Why it is different
Patio heating is not outdoor HVAC
Indoor heating works by warming air and keeping it in the room. A patio has no room. Whatever you do to the air outside, it moves away — so heating a patio by heating its air is not a design decision, it is a losing one.
Outdoor heating works instead by radiation: infrared travels from the heater to the first solid thing in its path and warms that. On a patio those things are the guests, their table, the chairs and the floor. The air in between stays more or less as it was, which is exactly why the approach works with no walls in place.
The practical consequence is that a patio heating design is about aim and zones, not about capacity. Where are the seats? Which sections are used on a quiet Tuesday? Which way does the wind come across the terrace? Get those right and a patio stays comfortable well past the point at which the season would normally end.
What matters most for Patio 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.
What we work out before specifying anything
- Where guests actually sit, and which sections are used when
- Whether the space is open, covered, or partly enclosed
- Prevailing wind across the terrace and any shelter already there
- Mounting options — overhead, wall, or freestanding on poles
- Gas or electric, and what the supply can realistically carry
- Zone switching so empty sections are not being heated
- Clearances, venting class and combustion air where enclosure exists
- How the system will be operated by staff night to night
Where we install
Spaces we heat
Each of these asks a different question of the design — mostly about how enclosed the space is.
Restaurants & bars
Seating-density zones rather than evenly spaced units, so the sections you fill first are the sections that are warm. Switching by zone lets staff heat only what is in use.
Outdoor dining & terraces
Fully open-air seating, where radiant aim matters most. Heat is directed at tables and guests rather than at the gaps between them.
Residential patios
Back gardens, decks and porches. Usually a smaller, simpler layout — often electric where a gas run would be disproportionate.
Semi-outdoor & covered areas
Roofs, awnings and retractable walls hold heat far better than open decks, which helps efficiency but concentrates clearance, venting and combustion-air questions. These need engineering, not guesswork.
Hotels & hospitality
Rooftop terraces, courtyards and entrances, where the heating has to look considered as well as work.
Entrances & waiting areas
Queues, doorways and pick-up points, where people are stationary for a few minutes and directed heat is felt immediately.
Gas or electric?
Gas and electric patio heating compared
Both are used regularly here. The space usually decides which, before preference does.
| Gas infrared | Electric infrared | |
|---|---|---|
| Typical use | Larger commercial patios and terraces | Residential and smaller commercial areas |
| Installation | Gas run, licensed connection, venting where enclosed | Electrical supply and capacity |
| Open, exposed spaces | Strong performer on open terraces | Works well, more sensitive to wind |
| Covered or enclosed areas | Venting class and combustion air become critical | Simpler where enclosure is significant |
| Mounting | Overhead, wall, or pole-mounted | Overhead, wall, or flush into structure |
| Appearance | Larger units, more visible | Slimmer profiles available |
| Zone control | Zone panels and remote control available | Straightforward switching and dimming |

Design, licensed installation, controls and seasonal commissioning.
Patio walkthrough & heat design
We walk the terrace, note the seating, the shelter and the wind, and produce a zone layout — heater positions and aim, not an evenly spaced grid.
Request a consultation →Gas infrared supply & install
Commercial-grade gas radiant heaters, installed with licensed gas rough-in, correct venting class and clearances.
Request a consultation →Electric infrared supply & install
Electric radiant for residential patios, covered areas and spaces where a gas run is not proportionate.
Request a consultation →Zone controls & switching
Zone panels, remotes and transformers so staff can heat the sections in use and leave the rest off.
Request a consultation →Mounting, poles & brackets
Wall arms, ceiling kits and pole mounts specified for the structure and the heater series being installed.
Request a consultation →Seasonal commissioning & service
Pre-season checks and end-of-season servicing so the patio is ready before the first cold week, not during it.
Request a consultation →Zone it
The biggest lever there is
Heat the occupied sections, aim the units correctly, avoid chronic oversizing, and close unused retractable walls when it makes sense. Efficiency on a patio is mostly design and operation — not a single number on a specification sheet.
Why Toronto Air Systems
Why hospitality operators use us
Local crews, licensed workmanship, and recommendations built around how Toronto buildings actually heat and cool — not generic scripts.
Zone maps, not evenly spaced guesswork
Layouts are built from seating density, shelter and wind. Evenly spacing heaters across a terrace reliably produces warm gaps and cold tables.
We are honest about what outdoor heat can do
Radiant heating extends your season substantially. It will not hold an open patio at indoor temperature in deep winter, and we would rather say so at quoting stage.
Enclosure handled properly
Covered and semi-enclosed areas raise venting class, combustion air and condensation questions. These are engineered together rather than treated as an open patio with a roof.
Commissioned before the season
Pre-season checks mean the first cold Friday is not when you discover a burner will not light.
How it works
How a patio heating install runs
From first call to commissioned equipment, you always know the next step, the timeline, and what is included.
01
Patio walkthrough
We visit the space, note the seating plan, shelter, wind direction and how the patio is used across the week.
02
Zone layout & specification
Heater positions, aim and zones proposed, with gas or electric decided against the space and the supply.

FAQ
Patio heater FAQ — Toronto & GTA
How is patio heating different from indoor heating?
Indoor heating warms air and depends on the room holding it. A patio has no room, so the air simply moves away. Outdoor heating works by infrared instead — it warms the guests, tables and floor directly, which is why it works with no walls in place.
How many heaters does my patio need?
It depends on the square footage, the mounting height, the wind and how densely the seating is laid out. We design zones rather than selling a heater count — undersized layouts leave cold corners, and oversized ones waste gas and overheat staff lanes.
What mounting height works best?
Follow the manufacturer listing for the model being installed, which gives a defined range above seated guests along with the required clearances. Too high and the comfort drops off; too low and you have a clearance problem. It is set per model and per space, not by a single figure.
Gas or electric — which should I choose?
Larger commercial terraces usually favour gas; residential patios and smaller or more enclosed areas often favour electric. What decides it in practice is the space, the degree of enclosure and what the gas or electrical supply can carry. We work that out at the walkthrough.
Can you heat a covered or semi-enclosed patio?
Yes, and enclosure actually helps hold heat. But it also concentrates clearances, combustion air and condensation issues, so venting class and gas train have to be engineered together rather than assumed. That is a design question we handle specifically.
Will it keep the patio warm in January?
It will make chosen sections comfortable for guests in outerwear, and it will extend your usable season considerably at both ends. It will not hold an open patio at indoor temperature in deep winter — no outdoor system can, because there is no envelope to hold the heat.
Do you service heaters you did not install?
Yes, provided they are safe and serviceable. We will say clearly if something has been installed in a way that cannot be signed off, and what correcting it involves.
How much does Patio Heaters cost in Toronto?
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.
Do you serve my area in the GTA?
Yes. We are based in North York at 132 Cartwright Ave and regularly serve Toronto, Mississauga, Vaughan, Markham, Scarborough, Etobicoke, Brampton, and nearby communities.
Are your technicians licensed?
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.
Plan your patio heating
A walkthrough gives us the seating, the shelter and the wind — and those decide the layout. Tell us about the space and we will design the zones.
