1)Compact pre-heating solar water heater with EN12976 certificate,2)Copper coil with 14mm diameter and 1mm thickness
Working principle of Compact pre-heating solar water heater:
EN12976 copper coil solar water heater 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.
Specification of compact pressurized solar water heater:
1. Water tank: Inner tank with Anti-corrosion SUS304-2B Food Grade stainless steel plate, tank capacity:150-350L, Red copper coil inside tank as heat exchanger.
2. Outer shell: Anti-corrosion Power coated galvanized color steel plate or SUS304-AB stainless steel plate
3. Bracket: Anti-corrosion galvanized color steel plate or stainless steel plate
4. Tank insulation: Polyurethane integral foaming, 55-60mm thickness
