What is a Thermostatic Mixer Valve?
A thermostatic mixer valve is an essential part of a well-designed
shower. Safe, convenient and economical, it ensures maximum
showering enjoyment while protecting you and your family from the
risk of scalding.
What is a thermostatic shower mixer?
A thermostatic mixer maintains an exact water temperature for the
duration of your shower. It protects you from any sudden changes in
the water supply to the shower, so even if somebody flushes the
toilet or turns on the kitchen faucet the temperature of your
shower will remain the same.
How does a thermostatic mixer work?
The thermostatic valve mixes the hot and cold water to your
pre-selected temperature and reacts instantly to any changes in the
pressure or temperature of the water supply by re-adjusting the mix
of hot and cold water. Should there be a failure in your cold water
supply, the thermostatic valve will automatically shut down.

Do I need one?
