solar system--Closed Loop Solar Water Heater with Copper Coil provides mains pressure pre-heating via a highly effective copper coil heat exchanger located within the solar water tank. the way in which the mains pressure solar collector heats water is the same as the non pressure solar collector. rather than using the water in the tank directly, as the non pressure does, this type uses a 45-60m copper coil. Heater exchanger inside the tank provides more than 1.5m2 of heat transfer area. when water flows through the coil it absorbs heat from the water inside the solar collector tank. the solar collector tank is therefore a thermal store.
Copper coil heat exchanger specification:
1.HE material: 14mmx1.0mm copper pipe
2.HE surface area: 2.5m2 for 30 tube water heater
3.HE testing pressure: 9 bar
4.HE net weight: 15kg for 30 tube water heater
