EN12976 compact pre-heated thermosyphone solar water heater system provides main pressure pre-heating via 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 45 to 60m copper coil.Heat exchanger inside the tank provides more than 1.5m² of heat transfer area.
When water flows though the coil, it absorbs heat from the water inside the solarcollector tank. The solar collector tank is therefore a thermal store.
