Why Capitol Hill homeowners look at tankless

A lot of the interest in tankless on the Hill comes from space — older basements here often have a mechanical room that's doing double duty with the furnace, laundry, and storage, and freeing up the footprint a storage tank used to occupy matters in a smaller renovated space. Continuous hot water is the other draw, especially in households running back-to-back showers or a laundry cycle at the same time as a shower without the tank running out partway through.

It's not automatically the right fit for every home, though. A tankless unit needs a properly sized gas line and dedicated venting, and on some older Capitol Hill properties the existing gas service was sized for a smaller appliance load, which the technician has to check before pricing the job.

Installation cost breakdown

The wide span reflects how different two tankless jobs can be — swapping a tankless unit for another tankless unit on the same venting is a much smaller job than converting from a storage tank, which often means new venting, a new condensate line for a condensing model, and sometimes an upsized gas line.

What pushes the price toward the higher end

• Converting from a storage tank — this usually means all-new venting rather than reusing what's there, plus a condensate drain if the unit is a condensing model.
• Gas line sizing — a tankless unit draws more gas at once than a storage tank, so an undersized existing line may need to be upsized.
• Venting run length — a mechanical room far from an exterior wall needs a longer vent run, which adds material and labour.
• Access on a sloped lot — bringing the unit and venting materials into a basement mechanical room via a steep or narrow route adds time.
• Electrical — most gas tankless units need a standard outlet nearby; if one isn't already there, that's additional work.
• Parts tier and warranty length selected for the unit.

Tankless vs. a new storage tank

Tankless costs more up front than a comparable storage tank installation, largely because of the venting and gas line work involved when converting from a tank. Where it tends to make sense is a household that's frequently running out of hot water on a storage tank, or a renovation where reclaiming the tank's floor space is worth the added installation cost. Where a storage tank still makes more sense is a straightforward like-for-like swap with no space constraint and no history of running short on hot water — there's no need to take on the bigger installation job just to have the word 'tankless' on the appliance.

CANRO's technicians will walk through both options honestly during the assessment rather than steering every household toward the higher-cost system.

Permits and what the assessment covers

A tankless installation needs a City of Burnaby gas permit, and the work must be carried out by a Technical Safety BC licensed gas fitter — CANRO holds gas licence LGA0043870. During the assessment, the technician measures the existing gas line and meter capacity, checks a viable venting route to the exterior, confirms clearances around the unit, and looks at whether a condensate drain is needed for the model you're considering. That assessment is what turns the ballpark range into an actual quote for your home.
