Tankless Water Heater FAQs
Q: How does a tankless water heater differ from a traditional hot water tank?
A: Traditional water heaters continuously heat and store water in a tank, whereas tankless systems heat water instantly only when a hot water faucet is turned on, using gas burners or electric elements.
Q: Do I need to upgrade my gas line to install a gas tankless water heater?
A: Gas tankless units require a higher BTU rating than standard tank heaters to heat water instantly. Our licensed gas fitters evaluate your existing gas line and perform any necessary upgrades.
Q: How often does a tankless water heater require flushing?
A: Tankless systems should be descaled and flushed once every 12 months to remove hard water mineral scale from the heat exchanger and maintain manufacturer warranties.
Q: Can a tankless water heater supply enough hot water for a large family?
A: Yes, provided the unit is sized correctly based on gallons per minute (GPM) demand. For very large homes with heavy concurrent water usage, we can install dual units operating in parallel.
Q: Do tankless water heaters qualify for provincial energy rebates in BC?
A: Yes, qualifying high-efficiency ENERGY STAR® gas tankless models qualify for FortisBC and CleanBC energy efficiency rebates.
Q: How long do tankless water heaters last compared to tank heaters?
A: Tankless water heaters have an average operational lifespan of 18 to 20 years, nearly double the 8 to 12-year life expectancy of conventional storage tanks.
