Heat exchangers transfer heat between two media without allowing them to come into direct contact. Make sure to size heat exchangers correctly, whether you need one for a snow melt or swimming pool application or to isolate open and closed hydronic heating loops. FlatPlate offers a website for heat exchanger sizing. Sign up for free here, and go to SupplyHouse.com to purchase FlatPlate heat exchangers.
Finding a properly-sized heat exchanger for a pool if not too difficult. Just find the capacity of the pool (length x width x depth x 7.5 for rectangular pools; diameter x diameter x depth x 5.9 for circular pools). Use the average depths for pools that do not have the same depth all the way around. Then, based on the pool’s capacity, consult the heat exchanger manufacturer’s literature to find the heat exchanger you need. The heat source involved in the application must be large enough to handle both the swimming pool’s heat load and the heat-loss to the surrounding area. Larger heat exchangers and heat sources are required when aiming for a 2°F (rather than 1°F) hourly heat-up rate. A 2°F/hour rate is recommended when the pool is only used periodically (weekends, holidays, etc). Visit SupplyHouse.com for swimming pool heat exchangers from FlatPlate and Triangle Tube.
