How to install electric heating boilers
1. Confirm the installation location and reserve holes in the installation location according to the installation requirements.
2. Take out the electric heating boiler, check whether the machine is damaged or not, and check whether the accessories are complete. Confirm whether the machine is consistent with the installation requirements, if not, it should be replaced in time.
3. Drill holes for drain pipes and hanging stoves. If it is an outer wall and has a thick and light body for heat preservation, use larger and longer expansion bolts to fix the hanging board.
4. Fix the electric heating boiler with screws and make a good support.
5. Install drainage pipes. The installation of drainage pipes must meet the design requirements and must not leave hidden safety hazards.
6. Connect the drain pipe to the electric heating boiler, connect the power supply and the indoor temperature controller. Open the front panel of the machine, connect the power according to N, L, E, connect the 1-3 contacts according to the requirements of the temperature controller, and install the panel.
7. Fill water and check for leaks, turn on the tap water inlet switch, turn on the water filling switch, and fill the heating system with water until 3Bar, turn off the water filling switch to see if there is a leak, and pay attention to whether the safety valve is depressurized.
8. After the inspection, turn off the tap water inlet switch, electric heating boiler faucet, and let off part of the water in the heating system until the water pressure drops to about 1Bar, and the installation is completed.
What to pay attention to when installing a heating boiler
1. The highest point of the water supply pipe of the heating boiler should not be higher than 6 meters from the return port of the boiler, otherwise it will cause pressure If it is too large, the protective body will be deformed. A pressure reducing pipe should be installed at the water outlet of the heating furnace. Its diameter should not be less than the pipe diameter.
2. An expansion water tank needs to be installed in the heating furnace system, and the height of the water tank should be above 250mm at the highest point in the system. The water inlet and outlet are connected by live connection, which is convenient for maintenance.
3. It is strictly forbidden to install valves on the decompression pipe, exhaust pipe and water supply tank, which is very dangerous. The height of the center of the radiator should be more than 300mm higher than the center of the inlet and outlet of the furnace body, the higher the better, which is conducive to circulation.
4. When the circulation is not good due to non-gas-blocking reasons such as too long pipelines, the position difference between the heating furnace and the radiator can also be further increased to promote water circulation, otherwise small hot water should be added In-line pump forces the water to circulate.
Tips for using electric heating boilers
1. When the electric boiler controls the indoor temperature, the room temperature should be controlled within an appropriate range. Generally, it is recommended The temperature setting is too high, which will consume too much heat, and also cause the temperature difference between indoor and outdoor to be too large, which will cause people to catch a cold when they walk from indoors to outdoors. Design the water temperature of the electric boiler to 65°C, temperature difference 20°C (radiator) or water temperature 50°C, temperature difference 10°C (floor heating).
2. In the area that needs long-term heating and heating, do not turn the electric boiler on and off regularly, because the electric boiler needs to slowly increase the temperature during heating operation, so it is recommended to keep the water at 20 ℃ The standby temperature can be left and right, so that the heating is faster, and the problem of pipeline damage when no heating is avoided.
3. It is best to install an intelligent control system when installing an electric boiler, so that the electric boiler can adjust the temperature according to the change of time, so as to achieve the best energy-saving heating purpose, For example, you don’t need too much heat after going to bed at night. In this case, you can lower the room temperature. During the day, the user also lowers the temperature after going out to work. Compared with the constant heating operation at the same temperature, the temperature can be reduced a lot. energy expenditure.
4. The electric boiler needs to be vented regularly during the heating process, because the water will release gas during the heating process, and the user also needs to replenish the water regularly, and a lot of gas will be generated over a long period of time. In this case, it is necessary to open the exhaust valve to release the gas to improve the heating effect.
