In Quebec, heated flooring has become an increasingly sought-after solution to improve home comfort, particularly in rooms where ceramic tiles are prevalent. Bathroom, kitchen, entrance, or basement: instead of walking on a cold surface, the system diffuses heat directly from the floor to create a more pleasant and uniform temperature.

But before starting a project, several questions arise. Should you choose an electric or glycol heated floor? Can it be installed under ceramic, engineered wood, or floating floors? What role do the membrane and thermostat play? And most importantly, how much does heated flooring cost and what will its electricity consumption be?

Here is our complete guide to understanding the different systems and making the right choice for your project.

What is heated flooring and how does it work?

Heated flooring is a system that diffuses heat directly under the floor covering. Depending on the chosen system, this heat is produced by electrical cables or by a network of pipes through which a heated liquid circulates. The heat then gradually spreads throughout the room from the floor.

Unlike a heating source installed on a wall, heat therefore comes from a large surface area. This diffusion notably provides a very pleasant feeling of comfort at foot level.

The system is generally controlled using a heated flooring thermostat, which allows you to set the temperature and, depending on the model, program different heating schedules.

However, it is necessary to distinguish between the two main families of systems: electric heated flooring and hydronic systems.

Electric or glycol heated flooring: which to choose?

Both systems pursue the same objective, but their operation and applications are different.

Electric heated flooring

Electric heated flooring works with a heating cable installed under the floor covering. It is particularly interesting for renovations and for targeted areas such as a bathroom, kitchen, or entrance.

Its installation is relatively simple compared to a hydronic system, especially when renovation work already includes replacing the floor covering.

Hydronic or glycol heated flooring

Glycol heated flooring, also called a hydronic system, instead uses pipes through which a heated liquid circulates. This type of system is more often considered for large areas or in certain new construction and major renovation projects.

Therefore, there is no universally better system than the other. The right choice mainly depends on the area to be heated, the type of renovation, the chosen flooring, and the existing installation.

Under which floor coverings can heated flooring be installed?

The compatibility between the heating system and the floor covering is an essential element of the project. Ceramic tile is particularly well suited, but other coverings can also be compatible under certain conditions.

Ceramic Tile

Ceramic tile is one of the most popular coverings with heated flooring. It efficiently conducts heat and is particularly well suited for bathrooms, kitchens, and entrances.

The combination of ceramic tile and heated flooring thus allows for retaining the practical and aesthetic advantages of ceramic tile while significantly improving the comfort of the surface.

Engineered Wood

Some engineered wood floors can be installed with a heated flooring system. However, it is essential to check the manufacturer's recommendations before selecting the product.

Wood reacts to variations in temperature and humidity. The system, installation method, maximum permissible temperature, and product characteristics must therefore be taken into consideration.

Floating Floor

Some floating floors are also designed to be compatible with a heating system. Again, this compatibility must be confirmed for the specific product chosen, rather than assumed for the entire category.

To remember: if you plan to install heated flooring, mention it from the beginning of your shopping. The heating system, flooring, and installation method must be considered together.

Why install heated flooring in a bathroom?

Heated flooring is particularly appealing in a bathroom because it combines the practicality of ceramic tile with a much more comfortable surface underfoot. It can also be programmed so that the floor reaches a pleasant temperature at times when the room is most used.

This is precisely one of the applications we regularly see in renovation projects.

The bathroom is often a relatively small room where a large part of the floor is covered with ceramic tile. Adding bathroom heated flooring can therefore make a noticeable difference to daily comfort without necessarily needing to heat a very large area.

The thermostat programming allows, for example, to set a more comfortable temperature upon waking and to reduce it when the room is less used.

Membrane, cable, and thermostat: understanding the components of electric heated flooring

When shopping for an electrical system, several terms come up: heated floor membrane, heating cable, thermostat, and power module. Each component plays a different role.

The membrane serves as a support for the cable in some systems and facilitates its positioning according to the room's configuration. Depending on the product used, it can also fulfill other functions in the floor assembly.

