Yes. Today's wall-mounted boilers are essentially designed with these issues in mind. They can be combined with a variety of water heating equipment. You just need to tell the merchant who sells wall-mounted boilers. If you want to connect solar energy, they will give you a corresponding design. It simply adds a few small accessories, a thermostat and a set of electric valves. Once the installation is complete, the system will automatically adjust whether or not a wall is used. Boiler mounted or solar energy depending on water temperature. , set a certain temperature when the temperature provided by solar energy is enough to support your usage, the system actively selects solar energy when solar energy is not enough to support the heat consumption. the system will start the wall boiler to provide you with heat! The principleThis is that you need to install a large insulated water tank to store the heat absorbed from the sun based on your own solar panels and your daily heat consumption.
How to switch water between a solar water heater and a wall-mounted boiler
How do you want to connect? The water system of the wall boiler is separate, that is, the heating system and the hot water system are separate.
1. Solar hot water enters the heating system. This is not easy to achieve, because the wall boiler heating system must be a closed system, have a certain working pressure (usually 0.5 - 1.5 MPa) and also be connected to a series of components such as a circulation pump. It is therefore not easy to connect to solar energy.
2. The solar hot water is connected to the domestic hot water system of the wall boiler. Water outlet temperaturedomestic hot water from wall-mounted boilers is 30 to 60°C, while the outlet temperature of solar hot water is generally above 90°C in summer. In winter, when the sun shines, the temperature exceeds 60°C. Mixing the two for domestic hot water doesn't make much sense.
3. If you have installed solar energy for domestic hot water and now want to install a wall-mounted boiler for heating, you have two options:
Option 1: You can use solar energy The output of The water is connected in parallel with the domestic hot water outlet of the wall-mounted boiler, and a check valve is installed to prevent hot water from the wall-mounted boiler from entering the solar. In good weather, solar energy is used to provide hot water, and when the weather is bad, a wall-mounted boiler is used to provide hot water. The system will be a bit complicated.
Option 2: Aseparate water supply and use of solar energy for washing face and vegetables in areas with low water consumption. Wall-mounted boilers are used in places with high water consumption, such as baths, to avoid frequent flooding of water by solar energy.
Close one.
According to official surveys, when changing the water source for solar water heaters and wall-mounted boilers, one of the water sources must be shut off.
The solar water heater is a heating device that converts solar energy into thermal energy, heating water from low temperature to high temperature to meet the use of hot water by people in life and production. According to the structural form, it is divided into vacuum tube solar water heaters and flat plate solar water heaters. Evacuated tube solar water heaters are mainly used, representingt 95% domestic market share.
