Burnaby's tankless water heater installed base has grown significantly over the past decade, and the systems span two distinct profiles. In the established residential neighborhoods of Capitol Hill, Sperling-Duthie, and South Slope, homeowners added tankless units during kitchen or bathroom renovations, replacing aging hot water tanks with on-demand systems. These units are now 8 to 12 years into their service life and developing the component wear that comes with heavy residential use: flame rods fouling from years of ignition cycles, flow sensors drifting out of calibration, and heat exchangers accumulating the mineral scale that Metro Vancouver's moderately hard water deposits over time. The second profile is Burnaby's newer condo and townhome construction around Metrotown, Brentwood, and along the Lougheed corridor, where tankless units were installed as builder-standard equipment. These systems are younger but sometimes develop problems rooted in the original installation: undersized gas lines that restrict burner performance, venting configurations that were marginally compliant from day one, or inlet filter placement that causes nuisance low-flow errors.

Scale buildup inside the narrow passages of a tankless heat exchanger is the single most common cause of performance issues in Lower Mainland homes. Metro Vancouver's water carries moderate mineral content that deposits gradually with every litre that passes through the system. Over years of use, these deposits narrow the flow path, reduce heat transfer efficiency, and eventually trigger error codes that lock the unit out. Descaling flushes a specialized solution through the heat exchanger to dissolve accumulated mineral deposits and restore flow rates and temperature consistency. It is a standalone maintenance service, separate from standard diagnostics and repair. Not every tankless unit needs descaling on the same schedule; homes with higher hot water demand or harder water accumulate scale faster. We assess heat exchanger condition during every diagnostic and recommend descaling when the buildup justifies it, not as a blanket upsell.

Eaton's Heating has been repairing tankless water heaters across Burnaby for over two decades from our Coquitlam shop on the Burnaby border. We are a FortisBC Trade Ally, BBB A+ rated, and Technical Safety BC licensed under LGA0200006. Our 400+ five-star Google reviews and 4.9 average rating reflect precise fault identification on computerized appliances that most general plumbers and HVAC companies lack the brand-specific training to diagnose. We carry diagnostic tools for every major residential tankless brand and test gas pressure, water flow rates, ignition components, sensors, and control boards during every service call. All repairs use CSA certified parts backed by a six-month warranty.

For homeowners whose tankless unit is beyond cost-effective repair, we also install new tankless systems from Navien and Rinnai in both condensing and non-condensing configurations, with and without built-in recirculation for instant hot water at every fixture. For homeowners considering a switch back to a conventional hot water tank, we explain the trade-offs clearly: tanks cost less upfront but use more energy and eventually corrode out, while tankless units last longer and heat on demand but cost more to install and maintain. We service furnaces, boilers, and all other HVAC systems across Burnaby.
