The Ultimate Radiant Floor Heating Guide!

Popular Types of Kitchen Backsplashes

Step into a world of comfort and luxury with radiant floor heating, where every step you take becomes an indulgent experience. Say goodbye to chilly mornings and cold floors, and embrace the soothing warmth that rises from beneath your feet. Radiant floor heating, the epitome of modern home innovation, offers a host of benefits that extend beyond mere temperature control.

From energy efficiency to improved indoor air quality, this revolutionary heating system promises to transform your living space into a cozy haven. 

"If you are a builder or a remodeler or a flipper, your investment in this will not only return your investment, but give you a profit," Bob Tschudi, Angi Expert Review Board member.

So, settle in and discover why installing radiant floor heating is the ultimate upgrade for your home.

What Is Radiant Floor Heating?

Radiant floor heating is a heating technology that uses either electrical cables or hot water coils installed beneath your floor to warm your home. The heat generated rises from the feet and circulates naturally throughout your home, warming the people inside. This natural process, called convection, is what makes this method so effective and efficient.

Installing radiant heat can help homeowners save on heating costs because water and electricity are more efficient at transporting heat into a room than air.

How Does Radiant Floor Heating Work?

A radiant floor heating system employs thermal radiation to directly warm the floor of a room rather than relying on heating the air within the space. As a result, the generated heat is not only absorbed by the floor, but also by other objects in the room, leading to an efficient and comprehensive warming of the entire area.

In simpler terms, heated floors leverage the power of radiant heat technology to offer cozy warmth to your feet, which then gently spreads upwards, enveloping the entire room in a highly effective and efficient warming experience.

Types of Radiant Floor Heating

There are two main types of radiant floor heating systems: electronic and hydronic.

  • Hydronic Radiant Floor Heating Systems - Hydronic radiant floor systems heat the floors by circulating hot water through pipes beneath them powered by a boiler system. Although operating costs are cheaper than an electric system, installation is much pricier. It takes longer to install and is best suited for new builds than existing ones. Additionally, hydronic systems need regular maintenance, unlike electric ones.
  • Electric Radiant Floor Heating Systems - Electric radiant floor systems use electric wires to heat floors efficiently. Compared to other heating systems like forced air systems, they're less expensive to install and cost-effective in the long run due to their low electricity usage. Once installed, electric systems require no upkeep.

8 Benefits of Underfloor Systems

Here are the top eight benefits of using an underfloor heating system.

1. Invisible Hardware

Unlike HVAC systems, space heaters, and radiators, underfloor heating systems are designed to be unobtrusive. This characteristic makes them visually appealing as they can blend well with your living spaces, being hardly noticeable.

2. Cost-Effective and Energy-Efficient

Radiant heating systems are more efficient and economical than gas- or boiler-based ones. Unlike traditional radiators, which need to be heated up to 167 degrees Fahrenheit to heat a room, a radiant heating system can heat the same area at just around 84 degrees Fahrenheit. Duct-based heating systems always experience some amount of duct loss.

Radiant heating directly heats the floors, which leads to lower energy loss. This type of heating is highly energy efficient and can save an estimated 15% on heating bills.

3. Compatibility with Smart Thermostat

You can integrate radiant heating systems with Alexa and Google, allowing easy incorporation into your existing systems. Using an intelligent thermostat, you can program preset schedules for your radiant floors, ensuring your home or building consistently provides reliable temperature control.

4. Fewer Limitations on Interior Design

Radiant floor heating allows you to heat your entire space without requiring bulky radiators to take up wall space. This means you have more freedom in designing your space without considering the radiator's placement.

5. It's Maintenance Free!

Once installed, electric-based radiant floor heating systems usually do not require ongoing maintenance or servicing. This factor makes them a hassle-free and low-maintenance option for heating purposes.

6. Compatibility with Any Flooring

Underfloor radiant heating systems can be used with any type of flooring, including wood, laminate, stone, tile, carpet, and more.

  • Tile & Stone: DCM-PRO – highest heat output cable, anti-fracture membrane for tile crack prevention
  • Vinyl / LVT: StickyMat or DCM-PRO
  • Laminate, engineered wood, carpet: foil – no thin-set or leveler required
  • Concrete: in-slab cable

7. Flexible Installation Process

Installing electric radiant floors is easy and can be done simultaneously with installing flooring. Both professionals and DIYers have options available.

