How to add a circulation pump for floor heating: comprehensive analysis and operation guide
As winter approaches, the frequency of use of floor heating systems gradually increases. However, many users report that the heating effect of the floor heating system is poor, which may be due to insufficient power of the circulation pump or improper installation. This article will introduce in detailFloor heating plus circulation pumpMethods, precautions and related data to help you improve the heating efficiency of your floor heating system.
1. Why is it necessary to add a circulation pump?

The circulation pump of the floor heating system is responsible for circulating hot water through the pipes to ensure that the heat is evenly distributed. If the circulation pump power is insufficient or damaged, it will lead to uneven heating in some areas and a drop in water temperature. Installing a circulation pump can effectively solve these problems and improve the heating effect.
2. Selection of circulating pump
The following parameters need to be considered when selecting a circulation pump:
| parameters | Description | Recommended value |
|---|---|---|
| traffic | The amount of water circulated per unit time | Calculated based on heating area (usually 0.5-1.5m³/h) |
| Lift | The resistance height that the water pump can overcome | 3-6 meters |
| Power | Water pump power consumption | 25-100W |
| noise | Noise level during operation | ≤40dB |
3. Steps to install a circulation pump
1.Determine the installation location: The circulation pump is usually installed on the return pipe, close to the water distributor.
2.Turn off system power and water: Ensure safe operation.
3.cutting pipe: Cut the pipe at the selected location to reserve space for the pump installation.
4.Install pump body: Connect the circulation pump to the pipe, paying attention to the direction (the arrow points to the direction of water flow).
5.Wiring: Connect the power cord according to the instructions and make sure it is grounded.
6.test run: Turn on the system and check the operating status of the pump and the heating effect.
4. Precautions
1.Match system requirements: When selecting a circulation pump, it must match the flow rate and lift of the floor heating system to avoid being too large or too small.
2.Regular maintenance: Clean impurities in the pump, check sealing, and extend service life.
3.Noise control: Pay attention to fixing the pump body during installation to reduce vibration noise.
4.Safety first: Be sure to turn off the power and water source during operation to avoid electric shock or water leakage.
5. Frequently Asked Questions
| question | Reason | Solution |
|---|---|---|
| Circulation pump not working | Power is not connected or the pump is damaged | Check the power supply and replace the pump body |
| Uneven heating | Insufficient pump power or blocked pipes | Replace the pump with a higher power and clean the pipes |
| Too much noise | Pump is not secured or bearings are worn | Reinforce installation and replace bearings |
6. Summary
Installing a circulation pump is an effective way to improve the heating effect of the floor heating system. Through rational selection of pump parameters, correct installation and regular maintenance, indoor temperature uniformity and comfort can be significantly improved. If you are not familiar with the operation, it is recommended to contact a professional for installation to ensure safety and effectiveness.
