 Pre-heated Solar Water Heater (200 liters)





JINYI solar offers a range of high quality tanks designed especially for "Pre-heated". These tanks can be used in combination with existing electric/gas mains pressurized water heating system, or even as stand alone low pressure hot water systems with the addition of electric elements or external gas boosting.
Ideal for use as low pressure thermal stores, the JINYI pre-heated solar water heating system available with the addition internal coil heat exchanger.
JINYI Pre-heate solar water heater provide mains pressure via a high efficiency copper coil heat exchanger located within the 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, the type uses a 30m-40m coil. A heat exchanger inside the tank provides more than 1.2m² of heat transfer area.
When cold water flows through the coil it absorbs heat from the water inside the pre-heating tank. The tank is therefore a thermal store.
