Tankless Water Heater · Etobicoke, OntarioTankless Water Heater Installation in Etobicoke
Tankless water heater installation in Etobicoke typically costs $4,200–$5,000 for a 199,000 BTU gas unit replacing an existing tank, inside a full range of $3,500–$6,500. Budget a further $400–$1,200 if the gas line has to be upsized, which is common in post-war bungalows piped for a small tank and a furnace. A TSSA-licensed gas technician does the gas, venting and water connections, and the quote is written before anything is ordered.
What a tank-to-tankless conversion involves in an Etobicoke house
Gas supply decides most Etobicoke conversions. A post-war bungalow was piped for a furnace and a tank drawing about 40,000 BTU an hour, often on a half-inch branch, and a tankless unit at full fire draws 199,000. We add up every gas appliance in the house, measure the pipe run from the meter and size the new line from that, which is where the $400–$1,200 upsizing figure comes from. If the total load is more than the meter can pass, Enbridge Gas changes the meter, and we tell you that at the quote.
Venting changes completely. The old tank drafts up the brick chimney; a condensing tankless unit pushes cool exhaust through plastic pipe out a side or rear wall, with clearances from windows, doors, the gas regulator and air intakes set by CSA B149.1 and the manufacturer. In a bungalow the water heater usually sits mid-basement beside the chimney, so the new unit either moves to an outside wall or gets a longer vent run, and both are drawn on the quote. The unit also needs a 120-volt receptacle and a drain for condensate, two things a standing-pilot tank never asked for.
Three situations change the advice. If the tank in your basement is a rental, sort out the buyout or return first; replacing a rental water heater with your own tankless walks through the steps. If the house heats with a boiler and radiators, as some Kingsway, Mimico and Long Branch homes do, a combi boiler can make heat and hot water from one wall-hung appliance. And in the Humber Bay Shores towers hot water generally comes from the building's central plant, so there is nothing in the suite to convert.
Etobicoke gets Toronto's Lake Ontario water, which is moderately hard, so scale builds on a tankless heat exchanger over time. We install isolation valves on every unit so the annual descale flush, $150–$300, is a short visit. Incoming water is coldest in late winter, which is when any tankless unit delivers its lowest flow, and that is the condition we size for; see what size tankless water heater you need.

Tankless Water Heater in Etobicoke — FAQs
How much does tankless water heater installation cost in Etobicoke?
Budget in three lines. The typical conversion, a mid-tier 199,000 BTU Rinnai or Navien replacing a tank, is $4,200–$5,000 installed. Gas-line upsizing, where the existing pipe is too small, adds $400–$1,200. The full range across unit sizes and vent routes is $3,500–$6,500. A straight tank swap, for comparison, is $1,200–$2,500, and we quote both if you are undecided.
Will my bungalow's gas line need upgrading for a tankless unit?
Often, but not always. It depends on pipe diameter, the length of the run from the meter, and what else is on the line: furnace, range, dryer, fireplace, barbecue. A short three-quarter-inch run near the meter may be fine; a long half-inch branch will not feed 199,000 BTU. We measure and calculate at the quote visit, so the answer is on paper before you commit to anything.
How long is the house without hot water during the install?
Plan for one working day. The old tank is drained and removed in the morning, the unit is hung, piped, vented and wired, and the gas line is pressure-tested before the first fire. A long gas run, a new vent route through a finished ceiling or a relocated unit can push the job into a second day, and the quote says so in advance.
Is tankless worth it for two people in a bungalow?
Not always. Tankless pays for larger households: endless hot water, $80–$200 a year in lower running costs, and a 15–20 year life against 8–12 for a tank. For two people who never run out of hot water, a $1,200–$2,500 tank is often the better buy. The exceptions are a basement apartment sharing the supply, a soaker tub, or floor space you want back.
Does a tankless water heater work during a power outage?
No. A gas tankless unit needs 120-volt power for its fan, ignition and controls, so it stops when Toronto Hydro's supply does and restarts when power returns. An old standing-pilot tank kept working through an outage, which surprises people after a conversion. If outages worry you, a small battery backup or a generator circuit sized for the unit solves it; raise it at the quote.
