Devi heating mats are an electric underfloor heating system that is installed under the flooring in a building. They use electrical resistance to generate heat and warm the floor surface, providing comfortable and even heat distribution. Devi underfloor heating kits are commonly used in bathrooms, kitchens, and other areas where tile or stone flooring is used. They are easy to install, energy-efficient, and can be controlled with a thermostat for accurate temperature control. They can also be integrated with other heating systems and smart home technology for added convenience and control.
At Underfloor Heating UK, we provide a comprehensive selection of DEVI heating mats for floor heating solutions. These mats are perfect for both new construction and renovation projects and can be installed in bathrooms, kitchens, conservatories, and other areas. With their thin design and easy installation, DEVI mats make it effortless to install electrical heating systems even in large spaces. Additionally, they come with a 20-year warranty that covers product, installation, and floor replacement costs.
For timber sub-floors, the 100W version is ideal. These mats work best with floor coverings like tiles and vinyl, making them suitable for kitchens and bathrooms.
For concrete sub-floors, a higher power output is needed. The temperature of concrete can vary with weather, so a little extra power is needed to ensure the desired warmth. These mats are suitable for tiles, vinyl, and carpets and can be used in all rooms except those that are particularly susceptible to the cold, such as utility areas.
Rooms that are more affected by the cold, like utility areas, conservatories, and others, require more power. The 200W version offers more power, effectively combating outdoor temperatures. It is suitable for use with vinyl, carpets, and tiles.
The DEVI heating mats are a versatile solution for warming floors in various settings, including homes and businesses. The DEVI mat system is designed to be easy to install, with a hidden design that is simple to size. The mats are CE compliant, ensuring safety, and provide easy control for comfortable heating. The mats are compatible with a variety of flooring types, such as tiles, laminate, and wood, and have a round profile for quick and safe installation, making them an excellent option for floor renovation projects.
What sets DEVI apart from other manufacturers is their Floor Guard Warranty. This warranty not only covers the heating system, but also the flooring itself in the unlikely event that the heating system cannot be repaired due to a manufacturing fault. This comprehensive coverage is unique, as other manufacturers typically only offer product warranties that do not include flooring replacement.

Frequently asked questions
Are electric underfloor heating systems designed to heat a room or just to keep a floor warm?
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.
At what stage of the project should I install my electric underfloor heating?
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.
Can I install the system myself or do I need an expert?
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.
Can I retrofit Underfloor Heating into my property?
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.
Can the backlight in stand-by mode be turned off on the DEVIreg Touch thermostat?
Yes it can.
From the main menu, go to Settings > Options > Dim level, and select OFF. With the same navigation, the safety lock, forecast (adaptive function, both start and end), window open and min. floor temperature can also be turned off.
Can underfloor heating be used in a bathroom or a wet room?
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.
Can underfloor heating be used under carpet?
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.
Do I need a thermostat?
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.
Do I need to change the flooring when I want to install DEVI floor heating in my bathroom?
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.
How do I turn off my underfloor heating system?
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.
I have a floor which is made up of both timber and concrete. Can I use a single heating mat for the floor?
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.
What is an underfloor heating floor sensor?
A floor sensor is a device that is connected to the thermostat, and allows the floor temperature to be fully controlled.
The floor sensor is wired back to the thermostat, and connected to the “NTC” terminal. There is no polarity on the cables.
DEVI always recommends installing a floor sensor. The DEVIreg Touch / 550 / 535 / 540 thermostats can be programmed to operate as any 1 of these 3 options:
- Air sensing
- Floor sensing only
- Air & floor sensing
A Floor sensor must be installed when floor or floor/air sensing is chosen. Without a floor sensor, the maximum floor temperature cannot be controlled. A floor sensor is essential with wood, vinyl or carpet floor coverings.
What is the black thing at the far end of the twin conductor mat?
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.
Which type of thermostat should I choose for my underfloor heating system?
When choosing a thermostat for your underfloor heating system you need to decide what characteristics you want from your thermostat.
Manual - A manual thermostat will provide total control when using your underfloor heating. Simple to use, they are ideal to manually regulate the temperature for almost any underfloor heating application.
Digital - Programmable digital thermostats are a modern and timeless alternative to the manual thermostat, offering complete control for your underfloor heating. Automatically adjusting the heating to meet your comfort level, regardless of changing weather conditions by measuring the floor temperature and combining it with the air temperature.
Touchscreen - A touch screen thermostat will provide stylish total control of your electric underfloor heating system. Touchscreen thermostats can be combined with an existing system, providing a smart yet simple upgrade with advanced intelligent energy-saving features to cut heating bills without compromising comfort.
Will underfloor heating restrict my choice of floor finish?
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.
