What’s included
| Check | Why it matters |
|---|---|
| Descaling flush | Metro Vancouver/Fraser Valley water is soft, but scale still builds slowly in the heat exchanger over years |
| Inlet filter cleaning | A clogged filter reduces flow and can trigger error codes |
| Venting & combustion check | Confirms safe, efficient operation |
| Error-code history review | Recurring codes often point to an issue worth addressing before it causes a shutdown |
| Gas pressure check | Confirms the unit is getting the supply it needs for full output |

Frequently asked questions
How long does a hot water tank last?
A standard gas or electric storage tank lasts 8–12 years. A high-quality tank with annual anode rod inspection can reach 15 years. Tankless water heaters typically last 18–22 years when descaled annually in Metro Vancouver's moderately hard water.
Should I switch to a tankless water heater?
Tankless makes sense if you have high demand (large family, multiple bathrooms running at once), want to free up floor space, or value endless hot water. Upfront cost is higher ($3,500–$6,000 installed vs $1,800–$3,200 for a tank) but operating cost is 25–40% lower for gas tankless.
My hot water tank is leaking — is it an emergency?
If the leak is from the tank body itself (not a valve or fitting), the tank is at end of life and needs replacement, usually within 24–48 hours before it floods. Shut off the water supply and gas/electric to the tank and call us.
What brands of water heaters do you install?
We install and service Bradford White, Rheem, AO Smith, John Wood, Giant, GSW for storage tanks; and Navien, Rinnai, Noritz, Bosch and Rheem for tankless units.
Can I install a water heater myself?
In BC, gas water heater installations must be performed by a TSBC-licensed gas fitter and are subject to permit and inspection. Electric tanks require a licensed electrician for the connection. CANRO handles permits as part of every installation.
