Maintenance

Do the systems require any maintenance?
No, they are virtually "maintenance free" because there are no moving parts to break down and no grills or ducts to clean and maintain. Compared to alternative central heating systems such as ducted gas or hydronic systems, DEVI radiant heating systems are truly maintenance free.

Is it possible for a heating cable to become faulty or burn out?
In a properly designed installation, controlled by Devireg™ floor sensing thermostats the cable will not be allowed to run hot enough to cause damage. There is a greater possibility for damage to occur during the concrete pour, or at a later date if holes are drilled into the slab or changes are made to the placement of cupboards or built-ins.

If the heating cable is damaged, can it be repaired?
Damage detected during the concrete pour or damage occurring during the later stages of building work, can be located and repaired using special testing equipment. Since the DEVI cable does not absorb moisture, repairing the cable is very straight forward and does not require a large access hole.

Will a room overheat on a sunny day following a cool night?
Yes, if the building is not well insulated, has large areas of glass facing north and if the heating is controlled by means of "air thermostats". This is likely to cause an uncomfortable temperature overshoot. The use of Devireg™ floor sensing thermostats combined with adequate levels of thermal insulation helps overcome these problems.

What happens if the floor gets wet?
Flooding of any floor heated area should not affect the heating cables in any way. However, the electrical connections at the wall mounted connection box will need to be checked by a qualified electrician along with all other electrical connections and equipment.

I am going away, should I turn the heating off?
If you are away for only two or three days it is advisable to leave your floor heating switched on (you may wish to turn your thermostat to a slightly lower setting and reset it when you return).
If your absence will be extended, it may be advisable to turn your heating off completely - but don't forget that when you return you may need more than 24 hours before your floor heating will be fully effective again. (If the heating is operated on about 10ºC or "2" on the graduated scale, it will help to avoid condensation and will decrease the time taken to warm back up.)
