Why Replace Your AO Smith Tankless Water Heater?

Tankless water heaters, including those from AO Smith, are designed to last longer than traditional storage tank systems. However, no system lasts forever. Here are some reasons why replacing your AO Smith tankless water heater may be the best choice:

1. Outdated Technology

If your current water heater is over 10-15 years old, it may lack the advanced features and energy-saving technologies available in newer models. Upgrading to a modern AO Smith tankless water heater means you’ll enjoy features like enhanced energy efficiency, improved flow rates, and smart controls for better performance.

2. High Energy Bills

Older water heaters become less efficient over time, consuming more energy to produce the same amount of hot water. Replacing your aging unit with a high-efficiency AO Smith model can significantly reduce your energy bills and lower your carbon footprint.

3. Frequent Repairs

Are you constantly dealing with costly repairs and breakdowns? When repair costs begin to pile up, it’s often more cost-effective to replace the unit entirely rather than continue investing in temporary fixes.

4. Inconsistent Water Temperatures

A well-functioning tankless water heater should provide consistent hot water on demand. If you’re experiencing fluctuating water temperatures, even after repairs, it’s likely time to consider a replacement.

5. Insufficient Hot Water Supply

If your current system can’t keep up with your household’s hot water demands, upgrading to a higher-capacity AO Smith model can ensure you never run out of hot water again.

6. Leaks or Corrosion

Visible leaks or signs of corrosion indicate significant internal damage. In most cases, these issues cannot be repaired and require a full system replacement.

7. Warranty Expiration

If your system’s warranty has expired, repairs may no longer be covered, making replacement a more cost-effective long-term solution.

8. Increased Property Value

Upgrading to a new tankless water heater is not only a smart choice for comfort and efficiency but also adds value to your home by offering modern amenities that future buyers appreciate.

Benefits of a New AO Smith Tankless Water Heater

Investing in a new AO Smith tankless water heater offers numerous benefits, including:

1. Energy Efficiency

AO Smith tankless water heaters are designed with advanced condensing technology, allowing them to achieve energy efficiency ratings of up to 98%. This means you’ll save money on energy bills while reducing environmental impact.

2. Endless Hot Water Supply

With a tankless water heater, you’ll never run out of hot water again. AO Smith systems heat water on demand, ensuring a continuous supply for all your household or business needs.

3. Space-Saving Design

Unlike traditional water heaters with bulky storage tanks, AO Smith tankless models are compact and wall-mounted, freeing up valuable space in your home or business.

4. Long Lifespan

Tankless water heaters typically last longer than traditional systems. With proper maintenance, your new AO Smith water heater can provide reliable hot water for 20 years or more.

5. Smart Features

Modern AO Smith water heaters come equipped with smart technology, allowing you to monitor and control your system remotely via a smartphone app. This makes it easy to adjust settings, track energy usage, and receive system alerts.

6. Environmentally Friendly

By using less energy and producing lower emissions, AO Smith tankless water heaters are an eco-friendly choice that helps reduce your carbon footprint.

7. Enhanced Warranty Coverage

AO Smith offers some of the best warranties in the industry, giving you peace of mind and protecting your investment for years to come.

Expert insights: AO Smith tankless water heaters in Metro Vancouver

Below is a CANRO technician's perspective on tankless water heaters as they apply in Metro Vancouver: what to look for, what to avoid, and what to expect. AO Smith is American (Wisconsin, 1874), best known for its ProLine XE high-efficiency gas tank and Voltex hybrid heat-pump water heater. The brand's strengths are extensive product range from basic 40-gallon tanks to commercial 100-gallon units, hybrid heat-pump tank leadership.

Vancouver's moderately hard tap water (around 60-100 ppm hardness in most of Metro Vancouver) affects tankless water heaters, combi boilers, and hot-water tanks — annual descaling is essential. CANRO has worked with AO Smith systems across Metro Vancouver since 1999, from older retrofits in Brentwood and Thompson to new builds in Metrotown and Yaletown. AO Smith is generally a strong fit for a wide range of homes from basic replacements to hybrid heat-pump tank upgrades qualifying for rebates.

Technical considerations for tankless water heaters in Metro Vancouver

Sizing. Tankless sizing focuses on peak GPM (gallons per minute) at design temperature rise. Vancouver's 7-9°C incoming water needs about 32°C rise for typical use — most family installs need a 199,000 BTU unit.

Lifespan. Annual descaling is essential in Vancouver's moderately hard water — without it, scale build-up on the heat exchanger cuts capacity by 30% and shortens lifespan to under 10 years.

Warning signs. Tankless issues include flow-rate drops (scale), ignition lockouts (gas pressure or flame-rod fouling), condensate-trap clogs, and recirculation pump faults on units with built-in pumps.

Common AO Smith tankless water heater issues CANRO diagnoses

Over 25+ years of AO Smith service calls across Metro Vancouver, the recurring issues we see are: pilot assembly failures on power-vent models, gas-valve electronics on 2015-2017 builds, anode-rod corrosion.

Parts availability. AO Smith parts are well stocked across BC and most repairs complete within 24-48 hours.

What CANRO checks during a tankless water heater service

  • Full descale of heat exchanger
  • Flame-rod inspection and clean
  • Combustion analysis
  • Flow-sensor test
  • Condensate trap clean
  • Air-intake screen clean
  • Gas pressure verification (inlet + manifold)
  • Internal filter clean
  • Error log download and review
  • Recirculation pump check if installed

AO Smith Tankless water heater FAQs

What's recirculation, and do I need it?

Recirculation pumps return cooled hot water from the far fixture back to the tankless, eliminating the cold-water wait. Many modern tankless units (Navien NPE-A, Noritz EZ) have built-in recirculation. Worth the upgrade for homes where the kitchen or master bath is far from the mechanical room.

How long does a tankless water heater last?

A condensing tankless gas water heater installed by a qualified contractor in Metro Vancouver lasts 18-22 years with annual descaling. Without annual descaling, lifespan drops to 10-12 years.

How much hot water can a tankless deliver?

A 199,000 BTU tankless in Metro Vancouver delivers about 5-7 gallons per minute at a 32°C temperature rise (Vancouver incoming water is ~7-9°C). That handles two simultaneous showers comfortably, or a shower plus a dishwasher.

How often does a tankless need descaling?

Annually in Metro Vancouver's moderately hard water. Without descaling, scale build-up on the heat exchanger cuts capacity by 30% within 3-4 years and shortens lifespan to under 10 years. CANRO descales tankless units as part of every annual service.

Does tankless save money vs a hot-water tank?

Tankless gas water heaters cut operating cost 25-40% vs a tank because they eliminate standby heat loss. Upfront cost is higher ($3,500-$6,000 installed vs $1,800-$3,200 for a tank), but most homes recover the difference in 6-9 years on gas savings.

Can a tankless run two showers at once in a Vancouver (AO Smith) winter?

Yes, with proper sizing. A 199,000 BTU condensing tankless will run two showers (at typical 1.8 gpm each) simultaneously through a Vancouver winter. For larger demand (3+ showers + dishwasher), consider linked tankless units or a combi boiler with built-in DHW recirculation.

Good to know

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.
What HVAC services does CANRO offer in Metro Vancouver?
CANRO installs, services and repairs boilers, furnaces, heat pumps, hot water tanks, tankless water heaters, gas fireplaces and air conditioning across Metro Vancouver. We work on residential homes, townhouses and condos throughout the Lower Mainland.
