Electric floor heating system
Installation and use
We have assembled a list of the most frequently asked questions concerning the installation and use of electric floor heating systems.
Can I install a floor heating system on my own?
You are most welcome to perform the preparation work yourself, but all electrical connections must be made by an electrical technician. However, you can install the Veria Clickmat on your own, as this system is plugged into a ordinary power outlet.
How long will it take the floor to heat?
Electric floor heating reacts quickly, but the amount of time needed before you can feel the heat depends on your floor covering and insulation. That said, it may take anywhere between a few minutes and one hour for your floor to heat.
Which floor area should be covered with floor heating?
As a general rule, the entire room in which you are installing floor heating should be covered. However, you should not install floor heating underneath fixed cabinets (those which touch the ground), bathtubs, and the like.
In the installation guide you'll find detailed information on how to take the room's measurements.
Can I install floor heating underneath a shower cabin?
You should definitely install floor heating underneath your shower cabin, as this area will otherwise feel cold in relation to the rest of your bathroom.
Can the floor heating mats be trimmed?
No, the floor heating mats must not be trimmed, and under no circumstances may the yellow cable be clipped or shortened. If the mat is slightly too large for the desired area, you can take the cable off the mat and run the excess length along the wall.
Note that the cable should never cross over or touch itself.
Can I lay carpeting on top of electric floor heating?
This depends on the rug or carpeting's insulation effect.
It is important for the floor heating system's functionality that you do not "encapsulate" the heating element and thereby prevent the heat from being properly conducted. You should therefore never lay a rug or carpeting with an insulation value higher than 0.175 K/W.
For information about the insulation value of a rug or carpeting, refer to the product manufacturer.
Can I lay heavy wooden flooring over an electric floor heating system?
Yes, you can lay any type of wooden floor over the system, including heavier wood types.
When installing wooden flooring over a floor heating temperature, it is important that the floor temperature does not exceed 27°C, as this level of heat will cause the wood to dry out and crack.
By using a thermostat (such as the Veria Control B35) with a temperature limit of 35°C (measured by the floor temperature), you can ensure that the floor temperature will not exceed 27°C.
What output should I choose?
For wooden or laminate substrate, as well as with a wooden, laminate or carpet floor covering, we recommended a maximum output of 100 W/m2.
With a concrete, regular or quarry tile substrate, as well as with a regular or quarry tile floor covering, we recommend a maximum output of 150 W/m2.
Is insulation needed underneath a floor heating mat?
This depends upon the room in which the floor heating is to be installed. When installing floor heating in an uninsulated basement, we recommend laying an insulation panel underneath the floor heating mat.
For further information about suitable insulation materials, refer to a builders merchants or DIY store.
How thick should the grout/filler layer be over the heating mat?
When installing a wooden floor, laminate, carpet, etc. over the floor heater, the heating mat should be covered by a grout/filler layer of at least 5 mm. This will ensure an even distribution of heat and protect the top layer from overheating.
What type of grout/filler do me recommend for coating?
You can use concrete, thin concrete, self-levelling filler, etc. to coat over the heating mat. You can also use a flexible tile adhesive and both coat and lay tiles in just one step.
If you opt for this solution, it is important to use a plastic serrated filling knife to prevent damage to the cable.
Can I connect more than one mat to the same thermostat?
Up to two heating mats can be connected to the same thermostat. If you install two heating mats to the same thermostat, the thermostat's floor sensor should be installed in between the two mats.
Note that the two mats must be parallel connected, not serial connected.
When should I use floor sensors or room sensors?
We recommend always using a floor sensor to control your floor heating system. For systems installed underneath tile floors, we recommend using a floor sensor, because the right floor temperature is key to creating an optimal level of comfort. For systems installed underneath wooden floors, a floor sensor must always be installed to prevent the surface temperature from exceeding 27°C.
A room sensor should only be used with a floor heating system installed underneath a tiled floor. For tiled floors in which a floor heating system is used as the primary source of heat, it makes sense to control the floor heating based on a combination of input from a floor sensor and room sensor.
This will ensure a set room temperature while preventing the floor heating system from exceeding the desired temperature.
Myths and facts
We often hear arguments against choosing electric floor heating, which is why we would like to debunk all of these myths once and for all, so that you can feel safe and comfortable with your electric floor heating system from Veria.
Floor heating is difficult to install
Floor heating is a solution that can be easily installed under both new and existing flooring, and the installation time is the same regardless of the type of floor covering you may have.
Floor heating can only be used in bathrooms
Floor heating can be used in all types of rooms (read more here) and in all types of buildings (e.g. existing houses, newly built homes, renovated buildings, etc).
Floor heating can only be installed underneath tiled floors
Floor heating can be installed underneath many different floor covering types, including tile, terrazzo, natural stone, linoleum, carpeting, wood, laminate and parquet.
Floor heating has a low installation height, which frees up more space to use the room as you see fit.
Floor heating damages wooden floors
By using a combination of a maximum output of 100 W/m2 and a temperature control thermostat, you can heat your wooden floor gently but effectively, without causing any damage. The temperature control thermostat ensures that your floor's temperature never exceeds 27°C, thereby preventing drying and cracking.
One problem with the system and you'll have to rip up the entire floor
There is no reason to rip up the entire floor in the event of a problem. Any damage or defect can be detected (down to the centimetre), so that only a single tile needs to be removed and repaired. The heating cables are durable and come with a lengthy warranty, and aside from the thermostat relay, there is no other removable parts such as pumps, valves or compressors in the heating system, making it almost maintenance-free.
Floor heating is difficult to regulate
Floor heating is extremely easy to use, and can be controlled in two ways: by using a separate thermostat in each room, or via a simple device consisting of a centrally located main panel, which is used to control sensors and thermostats throughout the house. The control panel is simple, user-friendly and saves energy, as you can set the optimum temperature which will prompt it to work based on a set individual programme.
Floor heating is expensive
A hydronic floor heating system is around 52% more expensive than an electric floor heating system, while a traditional radiator system is 34% more expensive than an electric floor heating system. The average room temperature can be lowered precisely, even by 1-2°C. This means that energy loss can be reduced by 10-20%, which benefits not only your wallet, but the environment as well. It is the least expensive floor heating system available, and the costs of purchasing and operating the system balance out after ten years.
Floor heating is for winter use only
Floor heating can be used all year round, which is especially important on cold days - even in summertime. The floor heating system also provides comfort on warm days when the room temperature is high but the tiles remain extremely cool.
The heat only rises one metre
The temperature distribution throughout the entire room is almost perfect. The temperature at floor level is slightly higher than when measured at the ceiling, which means your feet stay warm without your head becoming too hot.
Floor heating is bad for your health
Floor heating has no adverse effects on your well-being. The heating cables and heating mats are installed directly under the floor and provide an ideal temperature throughout the room. It's nice to walk barefoot on a warm floor - particularly on a hard surface - and it is good for your health, too. Your feet can control the movement of your entire body, which has an indirect effect on your bone structure and prevents sclerosis, and is especially important during periods of growth.
Floor heating leads to swelling of the legs
This condition can only occur if the temperature is too high. Floor heating has no adverse effects on your well-being, and actually optimises air circulation and the room temperature to keep you in good health.
Floor heating increases the amount of dust in the room
Slow air movement does not trap dust. With proper installation and optimum temperature setting, there will be no air circulation, bacteria or allergens, and humidity will be kept to a suitable level. The system is even suitable for people with allergies, as no dust is caught in the air.
