Rating of the best circulation pumps for heating systems
Heating systems are of two types: with natural and forced circulation. The first type is relevant for houses, the area of which does not exceed 100 m². With a larger area, uniform heating of all radiators is impossible. The coolant will not move well through the pipeline, which will inevitably provoke large heat losses.
The circulation pump, which is part of the second type of heating system, ensures the movement of the coolant through the heat supply system at a certain speed. During the installation process, it is not necessary to control the slope of the pipes, which may have a smaller diameter. Thanks to the injection circulation, it is possible to ensure uniform heating of various points of the heating circuit, and, as a result, all rooms, regardless of their location relative to the boiler. The DHW circulation pump allows you to maintain the water pressure at a given level.
