Upgrade to Endless Hot Water Smarter, Cleaner, More Efficient

Tired of running out of hot water halfway through a shower? Ready to stop heating 50 gallons of water 24 hours a day just in case someone needs it? A tankless water heater — also called an on-demand or continuous hot water system — heats water only when you need it, delivering a constant supply without the standby energy waste of a traditional tank.

Williamson Mechanical & Contracting installs and services tankless water heater systems throughout the Lower Mainland, including Surrey, Vancouver, Burnaby, Coquitlam, Langley, Richmond, and Abbotsford. We’re licensed gas fitters and plumbers in BC, and we install top-rated brands including Navien, Rinnai, and Noritz.

Is Your Home Right for a Tankless System?

Most homes in the Lower Mainland are excellent candidates for tankless installation. Natural gas tankless heaters are the most popular choice here because of BC’s existing gas infrastructure. We’ll evaluate your gas line size, venting options, and hot water demand before recommending a system. Some older homes in New Westminster, Burnaby, or Vancouver may need a gas line upgrade, which we handle as part of the installation.

Frequently Asked Questions

Find quick answers to the most common questions about our plumbing services, pricing, and availability.
How much does tankless water heater installation cost in BC?
Installed costs typically range from $2,500 to $5,000 depending on the unit selected, any gas line upgrades required, and venting complexity. We provide transparent, itemized quotes before work begins.
Will I really save money going tankless?
Yes, in most cases. Tankless heaters eliminate standby heat loss, which accounts for 15–30% of a traditional tank’s energy use. Most homeowners see meaningful savings on their FortisBC bill within the first year.
How long does tankless installation take?
A straightforward replacement takes 4–6 hours. If gas line upgrades or new venting runs are needed, it may take a full day. We’ll give you a clear timeline upfront.
Do tankless heaters need maintenance?
Yes. Annual flushing to remove mineral buildup is recommended, especially with hard water common in parts of the Lower Mainland. We offer maintenance service to keep your system running at peak efficiency.
What if I have an electric home — can I go tankless?
Electric tankless units are available, but they require significant electrical upgrades in most homes. Gas tankless systems are far more practical and cost-effective for most BC homes with existing gas service.
