EHM - Heater Mats

Underfloor heating mats - ceramic/stone floor

Application

EHM heater mats are used under ceramic or stone floors.  They consist of a small diameter heating cable attached to a nylon web, which can be fitted into the tile adhesive.  In poorly insulated properties supplementary heating may be required.

For peace of mind in rooms with exceptionally high heat loss, such as conservatories, select from our High Density (200 watts per square metre) range.

Features

• Mats covered by 10 year warranty
• 4mm cable diameter minimises increase in floor height
• Pre-assembly on to nylon web ensures even heat distribution and keeps installation time to a minimum
• The nylon web can be cut to suit the shape of the area
• 3m long cold lead
• Choice of thermostats (must be ordered separately)
• Choice of Standard Density (160 watts per square metre) and High Density (200 watts per square metre)

Selection

Calculate the area of floor to be heated.  This will be the total floor area minus the area occupied by fixtures such as cupboards, sinks, baths etc.  Refer to the schedule of EHM mats to find the mat with a square area slightly lower than your calculated figure.  This is likely to be the mat for you.  For larger areas a combination of mats will be required. 

To double-check your selection, draw a sketch of the free area.  Leaving a space of 30mm between mat runs and 80mm between the mats and the wall, draw the mat runs onto your sketch.  You can cut the nylon web at any point along its length but you cannot alter its width.

If you are unsure whether there is quite enough space to install a particular EHM mat you should consider using a slightly smaller mat.  Remember although you can cut the web at any point you must not cut the heating cable.

Choice of Thermostat

Select from four thermostats

A16C Manual thermostat providing selection of air and floor sensor or floor sensor only

G16C Programmable digital thermostat with air and floor sensor

F16C Programmable digital thermostat with floor sensor only (generally used for bathrooms)

T13C W Programmable touch screen (white surround) providing selection of air and floor sensor or floor sensor only

T13C S Programmable touch screen (silver surround) providing selection of air and floor sensor or floor sensor only

Insulation

To prevent downward heat loss, we recommend that EHM mats are installed onto F-Board insulation. 

F-Board is low-profile insulated tile backer board.

Application

F-Board Tile Backer Boards should be used wiith BN Thermic ECK & EHM electric underfloor heating systems.  Installed directly on to the sub-floor and immediately beneath the tiles themselves, they provide exceptional thermal insulation with a minimal increase in floor height.

The boards can be installed onto wooden or concrete sub-floors and will significantly reduce the running costs of an underfloor heating system.

Selection

F-Board-6 (6mm thick)

Provides an extremely effective insulation barrier where build-up must be kept to a minimum.

F-Board-10 (10mm thick)

As the effectiveness of insulation increases with thickness, F-Board-10 should be selected where maximum economy is required and the additional floor build-up is acceptable.

Features

• Full resistance to moisture absorption
• Unique combination of low profile, strength and thermal efficiency
• Lightweight and easily cut to shape
• Easily fixed in place using standard tile adhesive
