Undercarpet Heating

Warmtech’s undercarpet heaters use heating mats strategically placed wherever required. Positioned between the carpet and underlay, the heating mats are available in a range of shapes and sizes designed to fit most rooms. There’s no maintenance required, and no annual checkups are needed. With efficient zoning and a programmable thermostat, it’s easy to regulate your home’s temperature while saving energy and money.


The running costs are comparable to fan heaters and often are less than the cost of one coffee per week

These heating elements use 200 – 3000 watts, depending on the size of the room.

Electric underfloor heating provides more additional benefits than any other form of home heating. Used either as a primary heating source for whole house heating or as comfort heating to keep the chill off your cold floors, Warmtech has the electric underfloor heating system for you. Whether you are a contractor looking to install underfloor heating in a large development or a homeowner looking to install underfloor heating in a single room, Warmtech has the products and support to make your project run smoothly. With Warmtech, a complete installation can be achieved in hours without the need for specialist tools or skills.

Running Cost Calculator

PLEASE NOTE. This is intended as a guide only and is dependent on Ausgrid Energy prices. The above calculation is based @ 26¢/kwatt/hr. We have assumed that the heating is ‘ON’ for 6 hours a day (3 hours in the morning and 3 hours at night). Cost per month has been calculated @ 31 days per month. Every 1°C reduction in the temperature setting of your thermostat will result in a 5%-8% reduction in power usage and cost over 24 hours. The calculation of running costs can only be approximate. The actual cost will depend on a number of considerations – user preferences, temperature and switch-on time setpoints, cost of energy etc.


Undercarpet Heating

All of Warmtech’s undercarpet heaters are 100% water resistant.

Undercarpet Heating

The length of time it takes to warm the floor will depend upon the density of the carpet and the sub floor. As with undertile heating, an uninsulated concrete floor will take longer to heat up but will retain the heat for longer. Undercarpet heating will not provide you with an instant source of concentrated heat in the manner of a fireplace or bar heater. Rather the whole room is gradually warmed at the same time.

Undercarpet Heating

A typical installation will cost approximately 1.5** cents per hour per square meter of heated area when warming up. Once the floor has warmed up the thermostat switches the heater on and off automatically. In normal winter conditions if the heater is the only source of heat in a reasonably insulated room you can expect the heater to be on for between 30% and 50% of the time. This time will obviously vary depending upon the climatic conditions and the comfort levels required. Every 1ºC reduction in the temperature setting of your thermostat will result in a 6% reduction in power usage over 24 hours.

An average bathroom (500 watts) will cost approx $15 to $20 per month using an electronic floor thermostat at normal operating temperature.

** Please be aware that actual costs will vary between electricity supply companies.

Heat Controllers

Programming saves money because you do not unnecessarily heat your home when heating isn’t required, i.e. during the day while you’re at work. By lowering the heat during the day, you can realise significant savings: each 1ºC the temperature is lowered during an eight-hour period equals a savings of 2%.

Underfloor Heating

If your room is well insulated and complies with modern insulation levels as set out in the current building regulations you should be able to use Warmtech Underfloor Heating as the sole heat source.

Underfloor Heating

Warmtech has a range of specifically designed loose wire and matting heating systems for use under tile, natural stone and under carpet.

Underfloor Heating

No specialist skills are not required. The Warmtech system is designed so that any contractor, or competent do-it-yourselfer, can install it. The kit comes with a comprehensive installation manual should you need any assistance during installation.

A qualified electrician should always undertake the connection of the heater to the thermostat.

Underfloor Heating

Undertile Heating Systems:  The heater should not be made fully operational until such time as the tile or concrete installer has confirmed that the cement materials (i.e. adhesive & grout) are fully cured.  This may be anything from 1 – 3 weeks.  Turning the system on too early could lead to the cement drying out too quickly, creating an unstable subfloor.

Underlaminate Heating Systems: Once wired and tested, the system may be switched on immediately
