We add up the fixtures you might run at once and size the unit in litres per minute, accounting for winter inlet water temperature.
Tankless units fire at a much higher BTU rate than a tank, so the gas line and venting usually need upgrading.
Old tank removed, new unit wall-mounted, which frees the floor space the tank occupied.
Gas line sized and run, stainless venting installed, condensate drain fitted on condensing models.
We verify gas pressure under load, check temperature rise at the tap, and set the target temperature.
This is the most common cost driver. A tankless unit often needs a larger line run back to the meter.
Tankless units require stainless or PVC venting rather than the old tank's flue, usually routed to a new exterior penetration.
Higher flow rates cost more. A home with two bathrooms in simultaneous use needs a larger unit.
Condensing units are more efficient and need a condensate drain.
Hard water areas benefit from a scale filter or isolation valves for descaling, which adds a little to the install.
Tankless installation starts at $4,500 + HST on our pricing list. The spread above that usually comes down to whether your gas line and venting need upgrading.
It gives you endless hot water, frees the floor space a tank occupies, and typically lasts longer than a tank. The trade-off is a higher upfront cost and the gas and venting work that comes with it.
A tank heats water slowly and steadily at a modest BTU rate. A tankless unit heats on demand and fires at a much higher rate, so the existing line often cannot supply enough gas.
Typically fifteen to twenty years with annual descaling, compared with eight to twelve for a tank.
Yes. Annual descaling keeps mineral buildup from restricting the heat exchanger, which matters more in hard water areas. Tankless maintenance is $225 + HST on our pricing list.
Not by volume, but flow rate is finite. If the unit is undersized for the number of fixtures running at once, temperature drops. Correct sizing at the quote stage prevents this.
