Should I use insulation?

We strongly advise to the use of Insomax insulation when installing the electric underfloor heating system. By using insulation you can reduce warm-up time of the floor. This will provide you with a greater level of comfort and result in reduction of electricity cost.

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 kit 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 15m2 , you would purchase the 12 - 13.8m2 kit.

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

Contact us if you require a larger system

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 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 cables come with a 16 year manufacturers warranty.
