Exchanger type heaters; connects your pool to your central heating system by connecting it like a radiator to central system that you use to heat your home. It provides connection for heating pool water for your natural gas or oil-fired system which is specially built for pool. Plate heat exchangers are a type of heat exchanger that uses plates with different folds on metal to transfer heat between two different systems. System design can be improved, applied to larger pools, and switching of more than two systems from same exchanger can be provided. The heat transfer area and therefore transfer speed are higher than those tubular type heat exchangers. For this reason, they are preferred as the most efficient system solution. However, it is more likely to be affected by chemical agents such as chlorine.
