Details

There are two options:

  • Free Spooling Cable allows free hand laying and 100% coverage
  • DIY Mats for easier installation where the cable spacing is preset with a fixing mesh overlay

Approximate Size Calculation:

Calculate the "net" floor area to be heated (excluding fixed obstructions, vanity, toilet, shower etc)

  • net area  x 150watts/m

Note: For larger areas you can come off the walls by say 500mm and reduce the total wattage load and still cover the majority of the floor. But please contact us if you need clarification.

Example:

Net floor area to be heated @3m2 x 150watts = 450watts. If you fall between sizes, always drop down to the nearest cable size wattage.

Thermostats:

Please see the thermostat options below.

InsulAte Peel and Stick 3mm Mat:

InsulAte Mat increases the heating performance by 37%+ on concrete subfloors and reduces sound impact on wooden subfloors and it is so easy to install.

For concrete foundations, this is a "MUST" addition to greatly improve performance and operation costs. For wooden foundations it can replace slate and tile underlay.

Floor Primer should be used to prepare the floor for laying the heating cable.

Self Levelling Compound should be used to place a 4-5mm concrete cover the heating cable and total floor ready to be tiled over. This is optional depending on the tiler's requirements.

The above calculation is based @22 cents/klwt/hr. Assuming the heating is on for 6 hours per day (3 hours in the morning and 3 hours in the evening). Costs per month have been calculated on a 30 day month.

 

Every 1oC reduction in the temperature setting of your thermostat will results in a 5-8% reduction in power usage cost over 24 hours. The above calculation is approximate only and will vary depending on temperature set, operational hours and energy costs etc.
