How to Choose the Best Floor Heating System Supplier in Toronto and Canada
The best floor heating supplier in Toronto is not the one with the cheapest cable. It is the company that makes its own CSA certified product, draws a layout and a heat-loss calculation for your room before shipping, and backs the cable with a Canadian warranty of 20 years or more.
That matters because a heated floor is a one-shot decision. The cable goes down, the tile goes over it, and nobody touches it again until the room is renovated. Toronto complicates it further: a condo has height limits and a board, a century home has 60 amp service and no panel space, a new build is pouring concrete anyway.
Ontario also does not license floor heating suppliers in 2026. It regulates the product and the wiring instead: a CSA or equivalent approval mark on every cable, mat and thermostat, an Electrical Safety Authority notification before the system is covered, and an ECRA/ESA licensed contractor on the branch circuit. The seller sits outside all of it, so the vetting falls to you.
What This Comes Down To
- Ontario regulates the product and the wiring, not the seller, so verify the CSA mark and the electrician’s licence yourself.
- Three kinds of company sell floor heating here, and only one of them owns your layout and your warranty.
- Electric floor heating runs $5 to $20 per square foot in materials and $16 to $30 installed. Hydronic pays off where concrete is being poured.
- A 100 square foot bathroom costs roughly $12 to $20 a month to run through a Toronto winter on off-peak rates.
- Wattage per square foot and floor sensor placement decide performance. The brand on the box does not.
- Two quotes compare only when both state the same wattage, the same thermostat, and whether the electrical work is in or out.
Electric or Hydronic: What Are You Actually Buying?
Two technologies, and the building usually makes the choice: electric for single rooms and retrofits, hydronic for poured slabs.
Electric floor heating systems put a cable or mat under the floor surface on a dedicated circuit, controlled by a thermostat with a floor sensor. They add about an eighth of an inch of height, heat quickly, and suit existing homes and renovations because installation never touches the mechanical room. Hydronic radiant floor heating systems circulate hot water through pipes in concrete, which is suitable for new homes and large areas but needs a boiler, a manifold and enough floor height for concrete over insulation.
Either way, radiant heating systems behave differently from forced air heating. Forced air systems push warm air through ducts, the warmth rises to the ceiling and the floor surface stays cold. Radiant heat goes into the floor, the walls and the objects in the room, creating even warmth with no air circulation moving dust and allergens around the space. That is the efficiency argument: the same comfort at a lower thermostat setting, using less energy to get there.
What Kinds of Company Sell Floor Heating in Toronto?
Three: manufacturers, brands selling through dealers, and tile shops or wholesalers. Which one you buy from decides who is accountable when a cable reads open on a meter three years from now.
| Type of company | Who makes the product | Who owns the layout and warranty | Who you call when it fails | Best suited to |
|---|---|---|---|---|
| Manufacturer | Builds its own cable, mats and controls | The manufacturer, directly | One company, in your time zone | Custom rooms, whole properties, anything outdoors |
| Brand with a dealer network | The brand; the dealer resells | Brand owns warranty, dealer owns the sale | Dealer first, brand second | Standard rooms where a stock kit fits |
| Tile shop or wholesaler | Distribute several brands, none of them theirs | Nobody on the invoice | Back to whichever manufacturer made it | Installers who know the exact kit already |
On anything custom, outdoors, or in an older house, single-party accountability is worth paying for, because a warranty claim routed through three companies is a claim nobody owns.
What Should You Verify Before Price Comes Up?
Five things, and four of them should reach you from somewhere other than the salesperson. Research the product, not the pitch.
Confirm the CSA or equivalent mark on the product itself, against the Electrical Safety Authority’s list of recognized marks. Confirm the electrician holds an ECRA/ESA contractor licence, verifiable in the ESA contractor search. Confirm the ESA notification is in someone’s scope, in writing, because the system must be inspected before tile or concrete covers it. Ask for the warranty document rather than a number of years, and ask which Canadian entity honours it, since a thirty year promise administered overseas is a shipping problem in year twelve.
