Product Description

Pre-heating system with copper coil in the tank offers a unique heat transfer system which enables you have instant hot water from your pre-heating tank. During the day, the copper coil was heated by the hot water. When hot water is demanded, the cold water flows through the copper coil and proceeds to flow to the hot water demand. It's the best solution for the area where the water quality is inferio. LISHENG Pre-heating solar water heater provides mains pressure via a high efficiency copper coil heat exchanger in 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 *5m**0m copper coil. A heat exchanger inside the tank provides more than 1.2m 2 of heat transfer area. Key features: 1 It can withstand pressure of tap water when it works, and copper coil in tank bear pressure; 2 There is no need to wait and hot water is available immediately; 3 Integrated and pressure solar water heater is equipped with a electrical heating system; 4 Temperature preservation can last for *0 hours; 5 Without incrusting, long usage life; 6 Storage tank is used to boil copper coil; 7 It can produce hot water with constant temperature, it is safe and comfortable to use.
