The undertile heating element, including the full earth braid and double insulation, is between 2.2 to 2.4mm thick.

Yes the undertile heaters are 100% water resistant.

The Warmtech undertile elements have been tested and approved by all the appropriate safety testing bodies. Each individual heater is thoroughly tested before it leaves the factory, again prior to installation and again during commissioning.
To comply with these safety standards all heaters must be used in conjunction with an RCD. RCD stands for Residual Current Device and is sometimes called an earth leakage breaker or earth leakage detector. RCD's are far more sensitive than fuses. They detect any slight loss in current and immediately shut off all power to the circuit before there is risk of shock.

As a rule of thumb, if your floor is acceptable for tiling, then it will be acceptable for heating. On particleboard or wooden subfloors we recommend using tile and slate underlay, hard or sharp articles should be removed and the floors should be completely free from dust, dirt and grease. Waterproofing, if required, is typically done after the heating has been installed but this may vary depending upon the local council requirements and installation details. If in doubt please contact your local representative.

The tiler should be the only person to walk on the floor once the heating elements have been installed. If you need to walk on the floor, you should do so only wearing socks or soft shoes.

The floor must be laid with either a flexible adhesive or a flexible additive. Your tiler or tile supplier will be able to advise you on the best type of adhesive for your installation.

This depends on the thickness of the tiles, whether the subfloor is concrete or wood, general levels of insulation and floor insulation. On an insulated wooden subfloor it takes approximately 20 to 40 minutes for the tiles to feel warm, then approx 45 to 90 minutes to heat the room. On an uninsulated concrete floor it will take longer. The floor will also take longer to cool down after the heater has been turned off.
On an insulated wooden subfloor, in a well-insulated room, the floor will be warm in 30 minutes. On an uninsulated concrete floor in a poorly insulated room, it could take 1 hour to heat the floor. The longer it takes to heat the floor, the longer the floor will retain the heat.

A typical installation will cost approximately 1.5** cents per hour per square meter of heated area when warming up. Once the floor has warmed up the thermostat switches the heater on and off automatically. In normal winter conditions if the heater is the only source of heat in a reasonably insulated room you can expect the heater to be on for between 30% and 50% of the time. This time will obviously vary depending upon the climatic conditions and the comfort levels required. Every 1ºC reduction in the temperature setting of your thermostat will result in a 6% reduction in power usage over 24 hours.
An average bathroom (500 watts) will cost approx $15 to $20 per month using an electronic floor thermostat at normal operating temperature.
** Please be aware that actual costs will vary between electricity supply companies.
