Pre-heated Solar Hot Water Heater
Our pre-heated solar hot water heater model also is pressure solar water heater but is cheaper than heat pipe pressure model. Pre-heated solar hot water heater also use non-pressure water tank and glass vacuum tube, but there is copper coil inside the tank which can bear much pressure, so it also can be called pressure solar hot water heater. Besides, pre-heated solar hot water heater you can get more hot water than common models.
