The equipment used can consist of machines used to remove heat such as a chiller or a cooling tower and equipment for adding heat to the building's water such as a boiler or a commercial water heater. Hydronic fan coil units can be generally divided into two types: Two-pipe fan coil units or four-pipe fan coil units. Two-pipe fan coil units ...
Chiller boiler systems use radiant heating and cooling or fan coil systems to condition a home or business. This allows for multiple zones (a thermostat in each living area of the house) for increased comfort and decreased energy use. Compared with air, water is a more space-efficient method of transferring heat around, into, and out of a building.
Pentair plc (PNR) is an American water treatment company incorporated in Ireland with tax residency in UK, with its main U.S. office in Golden Valley, Minnesota. [6] Pentair was founded in the US, with 65% of company's revenue coming from the US and Canada as of 2017.
The absorption-compression heat pump uses instead a binary mixture where the condensation and evaporation occur with a temperature glide. This property increases the efficiency of the heat transfer when the heat source also has a significant temperature glide, which is the typical condition found when dealing with waste heat recovery.

Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.
Chillers in a district cooling at University of Rochester in Rochester, New York. District cooling is the cooling equivalent of district heating.Working on principles broadly similar to district heating, district cooling delivers chilled water to buildings like offices and factories.
