Frequently asked questions

Underfloor Heating UK DEVI systems are suitable for both heating the entire room or floor only, depending on your requirements.

Poorly insulated areas and in very cold conditions, may require additional heating if you wish to ensure that the room is well heated. Using insulation and a higher heat output system will reduce the need for this.

At Underfloor Heating UK we offer a free expert design service to help you ensure that your Underfloor Heating UK DEVI heating system heats as much or as little as you need.

Generally, we would advise that the property should be airtight before the installation of underfloor heating, but this would also depend on the schedule of your individual project.

All of our Underfloor Heating mats come with a full set of installation instructions, providing a simple step by step guide. Most systems can be installed on a DIY basis. But the final electrical connection should be made by a qualified electrician.

Installation of underfloor heating is obviously easier within a new build project, but if designed correctly, you can still enjoy the benefits of heating your property using underfloor heat on a retrofit basis.

Yes, underfloor heating is a great way to warm your home. It’s lovely to walk on and distributes heat evenly around each corner of the room, freeing your walls from radiators, so its not surprising that the bathroom is the most popular place to install electric underfloor heating. However, it is common practice to locate the thermostat on an outside wall (typically on the landing or in the hall) with the floor probe running through the wall into the floor where the heating is installed.

Underfloor heating can be used with most types of carpet. A self-levelling compound is required and as long as the underlay is not a good thermal insulator (i.e not felt), heat will easily pass through this layer into the carpet itself. The overall Tog value of carpet and underlay combined should not exceed 2.5 with the underlay itself not exceeding 1 Tog.

Yes, we include a DEVIreg Touch programmable thermostat in all of our kits. This stylish cutting edge thermostat uses pulse width modulation with optimum start and optimum end programming as well as open window detection to guarantee extremely high temperature control accuracy, ensuring the DEVIreg touch is one of the most efficient Underfloor Heating controls available.

An easy and clean solution such as DEVImat gives you possibility to leave an old floor without removing it and creating unnecessary mess. The thought of broken up floors and craftsmen running in and out of the house used to be enough for most people to simply drop the idea of having their feet and floors heated.

Today, there is no need to shiver when thinking about floor heating. You are able to get a warm floor without going through the expenses, dirt, and fuss of having to break up the old floor.

The DEVImat is only between 2.3 mm and 4 mm thick, depending on type. It can therefore easily be fitted directly on to your existing floor, whether it is concrete, timber or even an old tiled or terrazzo surface, without needing to cut up the existing floor construction.

The DEVImat is installed within the thickness of the tile adhesives and, therefore, adds no significant height to the floor level. Consequently, there should be no need to reduce door heights, raise skirting boards, etc.

During the summer months or when it is warm, you may wish to turn off your underfloor heating. All of our thermostats have an on/off switch, which can be used to turn off your underfloor heating system.

We strongly recommends that each section of floor with a different covering has its own ‘mat’ as well as thermostat since each floor surface has a different maximum temperature limit. We advise to use a thermostat with a floor heating sensor.

Please contact us to discuss the best options for this floor.

This is the connection at the end of the twin conductor mat where the heating element is connected to the neutral return. This is manufactured within the cable.

The correct floor covering should be carefully considered to ensure heat is not prevented from rising into the room by the floor covering. We offer expert advice on floor covering to ensure the best results without restricting the design of your home.

DEVIcomfort 100w/m2 DTIR-100 2.5m2 250W Underfloor Heating Kit

As in section 1 lack of installation information.

Your service was quick and efficient. My concern was with the DEVI product information and installation information. I have previously fitted a DEVI mat however the installation information was minimal and no explanation given for the pack content. Fortunately I remembered most of the installation steps. The one that I didn't was answered by DEVI customer help. My point is that the product is good but the installation information is poor as is the online information. If DEVI ask you can feed back this information to them.
