Hydronic radiant floor heating is a water-based in-floor heating system that circulates warm water through a network of flexible PEX (cross-linked polyethylene) tubing installed within or beneath your floor. As the warm water flows through the tubing, heat radiates upward through the floor surface, warming the room evenly from the bottom up.

Radiant heat warms objects and people directly — not just the air. The result is an even, draft-free warmth that extends from the floor to the ceiling without hot spots or cold zones. In Ontario winters, stepping onto a warm floor makes a profound difference in daily comfort, whether it is a bathroom, kitchen, basement, or garage.
Hydronic radiant floor heating operates at significantly lower water temperatures than traditional radiators or baseboard heaters. Combined with precise zone control — heat only the rooms you use, when you use them — most Ontario homeowners see measurable reductions in their monthly heating costs. When paired with a high-efficiency condensing boiler or an air-to-water heat pump, the system delivers some of the lowest operating costs available for residential heating in Ontario.
Forced-air systems distribute heat by blowing air through ductwork — and along with it, dust, allergens, pet dander, and other airborne particles. A hydronic radiant system has no ducts, no fans, and no air movement. Homeowners with allergies, asthma, or respiratory sensitivities consistently report dramatic improvements in indoor air quality after switching to radiant heat.
There are no vents, no radiators, and no baseboard heaters taking up wall space or making noise. The entire system is concealed beneath your floor. Circulator pumps operate quietly, and there are no blowers or mechanical noise in your living spaces. Your interior design remains completely uncompromised.
Our hydronic radiant systems are compatible with virtually every energy source available in Ontario — natural gas boilers, high-efficiency condensing boilers, air-to-water heat pumps, ground-source geothermal systems, solar thermal energy, and district heating. As energy codes evolve and heat pumps become the standard in Ontario new builds, radiant floors are the optimal delivery system because they perform at the low water temperatures heat pumps produce most efficiently.
Hydronic radiant floor heating is a recognized premium feature in the Ontario real estate market. Buyers in Burlington, Hamilton, the GTA, and Niagara increasingly expect high-performance heating in new or renovated homes. A professionally installed, warranted radiant system is a tangible, documentable upgrade that adds to your home's resale value.
Hydronic radiant floor heating can be installed using one of three different methods:
If you would like more information on how the installation works, call us at 905-538-1661. One of our experts will be glad to walk you through the process and offer a no-obligation estimate.
A hydronic radiant floor heating system comprises three main components: a heat source, a distribution piping system, and controls.
| Feature | Hydronic Radiant Floor Heating | Traditional Forced-Air |
| Heat Distribution | Even, floor-to-ceiling radiant warmth | Uneven; hot air rises, feet stay cold |
| Energy Efficiency | Up to 30% more efficient | Loses heat through ductwork |
| Air Quality | No dust, allergens, or drafts | Circulates dust and allergens |
| Noise Level | Virtually silent operation | Fan/blower noise throughout day |
| Compatibility | Heat pumps, solar, geothermal, boilers | Gas furnace or air handler only |
| System Life | PEX tubing lasts 50+ years | Ducts and furnace require replacement |
| Home Value Impact | Premium upgrade; adds resale value | Standard; no premium value added |
The correct installation method depends on whether your project is new construction, a renovation, or a retrofit. As a certified installation contractor, Canadian In-Floor Radiant Solutions assesses your specific structure, floor assembly, and heating requirements before recommending the right approach. We handle every aspect of the installation — from system design and PEX tubing layout to manifold installation, boiler connection, and zone commissioning.
| Method | Best For | Floor Build-Up | Heat Transfer |
| Slab-on-Grade | New construction, garages, basements | Embedded in slab; none | Excellent — highest efficiency |
| Concrete/Gypsum Overpour | Renovations over existing subfloor | +1.5 inches | Excellent |
| Above-Subfloor Thin Plate | Retrofit where height gain is limited | +0.5 inches | Very Good |
| Suspended (Dry Plate) System | Under wooden subfloor from below | No floor-height change | Good — depends on transfer plates |
This is the most efficient and cost-effective installation method. PEX tubing is attached to reinforcing wire mesh or rigid foam insulation board and secured in place before the concrete slab is poured. The tubing becomes embedded within the slab, which acts as a thermal mass — absorbing, storing, and radiating heat with exceptional efficiency. This is the standard approach for new home construction, garage in-floor heating, and basement slab installations across Ontario.
