Jinyi High Quality 150L solar Herter Copper Coil Pre heated Vacuum Tube Solar Water Heater With Assistant Tank

working principle

Ideal for use as low pressure thermal stores, the JINYI pre-heating solar hot water heater is available with the addition internal coil heat exchanger. 
JINYI “Pre-heating” 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 45m-60m copper 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.
