How to choose a floor heating circulation pump
With the advent of winter, the frequency of use of floor heating systems gradually increases. As one of the core components of the floor heating system, the choice of the floor heating circulation pump directly affects the heating effect and energy consumption of the floor heating. This article will combine the hot topics and hot content on the Internet in the past 10 days to give you a detailed introduction to how to choose a floor heating circulation pump.
1. The function of floor heating circulation pump

The main function of the floor heating circulation pump is to promote the circulation of hot water in the floor heating pipes to ensure that the heat is evenly distributed to each room. An efficient floor heating circulation pump can improve heating efficiency, reduce energy consumption, and extend the service life of the floor heating system.
2. Key factors in choosing a floor heating circulation pump
When choosing a floor heating circulation pump, you need to consider the following key factors:
| factors | Description |
|---|---|
| traffic | Flow refers to the amount of water that the circulation pump can deliver per hour, in cubic meters per hour (m³/h). The flow rate needs to be calculated based on the pipe length of the floor heating system and the area of the room. |
| Lift | The head refers to the pipe resistance that the circulating pump can overcome, in meters (m). The lift needs to be determined based on the pipeline layout and height difference of the floor heating system. |
| Power | Power determines the energy consumption of the circulation pump, measured in watts (W). Too much or too little power will affect the system efficiency and needs to be selected according to actual needs. |
| noise | Noise is an important factor that affects the user experience. It is recommended to choose a circulating pump with a noise lower than 40 decibels. |
| Brand and after-sales | Choose products from well-known brands to ensure quality and after-sales service. |
3. Common types of floor heating circulation pumps
According to the working principle and structure, floor heating circulation pumps are mainly divided into the following two types:
| Type | Features |
|---|---|
| Fixed frequency circulation pump | The running speed is fixed and the price is low, but the energy consumption is high. It is suitable for users with small apartments or limited budgets. |
| Frequency conversion circulation pump | The running speed is adjustable, the energy saving effect is significant, and the noise is low. It is suitable for large households or users with high comfort requirements. |
4. How to calculate the required flow rate and head
In order to ensure that the selected floor heating circulation pump can meet the needs, it is necessary to calculate the flow rate and head of the system. Here is a simple calculation:
| parameters | Calculation formula |
|---|---|
| traffic | Flow (m³/h) = total heat load of floor heating system (kW) / (water temperature difference (℃) × 1.163) |
| Lift | Lift (m) = total pipe resistance (Pa) / (density of water (kg/m³) × acceleration of gravity (m/s²)) |
5. Popular brand recommendations
According to the hot topics and user reviews on the Internet in the past 10 days, the following floor heating circulation pump brands have attracted much attention:
| Brand | Features |
|---|---|
| Grundfos | Danish brand with high product quality, good energy saving effect and low noise. |
| Wilo | German brand, mature technology and perfect after-sales service. |
| New Territories | A well-known domestic brand with high cost performance and suitable for users with limited budget. |
6. Installation and maintenance precautions
1.Installation location: The circulation pump should be installed on the return pipeline to avoid the impact of high temperature on the pump body.
2.Regular inspection: Regularly check the operating status of the circulation pump to ensure there is no abnormal noise or vibration.
3.Cleaning and maintenance: Clean the filter regularly to prevent impurities from clogging the pipes.
7. Summary
When choosing a floor heating circulation pump, you need to comprehensively consider factors such as flow, lift, power, noise, and brand after-sales service. Through scientific calculations and reasonable brand selection, you can ensure that the floor heating system operates efficiently and bring you a comfortable heating experience in winter.
