Pumps and pumping equipment are at the heart of any circulation system. They influence the efficiency of how other system components work, as well as having  a major influence on the overall performance of the system. Therefore when designing any wet system, it pays highly to focus on pump selection.

These can be pumps and pumping equipment for heating, domestic hot water, air conditioning, cooling, pressure boosting, water supply, rain water harvesting, irrigation and sewage / waste disposal to name but a few....

Heat exchangers are pieces of equipment built for efficient heat transfer from one medium to another. The media may be separated by a solid wall, so that they never mix, or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power plants, chemical plants, petrochemical plants, petroleum refineries, natural gas processing and sewage treatment.

Calorifiers and hot water storage cylinders are another popular arrangement where higher flow rates are required (although for limited periods) to heat water in a pressure vessel capable of withstanding a hydro-static pressure close to that of the incoming mains supply. (A pressure reducing valve is usually employed to limit the pressure to a safe level for the vessel)

DHW (Domestic hot water) calorifiers and cylinders are usually heated indirectly by primary water from the boiler / primary heat source, or by an electric immersion heater (often as a backup to the boiler). These vessels are also known as unvented cylinders and can be supplied with unvented kits where installed on a closed system.
