Thermostatic mixing valve
Water safety in buildings, published by the World Health Organization in 2011, defines thermostatic mixing valves as: ‘Tempering valves that are typically temperature-activated. Used to mix hot and cold water to achieve a predetermined outlet temperature, and that are fitted between the water heater and the point of use to control the distribution temperature. Slightly different temperature ranges are used in some countries.’
Legionnaires' Disease - Operation and Maintenance Log Book (BG 58/2015), written by Reginald Brown and Salim Deramchi, and published by BSRIA in May 2015, defines a thermostatic mixing valve as a: ‘Mixing valve in which the temperature of the water at the outlet is pre-selected and automatically controlled by the valve.’
