Floor warming is expanding

New technology in electric floor warming is seeing more energy efficiency cables and streamlined systems that eliminate bulky junction boxes. At the same time systems are getting easier to install, which removes some fear factor for installers not familiar with electrical systems. Today’s floor warming membranes do double or triple duty in positioning cables, providing uncoupling, waterproofing or even insulation. Technology has even developed to extend floor warming into showers themselves, which not only adds comfort but helps dry the shower floor quickly and discourage mold and microbe growth that can occur on lingering wet environments. Smart thermostats allow connections with devices and services to program warmth from afar or allow the system to learn your lifestyle to better provide comfort. Electric floor warming is expanding even in non-traditional areas of the home, with some customers using electric floor warming for primary heat.

The advances for in-floor heating systems are focused on popular societal trends surrounding energy efficiency and ease of installation for the installer. 

Heating cables are becoming more energy efficient, safer, and help to make the installation easier. Features include allowing the installer to make longer runs before making a turn in the layout requiring less cable and reducing stress on the cable. Some heating cables additionally have the hot/cold wire connection contained within the cable itself, which is important when using a click in heating/uncoupling membrane, eliminating bulky junction boxes that need to be cut into the membrane. 

The improvements in heating membrane designs are likewise focused on heating and energy efficiency, using less energy and warming the floor faster. Additional features like uncoupling and waterproofing help reduce installation time, and the design upgrades improve roll memory and prefilling for the installer.

Lastly, thermostats are becoming more complex and technologically advanced. Wi-Fi enabled thermostats are increasing in demand, allowing homeowners to control their heating system through an app right from their phone. Programmable models also allow setting multiple time periods to turn the system on and off.

The use of heated tile and stone flooring use will continue to increase. What has changed in the heated floors for tile and stone lately is how the wire or wire system was installed. In the past, you had to install the wires by themselves or roll out a system where the wire was attached to a mesh mat. The installer would then have to level the balance of the area not heated before beginning installation. The new systems allow incorporation of the wire into the substrate, and the installer is ready to tile.

The floor warming category is really driven by homeowner desire for greater comfort and luxury. The technology drive has been to develop ways for these systems to be used in more locations in the home.

A recent change is the development of installation details for floor warming systems to be installed on shower floors. The challenge of properly waterproofing an electric system in a shower floor and running the heating cables into the shower area while maintaining the integrity and performance of the system has been overcome with this recent set of instructions. Warming the entire shower floor further reduces the potential for mold growth because the floor dries more quickly and thoroughly. It also increases homeowner comfort because the entire floor is warm, not just the area where the hot water is landing.

There has been a noticeable increase in homeowners looking for radiant heating thermostats that add to their home’s decor while also being a reliable way to control their heating system. As an industry, we often forget that the thermostat is the only part of a radiant heating that is visible after installation. Recently we’ve seen significant advancements in the visual appeal of the thermostats from the design to customization options like metal pop-on covers or “skins” with illustrated designs and even high-end crystals added. These options allow a homeowner another opportunity to really express themselves while enjoying the comfort of their heating system. As far as emerging technological trends are concerned, I don’t think that you can overstate the emerging importance of smartphones for the entire radiant floor heating experience. From the very beginning stages of a project to troubleshooting occasional issues with a system that was installed years ago, the technological capabilities of smartphones have proven to be extremely crucial for us and for our customers. This has been particularly true during the COVID-19 outbreak when limiting the number of people on a jobsite has become a priority. We’ve seen a huge uptick in online quotes coming from in the field (up 7.8% from last year) and we’re seeing a lot of consumers utilizing our remote installation supervision service where a radiant heating expert is able to guide an installer through the most important stages of the process using video conferencing. Interesting times call for interesting ways in how we use technology to overcome limitations.

Customers are demanding versatility from an end-user’s perspective, tied to several points – broadened usage options for more areas in a home. In some cases, it is being used as the primary heat source in many rooms. 

From a productivity/ease of installation view from an installer’s perspective, we are noticing the following trends and insights:

New product introductions/innovation that allow for simpler, quicker, more efficient and consistent installations, which can help tile installers who may not have any electrical experience feel more comfortable with more parts of the installation. It can also help shorten the learning curve for new installers, as well as minimize potential issues once the installation is completed.

Customers are requesting that their floor heating system be integrated into the smart-home eco-system, for efficiency and familiarity, all tied to ease of use. We continue to look for ways to seamlessly integrate our installation systems into the daily routine of life to create a better customer experience.

Due to load-bearing weight and structural subfloor movement, floor finishes can get damaged and tiles are especially prone to cracking. Electric underfloor heating membranes that incorporate an uncoupling design results in significant protection for tiled flooring by creating a new layer between the subfloor and the floor finish.
