The gas water heater's ignition setting is to turn on when it senses water flow in the pipe. If your bathroom flush valve is not connected to the water heater, I think it may be that when the flush valve is turned on, the water in the gas water heater is impacted , causing the water heater to ignite. To resolve this problem, you can try opening the valve slowly to see if the problem can be resolved. You can install a switch in the toilet pipe so that the toilet does not catch fire when water is used. Today's water heaters all turn on automatically, so they are hot as soon as they are turned on. Your pipes are open, so they catch fire when the toilet consumes water. It is recommended to check the pipes or turn off the water heater when not in use.
Diagram of the operating principle of the solar water heater 1.Cold water enters the solar water heater through the pipe, passes through the heat collecting plate and the heat collecting plate can collect solar energy, convert solar energy into thermal energy. energy, then heat the cold water. Since the density of cold water is higher than that of hot water, the hot water will automatically increase and then form circulating power. The water will gradually heat up on the heat collecting plate. After reaching a certain temperature, it can enter. the hot water tank. Those who need hot water will be able to get hot water at any time. Heating Figure 2. In fact, the principle of solar water heaters mainly includes the following two principles: (1) The principle of water circulation, that is, the water flows automatically. This is based on the fact that cold water is denser than hot water. Cold water flows and water cheat rises, forming natural convection that gradually heats the water in the water tank until it reaches the set water temperature. When the intensity of the sun is not sufficient to meet circulation needs, a water pump can be added to the closed water circulation circuit to obtain forced circulation. (2) Collector heat absorption principle: There is a special coating on the collector surface of the solar water heater. This coating has a high absorption rate in the visible range of solar energy. After absorbing it in the form of heat, heat. the radiation from the collector will have the wavelength in the longwave range and the coating has very low longwave emissivity, thus effectively retaining solar heat. This heat is then used to gradually heat the cold water into hot water. Solar collector tube Let's talk in detail about the collect tubeeur on this collector. The collector tube is actually like an elongated hot water kettle liner. It is made of two glass tubes, one large and one small. the inner layer is covered with a spectrally selective absorption coating and a straight void is drawn between the inner and outer tubes. It forms the core of the solar water heater and is used to maximize the absorption of thermal energy after solar radiation due to vacuum. The glass tube is round, has the characteristics of naturally following the wide source of the sun, coupled with the reflection principle of the reflector, the glass tube can receive light from all sides, the heat collection effect lasts longer , the water temperature is higher, and it can work normally all year round, even in alpine areas.
