Underfloor Heating

Electric Underfloor Heating Pros and Cons

Underfloor heating used to be seen as a luxury used only in extravagant homes and high-end hotels, but those days are gone and most of us know that it’s now a really affordable option. It’s also really practical, particularly in small spaces where it can be used as a replacement for bulky radiators. As with everything, electric underfloor heating has its pros and cons so we’re going to spell them out for you to help you decide whether it’s right for you or the job you are working on.

Pros of Electric Underfloor Heating

  • Easy to install – compared to other heating systems, electric underfloor heating is relatively easy to install. The mats often have a self-adhesive coating on the underside to fix them to the floor, and they are then covered in a self-levelling compound or tile adhesive. A certified electrician will need to connect the system and ensure it is all working correctly before tiles can be installed.
  • Makes the most of space – in smaller spaces underfloor heating can be used as the sole heating system, freeing up wall space where bulky radiators would usually sit.
  • Ideal for wet rooms – underfloor heating is suitable for use in wet areas, which makes it ideal for use in bathrooms and wet rooms. It helps to evaporate water on tiled floors, minimising the risk of slipping and making the floor safer.
  • Flexible heating option – electric underfloor heating can be installed on any level of the house and because the mats are very slim it is perfect for use in renovation projects.
  • Luxurious experience – there’s no denying that underfloor heating provides a luxurious feeling underfoot – whether you use it in your bedroom, bathroom, kitchen or living areas.

Cons of Electric Underfloor Heating

  • Expert installation – you will need to make sure you hire qualified tradesmen to install the system and keep hold of all information regarding installation in case of any problems in the future.
  • Insulation – to make the most of your electric underfloor heating you may need to install additional insulation beneath the mats. Tile backer boards will help your UFH system work most efficiently.
  • Longer heat up times – electric underfloor heating can take a little longer to heat up than other options, however if you use your thermostat to create a custom heating schedule that suits you it’s unlikely you will notice.
  • Running costs – if you use electric underfloor heating as the only source of heating in your home it may be an expensive choice, however it’s more likely that it will be used for one or two rooms or as an additional heating method – for this it is a cost effective option.
  • Faults – if there are any faults with the system you may need to rip up the floor to fix or replace the electric underfloor heating which will be expensive and disruptive.

From self-adhesive mats to touch screen thermostats, Orbry have a range of underfloor heating products designed to add a touch of luxury to any room in your home.

Orbry strongly recommend adding underfloor heating to wet rooms, as it helps evaporate any surface water that is left on floors after showering. The floor level heating also provides a more consistent heat as it is evenly spread out throughout the entire room. If using underfloor heating as your only heating source you can free up wall space previously taken up by radiators. Radiators can also become dust traps, so removing these is great for those with asthma or allergies.

Product Feature: DEVIflex Loose Lay Cable Electric Underfloor Heating

Product Feature: DEVIflex Loose Lay Cable Electric Underfloor Heating

Electric underfloor heating is fast becoming a popular choice in homes, particularly in bathrooms, wet rooms and kitchens. This is partly due to the affordability of underfloor heating products, but also due to the ease of installation. Electric underfloor heating mats make installation quick and easy, but if you are having to cut the mats repeatedly to fit them into a small or awkward space they can often make the job harder. DEVI have created an innovative loose lay electric underfloor heating cable that combats this problem.

DEVIflex is a heating cable that has been created with its user in mind. When developing the product, which is a replacement for the previous DTIP product, DEVI researched what users wanted and came up with three main design goals:

  1. A great cable strength
  2. Increased cable flexibility
  3. Superior reliability

In order to meet these design goals they created a heating cable that is perfect for using in small spaces, awkward shape rooms, or for those who prefer to lay the cable by hand. The DEVIflex loose lay underfloor heating cable has a twin conductor with a single cold lead cable which aids layout planning and installation. The cold lead cable is now even easier to strip thanks to its 3 solid copper wires.

Key features of DEVIflex cable

  • PVC outer sheath and XLPE insulated inner cable gives strength and flexibility
  • Easy installation thanks to the round construction of the heating cable & cold lead
  • Installation is possible at temperatures as low as -5° provided you allow for a longer installation period
  • Quality and reliability – DEVIflex conforms to IEC: 60800:2009 product standard
  • 360° full aluminium screening ensures maximum protection

Installing DEVIflex Heating Cable

Tips for installing the DEVIflex loose lay underfloor hearing cable:

  • Plan the installation by drawing a sketch which shows cable layout, cold leads & connections, junction box, sensor, connection box & thermostat.
  • Prepare the installation area by ensuring the surface is even, stable, smooth, dry and clean.
  • At low temperatures, heating cables can become rigid. After rolling out the element, briefly connect it to the mains supply to soften the cable before fastening.
  • Cables must not overlap or cross.
  • The heating cable bending diameter must be at lease 6 times the cable diameter.
