Tankless Water Heater Service in Greater Vancouver
Tankless water heaters provide on-demand hot water without a storage tank, offering energy efficiency and unlimited hot water for your household. Unlike traditional tank water heaters that store and continually heat 40 to 60 gallons of water, tankless units heat water only when you turn on the tap. They last longer (15 to 20 years vs 8 to 12 for tank units) and take up less space but require professional installation to ensure proper gas line sizing, venting, and water flow rates. Our licensed technicians install, service, and repair all major tankless brands including Navien, Rinnai, Rheem, Noritz, Bosch, and Takagi.
Tankless Water Heater Installation
Professional tankless water heater installation includes a site evaluation to determine the correct unit size based on your household peak hot water demand (measured in gallons per minute), incoming water temperature, and desired output temperature. Installation involves proper gas line sizing (tankless units often require larger gas supply lines), sealed combustion or direct vent venting, condensate drain installation for condensing models, water line connections, and startup testing. A licensed gas fitter must perform the installation per BC Gas Code requirements.
Tankless Water Heater Maintenance and Descaling
Tankless water heaters require annual descaling (flushing with a vinegar or descaling solution) to remove mineral deposits that accumulate on the internal heat exchanger. Scale buildup reduces efficiency, restricts water flow, and can eventually damage the heat exchanger. Our descaling service includes connecting a pump and cleaning solution to the service valves, circulating the solution through the unit for 45 to 60 minutes, flushing with clean water, cleaning the inlet water filter, and verifying proper operation afterward.
Tankless Water Heater Repair
Common tankless water heater repairs include error code diagnosis, ignition failure repair, gas valve service, flow sensor testing, heat exchanger descaling, venting system repair, electrical connection service, and water filter cleaning. Many tankless issues can be resolved with professional descaling and component cleaning. Our technicians have brand-specific diagnostic training for Navien, Rinnai, Rheem, Noritz, Bosch, and Takagi units.
Tankless vs Tank: Which Is Right for You?
Tankless water heaters save space, use less energy (no standby heat loss), and last longer than tank models. They provide unlimited hot water — no more running out during back-to-back showers. However, they cost more upfront, may require gas line upgrades, and have a limited flow rate that may be insufficient for simultaneous high-demand use (multiple showers + dishwasher + washing machine). A tank water heater costs less initially, is simpler to install, and can supply multiple fixtures at once. We can help you evaluate your household usage patterns and recommend the best option.

Safety Reminder
If you smell gas, suspect carbon monoxide or believe there is an immediate danger, leave the property and contact emergency services or the appropriate gas emergency authority. Do not remain inside — exit the building immediately and call for help from outside.
