Radiant tube heaters · Toronto & GTA

Radiant tube heaters for
rooms with high ceilings

A tube heater warms the floor and the people standing on it instead of the air near the roof. That is why warehouses, workshops, garages and bays across the GTA use them — and why they keep working in rooms where the doors are always open.

What it is

What is a tube heater?

A radiant tube heater is a long steel tube, mounted high, with a gas burner at one end. Combustion gases travel the length of the tube and heat it; a polished reflector above the tube directs that heat downward. The tube becomes a line of warmth aimed at the floor.

Nothing is blown around. The heat travels as infrared — the same way you feel the sun through a cold window — and is absorbed by the first solid things it meets: the floor slab, the machinery, the people. Those surfaces then release warmth back into the room slowly.

That single difference is what makes tube heaters suit tall, draughty rooms. A forced-air heater puts its heat into the air, and in a building with a high roof and doors that keep opening, much of that air ends up either at the ceiling or outside. Radiant heat is already in the floor before the air has a chance to take it away.

What matters most for Tube Heaters in the GTA
Right sizing, licensed gas/refrigeration work, and commissioning beat the cheapest sticker price. We verify airflow, safety devices, condensate paths, and controls so your system does not fail the first extreme week of the season. Ask us about dual-fuel, zoning, and rebate-eligible models during your quote.
Where a tube heater is usually the right call
  • Ceilings too high for warm air to reach the people below
  • Doors or bays opening repeatedly through the working day
  • Buildings that are difficult or expensive to seal properly
  • Work that happens in specific bays rather than across the whole floor
  • Spaces where blown air would disturb dust, fumes or finishes
  • Sites that want to heat only the areas in use, shift by shift
  • Rooms where floor-level warmth matters — standing work, vehicle bays
  • Buildings with the roof clearance and gas supply to support one
How it works

From burner to warm floor

Five stages, all of them happening continuously while the heater runs.

Applications

Where tube heaters are used

The common thread is height, air movement, or both.

Warehouses & distribution
High roofs and loading bays that open all day. Radiant heat reaches the floor where picking and packing happen instead of collecting above the racking.
Workshops & vehicle bays
Doors opening for every vehicle. Radiant warmth in the floor slab keeps working through the door cycle, and warms the vehicle and tools as well as the technician.
Light industrial & production
Zoned along working lines so occupied areas are heated and empty ones are not. Useful where blown air would move dust or affect a finishing process.
Garages, depots & storage
Buildings that are hard to seal and rarely worth heating in full. Tube heaters warm the parts people use without conditioning the entire volume.
Agricultural & large sheds
Tall, ventilated buildings where warm air simply leaves. Radiant heat aimed down does not depend on holding onto the air.
Sports halls & large venues
High ceilings and intermittent occupancy, where heating the full volume in advance is wasteful.
Tube heater or unit heater?

Radiant tube vs. forced-air unit heater

Both are gas-fired and both hang from the roof. What they do with the heat is entirely different.

What we do

Tube heater services

Assessment, layout, licensed installation and annual servicing.

Site assessment & zone layout
We measure the building, note the roof clearance, door traffic and where work actually happens, then lay out tube runs and zones to suit it.
Supply & installation
Commercial-grade radiant tube heaters supplied and installed, with gas, venting and electrical completed to code by TSSA-licensed technicians.
Venting & combustion air
Correct venting class, termination and combustion air are engineered as part of the install rather than left to the fitter on the day.
Controls & zoning
Zone switching and controls so occupied bays are heated and empty ones are not — the single biggest running-cost lever on a radiant system.
Servicing & safety checks
Annual servicing covering burner, tube integrity, reflectors, venting and clearances.
Repairs & replacement
Repair of existing radiant systems, and replacement where a tube or burner has reached the end of its life.
Five factors
Decide coverage, not one number
How much area a radiant heater covers depends on its output, the height and angle it is installed at, the type of heater, the air movement in the space, and the shape of the space itself. Change any one and the answer changes. We design zones from those five factors — nobody should be quoting you a coverage figure before they have seen the building.
Why Toronto Air Systems

Why specify a tube heater through us

Local crews, licensed workmanship, and recommendations built around how Toronto buildings actually heat and cool — not generic scripts.

Layout designed from the building
Tube runs, mounting height and aim are set from the survey — roof clearance, working lines, door positions — because coverage is a function of all of them.
Manufacturer listings, not rules of thumb
Mounting heights and clearances come from the listing for the specific model being installed. We do not apply a single figure across different equipment.
TSSA-licensed gas work
Burner, gas train and venting installed and commissioned by licensed technicians, with the paperwork to match.
Zoning treated as part of the design
Being able to heat one bay and not the other four is where the running cost is won, so controls are specified with the heaters rather than added later.

FAQ

Tube heater FAQ — Toronto & GTA

A long steel tube with a gas burner at one end and a reflector above it, mounted high in the building. The tube gets hot and radiates infrared downward, warming the floor, equipment and people directly rather than heating the air.
A conventional heater warms air and relies on that air staying in the room. Radiant heat travels to solid surfaces and is absorbed by them, so it still works in tall spaces and in rooms that lose air through open doors.
They are efficient in the way that matters for this type of building: you can heat the occupied part of a room and leave the rest, and you are not paying to warm air that leaves through a bay door. How much you save depends on the building and how you zone it, so we would rather show you the layout than quote a figure.
That comes from the manufacturer listing for the specific model, which gives a defined range along with the clearances to combustibles. It is not a single number that applies to all radiant heaters, and it is set at design stage against your roof height and what is below the run.
It depends on the output of the unit, the mounting height and angle, the heater type, the air movement in the building and the shape of the space. Those five together decide coverage, which is why we lay out zones after a site visit rather than quoting a radius.
Yes, when installed to the listing. The safety items that matter are clearance to combustibles and stored stock, correct venting and combustion air, and a burner serviced annually. Those are checked at install and at every service.
Usually, provided there is roof clearance for the run, a gas supply that can carry it, and a viable venting route. Those three are exactly what the site assessment checks first.
Cost depends on equipment capacity, brand, duct or piping complexity, electrical/gas upgrades, and whether you repair or replace. We provide written quotes after a site assessment so you can compare options fairly. Call 647 953-4252 for a visit.
Yes. We are based in North York at 132 Cartwright Ave and regularly serve Toronto, Mississauga, Vaughan, Markham, Scarborough, Etobicoke, Brampton, and nearby communities.
Yes. Gas and refrigeration work is performed by TSSA-licensed technicians. We follow Ontario code practice for venting, refrigerant handling, electrical disconnects, and condensate management.
