Question 1:
Does the heating cause structural damage such as cracking of the slab or tiles?

Answer:
No. A properly designed floor heating system does not overheat the concrete or tiled surface. The concrete is typically heated to a maximum temperature in the range of 25°C to 45°C, much less than the temperature a concrete footpath would experience on a hot sunny day.

Question 2:
Is it possible for the heating cable to become faulty or burn out?

Answer:
If the system is properly designed and installed, and it is controlled by a deviregT floor sensing thermostat, the cable will not be allowed to run hot enough to cause damage.

Question 3:
If the heating cable is damaged can it be repaired?

Answer:
Should a cable be damaged either during or after construction, the location can be detected using special testing equipment. Repairing a cable is normally straight forward and can usually be confined to a small area.

Question 4:
Do the systems require any maintenance?

Answer:
No. They are virtually 'maintenance free' because there are no moving parts to break down, and no grills or ducting to clean and maintain. Compared to alternative central heating systems such as ducted gas or Hydronic systems, DEVI floor heating systems are truly maintenance free.

Question 5:
If the heating cable is damaged can it be repaired?

Answer:
Should a cable be damaged either during or after construction, the location can be detected using special testing equipment. Repairing a cable is normally straight forward and can usually be confined to a small area.

Question 6:
I have a tiled floor over both a timber and a concrete floor structure. Which mat should I use?

Answer:
We would recommend that each section of floor has its own 'mat' and thermostat. In this case, each mat would have its own floor sensor preventing an uneven temperature between the two floor areas. DSVF-160 would be recommended over the concrete floor and DTIF-110 would be recommended over the timber floor.

Question 7:
Can I put Devimat underneath bath / shower tray / kitchen units etc?

Answer:
We do not recommend any heating to be installed under such fixtures for a number of reasons.
   1. It can inhibit the flow of heat being produced from the system
   2. If ever a fault was to occur, it can be very difficult to carry out a repair.

Question 8:
Can floor heating be installed into a thin adhesive bed?

Answer:
Yes, it is possible to install a DevimatT on top of most existing floor surfaces, including concrete, timber, fibre cement sheet and existing tiles using a thin adhesive bed or levelling compound.

Question 9:
Can Elite Floor Heating inspect my home and advise us of the best products to use?

Answer:
Yes we would be happy to advise you on the best products for your home considering the number of rooms required to be heated and the size of each room.

Question 10:
I have a tiled floor over both a timber and a concrete floor structure. Which mat should I use?

Answer:
We would recommend that each section of floor has its own 'mat' and thermostat. In this case, each mat would have its own floor sensor preventing an uneven temperature between the two floor areas. DSVF-160 would be recommended over the concrete floor and DTIF-110 would be recommended over the timber floor.

Question 11:
How long does the heating system take to warm up?

Answer:
This depends on various factors, such as:

• The type of system installed
• The output of the system versus heat loss of the room
• The distance of the cable from the floor surface

This could be anything from 30 minutes for a DevimatT under tiles, to 5-7 hours or more for a storage system.

Question 12:
What is the difference between twin and single conductor cables and mats?

Answer:
The difference between the two is the 'cold tail'. With the twin conductor, there is no second connection tail to return to the thermostat. With the single conductor there is a cold tail at each end of the cable or mat and they have to be brought back together at the connection point. The twin conductors have a very low Electromagnetic radiation (EMF). Both the single conductors and twin conductor cable and mats are well within recommended EMF standards.

Question 13:
Can suspended slabs be heated?

Answer:
Yes they can. However, the exposed underside of the slab must be insulated to minimise downward heat losses. Styrofoam and/or polystyrene insulation boards are often used.

Question 14:
What level of home insulation is recommended?

Answer:
We recommend that you provide for at least the minimum requirements as set out in the BCA. We also recommend the use of perimeter and under floor insulation to the slab itself, particularly in cold areas. The higher the levels of insulation, the lower the running costs.

Question 15:
Is supplementary heating required?

Answer:
If steady 24 hour a day warmth is required, the building is well insulated and the correct electricity tariff is used, then generally no supplementary heating is required.
