Product Introduction
The working principle of preheating solar water heaters is primarily based on solar collectors absorbing solar radiation energy, transferring heat to water through heat exchange, and utilizing natural circulation or forced circulation to achieve continuous hot water supply.
Demax Solar offers a range of high quality tanks designed especially for "Pre-heating". These tanks can be used in combination with existing electric/gas mains pressure water heaters, 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 pre-heating solar hot water heater is available with the addition internal coil heat exchanger.
Main features
The features of Vacuum Tube Pre-Heated Solar Water Heater:
Fresh hot water: the hot water are aways fresh. do not use the storage water.
Pressurized System: water flows out with pressure
Pressure endurance: Heat exchange coil can withstand 6-12 bar.
Pre-heated system can supply instant hot water: overcome the disadvantage of traditional system, such as slow heating, long time waiting.
High Efficiency: high efficient solar vacuum tube
More affordable: Compare to heat pipe pressure system, it has a more affordable price.
Eco-Friendly: renewable solar energy to heat water
