Choose between 0.75 and 0.85 MPa. The size of the water heater pressure relief valve can be adjusted according to the relevant information. When the vessel pressure exceeds the design requirements, the safety valve automatically opens to vent the gas to reduce excess pressure in the water heater and. avoid damage to the container or pipeline. The pressure of the water heater booster device is generally 0.6-0.75 MPa (tap water pressure is 1.4-3.0 kg). Generally, 60 liter water heaters use a 0.75 MPa pressure relief valve. Don't underestimate this little accessory, it plays a very important role. Pressure relief valve is also called one-way valve. It allows tap water to flow only into the water heater and prevents the water inside from flowing back into the tap water line. thermal expansion, internal pressure increasesra. If the pressure exceeds the design pressure of the pressure relief valve, the pressure will be released from the pressure relief hole next to the pressure relief valve, ensuring that the electric water heater will not operate. explode due to thermal expansion.
In real life, when purchasing a water heater, you can choose different types of water heaters according to your own needs. Currently, the existing types of electric water heaters include electric water heaters, gas water heaters, solar water heaters and air-to-energy water heaters. Today we will focus on understanding what to do if the solar water heater pressure is unstable? Where is the solar water heater booster pump installed?
Usually, there are three effective ways to solve the problem of unstable water pressure in solar water heaters. The first method is to install a pumpe overpressure on the water heater pipe. This method is the most common solution to solve the problem of unstable water pressure in solar water heaters, and it is also a relatively effective solution at present. The second method is to use a pressurized water tank when installing a solar water heater. Pressurized water tanks are more stable than regular water tanks. The third method is to install a thermostatic mixing valve to ensure that the outlet water temperature is not affected by changes in water temperature, water flow and water pressure.
Generally speaking, most solar water heaters install a booster pump to keep the pressure of the water heater stable during use. So, where is the solar water heater booster pump installed? Most solar water heaters you see todayns living must be installed on the roof of the building and the booster pump is located directly behind the water meter. When purchasing, you don't need to worry about whether you should buy a general water pump or a specialized booster pump for solar water heaters, because the functions of the two are basically the same and it does not There's not much difference.
The above is a complete explanation of what to do if the solar water heater pressure is unstable and where to install the solar water heater booster pump. I hope this can be helpful to you! In summary, if the pressure of the solar water heater is unstable, in principle it is sufficient to install a booster pump to solve the problem. If you have any questions about unstable pressure from solar water heaters, don't hesitate to ask!
