Plate heat exchangers are used in settings that may be of interest to everyone, whether you need one for a domestic setting or in industry. For example, plate heat exchangers or brazed plate heat exchangers can be used in a craft beer brewery, in dairy farms, a meat works, or in a swimming pool.
With swimming pools, heat exchangers are able to 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.
Tank water for a pool could be heated by a range of means, such as 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.
They also act as a barrier to any contaminants or chemical treatment in the pool water.
In the system shown, a Sondex S1 brazed plate heat exchanger operates between the spa pool and circulating hot water from the storage tank. 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 the spa can be used 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 this can be manually overridden as necessary to heat the spa at other times.
With solar heating much more economic than it was in the past, something like this (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. 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.
If you want to regulate the temperature with a heat exchanger for your spa or swimming pool, ask us for options that might suit your situation and budget. There are a range of options to suit almost anyone.