This is the optimal time to install radiant floor heating. If you are pouring a new concrete slab for any reason — new construction, garage addition, basement renovation — installing PEX tubing at this stage adds minimal cost and delivers lifetime benefits.
PEX tubing is fastened above an existing subfloor, then covered with a lightweight concrete or gypsum cement underlayment approximately 1.5 inches thick. This method is widely used in renovation projects across Burlington, Hamilton, and the GTA where a new concrete slab is not being poured, but maximum radiant efficiency is still required. The overpour creates an excellent thermal mass and allows the same floor-to-ceiling radiant warmth as slab installation.
Tubing is laid between the subfloor and finished floor using thin aluminum heat-transfer plates, adding as little as half an inch to the total floor height. This approach is ideal for renovations where maintaining existing floor heights is important — for example, transitions between rooms, doorframe clearances, or multi-level retrofits. While slightly less efficient than slab methods, the thin-plate system still delivers significant radiant comfort improvement over any forced-air alternative.
PEX tubing and aluminum transfer plates are fastened to the underside of an existing subfloor, accessible from a basement or crawlspace below. This method does not require any disruption to the finished floor above, making it an attractive option for homeowners who want to add radiant heating to an existing space without tearing up their floors. Performance is dependent on the quality of the transfer plates and the insulation applied to the underside of the assembly.
A complete hydronic radiant floor heating installation by Canadian In-Floor Radiant Solutions includes three integrated components — all designed, supplied, and installed by our certified team:
We work with all major heat sources compatible with hydronic systems, including high-efficiency natural gas boilers (Viessmann, NTI), combi-boilers for combined space heating and domestic hot water, and air-to-water heat pumps for homes transitioning to low-carbon heating. We assess your home's heat loss, square footage, and zone layout to specify the correctly sized heat source — preventing both undersizing (insufficient heat) and oversizing (energy waste and short-cycling).
We exclusively use Uponor PEX-a tubing — the industry's highest-quality cross-linked polyethylene, with unmatched flexibility, durability, and a 25-year manufacturer warranty backed by Uponor's Level 2 certification. PEX-a tubing is kink-resistant, freeze-damage tolerant, and engineered to maintain consistent flow characteristics for 50+ years. Loop spacing, tube diameter, and flow rates are calculated to deliver precise, even heat output for every zone.
The manifold is the distribution hub of your system — it directs heated water to each zone and ensures balanced flow throughout. We install fully calibrated manifold systems with individual zone controls, allowing each room or area to be set independently. Smart thermostats and aquastat switches provide precise temperature management, automated scheduling, and — on compatible systems — remote control via smartphone. This level of control is what separates a professionally designed radiant system from an undersized, inefficient installation.
New construction is the ideal time to install a hydronic radiant floor heating system. Radiant is designed into the build from the start — there is no disruption, no floor build-up concerns, and no retrofitting cost. We work alongside your builder during the framing and concrete stages to ensure the system is properly integrated, insulated, and commissioned before occupancy. If you are building a new home in Burlington, Hamilton, the GTA, Niagara, or Ontario's cottage country, contact us during the planning stage for the best outcome and lowest installation cost.
Radiant floor heating can be added during any major renovation — kitchen upgrades, bathroom remodels, basement finishing, home additions, or whole-floor renovations. We assess the existing floor structure to determine the most appropriate installation method, calculate the additional load from an overpour if required, and integrate the new radiant zones with your existing boiler or heat source where possible. We have successfully retrofitted radiant heating in homes across Hamilton, Burlington, and the GTA at all stages of renovation.
