EChotwatt 70
The EChotwatt 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. 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.
EChotwatt ensures hot water in all taps and savings when circulation of the whole
pipe system is unnecessary.
