Cylinder Thermostat

A temperature sensing device used to control the temperature of the stored hot water within the cylinder whenever the hot water circuit is timed to be on.

Cylinder Thermostats should be installed in accordance with the manufacturer’s fitting instructions and comply with the appropriate regulations.
 
They should be fitted between a quarter and a third of the way up the cylinder unless otherwise directed by the manufacturer. It is important to have a good, clean contact with the metal cylinder wall when fitting a strap-on thermostat.
 
The recommended temperature for storage of domestic hot water is between 60oC and 65oC, being high enough to kill off the harmful bacteria in the water, yet low enough to deter the production of scale.
 
Since storage cylinders are quite likely to be located within a cupboard, it is important to make the Cylinder Thermostat as accessible as possible. Certain models have a means of making adjustment of the temperature setting difficult to prying fingers.
