Underfloor Heating Design
About us.

As an established specialist supplier of electric underfloor heating with over 10 years experience we can offer genuine advice regarding a wide range of heating sytems to suit all floor types. We provide underfloor heating solutions for wooden floors right through to the more powerful heating systems to suit tile floors.

Floor Heating Solutions is a trading name of Ambient Electrical Ltd, supplying premium quality underfloor heating systems on-line since 2002

Our Products - we supply premium quality systems, all heating cables & mats use dual core technology and fluoropolymer (teflon) insulation for reliability and longevity - all are 100% earth screened.

All heating cables and mats are CE marked and meet or exceed international standards set by Intertek SEMKO, IEN/EN 60335.

Heat Density

With adequate insulation under tile heating cables and mats designed to 150w/m² will provide a full heating solution for most areas of the home.

The higher output 200w/m2 systems can be used to reduce heat up times in all areas (except where timber sub floors are fitted) and are recommended for providing underfloor heating for conservatories and other areas of high heat loss.

Heating cables and mats designed to 100w/m² will provide sufficient output for tile warming and secondary heating.

    electric underfloor heating with wooden floor
    All underfloor heating systems require adequate insulation either beneath the screed or directly beneath the floor heating mats or cables.

    Assuming that the correct underfloor heating insulation is fitted below the screed, our under tile heating cables or under tile heating kits can be installed directly onto the screed and then tiled or embedded within a two part latex levelling compound. If you are unsure of existing insulative properties, it would be recommended to fit an insulated tile backing board prior to installation of the heating system. Minimum required insulation thickness is 6mm. We recommend Marmox® or Blueboard insulation boards for this purpose.

    Tiled floor finish on concrete or screed base

    All solid floors whether concrete, screed or asphelt require some form of insulation beneath then or preferably above in the form of an insulated backing board prior to installation of your electric underfloor heating. Heating mats or cables are attached directly to the insulated screed or insulated tile backing board prior to tiling directly over with a flexible floor tile adhesive. Design will vary from 100w/m² to 200w/m² dependent on floor base specification and heating requirments. If you are unsure please contact us to discuss.

    Tiled floor finish on to timber / plywood base

    All timber floors whether floor boards, chipboard or plywood must be assessed to confirm structural integrity and suitability for tiling prior to installation of electric underfloor heating. Floor boards will always require provision of insulated tile backing boards before heating can be installed. Mats and cables can be fitted directly on to ply-wood and moisture proof chipboard, providing that the floor is treated with a suitable priming solution. Design will vary from 100w/m² to 150w/m² dependent on floor base specification. If you are unsure of this, please contact us to discuss.

    As a general rule for both of the above scenarios, under tile cables offer a far more flexible heating solution in terms of area coverage and heat output. Under tile mats provide a quick solution for areas of a regular shape.

    All underfloor heating installations must be connected via an RCD (earth trip) protected circuit. All underfloor heating applications in bathrooms, wet rooms and shower rooms must use heating cables with an earth screen.

    Cables / mats with twin conductors are considered easier to install than single wire alternatives.

    In screed cables.

    In screed systems provide a highly efficient electric underfloor heating solution for new builds or areas where a new floor is being fitted. Heating cables are installed directly above foil faced insulation below a 65mm screed. Design parameters require output of between 130w/m² and 200w/m² dependent upon room / construction type.

    Laminate / Wood Floors underfloor heating

    Laminate and engineered wood flooring can provide a highly effective heating medium with ThermoLAM or Carbon Heating film heating systems. Use with 5mm or 10mm XPS SR insulation directly beneath the heating foil. Systems of varying outputs and sizes can be selected to provide full or secondary heating for most areas of your house. Carbon film heating systems are not suitable for use in bathrooms as they do not employ the required earth screen.

    Underfloor Heating beneath Vinyl, Amtico & Karndean floor coverings

    Heating beneath Vinyl will require special consideration due to the maximum floor temperature limits permissible and the need to provide a solid surface on which to bond the flooring. The subfloor must be well insulated beneath the screed or by using a reinforced insulated tile backing board such as Marmox. Heating cables (TPP)are then attached to the surface prior to applying two applications of a suitable fibre reinforced floor smoothing compound. The first application (5mm) is to embed the heating cables, followed by a second layer (3mm) to put distance between the heating cables and the vinyl to allow heat to dissipate across the floor. Maximum floor temperature not to exceed 27degree C.

    Carpets with underfloor heating

    Heating beneath Carpet will require special consideration Carpet effectively creates a thernal block above the heating. The subfloor must be well insulated beneath the screed or by using a reinforced insulated tile backing board such as Marmox. Heating cables (TPP) are then attached to the surface prior to applying two applications of a suitable fibre reinforced floor smoothing compound. The first application (5mm) is to embed the heating cables, followed by a second layer (3mm)to put distance between the heating cables and the Carpet Underlay (underlay must be of the low tog type) to allow heat to dissipate across the floor. Maximum floor temperature not to exceed 27degree C.