If the system is hydronic and the boiler burns gas, the gas fitting sits with a TSSA registered contractor. That is a separate credential from the electrical licence, and separate again from the company selling you pipe.
What Decides Whether a Heated Floor Performs?
Wattage per square foot and floor sensor placement, not the brand on the box. This is the variable almost nobody asks about, and it is the one that produces cold spots.
Residential floor heating runs 12 to 15 watts per square foot for comfort heat. Push higher and the floor overheats and the thermostat short cycles. Go lower, or space the cable too far apart, and you get warm stripes with cold tile between them.
Ask three things. What wattage is specified and why that number for this space. Whether a heat-loss calculation was run if the floor is the only heat source. And where the floor sensor goes, which is between two cable runs and never on top of one, because a sensor sitting on a cable reads hot and starves the room.
Insulation under the element matters as much as the element itself. On heated basement floors especially, heat put into an uninsulated slab goes straight into the ground.
How Much Does Floor Heating Cost in Toronto in 2026?
Electric floor heating costs $5 to $20 per square foot in materials and $16 to $30 per square foot installed.
| Item | Range |
|---|---|
| Heating mats and flex rolls | $10 to $12 per sq ft |
| Cable with fixing strips | $5 to $15 per sq ft |
| Cable with uncoupling membrane | $15 to $20 per sq ft |
| Custom mats built to room shape | $15 to $20 per sq ft |
| Electric floor heating, installed | $16 to $30 per sq ft |
| Dedicated circuit, GFCI and thermostat | $400 to $1,200 per zone |
| 100A to 200A panel upgrade, if needed | $2,800 to $5,000 plus ESA permit |
| Hydronic in a new slab | Per project, competitive above roughly 800 sq ft |
Planning ranges for budget purposes, not quotes.
Running cost is smaller than people expect. A 100 square foot floor at 15 watts per square foot draws 1.5 kW at full output and cycles at roughly 30 to 40 percent duty once the tile is warm. On a morning and evening schedule that costs about $12 to $20 a month at the Ontario Energy Board off-peak price near 9.8 cents per kWh, and less again on the ultra low overnight plan at roughly 3.9 cents. Without a schedule and a floor sensor, the same floor can cost three times as much.
Why Do Two Quotes for the Same Bathroom Differ by Half?
Because they describe different jobs, not different margins. One includes the electrical work, the other assumes your electrician handles it. One prices a membrane that protects the tile assembly, the other a bare mat. One assumes the panel has capacity, the other has looked.
What Should Every Floor Heating Quote Include?
Eight lines, pulled out and compared across quotes.
| Line item | What a complete quote states | Gap that costs you later |
|---|---|---|
| Wattage per square foot | The figure, and the reason for it | Cold spots, or a floor that short cycles |
| Layout drawing | Included, room specific, before shipping | Cable that does not fit the room |
| Electrical scope | Circuit, GFCI, panel capacity confirmed | Panel upgrade found after demolition |
| ESA notification | Whose scope it is, in writing | Inspection booked with a tile crew waiting |
| Thermostat | Model, floor sensor included | Air sensing control, overheated floor |
| Insulation and underlay | Under-element insulation where needed | Heat lost into a basement slab |
| Warranty | Cable, controls and labour, itemised | One number covering only the cable |
| Voltage | 120V or 240V, matched to the circuit | A mat wired to the wrong supply |
On warranty, ask the supplier to point at the clause covering each part: the cable, the thermostat, and the labour to lift and replace the floor if the element fails. That last clause is the one most often missing.
What Should You Ask Before You Order?
One question: “What would you change about what I have described, and why?” Then stop talking. A supplier who agrees with everything is shipping a box. One who gives you advice you did not want, about the wattage or the floor covering or the wall of windows above the room’s only heat source, has done this before.
Six Red Flags That Should End the Conversation
“You don’t need the ESA for that.” You do. Heating cable must be inspected before it is covered, and skipping it puts the exposure on the homeowner, not on the supplier whose name is not on title.
No CSA mark, or a vague answer about certification. Uncertified product is cheaper and fails inspection. The ESA has documented a fatality from a 120V mat connected to a 240V supply, where the floor reached 62°C.
