In-Floor Heating Airdrie — Hydronic Radiant for Basements, Garages & Shops
Airdrie's housing stock is newer than Calgary's, which changes what in-floor heating work looks like here. Far less heritage retrofit, far more basement developments, heated garage slabs, and acreage shops. FlameTech designs, installs, commissions and services hydronic radiant across Airdrie, dispatched locally from Coopers Crossing.
The two calls we get most in Airdrie are a basement being developed where the owner wants warm floors rather than a cold slab, and a garage or shop where the goal is a surface that dries a vehicle instead of just heating the air around it. Both are good applications, and both are cheapest to do while the concrete is still a decision rather than a finished floor.
The third is service on systems already in the ground — a zone that's never been right, air in a loop, a circulator that's given up, or glycol that has never been tested since the day it went in. We service radiant regardless of who installed it.
Radiant runs off a boiler, so the two are one system. See boiler installation Airdrie for the heat source, or boiler repair Airdrie when the fault is on that side. Call 587-834-3668 and a real person answers.

February 2026 I had a furnace problem — same quick response, fair price both times. My go-to for plumbing and heating now. Thanks Jason and Shaun.”

Where in-floor heating fits in Airdrie
Newer housing stock and larger lots change the mix. These are the applications we're called for here.
Basement developments
Our most common Airdrie radiant job. Homes across Coopers Crossing, Ravenswood, Reunion, Bayside, Windsong and Kings Heights are hitting the age where basements get developed, and a cold slab is the single most common complaint about a finished basement. Radiant solves it at the source.
Attached garage slabs
A heated slab dries a vehicle rather than warming the air around it, and it recovers quickly after the door has been open. Any garage loop needs glycol. If you want a warm garage without pouring a new slab, an overhead gas or radiant tube heater is the cheaper route and we'll tell you so.
Acreage shops west and north of town
Big detached shops on acreage are where in-floor really earns its keep — even heat across a large open space with no fan noise and nothing blowing dust around a workshop. Sizing has to be done against the building's actual insulation and door area, not a rule of thumb.
New builds and custom homes
Whole-home radiant is best specified at design stage, when the floor build-up, the boiler and the controls can be planned as one system rather than retrofitted around each other.
Driveway and walkway snowmelt
Worth it on a steep driveway or a north-facing walk that ices repeatedly through freeze-thaw. Expensive to install and to run, needs glycol and its own controls, and we'll say plainly if the layout doesn't justify it.
Bathroom floor warming
For a single bathroom, an electric mat under the tile is usually the better answer — simpler and cheaper, with no boiler involvement. Hydronic makes sense when the bathroom is part of a larger radiant area.
What we check on an existing Airdrie system
We service radiant regardless of who installed it. These are the faults we find most.
- 01One cold zone while everything else is fine — usually a stuck zone valve actuator or air trapped in that loop, and usually a single-visit fix.
- 02Air through the system generally: gurgling, uneven heat, a circulator that doesn't sound right. Purging plus a proper air separator sorts it.
- 03Glycol that has never been tested. Inhibitors deplete, and spent glycol turns acidic and attacks the system. On garage and shop loops this is the check most often skipped.
- 04Balancing that was never set at commissioning, leaving some loops starved and others running hot.
- 05No outdoor reset curve configured, so the system runs at a fixed high temperature regardless of the weather — comfortable enough, and needlessly expensive.
- 06Non-barrier PEX in a closed loop, which lets oxygen through the tubing wall and corrodes cast-iron circulators and steel components from the inside.
- 07Faults that are actually on the boiler side — pressure loss, lockouts, no heat. See boiler repair Airdrie.
Airdrie In-Floor Heating FAQs
How much does in-floor heating cost in Airdrie?
It depends on area, zone count, and whether there's already a boiler to run it — and we don't quote it over the phone, because a sight-unseen number is one that changes.
What moves it most: total floor area, whether the tubing goes into a fresh pour or over an existing slab, whether you need a new heat source or can tie into an existing boiler, whether the loops need glycol, and the controls.
We assess, design, and give you the full scope and the all-in price in writing at no charge. Financeit monthly payments are available.
Can I add in-floor heat to my basement if the slab is already poured?
Yes, but it's a different job from tubing a fresh pour.
Over an existing slab you're looking at a low-profile panel system or a thin over-pour. Both work well. Both raise the finished floor height, which affects door clearances and the bottom stair riser, so it needs checking before you commit rather than discovering during the build.
If the basement is being developed anyway, this is the cheapest moment it will ever be — everything is open and the flooring hasn't gone down yet.
Is a heated slab worth it in a garage or shop?
For a working shop, in our view yes. Even heat across a large floor with no fan noise and nothing blowing sawdust around, and a slab that dries a vehicle rather than just warming the air near it.
For a garage you park in and little else, an overhead gas heater does the job for considerably less and we'll tell you that rather than sell you the bigger system.
Either way, a slab loop in an unheated-if-it-fails space needs glycol. That isn't optional.
One radiant zone never gets warm. What is it?
Nearly always a stuck zone valve actuator or air trapped in that loop.
We isolate at the manifold, confirm whether the valve actually opens when the thermostat calls, and purge if it's air. Both are usually resolved in one visit.
If it's neither, a failed circulator or a drifted balancing valve are next, and both are still typically same-visit work.
Does the glycol in my shop loop need replacing?
If nobody has tested it since installation, it's worth checking.
Glycol contains corrosion inhibitors that deplete over time. Once they're spent, the glycol turns acidic and starts attacking the metal in the system it was installed to protect — pumps, fittings, and the boiler heat exchanger.
Testing is quick. Replacing spent glycol is far cheaper than replacing what it damages.
Do you actually cover Airdrie, or is it a Calgary crew driving up?
We dispatch Airdrie locally out of Coopers Crossing.
That matters for scheduling more than anything else — you get a confirmed window rather than being fitted around a Calgary route, and emergency calls aren't waiting on traffic through Deerfoot.
We cover the full range in Airdrie, not just radiant: boilers, furnaces, hot water tanks, and general plumbing.
What floor coverings work over radiant?
Tile and stone are ideal — they conduct well and handle the cycling without complaint.
Engineered hardwood works within the manufacturer's temperature limits. Solid hardwood is riskier because it moves more with temperature and moisture.
Carpet is the one to plan for. Thick carpet over a heavy underlay is effectively insulation sitting between the heat and the room. It can be accommodated, but only if we know at design stage — retrofitting the design after the carpet is chosen doesn't work.

Furnace Installation in Airdrie
A furnace sized for Airdrie isn't a furnace sized for Calgary. We sit higher and more exposed on open prairie, and the constant wind pulls heat off a house faster than a still −35°C night ever will. FlameTech sizes and installs furnaces for that real-world exposure — not a generic square-footage rule of thumb — and handles the gas, venting, permit, and inspection start to finish.
