Tankless Water Heater · Burlington, OntarioTankless Water Heater Installation in Burlington
Three measurements set the price of tankless water heater installation in Burlington: the gas line size, the vent route and the water hardness. The common job, a 199,000 BTU gas unit replacing a tank, lands at $4,200–$5,000 installed, inside a full range of $3,500–$6,500. Upsizing the gas line adds $400–$1,200 in houses piped for a small tank, and the quote is free and written.
Converting a Burlington home from a tank to tankless: gas line, venting and water
The gas line is where Burlington houses differ most. The 1950s–60s bungalows in Roseland, Shoreacres and Aldershot were piped with half-inch line for a furnace and a small tank, and a tankless at full fire draws several times what that tank did, so the run from the meter is usually upsized. The 1970s–80s two-storeys in Headon Forest, Brant Hills and Tyandaga vary house to house, and we size the pipe from its length and the total load, using the tables in CSA B149.1, before we promise anything. We also add up the connected load on the meter: when the furnace, range, fireplace, barbecue line and the new heater together exceed what the meter can deliver, Enbridge Gas upsizes it, and that request goes in before install day.
Venting is the second measurement. A condensing tankless breathes through two plastic pipes out the rim joist, which retires the tank's chimney connection in an older bungalow and means the power-vent pipe from a 1990s or 2000s tank in Millcroft or the Orchard is checked against the new unit's requirements instead of being reused on trust. The termination has to keep its code clearances from windows, doors, the gas meter and the lot line, which on a narrow Alton Village side yard sometimes decides which wall the unit hangs on. The unit also needs a 120-volt outlet and a drain for its condensate.
Water is the third. Halton's municipal supply is hard enough to scale a heat exchanger, so every installation gets isolation valves and a plan for an annual descale at $150–$300. Above the Escarpment, Lowville and Kilbride homes on private wells need more: a sediment filter and usually a softener ahead of the heater, a check that the well pump holds steady pressure at shower flow, and a propane-configured unit where there is no gas main. A whole-house electric tankless is rarely practical on a rural panel because of the amperage it draws, so for those houses we also price a tank or a heat pump water heater.
On install day the old tank is drained and removed, the gas line and vents are run by a TSSA-licensed fitter, and the unit is commissioned with a combustion check and a flow test at your fixtures. If the tank being replaced is a rental, get the buyout or return terms from the rental company first; rental buyouts in Burlington explains how. The tankless water heater service page covers sizing and brands, the tankless cost guide itemizes the quote, and booking a free assessment gets you the written number.

Tankless Water Heater in Burlington — FAQs
What does tankless water heater installation cost in Burlington?
The common job, a 199,000 BTU Navien or Rinnai replacing a gas tank, is $4,200–$5,000 installed. The full range is $3,500–$6,500 depending on the unit and the vent route, and upsizing the gas line adds $400–$1,200 where the existing pipe is too small. A tank swap, for comparison, is $1,200–$2,500. Every figure is confirmed in writing after we see the mechanical room.
Will my existing gas line work for a tankless?
Often not in Burlington's older houses. A half-inch line that fed a tank in a 1950s–70s home cannot carry a tankless at full fire along with the furnace, and the unit will starve and fault on a cold morning. We size the pipe by length and total load and price the upgrade up front. Whether a tankless needs a bigger gas line explains the calculation.
Is a tankless worth it for my household?
It pays in three cases: a household of four or more that runs out of hot water, a tank past ten years that needs replacing anyway, or a mechanical room where floor space matters. You get endless hot water, $80–$200 a year in lower running cost and a 15–20 year lifespan against 8–12 for a tank. For one or two people with a healthy tank, keeping it is the cheaper choice.
Do I need a permit or inspection for a tankless in Burlington?
The gas piping and venting fall under CSA B149.1 and must be done by a TSSA-licensed gas technician, which is the main legal requirement. Whether a building permit is also needed depends on what else the job changes, so we confirm with the City of Burlington Building Department before work starts and tell you at the quote. A new electrical circuit, if one is required, is ESA work.
What maintenance does a tankless need on Burlington water?
An annual descale flush at $150–$300 on untreated water, plus a cleaned inlet screen and a combustion check. Scale is what shortens a heat exchanger's life, and a softener can stretch the interval to every second year. When something does go wrong, tankless repair in Burlington covers error codes, ignition faults and the parts that wear.
