Valvola di sicurezza speciale per scaldasalviette

Special safety valve for towel rail

THE APPLICATION

Home comfort and electric towel rails

The domestic central heating and the heating and plumbing industries have, over the last few years, undergone developments from technical viewpoints, with electrical towel rails, as well as from design and style points of view. 
From simple radiators used for optimum heating in rooms, towel rails are increasingly seen as design objects.
The trend is now to make them features in the room without foregoing the actual function they serve, i.e., meeting design and installation needs while also guaranteeing energy savings and excellent mechanical performance. 

THE CUSTOMER

Our customer is one of the major manufacturers of home comfort solutions and specifically, fixed radiators and designer electric or hot-water towel rails.

DESCRIPTION OF THE PROBLEM

The Electric towel rails' operation

Towel rails contain a heating element that heats the fluid inside them - usually a mix of water and glycol. When the radiator reaches the set temperature, a thermostat will disconnect the heating element. There is a risk that electronics are not reliable and therefore, customers need the device to be fitted with a mechanical safety valve to guarantee that any excess pressure can be bled out in the event that the heating element fails to switch off at the set temperature.
