A Calorifier is an industry term for a storage vessel that has the capacity to generate heat within a mass of stored water.
Generation of heat is commonly provided by an indirect heat source via a heat transfer coil or heat tube battery. Historically, Calorifiers have tended to be designed around the capacity of daily water demand, with a low heat input coil that would re-generate the hot water supply during non- peak usage periods. However, recent manufacturing techniques and material quality mean the coil output is able to recover quickly to re-generate much larger quantities of hot water. Heat exchange 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, dedicated hot water boiler, or in some cases a renewable energy source.
Calorifiers may be installed onto an open vented system, with cold water supplied from a storage tank which provides the head pressure for the hot water system.
