Installation

Tiled Floor

The EHC heating cable should be installed in a flexible self-leveling compound or directly into the tile adhesive. It is important that the heating cable is completely covered.

Other Floor Surfaces (carpet, vinyl, engineered wood and laminate floor)

The EHC heating cable should be completely covered in a flexible self-leveling compound with the required floor surface applied once the compound is completely dry. Great care must be taken to ensure that fixing devices are not driven through the heating cable.
Where underlay is required, the lowest tog option is recommended. If there is any doubt about the suitability of any given floor surface for use with underfloor heating, confirmation should be sought from the flooring supplier.

Selection

The objective is generally to cover as high a percentage of the free floor area as possible. The free floor area is defined as the floor area not occupied by permanent fixtures such as kitchen cabinets and shower trays. Use the table provided to select the correct cable.

Large Rooms

For large rooms it is common practice to use more than one heating cable. In these circumstances there is a choice of subdividing the room into separate zones each controlled by its own thermostat or connecting the heating cables together electrically in parallel and using a single thermostat. When controlling more than one heating cable from a single thermostat it may be necessary to incorporate a contactor into the control circuit.

Control

Thermostatic control must be used. BN Thermic offers a range of thermostats all of which are supplied with a floor probe. The thermostats can be configured for primary control via the built-in air sensor or via the floor sensor. When using more than one heating cable, check that the combined load of the heating cables is within the switching capacity of the selected thermostat. When the combined load is greater than the switching capacity of the selected thermostat an appropriately rated contactor must be selected.

A16C

Simplicity is the key. The A16C has a smart uncluttered appearance with a dial for temperature adjustment and an on/off switch. Capable of switching loads up to 3.4kW, the A16C is configurable for ‘air and floor sensor’ or ‘floor sensor only’

U16C

The U16C offers simple 7-day programming with programming buttons hidden behind hinged doors on the thermostat face. Capable of switching loads up to 3.4kW, the U16C is configurable for ‘air and floor sensor’ or ‘floor sensor only’. Features include a backlit screen and a summer switch allowing the heating to be switched off without losing the programme.

T16C

Our latest full colour touch screen thermostats can switch loads of up to 3.6kW and provide ultra-simple 7-day programming.  Available with a choice of white or silver surrounds, the T16C can be configured for ‘air and floor’ or ‘floor only’ control.  When required, the air temperature can be controlled via an IP65 rated remote mounted wall-sensor (T16R).  This arrangement is particularly well suited for bathroom applications. The T16C also allows the user to monitor energy usage and running costs.

F-Board Insulation

To limit downward heat loss and to significantly improve the economy of an underfloor heating system, the use of F-Board insulated tile backer boards is highly recommended. Installed directly onto the sub-floor and below the heating cable, they provide exceptional thermal insulation with minimal increase in floor height. F-Board insulated tile backer boards are generally held in place using standard tile adhesive.

Selection

Each F-Board covers 0.72m² and sufficient boards should be selected to completely cover the floor area. Total floor area (m²) ÷ 0.72 = minimum number of boards required

F-Board-6

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

F-Board-10

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

Features

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

Technical Specification

Accessories

Floorprep Primer

Suppresses dust and improves adhesion on a variety of sub-floor types including
concrete and plywood. One bottle of Floorprep Primer covers approximately 6m² when
diluted 1:1.

Floorprep is easily applied using a Floorroll Roller.

Not required when using F-Board insulated tile backer board

EHM-R Kit - Cable Repair Kit (for emergency use only)

For use when a heating cable has been cut usually during installation or by drilling through the floor.
