Hydronics (from Ancient Greek hydro- 'water') is the use of liquid water or gaseous water or a water solution (usually glycol with water) as a heat-transfer medium in heating and cooling systems. [ 1 ] [ 2 ] The name differentiates such systems from oil and refrigerant systems.
Domestic hydronic heating and cooling systems generally include an expansion tank to buffer pressure changes due to expansion and contraction of the water used for heat transfer. A minimum pressure of 28–34 kPa; 0.28–0.34 bar (4–5 psi) at the top of a closed hydronic system is suggested. [3]
A flow check is a check valve used in hydronic heating and cooling systems to prevent unwanted passive gravity flow. A flow check is a simple flow lifted gravity closed heavy metal stopper designed for low flow resistance, many decades of continuous service, and to self-clean the fine particulates commonly found in hydronic systems from the ...
Warman centrifugal pump in a coal preparation plant application A pair of centrifugal pumps for circulating hot water within a hydronic heating system. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine ...
A central heating system provides warmth to a number of spaces within a building from one main source of heat. It is a component of heating, ventilation, and air conditioning (short: HVAC) systems, which can both cool and warm interior spaces. A central heating system has a furnace that converts fuel or electricity to heat.

Anxious airline flyers may well remember 2024 as the year their worst fears about the safety of air travel felt confirmed, as a series of unprecedented, and in some cases fatal, airplane incidents ...
An aquastat is a device used in hydronic heating systems for controlling water temperature. [1] [2] To prevent the boiler from firing too frequently, aquastats have a high limit temperature and a low limit.
