Small high heat loss rooms

Rooms with small floor areas have a greater proportion of wall to each m² of floor area, leading to a far higher heat loss per m² of floor than larger rooms. 240W Mats are designed to overcome this high heat loss by offering the maximum output in the restricted floor area, and still benefit from being laid onto insulation boards where possible.

General high heat loss rooms

Rooms with a higher than average heat loss benefit from the fast warm-up time and high output of the 240W system - this includes rooms such as garden rooms, conservatories, foyers and entrance halls with high air movement, or rooms where insulation boards cannot be installed on top of the screed bed.

Heating a proportion of the floor

In some situations only a proportion of the floor can be heated, such as kitchens and bathrooms. In these cases the 240W mats ensure enough warmth is still provided to heat the entire room. In very large structures, such as churches or barns, the 240W mats can provide targeted heat in the areas where it is required e.g. between pews or specific areas where people will be sitting/standing.

Floor drying

The 240W system offers fast floor drying which can be desirable for safety reasons around swimming pools or in wet rooms. In wet rooms and bathrooms the system can speedily heat the floor and walls to dry out tiles to help prevent mould, and in hotels to prepare bathrooms for the next guest.

Selecting the correct sized heating mats

To start with you will need to calculate the free floor area (FFA). To calculate the FFA you should measure the room to find out the total floor area. You should then subtract from this any areas where kitchen or bathroom furniture will be placed, or where furniture without an air gap beneath it will be positioned. Once you have taken off these areas you have your FFA. Our recommendation is to deduct 10% for fitting space in rooms up to 15m², 7% for rooms between 16m²—25m² and 5% fitting space for larger rooms.

Floor coverings and sub-floor surfaces

 The 240W mat system must only be used beneath tile, stone and cementaceous floor covering as the heat must be able to rapidly dissipate into the room. For the same reason it is vital that no thermal blocks (including rugs, mats or furniture) are placed on top of the heated area of the floor. The mats must be installed onto a cementaceous layer e.g. Heat Mat’s concrete faced thermal insulation boards, concrete, tiles, or a 2mm layer of tile adhesive skimmed over wooden sub-floors.

Energy Efficient Solution

240W heating mats are almost 100% efficient at converting electricity into heat and they can easily be powered by locally generated electricity from either photo voltaic or wind power sources. When used with Heat Mat’s intelligent NGT controllers, these 240W mats are Heat Mat’s most energy efficient heating mat system, and a Part L compliant heating solution.

Approved and guaranteed

We manufacture our high-quality heating mats and cables in Denmark and Germany. Our electric underfloor heating mats are supplied with a Lifetime Warranty and independently BEAB approved.

Innovative heating cable technology

Over the last three decades Heat Mat have worked to continuously improve the design of their cables and mats to ensure their safety and longevity. This unique combination of technologies means you get a safe and fast to install system without sacrificing quality. Only Heat Mat’s systems include this combination of technologies:

• Litzer Wire Technology – multiple heating elements are spun together to provide superior strength in a very flexible heating wire
• 200°C Fluoropolymer Protection – super-high temperature fluoropolymer insulation surrounds the heating elements and provides superior protection against overheating and physical damage
• Kevlar Anti-stretch Cable – Kevlar strands run through the centre of the heating cable preventing it from being stretched and damaged during installation
• 100% Earth Shield – an aluminium safety shield wraps the entire heating cable to ensure the system is instantly shut down if damaged. The shield also enables the cables to hold their shape when being installed
• Anti-crush Cable Jacket – the high quality PVC cable jacket provides unrivalled protection against crushing and cutting damage during installation
• 100% Shielded Coldtail – the entire coldtail is shielded continuing the 100% electrical protection seen on our heating cable
• Cut & Turn Mat System – the cut-and-turn systems allows mats to be turned back on themselves multiple times during fitting, meaning less mats are required ensuring a far smoother installation
• Zero-float Mesh – the mesh terminates at the last row of tape rather than continuing to the ends of the cable, so none floats up when covered in levelling compound or screed
