sessions.
- Pool cover strategy, because it changes the plant size materially
- Separate pool and DHW circuits, never shared
- Water chemistry limits written into the handover documents
- Dehumidification coordination for indoor pool halls
- Setpoint scheduling around class timetables and off-season
- Winter operation review before the first cold month
A city club heated three water bodies on two plants.
A 25 m indoor pool, a kids pool and a spa, plus 180 daily showers. Gas was doing all of it at 78% efficiency. Now two plants do it, separately, and the pool holds 28 °C in January.
From first call to handover.
We start with the pool hall, not the plant room.
Survey
Surface areas, cover use, hall humidity, class timetable and shower counts.
Heat-loss model
Evaporation and transmission losses, month by month.
Two-circuit design
Separate pool and DHW selections, with chemistry limits stated.
Commission
Setpoint tuning across a full week of real member use.
