Many families install solar water heaters, so that when the weather is good, you can directly convert solar energy into heat energy to boil water, so you don’t need additional electricity for heating, and you can save electricity. Especially in summer, if the weather is good, the water temperature in the water heater will be very high, so that the hot water can be used for a long time. So why can’t the solar water heater produce hot water?
What if the solar water heater doesn’t produce hot water
1. The solar water heater leaks. The upper and lower water pipes, vacuum pipes and connectors can be inspected.
2. Check whether the water mixer, faucet and other water intake points in the room are leaking or not closed properly.
3. There is a lot of scale, and hot water cannot be produced due to blockage when using water. You can remove the nozzle and let it stand for a while to discharge the scale.
4. If it is automatic water filling, the probe may be faulty, and the probe can be repaired.
How to discharge hot water from solar water heater
When the water temperature in the water tank reaches the bath temperature, open the hot water valve or thermostatic valve nozzle to let the warm water flow out of the bath. If the outlet water of the nozzle is too hot or too cold, adjust the thermostatic valve or cold water valve until the outlet water temperature of the nozzle is appropriate. To adjust the water temperature of the solar water heater, first open the cold water valve, properly adjust the flow of cold water, and then open the hot water valve to adjust until the required bath temperature is obtained.
How to choose solar water heater
1. We should choose the products of professional manufacturers of solar water heaters, preferably high-quality brands, so that we can have excellent product quality and excellent after-sales service system and commitment.
2. There is a layer of thermal insulation material between the shell and the tank of the solar water heater, which plays a key role in the thermal insulation of hot water. The service life of polyurethane as thermal insulation material can reach more than 15 years. The tank is a place to store hot water
3. It does not mean that the higher the water temperature in the water tank, the better the thermal performance, but the higher the average daily efficiency, the better the average heat loss coefficient. Second, check whether the pressure test of the water heater is qualified. If the pressure test does not meet the standard, it is easy to cause water leakage of the water heater, waste hot water, and can not be used.
4. The support supports the frame of the collector and the insulated water tank. It is required to be firm in structure, high in stability, resistant to wind and snow, aging and rust. The materials are generally stainless steel, aluminum alloy or plastic sprayed steel.
5. Generally, the minimum domestic bath water is 30L for male and 40L for female. If the domestic water includes the kitchen, the total water consumption can be estimated at 40L per capita; The temperature of domestic solar water heater in winter is generally 50-60 ℃, which is converted into water heater capacity. The water volume depends on the actual purchase of the water heater.
