Accelerate further or slow down already: at what speed should the heating pump operate?
All modern heating systems are equipped with a circulation pump. With the help of which, what's going on in the pipes continuous circulation of hot water, as a result of which the room heats up.
They are available in different configurations and can have 3 speeds: minimum, medium and high.
What speed should be set on the heating pump when the boiler power is low?
Adjustment of the circulation pump power is usually carried out with the aim of increasing or, conversely, decreasing its productivity. The higher its speed, the faster the hot water passes through the pipes and the more heat it gives off. In turn, the lower it is, the slower the liquid passes through the system, cools down faster and, accordingly, the heat transfer will be less.
Minimum power heating equipment is installed mainly in springAt this time it is already quite warm outside, but the house itself is not warmed up enough and there is a need for a little heating of the room.
Pump speed modes may vary depending on the model and configuration. On average minimum indicator makes up 30-35 l/min, maximum - 80-90 l/min.
Why you need to check the settings
To ensure maximum performance of the device before starting operation it is recommended to check its settings. This is usually done by two parameters.
Soundproofing. There are several reasons why a heating appliance may make a lot of noise:
- incorrect installation;
- air in the pipes;
- voltage surges;
- device malfunction.
To avoid these problems, it is better to entrust the installation to a specialist who will conduct a comprehensive diagnosis, ensure the correct installation and functionality of the device.
Uniform heating. The main reason for uneven heating of radiators is insufficient power. Low speed contributes to rapid cooling of water, as a result of which heat simply does not reach the end of the system.
A similar problem also occurs airiness or incorrectly selected mode thermostat. May affect the performance of the appliance and incorrect installationThis is especially true for aluminum and bimetallic batteries, which must be installed as level as possible.
How Electronically Controlled Circulation Pumps Should Work
Models with electronic heating type have two types of adjustment speeds: manual and automatic. Manual Regulation involves setting the device's power at the required level. Pressure drops are not adjusted.

In the case of automatic The speed is reduced or increased by the system itself and directly depends on the temperature in the pipeline. The autopilot itself determines the optimal level of performance and, if necessary, reduces energy consumption without reducing productivity.
Important! Automatic pump speed reduction is possible only after hydraulic balancing systems.

A change in temperature outside is a reason to switch to a different speed
The presence of several modes in the heating pump will allow adjust the heating level in a particular room. This function is important when there is a sharp change in temperature outside. In this case, the device can be manually switched to the required power or the autopilot can be turned on, and the system will automatically adjust to the desired temperature.
