Solar Thermostatic Mixing Valves (TMV)

Solar Thermostatic Mixing Valves

Storing energy from the sun in the form of hot water, can lead to water arriving at the taps at higher than normal temperatures. In some cases, the cylinder maximum store temperature can be raised to as high as 80°C, which if delivered through a tap or any outlet, would present a severe danger of scalding.

The Solar Thermostatic Mixing Valve (TMV) is designed to reduce the water temperature to a safer level. Unlike the under basin or bath/shower type valves we are familiar with, the Solar TMV is designed to function continuously at high temperatures, something a standard TMV2 valve cannot cope with.

Fitted close to the HW outlet from the cylinder, the Solar TMV blends the high temperature hot water with cold, to provide safe water supplies. Flow rates are also greater on these valves and are suitable for use on pressurised systems (although they may not be suitable for use on some Low Pressure (LP) gravity Domestic Hot Water Systems (DHWS)).

Most importantly, Solar TMV should not be installed instead of TMV2 or TMV3 valves, as they are used in a different context to these valves.

Available in 22mm, 28mm and 22mm Low Pressure options