The heating cable is the element that generates heat. Its arrangement is planned based on the actual heated area and the room's configuration.

The thermostat , in turn, allows control of the system. Many modern thermostats offer programmable schedules and various functions to better adapt the heating to household habits.

Finally, depending on the system's power and area, a power module may be necessary.

How much does heated floor installation cost?

The cost of a heated floor varies depending on the area, the chosen system, the room configuration, the thermostat, the subfloor preparation, and the necessary installation work. To get a representative cost, the project must therefore be evaluated as a whole rather than solely based on the heating cable price.

A small bathroom and a large open-plan area obviously do not require the same system.

Among the elements that can influence the budget are the actual heated area, the type of membrane and cable, the chosen thermostat, the possible presence of a power module, the floor covering, and the complexity of the installation.

Related work must also be considered. In a renovation project, the condition of the subfloor and the preparation required before installation can influence the final cost.

That's why an estimate based on the actual characteristics of the project remains the best way to establish a budget.

Does a heated floor significantly increase the electricity bill?

The electrical consumption of a heated floor mainly depends on the heated area, the system's power, insulation, the desired temperature, and the operating hours. A programmable thermostat can help avoid unnecessarily keeping the floor at a high temperature when the room is not in use.

It is therefore difficult to assign universal consumption to all heated floors.

A bathroom heated during certain times of the day will obviously not have the same needs as a large area maintained at a constant temperature.

Potential energy savings must also be evaluated based on the entire building and the role the heated floor plays in the home's heating system.

Which thermostat to choose for a heated floor?

The thermostat is an important component of the system as it directly influences how you will use your heated floor.

To make your choice, check in particular:

●      its compatibility with the installed system;

●      the power it can control;

●      programming possibilities;

●      floor temperature control;

●      smart functions or connectivity, if desired.

A programmable thermostat for heated floors can be particularly practical in a bathroom. For example, you can program the system so that the floor is comfortable before you wake up, rather than keeping it at the same temperature all night.

The total power of the system must also be taken into account to determine if an additional module is required.

Our specialists' advice: choose the floor and the system together

"If you're considering installing a heated floor, talk about it at the very beginning of your project. The choice of flooring shouldn't be made separately from the heating system. This way, we can check product compatibility, plan for the right components, and ensure the entire project is consistent before installation."
 — Emy Kossom, General Manager

This planning is particularly important when you want to install engineered wood or floating floors, as recommendations can vary from one product to another.

For ceramic tiles, too, the entire assembly must be considered: subfloor, membrane, heating system, mortar, and covering.

Frequently Asked Questions about Heated Floors

Can a heated floor be installed throughout the house?

Yes, some systems can cover large areas. However, the relevance of the system, its design, and its cost must be evaluated according to the building. A system intended for a bathroom is not necessarily designed in the same way as a system covering several rooms.

Can a heated floor be installed under a vanity?

The cable's arrangement must comply with the requirements of the system used and take into account the room's fixed elements. The areas to be heated must therefore be determined before installation rather than simply covering the entire floor.

How long does it take for a heated floor to get warm?

The time required varies depending on the system, the flooring, the floor assembly, and the starting temperature. This is partly why thermostat programming is advantageous: it allows heating to begin before the desired comfort time.

Can a heated floor be added during a renovation?

Yes. A renovation where the floor covering has already been removed is an excellent opportunity to consider adding a heating system. However, available height, subfloor, planned covering, and electrical or mechanical requirements of the chosen system must be checked.

What is the lifespan of a heated floor?

A correctly selected and installed system is designed as a durable solution. However, the exact lifespan depends on the system and its components. It is therefore important to follow the manufacturer's instructions and prescribed installation methods.

Planning your heated floor project properly

Installing a heated floor is not just about adding a cable under ceramic tiles. The heating system, membrane, thermostat, flooring, and installation method form a whole that must be planned according to your room and your needs.
