Comfort HW | self-regulating cable for water heating

Comfort HW is a self-regulating heating cable designed to compensate for the heat losses from hot water distribution systems.

General details

Comfort HW is a self-regulating heating cable designed to compensate for the heat losses from hot water distribution systems. When hot taps are infrequently used, the water residing in the distribution pipework cools and is usually run to waste before hot water from the storage cylinder arrives at the tap. Its power output self-regulates in response to the pipe temperature. By installing Comfort HW to the pipework (beneath the thermal insulation), heat losses are eliminated, and the water is maintained at the required temperature (45-70 °C).

Installation: Comfort HW is quick and simple to install. The cable can be cut to match the exact length of the pipework. Termination, splicing and power connection components are all provided in convenient kits.
