How a recirculating pump for heating works
A circulation pump for the heating is responsible for pumping the hot water in the entire house circuit. The heating circuit is a closed circuit which itself does not have sufficient power to circulate hot water. For this reason, all boilers contain a circulation pump, but an additional pump may be required for support depending on the type of installation.
The installation of a recirculating pump for heating is very simple, just take into account a number of recommendations:
- The pump is located in the hot water rising main, as close as possible to the boiler.
- It must be connected to the electric current and in series with the boiler pump so that it works simultaneously with the boiler.
- If the system is divided into several zones, it makes more sense to use a circulation pump for heating in each zone.
- Choose the right size for the pump, i.e. do not exceed the recommended pressure or fall short.
Selection of a suitable circulation pump for the heating system
As with all types of water pumps, when selecting a circulation pump for sufficient heating, it is necessary to adapt to the needs of the system. If we choose a pump that is too small, the pressure is not sufficient and parts of the circuit remain unheated.
However, if we choose a too big one, the pressure will be excessive and can produce noise and wear in the pipes, even leading to leaks.
To determine the most suitable size of the pump, we need to focus on the energy requirements of the installation, as its function is to transport heat and rather than transporting water.
On the market you will find the right circulating pump for the heating system for every type of installation, in size and speed.
