Water Heater · Burlington, OntarioWater Heater Repair & Replacement in Burlington
Water heater repair and replacement in Burlington is a short drive for us: the shop is on North Service Road, just off the QEW, so most of the city is a 10-to-20-minute run in normal traffic. A leaking tank is replaced the same day in most cases; a failed thermocouple, gas valve or heating element is repaired for $150–$800, and you get the number before we start.
Water Heater Repair & Replacement in Burlington
Burlington's water heaters sort roughly by neighbourhood age. The 1950s and 60s bungalows and side-splits in Roseland, Shoreacres and Elizabeth Gardens, and along Plains Road in Aldershot, were built with a masonry chimney, and many still run an atmospheric-vent gas tank that drafts up it. Tyandaga, Brant Hills and Pinedale homes from the 1970s usually have the same arrangement with a newer tank. Millcroft, Headon Forest, Orchard and Alton Village — built from the late 1980s through the 2010s — more often have power-vent tanks that exhaust through plastic pipe and need a 120-volt outlet, and a growing number have switched to wall-hung tankless units. The condos along Lakeshore Road downtown are the odd ones out: some suites have their own electric tank, others get hot water from a central boiler the building maintains.
The problem that comes up most in the older neighbourhoods is the orphaned water heater. When a high-efficiency furnace goes in and vents out the side wall, the old tank is left by itself on a chimney that was sized for two appliances. The flue gases cool too quickly in the oversized brick flue, condensation eats the mortar, and on a still, humid day off the lake the tank can spill exhaust back into the basement. The fix is a properly sized aluminum or stainless liner, or a switch to a power-vent or tankless unit that does not use the chimney at all, and we tell you which one makes sense for your house. Sediment is the quieter killer: mineral settles on the tank floor, the burner fires through it rather than through water, and the steel above it cooks — which is why an annual flush and a look at the sacrificial anode rod is often the difference between a tank that dies at 8 years and one that reaches 12. Rural Burlington is a separate case. Homes north of Dundas Street around Kilbride and Lowville draw from private wells rather than Halton's supply, so hardness varies house to house and sulphur odour is common; a softener ahead of any tankless unit earns its keep there, and a powered anode in place of the magnesium one usually settles the rotten-egg smell that flushing alone will not.
On a service call we start with the cheap fixes: a failed thermocouple is $150–$300, a gas control valve that lights the pilot but never fires the burner is $400–$600, and a burnt lower element on an electric tank is $200–$400. A leaking tank is the exception, because rusted steel cannot be patched — that is a same-day replacement. A straight tank-for-tank swap runs $1,200–$2,500 installed, and a conversion to a Navien, Rinnai or Bosch tankless is $3,500–$6,500 depending on venting and whether the gas line needs upsizing. If you are paying a rental company $25–$45 a month for the tank in your basement, ask about a rental buyout while we are there; over 15 years that rental adds up to $4,500–$8,000 for a tank that costs a fraction of that to own. Our water heater replacement cost answer covers the full math, the Burlington service area page covers everything else we do in the city, and you can book a Burlington visit and we will price it standing in the basement.

Water Heater in Burlington — FAQs
How quickly can you replace a leaking water heater in Burlington?
Usually the same day. Shut the cold-water isolation valve above the tank, turn the gas control knob to off (or kill the breaker on an electric tank), and call — the truck leaves from North Service Road, so Aldershot, downtown or Alton Village is a short run. A standard swap takes two to four hours once we arrive. A tank dripping from the seam or the bottom cannot be repaired and the leak only gets worse, so do not wait overnight.
What does water heater repair cost in Burlington?
Most repairs land between $150 and $800. A thermocouple is $150–$300 and a gas control valve is $400–$600 on a gas tank; an electric heating element is $200–$400. The diagnostic visit is $90–$150 and is credited against the work if you proceed. On a tank under eight years old a repair is nearly always the right call; on one past 10 with rust weeping at the fittings or at the T&P relief valve, we will say so and price a replacement instead.
My furnace was replaced and the water heater is now alone on the chimney — is that a problem?
Often, yes. Look at the draft hood on top of the tank: white mineral staining, rust streaks, or a warm draft coming out of it instead of going up means the flue is not drawing. A chimney sized for a furnace and a tank is too large for the tank alone, so the exhaust cools, condenses and can spill. We check draft on older Burlington homes as a matter of course, and the options are a correctly sized liner, a power-vent tank, or a tankless unit that vents out the wall.
What does a tankless conversion involve in a Burlington house?
Three things decide it: gas supply, venting and water. The most common set-up — a 199,000 BTU Rinnai or Navien replacing an existing tank — lands at $4,200–$5,000 installed, plus $400–$1,200 if the gas line has to be upsized from the meter, which is common in 1950s–70s houses piped for a small tank and a furnace. The unit vents out the side wall in plastic pipe, so the chimney question goes away. Halton's moderately hard water means an annual descale flush at $150–$300; our guide to hard water and tankless units in Hamilton and Halton covers the maintenance side.
Can you replace a rented tank from Enercare or Reliance?
Yes. You ask the rental company for a buyout figure or a return, we install a tank you own, and the old one goes back to them. The rent-or-buy answer lays out the numbers: renting runs $25–$45 a month with annual increases, while buying is $1,200–$2,500 installed. Either way, get the rental company's figure in writing before we arrive so the decision is made once, not twice.
