Why Bosch Greentherm tankless works in Metro Vancouver
Bosch’s Greentherm line is the tankless side of Bosch Thermotechnology (the same group behind Buderus boilers), and it’s a strong fit for Metro Vancouver homes converting from a storage tank to continuous, on-demand hot water. The Greentherm 9000 and 8000 series are the models we install and service most — condensing units with high recovery rates for homes that want to eliminate standby heat loss and lower their gas bills.

Bosch Greentherm Tankless FAQs from Metro Vancouver homeowners
Is Bosch Greentherm a good tankless water heater?+
Yes — the Greentherm line is a well-regarded condensing tankless platform from Bosch Thermotechnology, the same group behind Buderus boilers. CANRO installs and services Greentherm alongside Rinnai, Navien, and Takagi, and will recommend the right fit for your home’s demand and venting.
Greentherm 8000 or 9000 — which do I need?+
The 9000 series is built for higher, simultaneous-fixture demand (larger households, multiple bathrooms running at once); the 8000 series comfortably covers typical single-family demand at a lower installed cost. CANRO calculates your home’s peak demand before recommending either.
Does a Bosch Greentherm tankless qualify for a FortisBC rebate?+
Qualifying high-efficiency condensing models are generally eligible for FortisBC natural-gas water-heater rebates. CANRO confirms your specific model’s eligibility and files the paperwork.
Why is my Bosch tankless throwing an error code?+
The most common causes are scale buildup restricting flow, a blocked or frozen condensate line, or an ignition/flame-sensor fault — see our Bosch tankless error code guide for code-specific detail, or call for same-day diagnosis.
How long does a Bosch Greentherm tankless last?+
With annual descaling and condensate-system maintenance, a properly sized Greentherm typically lasts 15–20 years — longer than a comparable storage tank.
Can CANRO service a Bosch tankless another company installed?+
Yes — we install, repair, descale, and replace parts on Bosch Greentherm tankless units across Metro Vancouver regardless of who installed them.

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.
