How to use the App

​

Step 1: Finding the floor Area

All areas should be entered in metres

The area(s) in blue are positive values.  Area 1 should be the width and length of the total area you want to heat.

If the area you want to heat is an odd shape you should break up the area into squares / rectangles

If you need to add additional space please press the "Add" button

​

The areas in red are used to reduce the size of the heated area.

There are four different possible reductions.  Heating is not required under anything fixed to the floor.  Heating can be in a shower, however, careful planning is required, and heating cannot be installed when an acrylic or stainless steel shower based is used.  Please allow for heating under hanging vanities.

Leave the blue values as zero if they do not apply.

​

Press "Clear" to start again, or press "Next Step" to continue

​

Step 2: Finding the size of heating cable required for the area

The square metres of the area to be heated should already be displayed

The cable size (in Watts) should also be displayed.

The default setting is for a tiled floor.  If you want to install carpet or vinyl please press the "Carpet" button

Both the "Purchase Cables" and "Get More Info" buttons are linked to the Heatwell Website.

Press the button at the bottom if you want to get an idea on energy usage.

Step 3: Determining Energy Use

This section is indicative only, and will not be an exact measure of energy use

The Cable Watts has already been determined

Adjust the hours to how long you are likely to use the underfloor heating

Adjust the cost per kWh to reflect what your utilities power bill has indicated.  The cost needs to be in cents.​​
