How to circulate hot water in wall-hung boiler
As winter approaches, wall-mounted boilers, as important equipment for home heating, have attracted much attention for their hot water circulation function. This article will introduce in detail the working principle, common problems and solutions of hot water circulation in wall-mounted boilers, and attach data on recent hot topics for reference.
1. Working principle of hot water circulation of wall-hung boiler
The hot water circulation system of the wall-mounted boiler mainly drives water flow through a water pump to transport the hot water to various heat dissipation terminals (such as radiators or floor heating pipes), and then returns to the wall-mounted boiler for reheating. The following are its core components and functions:
| components | Function |
|---|---|
| water pump | Driving hot water to circulate in pipes |
| heat exchanger | Transfer heat from combustion to water |
| thermostat | Monitor water temperature and adjust heating intensity |
| expansion tank | Balance system pressure to prevent excessive water pressure |
2. Common problems and solutions
1.Poor hot water circulation: The pipe may be clogged or the water pump may be faulty. It is recommended to clean the pipes regularly and check the operation of the water pump.
2.Water temperature is unstable: A malfunctioning thermostat or insufficient gas pressure may cause this problem. Thermostat settings need to be checked and gas supply is functioning properly.
3.The system is noisy: Usually caused by trapped air or worn water pump bearings. This can be solved by venting or replacing the water pump.
| question | Possible reasons | solution |
|---|---|---|
| poor circulation | Blocked pipes/water pump failure | Clean pipes/repair water pumps |
| Water temperature is unstable | Thermostat/Gas Issues | Calibrate thermostat/check gas |
| System noise | Air entrapment/water pump wear | Exhaust/replace water pump |

4. Suggestions for optimizing hot water circulation
1.Regular maintenance: System inspection should be carried out every year before the heating season, including cleaning filters, exhaust, etc.
2.Set the temperature appropriately: It is recommended that the indoor temperature be kept at 18-22℃ and the water temperature be set between 60-70℃.
3.Upgrade intelligent control: Installing a smart thermostat can improve energy efficiency by 10%-15%.
4.Pipe insulation: Install insulation layers on exposed pipes to reduce heat loss.
5. Summary
The hot water circulation system of the wall-mounted boiler is the key to ensuring the heating effect of the home. By understanding its working principle, common problems and optimization methods, users can effectively improve heating efficiency and reduce energy consumption. There has been a lot of discussion recently about energy-saving technology and intelligent control, which also reflects users' urgent need for efficient heating.
