How to hire a water heater installation & repair pro in Canada
- Use licensed plumbers and gas fitters (gas licensing is provincial — e.g. TSSA in Ontario); permits typically required
- Decide owned vs rented — tank rental is uniquely common in Ontario; check buyout terms before signing rental contracts
- Get unit, labour, permit, and disposal itemised
- Confirm venting compliance for gas units (many older chimneys need liners or power venting)
- Ask about heat pump water heater rebates from provincial/utility programs
- Register the warranty and record the anode-rod schedule for hard-water areas
Frequently asked questions
Is a leaking water heater dangerous?
A leaking tank can fail suddenly and flood, and any leak near electrics is hazardous. Shut off the unit's power (or gas) and its cold-water feed valve, then call a professional. A dripping pressure-relief valve specifically signals over-pressure or over-temperature — don't cap it.
Do water heaters need maintenance?
Yes: annual or biennial sediment flush, anode rod check every 2-3 years in hard-water areas, and TPR (pressure relief) valve testing. Tankless units need periodic descaling. Maintenance is the difference between an 8-year and a 15-year unit.
What size water heater does my home need?
Rule of thumb for storage: 30-40L per person per day of heated storage for typical use — a family of four lands around 150-200L (40-50 gal). For tankless, size by simultaneous outlets and the temperature rise your groundwater requires; your installer should calculate, not guess.
Why is my hot water running out faster than before?
Usually sediment buildup eating tank capacity, a failed lower heating element, or a broken dip tube mixing cold into the draw. All are diagnosable in one visit; sediment flushing and element swaps are routine repairs on a healthy tank.
How long does water heater installation take?
Like-for-like tank swaps take 2-4 hours. Fuel-type changes, relocations, tankless conversions, or units needing new circuits/venting run half a day to a full day plus possible permit inspections.
Tank or tankless — which is better?
Tankless gives endless hot water and saves space and standby losses, but costs more installed and may need electrical or gas-supply upgrades. Storage tanks are cheaper to buy and fix and handle simultaneous use predictably. Household size, fuel type, and usage pattern decide it.
Should I rent or buy my water heater in Canada?
Buying almost always wins over the unit's life — Ontario rentals commonly total 2-3x the purchase price over a decade, with exit fees. Rentals make sense only if you value zero repair risk short-term. Never sign a door-to-door rental switch without reading buyout terms.
