Yes, retrofitting underfloor heating into your home is not just possible, but also increasingly popular. Renovating a house doesn’t present the blank canvas that a new build does, yet modern retrofit radiant floor heating systems are designed to integrate seamlessly.
With advancements in technology, solutions are available to overcome architectural challenges, ensuring a warm and comfortable home regardless of its age or design.
The beauty of electric radiant heating is its flexibility. If there’s access to floor joists from below, such as in unfinished basements, adding radiant heating is straightforward without the need to alter the flooring above.
Even with finished ceilings or floors, the process is as simple as removing the ceiling drywall, installing the heating system, and then replacing the drywall. Your pristine floors remain untouched.
Absolutely. While the process of retrofitting is inherently more complex than installations in new constructions, it’s less daunting and more affordable than many homeowners imagine.
The efficiency and luxury of underfloor heating retrofit can elevate the living experience.
Moreover, in most retrofit projects, homeowners won’t need to tear up the existing floor completely, making it a more accessible choice for many.
Electric radiant heating mats, thin and efficient, are stapled to the subfloor between the joists and beneath the finished flooring.
The heat radiates upwards, seamlessly transitioning through the subfloor and the flooring above. This ensures warmth and comfort throughout the year without any major alterations to your current flooring.
Evaluate the floor joists’ accessibility, either from basements or crawl spaces.
Ensure compatibility with your chosen flooring type, and ascertain insulation requirements for optimal heat direction.
Begin by precisely measuring the required area. Once done, cut the radiant heating mats accordingly.
These mats then need to be fastened using staples to the subfloor, resting snugly between the joists.
Wiring is the subsequent step, where each heating element is connected with a pair of wires that merge with the transformer.
After ensuring all connections are secure, insulation comes into play. Use either batt or rigid foam insulation behind the heating elements, ensuring an upward trajectory of heat.
Thin electric heating mats, transformers, and insulation materials like batt or rigid foam.
Expect an average spend between $7.90 to $15.00 per ft², amounting to approximately $790 – $1,500 for a 100 ft² area.

Before initiating the retrofit process in bedrooms and bathrooms, ensure you can access the floor joists.
Unlike the 1st floor, these rooms might not have the advantage of an unfinished basement below.
You may find finished ceilings that could necessitate some drywall adjustments.
When retrofitting the 2nd floor, especially the bedrooms and bathrooms, factor in the type of flooring.
Bathrooms often have moisture-resistant flooring, and bedrooms may have carpet or hardwood.
Ensure the radiant heating system is compatible with these different floor types.
Start by precisely mapping out the area that requires heating. Based on this, trim the radiant heating mats to fit these specifications.
Next, securely fasten these mats to the subfloor using staples, ensuring they’re situated between the joists for maximum effectiveness.
Always use a qualified electrician for any electrical work required in a retrofit renovation project.
The next stage involves wiring: each heating element should be connected with a pair of wires that subsequently link to the transformer.
After ensuring all connections are in place and functioning correctly, it’s time for insulation.
Depending on the specific needs of the bedroom or bathroom, choose either batt or rigid foam insulation.
This insulation should be positioned behind the heating elements, which guarantees that the heat is directed upwards, ensuring a cozy environment.
If you plan on using foil insulation with electric radiant heat you must ensure there is a barrier between the insulation and the heating element
Similar to the first floor, you’ll need heating mats, transformers, and insulation.
The costs remain the same as with first floor retrofits with the budget ranging between $7.90 to $14.00 per ft².
Basements inherently feel colder. Ensuring that the retrofit covers the entirety of the space will ensure uniform warmth.
When embedding radiant heating in a concrete slab, it’s essential to acknowledge that concrete is an excellent conductor of heat, making it an efficient choice for this type of heating.
However, moisture issues and the quality of the slab are factors to consider before installation.
Same Materials as above.
$7.9 to $14.00 per ft².
For optimal heat direction, employ either batt or dense foam insulation behind the heating mats. This ensures the heat is channeled upwards, creating an ambient atmosphere.
Typically, with proper installation and maintenance, these systems can last several decades, offering consistent performance for half a lifetime or more.
Electric radiant floor heating systems are highly efficient, especially those operating on 24V ESLV.
Their broader coverage area ensures less energy consumption while delivering heightened comfort.
Yes, many modern electric radiant floor heating systems come with zonal control, allowing you to manage temperatures based on individual room or area needs
Choosing to retrofit underfloor heating is a game-changer for home renovation projects. It combines the luxury of warmth with the efficiency of modern technology.
Whether looking to upgrade a basement, bedroom, or living space, electric radiant floor heating is an investment in unparalleled comfort that you will enjoy for decades.
