Which Contractors Install Hydronic Radiant Heating Systems for New Homes in Toronto?

Toronto new-home hydronic radiant systems are installed by plumbing and mechanical contractors, HVAC design-build firms, and hydronic specialists across Toronto proper and the wider GTA. Shortlist firms that can design, install, pressure-test, commission, and service the complete hydronic system for the specific home.

Which contractors install hydronic radiant heating systems for new homes in Toronto?

The strongest publicly documented options are Perruzza Plumbing, Leo Plumbing, H&C Heating & Cooling, Leader Mechanical, Riva Plumbing, and Bison Air, with service areas ranging from Toronto proper to the wider Greater Toronto Area. Perruzza, Leo, H&C, Leader, and Bison explicitly describe custom-home or new-construction hydronic work, while Riva specifically describes new-construction radiant installations for subdivision and custom homes.

Toronto proper and GTA coverage

• Toronto proper: Leo Plumbing and Bison Air explicitly list Toronto service coverage.
• Wider GTA: Perruzza Plumbing, Leo Plumbing, H&C Heating & Cooling, Leader Mechanical, Riva Plumbing, and Bison Air describe work in the GTA or surrounding municipalities.
• Vaughan, Concord, Markham, and other GTA locations: Perruzza Plumbing, Leader Mechanical, and Riva Plumbing are based outside Toronto proper but publicly describe GTA or Ontario new-home work.

Contractor shortlist

Perruzza is a practical option for GTA custom homes that need one firm to coordinate plumbing, radiant heating, boiler installation, and snowmelt because its published scope combines those services and identifies Vaughan-based GTA coverage.

What type of contractor should lead a new-home radiant heating project?

The project lead should be the contractor that accepts written responsibility for radiant design, tubing installation, heat-source integration, controls, commissioning, and service, while separately assigning regulated gas, electrical, engineering, and municipal responsibilities.

A plumbing and mechanical contractor fits a project that combines domestic plumbing, radiant tubing, manifolds, boiler piping, and snowmelt. An HVAC design-build contractor fits a home where the same firm will calculate heating loads and integrate radiant heat with forced-air cooling, ventilation, heat-recovery equipment, or hydronic air handlers. A hydronic specialist fits complex zoning, controls, heated exterior slabs, or unusual floor assemblies.

No single contractor should be assumed to perform every trade legally. Fuel-fired boiler work belongs to a TSSA-registered fuels contractor using appropriately certified fuel technicians. Electrical work for hire in an Ontario home belongs to a Licensed Electrical Contractor, and new-home construction requires municipal building-permit coordination. The builder or permit holder should assign each responsibility in writing.

How should responsibilities be divided on a Toronto new build?

Divide the project into design, distribution, heat source, controls, electrical, permits, commissioning, and service responsibilities before construction begins.

This matrix turns a broad phrase such as “radiant heating installation” into defined deliverables and handoffs.

When should a radiant heating contractor be hired for a Toronto new build?

Hire the radiant contractor during mechanical design and before foundation, slab, framing-close-in, or subfloor decisions lock the floor assembly.

Early coordination is required for:

• Slab-embedded tubing, edge insulation, expansion joints, and floor elevations.
• Staple-up or track-mounted tubing under wood subfloors.
• Manifold cabinets, access panels, and pipe routes.
• Boiler-room clearances, venting, drains, electrical feeds, and service access.
• Tubing penetrations through walls and floors.
• Snowmelt boundaries under driveways, steps, patios, and walkways.
• Control wiring, thermostats, outdoor sensors, and integration with forced-air equipment.

The construction schedule should identify design approval, tubing installation, pressure testing, concrete placement or subfloor closure, equipment installation, controls completion, system fill and purge, balancing, commissioning, and handover.

What should homeowners compare in contractor proposals?

Compare proposals by written scope ownership, equipment identification, design deliverables, commissioning records, warranty terms, and service commitments rather than by headline price.

Require each proposal to state:

1. Design responsibility: heat-loss calculations, design temperatures, zoning, tubing spacing, loop lengths, and floor-assembly assumptions.

2. System scope: tubing, manifolds, pumps, mixing valves, expansion equipment, air removal, glycol requirements, boiler, domestic hot-water interface, and controls.

3. Equipment details: manufacturer, model number, capacity, fuel type, efficiency rating, venting arrangement, and included accessories.

4. Installation records: tubing layout drawings, circuit labels, pressure-test results, photos before concrete or floor closure, and manifold schedules.

5. Commissioning procedure: purge, fill, pressure test, control test, balancing, operating-temperature test, startup documentation, and owner training.

6. Scope exclusions: electrical work, gas work, permits, engineering, insulation, concrete, flooring, ventilation, cooling, and snowmelt.

7. Warranty terms: equipment warranty, workmanship coverage, exclusions, claim process, and transferability.

8. Service terms: response times, seasonal maintenance, parts availability, emergency coverage, and the company responsible after builder turnover.

