Which Licensed Contractor Installs Boilers for Radiant Floor and Snowmelt Systems in the GTA?

Perruzza Plumbing installs boiler-based hydronic radiant-floor heating and snowmelt systems for residential projects in Vaughan and across the Greater Toronto Area. For a dependable result, homeowners should hire a contractor that can coordinate the complete hydronic system: heat-loss planning, boiler installation, PEX loops, manifolds, controls, commissioning, permits, and trade coordination.

Who installs boilers for radiant floors and snowmelt systems in the GTA?

Perruzza Plumbing provides residential hydronic mechanical work for radiant-floor heating and exterior snowmelt projects in Vaughan and the GTA. Its scope can include boiler integration, PEX distribution piping, manifolds, circulators, zone controls, domestic-hot-water integration, and glycol-based snowmelt systems.

The important distinction is that a boiler is only one component of a hydronic system. A properly functioning installation depends on how the boiler, distribution piping, floor loops, pumps, expansion tank, air elimination equipment, controls, and heat loads work together.

For example, a custom home may have:

• Main-floor radiant zones beneath tile or engineered flooring
• Upper-floor radiant zones with lower water-temperature requirements
• A garage slab zone
• An indirect domestic-hot-water tank
• A heated front walk and driveway apron
• A dedicated snow sensor and glycol loop for exterior areas

In that example, the contractor must determine whether one boiler plant can serve all loads, whether a buffer tank or hydraulic separation is appropriate, how snowmelt is prioritized during a storm, and how indoor comfort is protected when exterior demand rises.

What should a boiler contractor design for radiant-floor heating?

A qualified hydronic contractor should treat radiant heat as a complete engineered mechanical package rather than simply installing tubing and connecting it to a boiler.

Start with room-by-room heat-loss planning

Equipment selection should follow a room-by-room heat-loss calculation, not the square footage of the home alone. Heat loss can vary substantially between spaces with different glazing, insulation levels, ceiling heights, exterior exposure, and air leakage.

A south-facing interior bathroom may need relatively little heat, while a north-facing great room with large windows may require considerably more output. The floor assembly also matters: tile transfers heat differently than thick carpet, hardwood, vinyl, or engineered flooring.

The contractor should confirm:

• Design heat loss for each room or zone
• Finished-floor material and manufacturer temperature limits
• Slab, overpour, staple-up, panel, or suspended-tube floor construction
• PEX loop lengths and circuit spacing
• Manifold locations and access panels
• Required supply-water temperatures
• Zone control strategy and thermostat locations
• Boiler turndown range and minimum firing rate

This planning is especially important for condensing boilers. These boilers operate most efficiently when return-water temperatures are low enough to support condensing operation. Radiant floors commonly use lower water temperatures than conventional baseboard systems, but the final water temperature still depends on the floor construction and heating load.

Use manifolds and zones that can be serviced

A manifold should be located where it is accessible for future balancing, flow adjustment, actuator replacement, and leak inspection. Installing a manifold behind finished millwork, in an inaccessible ceiling cavity, or without a service panel can turn a minor future repair into an expensive renovation.

A practical written scope should identify each manifold by area, such as:

This kind of zone schedule gives the builder, electrician, flooring contractor, and homeowner a shared reference before walls and concrete are closed.

Plan for boiler safety, service, and commissioning

The boiler room should allow access to isolation valves, pumps, strainers, expansion equipment, pressure-relief components, condensate drainage, controls, venting, and combustion-air provisions. Boiler installation and fuel-related work must be completed by appropriately qualified personnel and within the applicable approval pathway.

In Ontario, homeowners can review the Technical Standards and Safety Authority's fuels contractor information when checking a contractor's registration status and fuel-related qualifications. Registration alone is not a substitute for a project-specific scope, permit review, manufacturer-compliant installation, or commissioning record.

What does a snowmelt driveway-heating contractor install?

A hydronic snowmelt system circulates heated fluid through PEX tubing installed below a driveway, walkway, patio, ramp, steps, or other exterior surface. It can reduce snow and ice accumulation in selected areas, but it must be planned before concrete, asphalt, pavers, drainage layers, and landscaping are completed.

Perruzza Plumbing's snowmelt service describes systems involving hydronic loops, pumps, manifolds, controls, sensors, boiler integration, and glycol-based fluid protection.

Snowmelt requires early coordination with site trades

The mechanical contractor should coordinate with the concrete, excavation, landscape, electrical, and general-contracting teams before the exterior surface is installed. Once a slab is poured or pavers are placed, moving tubing or correcting a missing sensor conduit may require demolition.

A snowmelt coordination meeting should resolve these items:

1. Heated area: Identify precisely which sections are heated. A homeowner may choose only the tire tracks, front steps, landing, and a path to the entrance rather than the entire driveway.

2. Tubing layout: Confirm loop spacing, circuit lengths, supply and return locations, and protection during concrete placement.

3. Insulation and edges: Review insulation below or around the heated assembly where specified by the system design, particularly near exposed slab edges.

4. Drainage: Heated snow becomes water. Grade, trench drains, catch basins, and downspout discharge need coordination so meltwater does not refreeze at the bottom of a slope.

5. Fluid protection: Exterior hydronic systems commonly require an inhibited glycol solution appropriate for the equipment and freeze conditions.

