Heat pumps are the answer to problems resulting from rising fuel prices and high levels of environmental pollution. They are the most economical heating devices because, despite significant investment costs, they significantly reduce subsequent heating bills. If you are wondering how to power the central heating installation in your company or in the building you manage, be sure to read our review of heat pumps!
What is a heat pump and how does it work?
A heat pump is a device that draws heat energy from the environment and, with relatively little support from electricity, uses it to heat utility water or water circulating in the building's heating system. This means giving up a significant part of the energy produced from fossil sources in favor of clean, environmentally friendly renewable sources.
The use of renewable energy sources is constantly gaining in importance, because it allows independence from fuel suppliers. Electricity and gas prices have been rising dramatically recently, so it is worth considering an alternative to traditional heating devices. The heat pump market provides such solutions, which use 75% of the energy contained in the air, ground or water to produce heat, and only 25% of electrical energy.

Depending on the specifics and needs of the building, the pumps can operate independently or be supported by another heat source. The bivalent system works best when air heat pumps operate at very low temperatures. Some multi-family buildings will also benefit from it. Another solution for this type of facility with a high heat demand is cascade pump systems.
