Under tile heating mats
If you are planning to renovate an existing floor, QuickNet floor heating mats are the most economical, luxurious and practical form of space heating you can buy.
During renovation, electric heating mats are rolled into position prior to the screed being laid. These mats heat the floor during regulated heating periods.
How to install
Unlike traditional heating systems there are no ducts, fans, consoles or vents required. This frees up your wall and floor space giving you the freedom to decorate your interior without interferences.
Discuss it at your initial planning stage with your architect, builder or specialist heating installer.
Measure your heating area
Using the examples below, measure the floor area you need to heat.
Note: do not calculate permanent fixtures (wardrobes and benches) as heating areas.
Living room example A
Heating area = 4.1m x 5.1m
Bedroom example B
Room area = 2.1m x 4.1m
Area of fixtures = 2m²
Heating area = 8.6m² - 2.0m²
Bathroom, toilet, laundry
Room area = 2.0m x 3.75m
Area of fixtures = 2.2m²
(bath, shower, toilet, bench)
Heating area = 7.5m² - 2.2m²
Which heating mat size do I need?
After measuring your desired heating area, refer to the table to locate your suitable product (unit).
Most types of floor coverings can be used, for example carpets (wool or synthetic), vinyl tiles, ceramic tiles and slate.
Bitumen backed carpet tiles are not suitable.
Cork tile and parquetry must be laid on a dry floor. In other words, this must be laid after initial use of the heating system to evaporate the moisture remaining in the concrete floor.
Depending on the type of tile, a waterproof adhesive (such as a two-part latex adhesive) or mortar-bed fixing system must be used. Some adhesives (particularly the water based latex adhesives) will deteriorate and soften at temperatures above 40°C. The adhesive chosen should be capable of withstanding temperatures of up to 60°C without a loss of bond strength.

Gentle background warmth
The heat stored inside the floor is emitted from the whole surface area, giving an almost even air temperature from floor to ceiling. Warmth is produced where it is required most, underfoot, and then radiates throughout the area.
CSIRO tests show that where floor level temperatures are around 16°C people feel comfortably warm all over. When floor level temperatures are lower, people feel cold even if the temperature at head level is over 21°C.
nVent Raychem T2 QuickNet floor heating is the energy - efficient way to provide a constantly comfortable room temperature.
Health and safety
The system is free from dirt, smoke or fumes. Any dust movement is minimal, so the system is ideal for people who suffer from respiratory difficulties such as asthma.
The system is safe for all family members as there are no burning surfaces
Some other heating systems present hazards for children, the elderly or pets
The system is securely encased in the floor and operates in silence
Economical and Energy efficient
Heat input to the floor is controlled by wall-mounted or in floor thermostats. Heating in each room or zone is controlled by a separate thermostat, so energy need never be wasted.
The system takes advantage of low-cost off-peak electricity or time of use tariff available in most areas. When normal rate electricity is being used the system can be regulated by a time clock. Check with your local electricity authority regarding off-peak power availability in your area.
The floor stores enough heat during the off-peak charge period to maintain a comfortable temperature for the full 24 hours. Heat storage is topped up again during the next heating period.

What happens if something isn’t working – Can it be repaired?
In the unlikely event of the heating element being damaged, it is a straight forward job to locate and repair the fault. We have equipment that can locate the cable and it’s fault. It is a simple matter of exposing the cable and fixing the repair.
Are there any additional hidden costs?
Costs not covered are:
Wiring from the thermostat and heating unit to the switch board and connection to the off-peak supply. This work is usually done by the onsite electrician when all other lights and power points are wired.
What is the guarantee?
The standard warranty of 10 years from the date of purchase applies to all T2 Quicknet heating mats manufactured by Raychem. Thermostats are covered by a 2year warranty from the manufacture.
What maintenance is required?
Over the lifespan of the Raychem T2 QuickNet, minimal maintenance is required as there are no moving parts that wear and tear, apart from the thermostat which is a simple and easy replacement.
Do you need to alter home/building design or make concrete slab thicker to accommodate heating cables?
No. The T2 QuickNet heating mats are laid and glued directly on top the existing floor. Also, there is no need to allow space for ducting or furnace.
What is the minimum heated area in a existing floor?
There is no minimum size, however, for 240 volt operation the heated area must be at least 1.0m².
What happens when a cold night is followed by a warm day?
The heat will stay trapped in the floor when the air temperature exceeds the floor temperature so no heat will rise out of the floor.
How hot does the floor get?
To maintain a 21°C air temperature the floor temperature would be approximately 25°C or approximately 4°C above the desired room air temperature.
Can sections of the heated floor be isolated?
Yes. Multiple zoning with independent thermostats for difference rooms/areas is recommended. This gives greater control of comfort levels (temperatures) and more economical running costs.
Can the system be installed on an existing concrete floor?
The T2QuickNet heating mat is buried in a minimum 30mm cement screed on top of the existing floor. The system operates as a storage system using off-peak electricity or time-of-use.
Can the system be installed on a timber floor?
T2QuickNet heating mats are laid out on the timber floor and glued. A 40mm cement screed is laid over the floor. It then may be connected to off-peak electricity.
How much does it cost to install?
As a guide $190 per m² for the average house.
Delete any permanent fixtures e.g. kitchen cupboards or built in wardrobes. The cost covers supply of heating units and installation of heating units onto the existing floor. The cost also covers the supply of all thermostats and controllers.
