Choosing a size

Measure the free floor area in your room and order a system that covers 80-85% of that area. Awkward shaped room with fixtures should aim for 80% coverage. The heating cable within the mat cannot be cut short, so don’t order a mat larger than you need.

Suitable insulation is essential to reduce running costs and to reduce warm up time. Once you add the required underfloor heating kit to your cart you will be given the option to purchase the appropriate insulation.

Heating large areas or multiple rooms

It is not advised to use one underfloor heating kit for multiple rooms. It is important that each room has its own mat and thermostat for easy control of the system. 

Open plan rooms can be on a single thermostat as long as the area of matting is less than 22m².  For areas bigger than 22m² please order multiple systems.

 If a room has 2 different final floor coverings then 2 separate systems with individual thermostats should be used.

Our range of thermostats

Touchpad Programmable Thermostat - An attractive, modern digital thermostat which is programmable.

Freedom Wi-Fi Thermostat  Similar to our standard touchpad thermostat but with the ability to controlled with your smartphone. Can be controlled by Alexa or Google assistant.

How much does it cost to run?

Consider an average room size of 10m2. The heated area is approximately 80%, or 8m.

In the case of the 150W mats, when the heater is ON, the hourly consumption is 150W times 8m, or 1200 Watts per hour.

A properly insulated room, controlled by the recommended energy efficient thermostats, will operate at a duty cycle of 25% to 50% (meaning 25% to 50% of the time the heater will be ON, and the rest of the time OFF).
In this circumstance the average electricity consumption for heating the room will be 300 - 600 Watts per hour.

The actual hourly cost depends on your local electricity rates.

Should I use insulation?

We strongly advise to the use of Insomax insulation when installing the electric underfloor heating system. By using insulation you will reduce running costs and the warm-up time of the floor. 

What is Insomax Insulation?

Insomax insulation board has been developed for use with Rayotecs' electric underfloor heating mats under tiles and any floor covering being laid on top of a latex based self-levelling compound.

Insomax insulation boards are made up of extruded polystyrene foam, produced environmentally friendly, without the use of CFC or HCFC blowing agents, have zero Ozone Depletion Potential (ODP) and are fully recyclable.

Insomax insulation boards have high thermal insulation properties, high compressive strength (30 tonnes per m2) capable of supporting long term static loading, waterproof, rot resistant, light weight/easy to handle, easily cut with a sharp knife and available in a variety of depths (Please contact the office for depth requirements of over 50mm).

For installation on wooden suspended floor then our Ultrabacker should be used as it can be screwed down as well as bonded.

Is it safe to use in Wet areas?

Yes, the cables are earthed.

How easy is it to install?

The cable electric underfloor heating mats are extremely easy to install.

Under tiles, the installer simply lays the cable electric underfloor heating mat directly between the sub floor/insulation and tiles. The same flexible tile adhesive used for fixing the tiles is used for bonding the Insomax insulation onto the subfloor.

The laying of the insulation and mats can be done easily by any consumer. Due to the web like mesh, in most cases a primer will also not be required- only a little amount of cloth tape is needed to fix the mats down.

A qualified electrician must complete the connection between the heating mats and the electrical circuit.

How do I know which size mat to order?

Measure the available exposed floor space in your room. It is advised that you purchase a system which allows 80-85% coverage. For example, if your room measures 15m, you would purchase the 12mMat. If a room is of an awkward shape with many fixtures in the centre of the room, it is advised that you purchase a system that allows approximately 80% coverage.

What if my room is larger than your largest available mat?

Several mats can be connected in parallel to a junction box. Please remember that the thermostats allow a maximum of 16 amps, therefore the maximum on one circuit is approximately 22m2. If the heated area is larger than 22m2 then several kits should be purchased to avoid overloading the thermostat.

Can I cut the mats?

You can cut the mesh but not the heating cable.

What is the thickness of the cable?

The cable is 4mm thick.

What is the working temperature of the cables?

The cables work at approximately 30-40 ºC

How long is the cold lead of the mat?

The cold lead is 3m in length.

Can I lay the mats under permanent fixtures?

No - the mats can only be located in the available free space. There must be some form of air gap between any furniture and the floor, so the heat may escape.

Does it provide a primary heat source?

In most cases in a new build / well insulated property, the system can provide primary heating. In cases where homes have single glazing, vaulted ceilings, poor insulation levels or less than 80-90% cable heating mat coverage, the system may need a source of back up.

What kind of floor coverings can I use and do I have any limitations?

Covering Thickness/ Tog
Carpet Underlay
Total 2.5 Tog or less
Tile 5mm - 30mm
Wood 12mm or less
No limitations stated, all are standard thin materials.

What if I damage part of the cable?

It is best to replace the mat. It is not ideal however accidents do happen, try wear soft shoes when working with electric UFH and keep sharp objects away during the installation procedure!

How safe are the mats?

The mats are manufactured and tested in full conformity with IEC (International Electrotechnical Commission) Global Quality Standards. The continuous foil-coated screening jacket ensures 100% guarantee of electrical safety and absence if electromagnetic radiation.

What is the warranty of this system?

The heating mats come with a 16 year manufacturers warranty.