A finished basement with radiant floor heating in a concrete slab is one of the most popular upgrades for Ontario homeowners. It transforms a cold, damp-feeling basement into the most comfortable room in the house. PEX tubing is installed in the slab before the pour — or, in renovation projects, beneath a new floating slab or gypsum overpour. Combined with proper subfloor insulation, a basement radiant system delivers exceptional warmth even in Ontario's coldest winters.
Heated garage floors are increasingly popular with Ontario homeowners, car enthusiasts, and workshop users. A hydronic in-floor heating system for a garage eliminates the freeze-thaw damage caused by cold concrete, prevents ice formation at the slab surface, and creates a comfortable working environment year-round. Garage systems are typically slab-on-grade installations — the most efficient and cost-effective installation type. We design and install garage in-floor heating systems throughout the Niagara, Hamilton, Burlington, and GTA service area.
A whole-home hydronic radiant system replaces your existing heating system entirely, eliminating the need for furnaces, ductwork, and forced-air distribution. Each floor or room is independently zoned for precise temperature control. Whole-home installations are most cost-effective in new construction but can also be designed for extensive renovations where complete floor access is available. We conduct a full heat-loss calculation for every whole-home project to ensure the system is properly sized and delivers optimal efficiency.
We install radiant heating systems in commercial buildings, multi-residential developments, and light industrial spaces across Ontario. Radiant is particularly well-suited to high-ceiling commercial spaces where forced air loses significant heat to stratification. Our commercial installations include warehouses, retail spaces, office buildings, and multi-unit residential projects.
The cost of a hydronic radiant floor heating installation in Ontario depends on the size of the area, the installation method, the number of zones, the heat source, and whether the project is new construction or a renovation retrofit. Below are typical installed cost ranges for common applications in the Burlington, Hamilton, and GTA market as of 2025–2026:
| Application | Estimated Installed Cost (Ontario) | Notes |
| Single room / bathroom | $2,500 – $5,500 | Easiest retrofit; minimal disruption |
| Whole-home new construction | $8,000 – $20,000+ | Most cost-effective time to install |
| Basement / concrete slab | $4,000 – $10,000 | Slab-on-grade is ideal for PEX |
| Garage in-floor heat | $3,500 – $8,000 | Popular for workshops & vehicles |
| Full renovation retrofit | $10,000 – $25,000+ | Depends on floor access & size |
These are estimated ranges for fully installed systems including design, PEX tubing, manifolds, controls, and labour. Heat source (boiler or heat pump) costs may be additional depending on your existing equipment. Contact us for a detailed, no-obligation quote specific to your project.
Hydronic radiant floor heating works with most flooring materials, but performance varies. We advise all clients on flooring compatibility during the design phase:
New construction is always the most cost-effective time to install radiant floor heating. During renovation, feasibility depends on three factors we assess at no cost: whether the existing floor structure can support the additional weight of a concrete overpour; whether the underside of the subfloor is accessible from below; and whether there is adequate ceiling height to accommodate an overpour in basement spaces. If any of these are uncertain, contact us for a free site assessment.
Many homeowners start with radiant heating in the areas that matter most — primary bathrooms, kitchen, master bedroom, basement — while keeping their existing forced-air system for other areas. This approach minimises upfront cost and allows you to experience the comfort difference before committing to a full-home installation. Our zoned systems can be expanded over time, and we design every installation with future expansion in mind.
Hydronic radiant floor heating is one of the most environmentally responsible heating options available in Ontario. When paired with a high-efficiency condensing boiler or an air-to-water heat pump, the system delivers exceptional comfort at significantly reduced carbon output. Ontario homeowners may be eligible for energy efficiency rebates through the Canada Greener Homes Grant or Enbridge Home Efficiency Rebate programs when upgrading their heating system. Ask our team about current rebate opportunities during your consultation.
