Electric Under Floor Heating

Large Range of Systems

Floor Heat Australia offers a large range of floor heating systems to suit different applications and different end user needs.

In Slab

In slab heating consists of heating cable that is fixed to the slab reinforcement, typically to the top layer of reinforcement, prior to the slab being poured. The heating cables heat up the slab, which in turn heats up the floor covering above. This system is designed for connection to 'Off Peak' or 'Time of Use"'tariff electricity supply with the concrete slab 'storing' the heat during the evening (i.e. the 'recharge' period) and emitting this heat steadily during the day.

In Screed

In screed heating consists of heating cable fixed on top of the floor structure using a light steel mesh or fixing strips. The cables are covered with a sand/cement screed bed, typically 25mm in thickness with a minimum thickness of 15mm. The cables heat up the surrounding screed, which in turn heats up the floor covering above. in screed heating is considered to be a 'direct' acting system although it does have some storage characteristics.

Under Tile (devimat)

Under Tile heating consists of a thin heating cable pre-laid on a self adhesive fibreglass mesh. Devimats can be covered with a flexible tile adhesive making them ideal for new construction or renovations where minimising floor height loss is important.

Alternatively, a self levelling compound may be used, for instance when used in an under carpet application. In this case, the levelling bed needs to be at least 12mm thick to provide a thermal mass and to provide some protection from the nails in a smooth edge. The devimat cable heats up the surrounding glue bed or levelling bed, which in turn heats up the floor covering above and radiates heat into the room.

Under Floating Timber (devicell)

Devicell is specifically designed for heating floating timber floors. The system consists of a heating cable that is fixed to an insulated panel that is specifically designed to spread the cable out at 100mm centres. The panel's polystyrene insulation ensures that the heat loss downwards is minimised and its aluminium surface ensures a uniform distribution of heat transfer to the floating timber floor.

Under Battened Timber

There are two types of under battened timber heating. The first is where the timber is laid over a concrete slab. In this system, cables are installed on the concrete slab, preferably over faced insulation with a air gap to the battened timber floor. The cables heat up the air cavity, which in turn heats up the timber floor covering above and radiates heat into the room.

The second is where the where the timber is supported by joists. In this system, the heating cables are installed on a light steel mesh (chicken wire), which are fastened to the joists. The heating cables are positioned approximately 30mm below the floor boards, with faced insulation installed directly below the cables. The cables heat up the air cavity, which in turn heats up the timber floor covering above and radiates heat into the room. The insulation helps minimise downward heat losses
