Solar water heaters in series connection
Cold water pass the water level control box then flow into the solar water heater, the selective absorbing layer in the vacuum tube absorb heat for heating up the cold water The user may through the addition in the water heater the temperature induction and in the display unit knowing solar-powered water heater's water temperature, when the water temperature achieves the taking a bath temperature then turns on the hot water switch to use the hot water. The rain weather, may through the electricity heating to the water heater warming.
Characteristic:
The structure is simple, namely exposes to the sun namely uses, to be suitable for the water volume is small, and to hot water request not high company, unit and individual.


Connected vacuum tube solar collectors project
The system Includes solar collectors, heat storage water tank assistant heating system ,In hot-water systems Through control of some facilities and the use of auxiliary heat to meet the user from time to time, or all-weather, temperature and other quantitative and water demand. By Scale (Scale magnetization), antifreeze (antifreeze recycling or piped-assisted self-limiting temperature electrical heating), leak-proof electrical (grounding system security and protection of highly sensitive residual current switch), mine (metal steel lightning protection facilities and buildings electrical connection) and other specific facilities to ensure reliable operation of the system, users safe for use.
Characteristic:
System operation stable performance, collector area, suitable for large-scale factory schools such as the need for central heating.
