An Advanced Water Caleffi pressure and temperature relief valve is used to regulate and manage the pressure and temperature of hot water stored in a household storage cylinder and prevent the water from rising over 100C. The valve releases enough water when the preset criteria are met to allow the temperature or pressure to drop to within the working range of the system. It is suitable for use with unvented hot water systems as the valves were created.
