THE EP WARMFLOOR SYSTEM

The underfloor heating system is built up of 34 cm wide and 1,2mm thick elements of carbonenriched polyeten, with copper braid embedded along both edges.

The elements are cut to desired length, and may be connected up to 6,0 metres in one length. All the plastic is electrically conductive. Because of

resistance in the material, heat is developed. The elements have a self-regulating effect.

When the temperature in a room increases, the resistance increases and consumption of electricity decreases. In this manner, the elements can

never be overheated to provide any danger.

The temperature on the element rarely exceeds 27 to 28 °C. Floor

surface temperature will normally be around 25 °C. This provides a

comfortable and healthy floor heating, for both people and animals.

TOTAL OR COMFORT HEATING

EP warmfloor may be used both as comfort and as a total heat source with capacity to heat up single rooms or the whole house. Normal

calculation in living rooms says about 40 to 50 Watt/m 2 , depending on insulation, activity and size. Bathrooms and entrances will normally need a higher wattage, gained by putting the elements closer together. Comfort heating means that you want to avoid a cold floor surface. The elements

are then placed further apart and concentrated to areas where you place your feet. Calculated capacity will then be as low as 30-40 watt/m2.

Then, you will most probably need some additional heat-sources during the

coldest periods of winter.

SAFETY AND HEALTH

The low temperature heating from EP warmfloor, is spread evenly throughout

the floor. A correct floor heating temperature should be at the same

level as underneath your feet. Health Authorities have defined floor temperatures in Kindergartens to be between 19 and 26 °C. In some

countries, for health reasons, it is even prohibited to exceed 28 °C.

The ideal temperature for your head is 19 °C. Heat distribution in a room

with EP warmfloor, is close to ideal, giving a higher temperature at your feet than your head. When your feet are warm, you can lower the room temperature 3-4 degrees and even feel more comfortable.

This low temperature heating also results in better airquality, as no dust is burned or whirled around. The self-regulating effect means that the

elements can not be overheated when run on 24 Volt. This voltage is also

safe to touch if anaccident should occur. A mechanical damage of the floor rarely leads to loss of the heating.

ENVIRONMENTALLY FRIENDLY

Polyetene is an environmentally friendly type of plastic that releases no

gases and is degradeable from sunlight. The plastic can be recycled and

used for other purposes. All other materiasl used in EP warmfloor, are waterbased and unharmful to people and nature.

MAGNETISM AND RADIATION

EP warmfloor has the lowest values in radiation and magnetism. If there are special considerations regarding very sensitive persons, please get in touch with us for special advice.

The element does not disturb electronic devices and may be used in connection with highly sensitive equipment.

ENERGYSAVING
EP warmfloor is very economical in use, with measured savings of more than

40 % compared to conventional heating systems. The reason for
this is a combination of lowtemperatured heating, selfregulation and

closeness to the floor surface. This principle means that it is not
necessary to heat up all underlying materials.

A testhouse has shown amazing results: A winter season of 5 months with

an average outdoor temperature of + 1,5 o C, has shown a consumption of 14,5 Watt/m2 per hour. The norm from Norwegian Building Society, after
energysaving steps have been taken, states 30
Watt/m 2 per hour as an average.

GREAT FLEXIBILITY

The EP element can be placed directly onto floor materials like wood, chipboard, concrete, vinyl and all others that are nonconductive.
This is due to the selfregulating effect and the low temperature. However,

you must always make sure that the connectioning clips are free from daily

tear and ware.
Above the heating system, any floorcovering may be used. Ceramic tiles,  wood and parquet floors are excellent in combination with EP warmfloor.
Vinyl and carpets can also be used when using a thicker layer of selflevelling compound for mechanical strength.

Polyetene is a material with great mechanical strength, flexibility and toughness that can endure mechanical stress. This makes the EP element suitable for a lot of other purposes than floorheating. Other applications are outdoor staircases, entrances, benchheating, bedheating, greenhouses and caravans, pluss biological, medical and industrial use.

INSULATION
No heat source can substitute a defecting insulation. Up to 40 % of the

energy may be wasted by heating up underneath the floor. Therefore,

we always recommend using sheets of 3 or 6mm Kapron insulation

underneath the heating mats.

EASY INSTALLATION

• Roll out the elements and cut into desired lengths.

• Peel off the adhesive backpaper

and press the element to the floor.

• Mount connection clips, install wires and connect to the transformer.

• Check that the system works before covering.

Above this you can install all types of floorcovering. Ceramic tiles may be installed directly, although we sometimes recommend 6-8mm of

selvlevelling compound on top. Wood and parquet needs a layer of parquet
underlayment. Vinyl and carpets need 6 to 10 mm of selflevelling compounds

underneath.

Dependant on the type of floor-construction, you may turn the heat on after 1-7 days.

TEMPERATURE CONTROL

Normally, the selfregulating effect in the EP element will give an adequate control in smaller rooms.

However, autumn and spring give variations that influences on the need for heating, and in some cases it is necessary to control this.

If the warmfloor system is to be used at summer time, it is important that the

floor is kept warm, but at the same time avoiding too much heat in the room.

In this case, some regulation of temperature must be done in addition to the selfregulation in the element.
The best controlling method is by using the EP thermostat/regulator. This device is a combined thermostat and efficiency control, to ensure saving energy. It is also equipped with an automatic night saving switch. The unit also dampens the start-up peak on transformers, to avoid exceptional loads on the net. Bimetal thermostats or timeswitches may also be used, although these have a limited functioning.

If the calculated room temperature is not obtained, it is possible to correct the temperature and effect on the transformer, by increasing the Voltage.
