Heat Exchangers for Swimming Pools

Plate heat exchangers are often used in swimming pools and spas to regulate temperature, ensuring that – indoors or outdoors – your pool is heated to the optimal temperature.

With swimming pools, heat exchangers can help heat your pool and regulate the temperature by transferring heat from a heating source, such as solar or geothermal, and redistributing it to a pool. They also act as a barrier to any contaminants or chemical treatment in the pool water.

The pool water is normally heated indirectly using a hot water source to heat the circulating pool water using a plate heat exchanger. The heating source could be geothermal, a heat pump, electricity, or by a boiler that might be used for other duties in the house. The cheapest of these options are solar and geothermal. If you have either of these available, a heat exchanger is bound to improve the efficiency of heating and also will keep the temperature consistent.

With solar heating much more economical than it was in the past, using one of these options (or a bore) means that heating your pool is much more achievable than before. In this sort of system, a plate heat exchanger operates between the solar power system / collector and the pool you want to heat.

Heat exchangers can also be used to heat spa pools to a suitable temperature, ensuring that your spa is at the right temperature at all times. You can regulate the temperature with a heat exchanger for your spa or swimming pool. This can be done by heating a storage tank of water to 60 degrees C or more, giving a source of primary heat that allows you to heat the spa pool on demand. So, for example, if you had tank water that was heated to 60 degrees, you could heat your spa efficiently and cost-effectively to about 40 degrees without much trouble.

In the example shown, a Sondex S1 plate heat exchanger operates between the spa pool and circulating hot water from the storage tank. In the picture shown, the spa is bromine tablet treated so the plate heat exchanger isolates that water from the clean stream.

The heat exchanger is fed off the filtering loop with a manual valve to control how much flow goes through. The storage tank means you can use the spa day or night if the tank water is hot. The controller on the wall is on a timer to regularly put heat into the spa, but you can manually override this as necessary to heat the spa at other times.

Heat exchangers greatly benefit swimming pools or spas, whether you use them in a domestic or commercial setting.
