Connecting pipes: The solar water heater first enters the hot water storage tank, and then transfers the heat to the insulated water tank through the collector. The hot water storage tank is connected to the indoor cold and hot Solar water heater pipe, so that the whole system forms a closed loop. Reasonable design and correct connection of solar pipes are crucial to whether the solar energy system can achieve the best working state. Solar pipes must be insulated. In cold northern regions, heating cables need to be laid on the outer wall of the pipe to ensure that users can use solar hot water in the cold winter.
Control components: Generally, household solar water heaters need to operate automatically or semi-automatically, so control systems are indispensable. Common controllers are automatic water supply, water supply cut-off when full, and display of water temperature and water level. Solar water heaters with electric auxiliary heating also have leakage protection, anti-dry burning and other functions. There are intelligent solar water heaters controlled by mobile phone text messages on the market, which have functions such as water temperature and water level query, fault alarm, water supply start, water supply stop, electric heating start, etc., which are convenient for users.