We believe a successful installation starts long before any tubing is laid. Here is how we approach every radiant heating project in Ontario:
One of the most practical advantages of a hydronic radiant heating system is its ability to power outdoor snow melt systems using the same boiler and piping infrastructure. If you are investing in hydronic radiant heating for your home, adding a heated driveway, walkway, or patio snow melt zone is significantly more cost-effective than a standalone installation.
Canadian In-Floor Radiant Solutions designs and installs hydronic snow melt systems for driveways, walkways, parking areas, and commercial spaces throughout Ontario. The system uses the same PEX tubing and glycol/water mixture, circulated through loops installed beneath your driveway or patio surface. Automated sensors detect when snow is falling and activate the system only when needed, minimising operating costs.
Canadian In-Floor Radiant Solutions provides professional hydronic radiant floor heating installation throughout Southern Ontario, including:
Not sure if we service your area? Call us at 905-538-1661 or send us a message — we are happy to discuss your project regardless of location.
Snow melt systems installed by Canadian In-Floor Radiant Solutions operate by circulating a mixture of water and antifreeze through durable PEX tubing installed beneath the surface. The heated fluid melts the snow and ice using a sensor to remove hazards, ensuring your spaces stay clear and dry throughout the season.
We can seamlessly integrate our snow melt systems into an existing in-floor hydronic radiant heat system or install it as a standalone solution. Connect with our expert heat system technicians to evaluate your needs and create a custom solution for your home or business.

Installation time depends on the project scope. A single-zone installation in a new concrete slab typically takes 1–2 days for the tubing and manifold work before the pour. A multi-zone whole-home installation or renovation project may take 1–4 weeks depending on floor access, number of zones, and whether a new heat source is being installed. We provide a detailed project timeline in every written quote.
Installed hydronic radiant floor heating in Ontario typically costs between $1,000 and $1,200 per 100 square feet for standard residential applications, depending on the installation method, number of zones, and heat source. Single-room retrofits start around $2,500–$5,500; whole-home new construction systems range from $8,000 to $20,000 or more. Contact us for a detailed written quote specific to your project and location.
Yes, but performance varies by material. Concrete, porcelain tile, and stone are the best conductors of radiant heat and deliver the highest efficiency. Engineered hardwood and LVP work well when installed within manufacturer temperature limits. Thick carpets and solid hardwood reduce heat transfer and require careful system design. We advise all clients on flooring compatibility as part of our free consultation.
Yes — in fact, hydronic radiant floors and air-to-water heat pumps are an exceptionally well-matched combination. Heat pumps produce water at relatively low temperatures (35–50°C), which is precisely the range at which radiant floor systems operate most efficiently. As Ontario moves toward heat pump adoption under updated energy codes, radiant floors are increasingly the preferred heating delivery system for heat pump installations.
PEX tubing installed in a concrete slab or subfloor has an expected lifespan of 50 years or more — essentially the life of the building. The mechanical components (boiler, pumps, controls) have a typical service life of 15–25 years with annual maintenance. Our Uponor PEX systems carry a 25-year manufacturer's warranty when installed by our Level 2 certified team.
Yes. PEX tubing is durable, leak-resistant, and certified for potable water use. The system operates at water temperatures well below the range that poses any burn risk at the floor surface. There are no exposed heating elements, no combustion at the floor level, and no risk of overheating under normal operating conditions. Our installations are fully inspected and pressure-tested before commissioning.
Yes. Hydronic radiant floor heating is widely recognised as a premium home feature in the Ontario real estate market. A professionally installed, warranted system — particularly in a new build or major renovation — is a documented, tangible upgrade that increases your home's resale value and marketability. Buyers in Burlington, Hamilton, and the GTA are increasingly seeking homes with radiant heating over conventional forced-air systems.
In many cases, yes. If the underside of the subfloor is accessible from a basement or crawlspace, a suspended dry-plate installation can be completed without disturbing the finished floor above. If floor access from above is required (for overpour or slab methods), we minimise disruption and scope the project carefully to limit the area affected.
