The heating cable itself is only 2.3 to 2.7mm thick, however it is extremely strong with a lifespan of over one hundred years. This long life allows Warmfloor to offer up to 25 years warranty on its heating cable.
The cable itself runs at about 13.5 watts per metre which is a little warmer than the common worldwide standard of 11.5 watts. This small difference is to better suit New Zealand's unique climate zones.
