30 Plate Water to Water Brazed Plate Heat Exchanger 1" FPT Ports

These are true 5" x 12" Units, if hooking up to an indoor boiler do not settle for anything smaller in width or length. These are made of 304L Stainless Steel and are UL listed. These are an expensive item and no reason to have to replace them sooner than needed. Not to be used for transferring steam! Plates should be mounted vertically but can be placed horizontally if space does not allow. We provide a limited lifetime warranty against manufacturer's defects. These are used for transferring heat from one hot water source to another without mixing the two different water sources. For example when hooking up a non pressurized furnace to an indoor boiler or for heating cold water before it goes into the hot water heater to eliminate the need for fuel to power your water heater.
