Devimat, available from Devex Systems , is designed for house renovations where the construction height of the floors needs to be minimised. The Devimat is 3mm in thickness and the system can be installed on top of existing tiles, wooden floors or concrete floors, as well as over fibre cement and water proofing.

The Devimat heating system is suitable for kitchens and bathrooms, or can be used anywhere in a building in connection with a renovation where new tiles are to be laid. The Devimat heating system is available in two pre-set rates of output. The higher rate of 160W/m2 is used only when the mat is installed directly over or under timber. In the case of deviflex cables, the DSIG-17 and DTIP-18 can be used over concrete, whereas the lower output DTIE-10 should be used when installed directly over or under timber. Both are used in an in screed system.

The Devimat DSVF-150 mat uses a single conductor cable whereas the DTIF mats use a twin conductor cable. The Devimat DSVF-150 mat is recommended when the floor height is crucial. Since the Devimat is 5mm thick (including tile adhesive) the increase in the floor height is minimal.

If the floor height is not crucial, the deviflex cables can be used with an in screed system. If the system is to be laid over a timber floor, the Devimat DTIF-100 or deviflex DTIE-10 must be used, unless fibre cement is used as an underlay.

The Devimat DTIF-100 or deviflex DTIE-10 must always be used if there is to be wood above or directly below the heating element. The devireg 535 programmable thermostat is used to achieve optimal comfort and economy of the system.
