Under tile heating can augment your existing heating or be a total solution

Many homeowners believe that under-floor heating is not necessary when they are installing other home heating solutions.  This is simply not the case - whilst under-tile heating can be used to heat a room, it can also be used to simply heat the floor.  Have you ever been in a traditionally heated tiled room?  The room feels warm at head hight, but the floor is cold and it is not comfortable walking in bare feet.  Under-floor heating can be your entire heating solution, or it can simply augment your other heating systems.   

Did you know that ducted heating can cause a temperature difference of up to 12 degrees between the floor and ceiling?   Under Tile Heating heats uniformly form the floor to ceiling and will also save you hundreds of dollars in the long run compared to bathroom heat lamps.  As a total bathroom heating solution its running costs compare very favourably to other heating solutions such as heat lamps - see below.

HOTWIRE Under-Tile Heating is the most flexible system available

Unlike many other under floor heating products that are expensive to buy, install, run and maintain, the HOTWIRE Under Tile Heating DIY kit enables you to do most of the work yourself and will only need the service of an electrician to connect the controller to the power once the hotwire has been laid. The flexibility of using a coiled wire verse a conventional heated mat makes installation so much easier, especially when laying in small tricky spaces around toilets and doorways. The heated HOTWIRE coil can simply be laid down on your homes substrate and taped in a coiled design before laying tiles on top. Therefore, your room will be warmed evenly leaving no cold spots to freeze your toes.  Watch the instructional video below to see why Hotwire under tile heating is the most versatile on the market.

How to measure your floor?

The length of your HOTWIRE Under Tile Heating coil is based on the square meter-age of space that you would like to cover. Generally, this doesn't include the area under fixed units such as vanities, cupboards, baths etc. 

Once the square meter-age of the room or space you want to heat has been determined, select the corresponding range in the product options section and your price will be calculated.

For example say your bathroom is 4 square meters but with a permanently fixed vanity and shower, only 3 square meters of tiling will be pulled up. You will select the 2.60 - 3.30 range from the product options drop down box. The calculated price includes all of the installation hardware within the kit as well as the touch screen thermostat.
