High efficiency low pressure compact solar hot water heater
1. the coating inside of the vacuum tube absorbs the solar energy.
2. water inside of the vacuum tube is heated by the coating layer.
3. the vacuum tubes insert into the non-pressure tank, so the hot water and cold water can circulate by themselves because of different density.
4. non-pressure tank with PU layer keeps the water hot and store the water.
5. open loop type, hot water is supplied to the shower room because of water drop.
6. easy to install and high heat transfer rate over 95%.
7. if add the feeder tank, it could load the water automatically and reduce the water pressure.
