A heating-circulation pump plays an essential role in keeping your home nice and warm. This pump forms the core of the home heating system and provides transport of warm water to all heating appliances. This kind of pump also ensures optimal heat control.
Whereas it was previously customary to use self-circulating heating systems, a circulation pump is more common these days. The type of pump depends on the boiler model; either a wall gas boiler or a standing gas/oil boiler. A wall gas boiler usually operates with a special integrated pump, which is often manufactured in cooperation with the boiler manufacturer. On the other hand, the standing gas/oil boilers are available in many types, allowing the pump to be placed both inside or outside the cabinet. When using a reset function during the night, the pump must be placed on the inlet.
A heating system can be considered a closed system, which uses an (open) expansion vessel. These expansion vessels are like pressurised water vessels, in which water and any air are separated by a membrane. The water in these vessels can therefore expand and absorb shocks.
Energy efficient circulation pumps
The role of a circulation pump in home heating systems is relatively easy to understand. The pump takes care of transporting hot water through radiators in your home, the tap in your kitchen, shower, etc. In doing so, standard circulation pumps have a fixed (rotational) speed, which you canset to three different positions in advance. Automatic circulation pumps on the other hand have a variable (rotational) speed, which is much more efficient.
However, this is not the only reason to opt for an automatic pump. The fact that most heating systems use thermostat valves to control the flow of water through radiators makes automatic circulation pumps highly appealing. Should you require the full heating capacity, the valves can open to allow for a complete flow of water. If the temperature is lower, these same valves will slowly close or remain partially closed. Due to the variable speed, the pump never generates too much pressure and energy consumption is therefore lower.
Electronic controlled pumps comply with certain directives, which apply throughout Europe. For example, these pumps may provide a maximum of 80% savings compared to a D-label pump. Investment in a heating system with such a pump is often recouped after about two years.

Setting up a pump yourself
Smart operation and adaptive features are what distinguish modern circulation pumps from conventional ones. Modern pump systems analyse heating patterns in the home and adjust their operation accordingly, depending on the system requirements, of course. If we look at the situation a little more technically, we could say that the pump anticipates the correct head rate in order to meet the system requirements. Because the head rate is never too high as a result of this, such pumps will consume less energy.
