Calorifiers

Calorifiers are apparatus used for the transfer of heat to water in a vessel using an indirect means. The source of heat is usually obtained in a coil or pipe that is immersed in the water. The heating instrument uses the principle of thermodynamics whereby the water is heated above its temperature to be used for different purposes. A calorifier is an industry term for a storage vessel that has the capacity to generate heat within a mass of stored water.

Calorifiers can be installed onto an open vented system with cold water supplied from storage tanks which provide the head pressure for the hot water system. The most commonly used and seen are in commercial applications such as an unvested system with cold water is supplied directly from main pressure and in some cases, through a pressure booster set. There are many calorifers available with the option of an additional heat output coil that is heated from a renewable energy source such as solar thermal.

The heat exchanger of calorifiers is a device built for efficient heat transfer from one fluid to another whether the fluids are separated by a solid wall and this is to make sure that they never mix or the fluids are directly contacted. Calorifiers are widely used in petroleum refineries, petrochemical plants, chemical plants, refrigeration, natural gas processing, space heating, air conditioning and power plants.

Typically, the existing building calorifier room and in the existing system, calorifiers can transfer heat from a circuit that contains high temperature and pressure water that is generated by the boilers to a separate circuit and is run at a pressure and temperature that is safe to distribute within the building concerned.

In the generation of heat, it is commonly provided by an indirect heat source via a heat transfer coil or heat tube battery. Historically, calorifiers are designed around the capacity of daily water demand with a low heat input coil that would regenerate the hot water supply during the non-peak usage periods.

However, the recent manufacturing techniques and material quality mean the coil output is able to recover quickly to regenerate much larger quantities of hot water. The heat exchangers takes place at the primary coil and is usually supplied via a primary hot water flow through a controlling zone valve from a main central heating boiler that is dedicated hot water boiler or a renewable energy source.
