1. The use technique of solar water heater.
1, Taking a bath, if the water in solar water heaters are used up, and people also not rinse, then can take a few minutes to the cold water, use cold water sinks the principle of hot water to rise, will the water in the vacuum ejector, can then take a bath.
2, The weather forecast determines the amount of water, which can be satisfied with the water temperature. If it is sunny the next day, the water will be full, cloudy or cloudy. If there is rain, keep the original water without cold water.
3, After the shower in the evening, if the water heater tank and half nearly 70 ℃ hot water, in order to prevent heat loss is too large, the faster the less water, heat dissipating), also it will be decided according to the weather forecast on the water; The next day was sunny, and the water was full; On a rainy day, it's 2/3 water.
2, Causes and treatment methods of unheated water in sunny days?
1, The water heater is covered with occluded objects, or the local air dust is much, and the surface of the collector is dusty. Treatment: remove the occlusion or re-select the location of the installation, seriously polluted areas, the user should regularly wipe the collector tube.
2, The upper water valve is not tightly closed, and the tap water (cold water) pushes the hot water out of the water tank to reduce the water temperature. Treatment: repair or replace the upper water valve.
3, Causes of water failure and treatment methods on water tank?
1, Insufficient water pressure. Treatment: add an automatic suction pump.
2, Water leakage in the upper and lower water pipes. Treatment: replace pipe valve or connector.
4, What are the antifreeze measures for solar water heater pipeline?
1, It's extra thick insulation;2, Electric heating and heating;3, Internal heating wire;4, The surface treatment of self-absorption heat defrost of special pipes;5, A drain valve in an empty pipe.
5, Which areas need anti-freeze measures?
Answer: in principle, every winter temperatures lower than 0 ℃, when installing a solar water heater, are certain outdoor pipeline heat preservation measures should be taken. Specific measures should be based on the minimum temperature of the seasons. In general, south, southeast and southwest lowest temperature above 0 ℃, pipeline without additional insulation pipe; Vast area north of the pearl river south of the Yangtze river, the lowest temperature in winter in - 5 ℃ above, the pipe heat preservation adopts single rubber or polyethylene pipe can ensure the normal use, the lowest temperature in winter in north of the Yellow River to the south of the Yangtze river region - around 15 ℃, the pipe heat preservation more appropriate USES of polystyrene insulation pipe insulation winterization, if winter low temperature duration is long, can consider to strengthen heat preservation measures such as double insulation or antifreeze electric heating.
North of the Yellow River to the south of liaohe area, the lowest temperature in winter in more than 20 ℃, the line should give preference to double insulation heat preservation or add antifreeze electric heating, liaohe area north of the winter minimum temperature under - 20 ℃, advocated by way of double insulation, can add antifreeze electric heating, multiple antifreeze protection, ensure that use all the year round. Advocate pipeline to walk flue, if do not go flue, the insulation measure should rise a class (press northward area processing).
Note: because the temperature is affected by the coastal and topography, the above zones are only for reference. The insulation measures should be based on the local minimum temperature.
6, Which parts of solar water heater are anti-freezing point?
1, And the three of them;2, The corners, the corners, the corners;3, The joint of the pipe and pipe;4, To wear a wall. Generally speaking, all exposed pipes should be insulated.
