DEVIhotwatt™

DEVIhotwatt™ 45 (B), DEVIhotwatt™ 55 (B),
DEVIhotwatt™ 70 (B)

The DEVIhotwatt™ is a self-limiting heating cable that is used for temperature maintenance
of hot water supply and other fluids that need to maintain a certain temperature.

The self-limiting capability of the cable ensures that the output of the cable increase or
decrease according to ambient temperature.

DEVIhotwatt™ ensures hot water in all taps and savings when circulation of the whole pipe
system is unnecessary. All self-limiting heating cables must be over-temperature protected
by a thermostat, as the output will decrease, but never be zero, and be protected by a RCD
with a maximum trip current of 30 mA.

The cable is not approved for use in drinking water.

Benefits:

• Cut to length on site

• Black version is UV protected

• PVC free

Standard compliance:

• DIN VDE 0254: 1994-06
