UNDERFLOOR HEATING SUPPLIERS AND INSTALLERS
We supply three types of undertile systems, the first one is the loose wire system that we call a “cable kit”, the cable kit is simply a roll of cable on a drum and you have to mark the floor out and space it yourself on the floor.
The second is the 150w per m² cable mat which is normally used for internal rooms, the cable mat use’s exactly the same cable as the “kit” except the cable spacing has already been done for you, and therefore all you need to do is roll the mat out all over the floor until it’s used up.
The third one is the 200w per m² is normally used in external rooms such as conservatory’s, this is exactly the same cable as the 150w and the “kit” but the cable is spaced closer together to give of more heat.
The way undertile systems work is the closer together the cable is the more heat per m² will be generated with a minimum spacing of 60mm, at 60mm apart this equates to 200w per m², the 150w mat is spaced at about 80mm apart.
All cable mats are 500mm wide, to work out how long the mat will is, simply multiply the m² by 2, so if you have a 2m² mat, this means it will be 4 linear meters long, at 4 linear meters long, cut in half and folded back on itself would make it a 2m² mat.
All our cable systems incorporate a built in return which means you only have one end to connect, this is pretty standard these days but there are still some on the market at the cheaper end were you have to return the cable to the start to complete the circuit.
Also all our cables have an tinned earth copper braid that is encapsulated around the entire length of the cable, giving you maximum protect, how this works is if either the internal electric heater elements were to be damaged they would leak electric which would get carried to earth before it could escape because the tinned copper earth braid is wrapped completely around the elements, alternatively if the cable was pierced from the outside it means the object would be in contact with the earth braid and therefore no electric shock would occur. Not all cables have this style of protection, other systems just have a singular wire strand running through the centre of the cable which isn’t that effective, it’s good that there is form of earth but it doesn’t offer that much protection.
With the safety features mentioned above it means you can use these cables in wet areas like wet rooms and bathrooms in complete piece of mind.
Cable kits are brilliant for installations into small bathrooms or small kitchen area’s with awkward fixed objects to work around such as curved shower trays, toilets, kitchen units, kitchen islands.
As mentioned before the cable kit comes as one long continues roll of heating wire on a spool and you have to space the cable out evenly over the floor - this offers the installer complete freedom to space the cable evenly no matter how awkward the room shape.
If you’re installing the underfloor heating into a conservatory then we strongly recommend the 200w m² cable mat and 10mm tile backer boards.
If your unsure of how to work out what size kit you need simply times the length of the room by the width in meters e.g. 3m x 3.5m = 10.50m² minus 10% = 9.45sqm round it down to 9sqm and multiply by 150w = 1350 so you would need to choose a kit nearest to that figure a TPC1300 would be the one in this example.
The most important thing to remember is always select an under tile kit which is at least 10% smaller than the free floor area of the room because you cannot cut a cable down and having less cable is better in this situation.
Each under tile cable kit includes:
• DVCM-10 twin conductor, 3 mm thick heating element
• 7 Day timer digital thermostat and floor sensor
• Floor Primer
• Disposable roller for application of primer
• High adhesion fixing tape
• Lifetime guarantee certificate
• Full installation instructions
Under tile cable mats are the most popular choice for larger areas; the mats are available in two outputs, 150w per m² for internal rooms and 200w per m² for conservatories to compensate for the higher heat loss.
If you're installing the underfloor heating into a conservatory then we strongly recommend the 200w per m² and tile backer boards, 10mm is the most common size, but we do thicker boards is required.
If your unsure of how to work out what size mat you need to simply times the length of the room by the width e.g. 3m x 3.5m = 10.50sqm minus 10% = 9.45sqm round it down and TPCM1350 9sqm will fit in at 150w per m² or if it is a conservatory TPCM1800 9sqm.
The most important thing to remember is always select a cable mat which is at least 10% smaller than the free floor area of the room because you cannot cut a cable down and having less cable is better in this situation.

To give you an idea of running cost use the calculation below:
Take your floor area and multiply by the wattage of the cable mat, so if it’s a conservatory you would choose the higher output mat at 200w per m², in this example my floor space is 10m² x 200w = 2000w which is 2Kw (Kilo Watt) multiply 2Kw by the cost of your electric per Kw per hour which is on average 0.09p, 2Kw x 0.09p = 0.18p per hour until the system has reached your desired temperature, then the clever thermostat runs on about 40% of power thereafter to maintain your setting 0.18p x 40% = 0.072p per hour once it has warmed up, a typical day would work out at something like 0.54p based on 6 hours usage.
