How to Choose the Ideal Floor Heating System

Even with a cozy heating temperature, maintaining warm feet during chilly winter days can be challenging. For those of us who shiver as soon as winter veers its ugly nose, and long for warm summer days, there’s a way to spare the discomfort of frozen toes: getting a floor heating system installed.

Deciding on installing a heated floor system in the family home means choosing a comfortable and evenly heated household. 

When faced with making an informed decision to purchase such a system, you have to clearly understand the related benefits of each type of floor heating system as well as the costs involved. 

Electric or Hydronic: Which Floor Heating Is Best?

Floor heating is a heating system renowned for its efficiency, but also for the comfort it brings a household. While its installation is more costly compared to a radiator heating system, its equipment remains more modern and healthier for that of your family. 

There are two types of floor heating systems:

• An electric floor heating system emits infrared rays that heat the floor and nearby walls.

• The hydronic floor heating system channels a liquid through its piping; the liquid is preheated since it’s from a heat pump or boiler.

Hydronic Radiant Floor

To ensure that the radiant floor heating you chose specifically meets your needs, consider the information provided below. Generally speaking, a hydronic radiant floor is more efficient in areas with larger square footage compared to smaller-sized spaces. 

Since having access to a hot water source is imperative to carry out its installation, the costs related to purchasing a heat pump or a boiler can be rather steep if the floor heating system is intended for a small surface.  

Having hydronic floor heating means one can benefit from a system that may also have a cooling function, meaning homeowners can heat and cool their floors based on circumstantial needs. While this dual-function model is more expensive, it allows one to benefit from their hydronic floor year-round. 

Condensing boilers supply water for heated floors

An increasing number of people are opting for the installation of a condensing boiler, as it stands as one of the most efficient boiler models available on the market. The condensing boiler boasts several advantages, most notably the fact that energy losses (fumes, steam) are a result of recovered combustion, which is subsequently transformed into thermal energy.

Electric Underfloor Heating System

When it comes to electric underfloor heating, this system is well-suited for areas with smaller square footage. Note that this type of heating system offers excellent value for money. If you’re considering a D.I.Y. installation for your radiant floor system, note that it’s feasible. Also, not only is this type of underfloor heating system easy to install, but it also requires less tedious maintenance compared to a hydronic system.

However, opting for this type of floor entails another bit of decision-making: choosing between a loose cable or mesh mat system. The former involves a network of cables with predetermined lengths, making it impossible to extend or shorten. This installation requires pouring self-levelling cement to ensure the cables adhere properly to the ground.

As for the mesh mat system, the latter is sold in roll format. If you anticipate the need to trim the material in several places, this could potentially be more time- and labour-intensive. However, this system benefits from not requiring self-levelling cement during installation. In fact, the heating cable is already fitted to fibreglass meshes.

In actuality, the surface area where the heating cables are installed works similarly to a really big radiator, heating from below. Needless to say, this little bit of luxury is especially appreciated during winter. Radiant floor heating offers a host of advantages, of which we can mention:

1- Comfort and well-being

One of the main advantages of a radiant floor is without a doubt the comfort it provides. This type of installation generates a gentle and evenly distributed heat to the overall surface under which it’s installed. Therefore, there’s no heat loss or sudden temperature spikes, as it maintains constant heat for continuous comfort. Its thermal comfort far exceeds that of all other common types of heating since the heat is evenly distributed in every room, both vertically and horizontally. 

2- Space gain

Radiant floor heating systems have the benefit of being installed beneath the flooring, rendering it completely concealed. The floor plan and the furniture positioning in rooms are thus not affected at all. Since there aren’t any baseboard heaters lined up against the bottom section of your walls, you have the entire floor plan at your disposal to position your furniture and window treatments, or any other decorative feature, wherever you see fit. 

3- Quick-drying floor

When installed in humidity-prone areas, like a bathroom or kitchen, radiant floor heating prevents flooring from remaining wet for extended periods. Consequently, there's less risk of humidity-caused damage. The same concept applies when mopping the floors around the house with water. While most heating systems will help dry the flooring after one or maybe two hours, with radiant underfloor heating, the drying time is cut down to minutes.

4- Noiseless

Heated floors are completely inaudible since they don’t function with a motor or fan, which is the primary cause of the wind tunnel effect. This precious commodity is especially appreciated by those who are triggered by, or sensitive to, noise, but also by individuals who suffer from different dust-related health problems or allergies. This type of heating system functions through radiation, therefore it doesn’t emit dust, unlike traditional heaters. This is a significant advantage for individuals suffering from respiratory-related illnesses. 

5- Energy saving

Although its initial installation entails a significant investment, the benefits of a heated floor can lead to substantial long-term savings. Nonetheless, determining the exact amount saved can be challenging to pinpoint since it really depends on the specifics of the house in which it’s installed, especially insulation-wise.

What type of flooring should be installed over heated floors?

Choosing flooring that’s compatible with the heat generated by the underfloor heating system is crucial. However, the heating pipes and cables can be installed beneath several layers of flooring. But, you’ll still have to choose materials that can retain and store the heat generated for as long as possible, and among these heat-conductive materials, there are concrete, natural stores, and ceramic tiles.

On the other hand, steer clear of flexible flooring, the latter will act as insulation. For that reason alone, carpeting is advised against, as carpet is a material that’ll create a complex transmission barrier between the floor surface and the space above it. Similarly, both linoleum and vinyl sheet flooring shouldn’t be paired with underfloor heating, just as wood is ill-fitted due to its susceptibility to temperature changes.
