Slab heating cables
If you are planning to build on a concrete slab for a new home or extension, Pyrotenax Electric Storage Floor Heating is the most economical, luxurious and practical form of space heating you can buy.
During construction, electric heating cables are secured to the reinforcing mesh prior to the concrete being poured. These cables heat the slab during regulated heating periods.
How to install
No modifications are needed to the slab.
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.
Heating area
Living room example A
Heating area = 5.0m x 5.8m
= 29.0m²
Example A selection
Slab heating cable - 5.0kw unit
Quantity: 1
Bedroom example B
Room area = 4.0m x 3.5m
= 14m²
Area of fixtures = 2m²
(wardrobe)
Heating area = 14m² - 2m²
= 12.0m²
Example B selection
Slab heating cable - 2.0kw unit
Quantity: 1
Bathroom, toilet, laundry
example C
Room area = 4.4m x 5.0m
= 22m²
Area of fixtures = 6.5m²
(bath, shower, toilet, bench)
Heating area = 22m² - 6.5m²
= 15.5m²
Example C selection
Slab heating cable - 3.0kw unit
Quantity: 1
Applications
Floor coverings
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.

Marble flooring

Terracotta tiles
Travertine tiles
Gentle background warmth
The heat stored inside the concrete slab 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.
Pyrotenax Electric Storage 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
Burning surfaces
Some other heating systems present hazards for children, the elderly or pets
Safety first
The system is securely encased in the concrete floor and operates in silence
Economical and Energy efficient
Heat input to the slab is controlled by wall-mounted or in- slab 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 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 concrete slab 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.
