THERMOR STEATIS

Heating, cooling and ventilation

The Thermor Steatis is an electric storage water heater for homes, made in France and offered in vertical wall mounted, horizontal and floor standing versions in sizes from about 50 to 300 litres. Its mark is the steatite heating element, a ceramic element housed in a dry sleeve inside the tank, which means less scale on the element and an element change without draining the heater. The tank is enamelled and protected by a magnesium anode, which places the Steatis in the middle of the Thermor range, below the Duralis with its hybrid protection.

We recognise this model across the auction sites and keep every one we see together.

On a used one

Ask for the year of manufacture on the rating plate and whether the magnesium anode has been checked or replaced, since a worn anode leaves the tank unprotected. Check for scale and weeping at the flange, test the thermostat and the element, and make sure the safety group is present and the tank has not been run without water.