8. It helps Improve Air Quality.

Radiant heat is a superior option for maintaining good air quality. Radiators generate excessive heat that may decrease oxygen levels, and the movement of air they cause can circulate dust and impurities around the room. Conversely, radiant flooring preserves a fresher environment and avoids stirring up dirt and debris.

3 Drawbacks with Radiant Floor Heating

Radiant floor heating has several advantages, but it's essential to note a few drawbacks.

  • Having to Replace Old Flooring - If you want to install a radiant heating system, you'll need to remove your existing floors and install new ones. That's why it's wise to set up the floor heating system during a renovation or when installing new flooring.
  • Installation Might Take Longer - You must apply a self-leveling compound on top to install a floor heating system. This compound must be completely dry before putting the floor covering on, which can take a day or two. If you're using a water-based system, the installation time is longer. However, with the DCM-PRO system, you can complete the project in just one day because it is "ready to tile." The FOIL system is even quicker since no thin-set or leveler is required, enabling a same-day installation and use.
  • Floor Height Challenges - Radiant flooring systems come in different heights, ranging from no added size (with foil under carpet) to up to 7/8" in height (using ultralight and DCM-PRO with leveler). Some people also add insulation boards to maximize efficiency, which can increase the floor's size by one inch. Therefore, if the room where you want to install radiant heating is already short, this might cause some height loss, which could be a concern to consider.

Best Home Areas to Install Radiant Floor Heating

Radiant floor heating is an excellent option for areas that tend to be chilly or damp. Warmup systems can be controlled for each room, which makes them very energy-efficient for primary or supplemental heating. You can significantly reduce your energy consumption by only heating the rooms that are in use.

  • Bathrooms - Installing a bathroom floor heating system is a great idea, as tile floors tend to feel cold after a shower. Bathrooms usually have a lot of humidity, damp towels, and tile floors, making them feel particularly chilly during the fall and winter months. Therefore, installing heated bathroom floors can help keep the room comfortable throughout the year.
  • Kitchens - In the fall and winter, kitchens can become uncomfortably cold due to the tile flooring and humidity. Therefore, it's worth considering installing heated floors, especially since the kitchen is one of a home's most frequently used rooms. Radiant floor heating is an excellent option for keeping your kitchen warm and cozy.
  • Bedrooms - Everyone loves a cozy bedroom, and one of the ways to achieve it is by having radiant flooring. It helps keep the temperature warm without increasing the HVAC or using unsafe methods like space heaters.
  • Garages - When considering installing a radiant floor heating system, many overlook including it in their garage. But having heated floors in your garage can be beneficial in keeping snow under control during winter and providing a comfortable space to work on your car or spend time in.
  • Home Offices - Installing heated flooring in your home office is a great way to add lasting comfort and convenience. Since we spend much time at our desks, it's worth considering investing in upgrades to enhance our at-home work experience.
  • Basements - A radiant floor heating system can make your damp and cold basement comfortable during cooler months and keep your whole house warmer because heat rises.
  • Sun Rooms - During spring and summer, sunrooms are great spaces to enjoy the outdoors while being protected from the elements. Sunrooms usually have plenty of windows to provide coolness in the warmer months. However, during winter, those same windows can make the sunroom chilly. To ensure the sunroom is comfortable all year long, installing heated floors is recommended.
  • Driveways - If you reside in an area that often experiences snow and ice, consider installing a radiant heating system under your driveway. Doing so lets you easily remove snow and ice from your driveway by turning on the system. This means you won't have to worry about snow and ice anymore. No new information is included, and no new facts are made up in the rewrite.
  • Tiny Homes and Mobile Homes - Some people prefer to travel in an RV or mobile home, while others opt for a tiny house on wheels or a property in the woods. Radiant floor heat is a reliable heating option for any location or environment.


Consider radiant heat systems an effortless and energy-saving method to keep your home warm and cozy, particularly while renovating your bathroom. You can save on labor costs since the flooring should be lifted and replaced. The comfort and reduced heating expenses will benefit you in the long term.