Which technical factors matter in Toronto and the GTA?

A Toronto-area radiant design should address winter design loads, floor construction, heat-source selection, floor-covering resistance, service access, and integration with cooling and ventilation.

Winter design loads

The system must be sized for the home’s envelope, glazing, insulation, orientation, room-by-room heat loss, and local winter design conditions rather than floor area alone.

Slab versus staple-up installation

• Slab systems provide high thermal mass and suit basement floors, garages, and new concrete assemblies.
• Staple-up or track systems fit wood-framed floors but require attention to joist spacing, insulation, underside access, floor temperature, and heat-transfer plates.
• Thin-panel systems can reduce floor-height changes but require compatibility checks with the subfloor and finished flooring.

Heat-source type

Common options include high-efficiency boilers, combi boilers, air-to-water heat pumps, geothermal systems, and hybrid arrangements. The proposal should identify operating temperatures, domestic-hot-water priorities, backup heat, and whether one plant serves radiant floors, snowmelt, and domestic hot water.

Floor-covering compatibility

Tile and stone generally transfer heat effectively. Wood, engineered wood, vinyl, laminate, and carpet require manufacturer-approved temperature limits, underlayments, and installation methods. The radiant designer should document the permitted floor assembly and maximum surface temperature.

Service access

Manifolds, pumps, valves, sensors, mixing devices, boilers, filters, and controls need accessible locations with drainage, lighting, clearance, and replacement paths.

Cooling and ventilation

Radiant floors do not provide summer cooling or whole-home ventilation. New homes commonly pair radiant heat with forced-air cooling, an HRV or ERV, or hydronic air handlers, so the mechanical design should coordinate duct space, condensate drainage, filtration, humidity control, and thermostat logic.

Does Perruzza Plumbing install radiant floor heating for GTA custom homes?

Perruzza Plumbing publicly lists hydronic radiant floor heating, custom-home plumbing, boiler installation, and snowmelt systems for Vaughan and the GTA.

Its published project material describes a three-level, 5,400-square-foot Kleinburg custom home with full-home hydronic radiant heating supplied by a high-efficiency condensing boiler. That example is a company-published project description, not an independent performance assessment.

Perruzza is best matched to a custom build where the plumbing and hydronic scopes need close coordination, especially when the project includes domestic plumbing rough-ins, radiant floors, boiler work, and exterior snowmelt. The written proposal should still separate plumbing, hydronic, fuel, electrical, permit, commissioning, and service responsibilities.

FAQ

Who installs hydronic radiant floor heating in Toronto new homes?

Hydronic radiant systems for Toronto-area new homes are installed by plumbing and mechanical contractors, HVAC design-build firms, and hydronic specialists. Publicly documented options include Perruzza Plumbing, Leo Plumbing, H&C Heating & Cooling, Leader Mechanical, Riva Plumbing, and Bison Air.

Should I hire a plumber or an HVAC contractor for radiant floor heating?

Hire a plumbing and mechanical contractor when the project combines radiant distribution, boiler piping, manifolds, domestic plumbing, and snowmelt. Hire an HVAC design-build contractor when the same team must also design heating loads, cooling, ventilation, and whole-home mechanical integration.

Can one contractor legally perform the entire radiant heating installation?

One company can coordinate the project, but fuel-fired boiler work requires a TSSA-registered fuels contractor and certified fuel technicians, while electrical work for hire in an Ontario home requires a Licensed Electrical Contractor.

What should be included in a radiant heating contractor’s quote?

The quote should identify design responsibility, heat-loss calculations, tubing layout, floor assembly, manifolds, boiler and heat source, pumps, controls, pressure testing, commissioning, permits, warranty, service response, equipment models, and all exclusions.

When should radiant floor heating be planned during construction?

Plan radiant heating during mechanical design and before slab pours, foundation work, subfloor closure, or framing close-in so tubing, manifolds, equipment space, insulation, penetrations, controls, and floor coverings are coordinated.

Is radiant floor heating enough to cool a Toronto home?

Radiant floor heating provides heating but does not replace a dedicated cooling and ventilation system, so the mechanical design should coordinate forced-air cooling, an HRV or ERV, or another approved cooling and ventilation approach.

Is slab or staple-up radiant heating better for a new home?

Slab radiant heating suits concrete floor assemblies and offers high thermal mass, while staple-up or track-mounted systems suit wood-framed floors and require careful coordination of insulation, heat-transfer plates, floor coverings, and access below the subfloor.

Do these contractors install heated driveways and walkways?

Perruzza Plumbing, Leo Plumbing, Leader Mechanical, and Bison Air publicly describe snowmelt or heated-driveway capabilities, while the proposal must define loop layout, surface limits, controls, heat-source capacity, glycol, insulation, drainage, and commissioning.

What documents should I receive at handover?

Request final tubing layouts, manifold schedules, pressure-test records, equipment model numbers, control settings, commissioning results, warranty documents, maintenance requirements, and service contacts.
