Pump groups connect the heat supply system, usually a boiler, to the consumer circuits, such as underfloor heating or radiators. Pump groups are always equipped with a pump and enclosed in a compact, well-insulated casing. They are used in installations divided into several heating circuits, where constant temperature control and efficient energy use are required, and they ensure the correct operation of equipment requiring different heating medium parameters, such as traditional radiators and low-temperature wet underfloor heating. Compared to simple pump groups, double pump groups allow the connection of two different heat sources, for example a gas condensing boiler and a solid fuel boiler, which requires protection against excessively low return water temperature from the heating unit. Various pump group models are available, with equipment depending on the level of sophistication, purpose and operating conditions. The units are offered with a three-way thermostatic mixing valve for constant temperature control in the heating circuit. Depending on the pump group model, they may be equipped with various control valves. Also take a look at the range of manifolds and accessories for pump groups.
