Water Heater Replacement for Navien water heaters

Most replacement calls start with a leaking tank, a unit past 12 years, or a repair that no longer makes sense. A leaking tank body is the one fault that cannot be fixed: shut off the cold supply and the gas or power, and the job becomes a replacement. CANRO states on its own site that standard 40 or 50 gallon gas or electric tanks are typically replaced same-day or next-day, with availability confirmed by phone.

A replacement is also the moment to decide whether like-for-like is right. Staying with an atmospheric tank under a working flue is the lowest-cost path and keeps hot water during outages. Moving to a power-vent or condensing tank, a heat-pump unit or a tankless heater changes venting, gas or electrical supply, condensate and sometimes location, which is where quotes differ. The estimator itemizes those as adders so nothing is hidden, and the written estimate after a visit is free.

Working on a Navien unit? Have the model number from the rating plate and any code or flash pattern ready. Browse Navien series, models and fault codes to find yours; the details carry through when you request service.

Frequently asked questions

When should I replace rather than repair?

A leaking tank body, unavailable parts, repeated faults, or a tank past roughly 12 years usually favour replacement. A single clear fault on a younger unit favours repair.

Can I replace a 40 gallon tank with a bigger one?

Often, if the space, flue and gas supply allow. Size by first-hour delivery, not nominal volume; a 40 gallon tank with a good recovery rate may already deliver what you need.

Will a new water heater lower my gas bill?

A condensing or higher-UEF unit uses less energy than an old atmospheric tank, but the saving depends on your usage. WaterHeating.ca publishes no savings claims.

Do I need a permit to replace a water heater in BC?

Yes. A gas permit, and in municipalities such as Burnaby a plumbing permit too. CANRO obtains them.