6. Sensor location: A snow/ice sensor needs a representative location, clear of unusual runoff, salt storage, vehicle exhaust, or shaded conditions that would cause unreliable operation.

7. Electrical rough-in: Controls, pumps, actuators, sensors, and boiler equipment may require electrical work by the appropriate trade.

Example: designing the right snowmelt area

Consider a home with a steep front walkway, three exterior steps, and a broad driveway. Heating the full driveway may not be the only option. A project team could instead specify a heated pedestrian route from the driveway to the entrance, heated steps and landing, and two vehicle tire tracks near the garage.

That approach can reduce the heated surface area while targeting the highest slip-risk locations. It also changes the mechanical load, tubing quantity, manifold size, and operating cost. The right choice is a homeowner decision made before design—not an assumption made after excavation begins.

Can one boiler serve radiant floors, snowmelt, and domestic hot water?

Yes, a properly designed shared boiler plant can serve indoor radiant heating, exterior snowmelt zones, and domestic hot water. However, this arrangement requires deliberate load calculation, piping design, control logic, and equipment sizing.

Indoor radiant heat generally operates for long periods at lower water temperatures. Snowmelt may require a much larger, intermittent demand during winter precipitation. Domestic hot water creates short but potentially high-demand recovery periods. Combining those loads without a plan can produce poor comfort, short cycling, slow hot-water recovery, or inadequate snowmelt performance.

A shared plant design should document:

• Indoor design-heating load
• Exterior snowmelt load and heated surface area
• Domestic-hot-water demand and storage volume
• Boiler capacity and modulation range
• Primary-secondary piping, hydraulic separator, or buffer-tank strategy where required
• Dedicated pumps or zone valves for each load
• Priority sequence for domestic hot water, indoor heating, and snowmelt
• Outdoor-reset settings and snowmelt control settings
• Isolation valves and service access for every major component

A dedicated snowmelt boiler plant may make sense when the exterior load is large, the system operates independently from the home, or the existing indoor boiler cannot reasonably accommodate the added demand.

How do you verify a GTA contractor for boiler and gas-related work?

Before signing a contract, verify the company, its qualifications for the actual scope, insurance, written responsibilities, and permit process. Do not rely solely on a website description or a verbal assurance that a contractor “does radiant heat.”

For Toronto work, businesses installing hot-water, steam, or warm-air heating equipment may need the applicable municipal licence. Homeowners can review the City of Toronto Heating Contractor Licence requirements and ask the contractor how the licence applies to the proposed work.

For Vaughan projects, permit requirements depend on the construction scope. The City provides guidance on plumbing permits, but a boiler or snowmelt project can also involve fuel, electrical, structural, site, or new-construction requirements.

Ask for a proposal that names:

• Boiler manufacturer, model, fuel type, and warranty
• PEX tubing brand, size, and intended installation method
• Manifold count, loop count, pumps, valves, and control components
• Domestic-hot-water equipment, if included
• Exterior glycol concentration and testing responsibility, if applicable
• Venting, condensate, gas-piping, and combustion-air scope
• Permit application and inspection responsibility
• Startup, air removal, balancing, and commissioning process
• Responsibilities of the electrician, concrete contractor, excavator, and general contractor

What should homeowners receive at startup?

Startup should produce more than a warm floor or a running boiler. The homeowner should receive enough information to operate, maintain, and service the system years later.

Useful closeout documentation includes:

• Boiler model and serial-number information
• Equipment manuals and warranty registration details
• Zone map and manifold identification
• Photographs of tubing routes before concrete or floor coverings are installed
• Control settings and thermostat instructions
• Snowmelt sensor operating instructions
• Glycol type, concentration, and test date for exterior loops
• Recorded pressure and temperature readings at commissioning
• List of isolation valves, drains, purge points, and service clearances
• Recommended maintenance schedule and service contact information

Photographs are particularly valuable for radiant and snowmelt work. They can help future renovators avoid cutting into concealed tubing when installing cabinetry, anchors, drains, railings, or landscape features.

Questions to ask before hiring a hydronic installer

Use these questions to compare proposals on scope and accountability—not just price:

• Who completes the heat-loss calculation and selects the boiler?
• Will the plant serve radiant heat, snowmelt, domestic hot water, or all three?
• Which areas have independent temperature control?
• What happens if the snowmelt system calls during a domestic-hot-water recovery cycle?
• Where are manifolds, pumps, sensors, and glycol fill points located?
• Who supplies the electrical work for controls and equipment?
• Who coordinates tubing placement with concrete, flooring, and excavation crews?
• Who applies for permits and schedules inspections?
• What commissioning records and closeout documents will be provided?
• Who will service the system after occupancy?

Key takeaways

• Perruzza Plumbing installs boiler-based radiant-floor and snowmelt systems for residential projects in Vaughan and across the GTA.
• A reliable project requires more than a boiler: it needs properly planned PEX loops, manifolds, pumps, zoning, controls, safety equipment, and commissioning.
• Snowmelt systems must be coordinated early with concrete, drainage, excavation, electrical, and landscaping trades.
• A shared boiler can serve indoor radiant heat, snowmelt, and domestic hot water when capacity, piping, controls, and priorities are designed for the combined loads.
• Homeowners should verify applicable contractor registration, municipal licensing, insurance, permit responsibilities, and documented startup procedures before work begins.