A price with no layout drawing behind it. A square footage and a number means nobody has looked at your room.
A thermostat with no floor sensor. Air sensing alone either overheats the floor or underheats the room, and it voids the temperature limit most flooring manufacturers require.
A warranty stated in years with no document. Thirty years is a marketing figure until you read what it covers and who honours it in Canada.
A supplier who cannot state the wattage per square foot being quoted. That is the specification, and not knowing it means there is none.
What Permits and Inspections Does Ontario Require?
No building permit for electric floor heating on its own, but an ESA notification and an inspection before the system is covered, filed by the licensed electrical contractor. Hydronic work with a boiler brings in TSSA on the gas side and usually a plumbing permit. Structural changes, a new bathroom or a finished basement pull in the Ontario Building Code. In a condo, the board and the declaration decide first, and floor height and sound transmission are the usual sticking points.
Sequence the project backwards from the floor going down: order the system before demolition, get the layout drawing, confirm voltage with the electrician, and book the ESA notification into the schedule.
Outdoors the margin is smaller. Snow melting cable has to be designed in while the base is still open, because nobody lifts interlocking twice. The same holds for heated walkways and roof de-icing. If any of that is in the plan, price it with the indoor floors rather than a season later.
Where Does Heavenly Heat Fit Against This Checklist?
Run the checks in this guide against Heavenly Heat Inc. and here is what they return.
Accountability. A manufacturer rather than a reseller, designing and building its own electric radiant heating products in the Toronto area and shipping Canada wide from 207 Edgeley Blvd in Vaughan. One company owns the product, the layout and the warranty.
Specification before shipping. Free layout drawings and quotes, with the technical team confirming wattage and voltage before the order goes out. Easy Mat and Flex Rolls run 12 to 15 watts per square foot in 120V or 240V, Easy Wire handles irregular layouts, and custom mats are built to an exact room shape.
Built for this climate. Canadian made and engineered for the freeze thaw cycle, with a published warranty of up to 30 years on underfloor heating and a stated 20 to 30 percent lower energy use than baseboard heaters.
One supplier across the property. Floor heating indoors, plus snow melting for driveways and walkways, roof de-icing and pipe tracing outside, so the whole house runs on one system and one warranty.
Start With a Layout, Not a Price
Most of the guesswork disappears the moment somebody draws your room. A layout settles the wattage, the mat sizes that fit around the vanity, the circuit your electrician pulls and what the job actually costs. Heavenly Heat draws it before price comes up, so book a consultation or call 1-877-523-5667 with your room dimensions, floor type and panel location, and the drawing comes back with the wattage specified for your space.
Common Questions From Toronto Homeowners
What is the best floor heating system for a Canadian home?
For an existing home, an electric mat or cable under tile, because it installs in a day and needs no mechanical room. For new construction with a slab being poured, price hydronic against electric, since water carries roughly 3,500 times more energy than air and pays off over large areas.
Do electric heated floors use a lot of electricity?
No. A typical bathroom floor on a schedule costs $12 to $20 a month over a Toronto winter. Costs climb only when the system runs without a schedule or a floor sensor.
Do I need a permit for floor heating in Ontario?
Not a building permit for electric floor heating alone, but the ESA must be notified and the system inspected before tile or concrete covers it. Hydronic work with a gas boiler adds TSSA and usually a plumbing permit.
What wattage per square foot should my floor be?
Twelve to fifteen watts per square foot for comfort heat in a residential room. If the floor is the only heat source, that figure should come from a heat-loss calculation rather than a rule of thumb.
Which floor coverings work over radiant heat?
Tile and stone are best. Engineered hardwood works when the manufacturer approves it and floor temperatures are capped, usually near 27°C. Laminate and vinyl work with the right underlay. Carpets work when the carpet and underpad have low enough thermal resistance. Solid hardwood is the one to avoid, because seasonal movement shows up as gaps.
What is the lifespan of underfloor heating?
The cable usually outlasts the floor above it, with warranties on quality systems running 20 to 30 years. Thermostats are the wear item and the one component designed for replacement.
