I recently installed electric underfloor heating in my bathroom, and I have to say, it was much simpler than I expected. But I’ll admit, I was initially hesitant. I had always assumed that installing underfloor heating was a complex, expensive, and time-consuming process, best left to professionals. I was also unaware of the electrical option, assuming all underfloor heating was based on pipework integrated into a central heating system. And then the thought of pulling up flooring and dealing with wiring or plumbing felt overwhelming. Plus, I wasn’t sure if it would be worth the cost—after all, I had managed just fine with a traditional radiator for years.
However, as winter approached, the idea of stepping onto icy tiles every morning became less appealing. I started researching my options and quickly realized that electric underfloor heating was not only affordable but also surprisingly easy to install. The more I looked into it, the more I saw homeowners like me installing it themselves, with minimal hassle. That gave me the confidence to take the plunge, and I’m so glad I did. Now, every time I walk into my warm, cozy bathroom, I wonder why I didn’t do it sooner! (Please note: a professional electrician completed the installation. This is very important to comply with building regulations, if they are mandatory in your country.)
If you’re considering adding underfloor heating to your home, here’s everything you need to know to make the process as easy and stress-free as possible.
The system I chose is very similar to this: GCCSJ 16 Sqft Heating Mat, 180W 120V Electric Radiant Floor Heating System with WiFi Controlled Thermostatic Tloor Sensor and Cable Monitor, Easy to Install Under Tile, Wood and Marble
Why Choose Underfloor Heating?
Underfloor heating offers even heat distribution, better energy efficiency compared to traditional radiators, and a cleaner aesthetic without the need for bulky heaters. It works well with various flooring types, including tile, laminate, and even carpet (if properly installed). One of the biggest benefits is comfort—no more stepping onto cold floors in the morning (something my wife continually complained about, I should add!) Additionally, it helps free up wall space, allowing for more flexibility in room design and furniture placement.
Another major advantage is energy efficiency. Unlike radiators, which heat the air unevenly and create cold spots, underfloor heating distributes warmth across the entire floor surface. This means you can achieve the same level of warmth at a lower temperature, reducing energy consumption. In well-insulated homes, this can lead to lower heating bills over time.
Underfloor heating is also a healthier option for those with allergies. Traditional radiators cause air to circulate dust and allergens, whereas underfloor heating provides warmth without disrupting air quality. This can make a noticeable difference for people with respiratory issues or sensitivities.
There are two main types of underfloor heating systems:
| Type | Description | Best For |
|---|---|---|
| Electric (Dry) | Uses electric heating mats or wires installed beneath the floor. Quick to install and great for smaller areas like bathrooms. | Small rooms, renovations, DIY installations |
| Water (Wet) | Connected to a central heating system, with warm water circulating through pipes under the floor. More energy-efficient in the long run but requires professional installation. | Whole-house heating, new builds, larger areas |
Since I was working with a small bathroom, the electric system was the best choice. It was a (mostly) straightforward DIY project, and installation only took a few hours. I didn’t have to worry about major plumbing work, and the total cost was much lower than I had anticipated (materials and system: $150; electrician: $150).
Installation Steps for Electric Underfloor Heating
- Plan Your Layout – Before starting, I measured the space and ensured the heating mat would cover the necessary areas, avoiding fixtures like the toilet and vanity.
- Prepare the Floor – The surface must be clean, dry, and level. I installed an insulation board first to improve efficiency and prevent heat loss.
- Lay Substrate – I used insulation boards underneath the mat to reduce heat loss.
- Lay the Heating Mat – The mat rolled out easily, and I secured it using the adhesive backing. It’s important to keep the wires from overlapping.
- Connect the Thermostat – A qualified electrician wired the system into a thermostat to regulate temperature.
- Cover with Flooring – Since I had tiles, I used a floor-levelling compound to ensure a complete level floor, and then applied a flexible adhesive and grout to prevent cracking from heat expansion.
- Test the System – Before sealing everything up, I tested the heating mat to ensure everything was working correctly.
Things to Consider Before Installation
- Cost: Electric underfloor heating is relatively inexpensive upfront, but running costs depend on usage and insulation.
- Power Supply: Ensure your electrical system can handle the extra load.
- Flooring Compatibility: While tile and stone work best due to heat retention, you can install underfloor heating beneath laminate, vinyl, or carpet with proper precautions.
- Installation Complexity: DIY is possible for electric systems, but wet systems require a professional due to plumbing work.
Final Thoughts
Adding underfloor heating to my bathroom has been one of the best home improvements I’ve made. It’s affordable, easy to install, and makes a noticeable difference in comfort. Not only has it improved my mornings by eliminating the shock of cold floors, but it has also enhanced the overall warmth of the room, making it feel more inviting.
One of the things I love most is the ability to control the temperature with a thermostat. I can program it to warm up just before I wake up, so my bathroom is cozy by the time I step in. It’s also energy-efficient—by using it strategically, I don’t need to rely as much on central heating.
If you’re considering underfloor heating, I highly recommend starting with a small space like a bathroom or kitchen before moving on to larger areas. You might be surprised at how simple the process is, even if you’re not particularly handy. The installation was straightforward, and the benefits far outweigh the effort involved. I only wish I had done it sooner!
