This type of solar water heater provides main pressure pre-heatingvia a highly effective copper coil heat exchanger located within the solar collector tank. Rather than using the water in the tank directly, as the non pressure does, this type uses a *0 to *0m copper coil.Heat exchanger inside the tank provides more than 1.5m? of heat transfer area. When water flows though the coil, it absorbs heat from the water inside the solar collector tank. The solar collector tank is therefore a thermal store.
