Hot Water That Doesn't Run Out

The pitch for tankless is simple: endless hot water, a fraction of the floor space, and lower standby energy losses than a 60-gallon tank running 24/7. The reality is more specific: a tankless only delivers on those promises if it's sized correctly for peak demand, has adequate gas supply, vents properly, and gets maintained for Vernon's hard water. Done right, it's transformational. Done wrong, it's a very expensive appliance that throws error codes and short-showers the family.

We install tankless systems across Vernon and the North Okanagan. Whether you're in a newer Turtle Mountain and Middleton Mountain builds with clean utility rooms and ample gas supply, to retrofit installs in older East Hill homes that need gas line upgrades before the tankless will run properly. Our quotes cover every piece of the job, including the ones other installers forget about until they're already onsite with the unit unboxed.

  • Tankless installs (natural gas & propane)
  • Whole-home sizing & BTU calculations
  • Gas line upgrades for tankless capacity
  • Proper venting (sidewall & roof)
  • Tank-to-tankless retrofits
  • Commissioning & manufacturer warranty registration
What We Handle

Tankless Services for Vernon Homeowners

  1. New Tankless Installs

    Sized to your household's peak demand, with gas supply and venting planned properly from day one. Not a plug-and-play swap — a real install.

  2. Tank-to-Tankless Retrofits

    Replacing an aging tank with a tankless usually requires a larger gas line and new venting. We scope and price the full job up front, not in change orders.

  3. Whole-Home Sizing

    Tankless units are rated at a GPM at a given temperature rise. Vernon's cold inlet temps change the math. We size for realistic winter performance, not summer brochure numbers.

  4. Outdoor Kitchen & Hot Tub Supply

    Dedicated tankless units for pool houses, outdoor showers, and hot tub top-ups around Okanagan Landing and Predator Ridge properties.

  5. Suite & Secondary Tankless

    Separate tankless units for basement suites or carriage houses so the main home's hot water isn't shared, overdrawn, or billed to the wrong unit.

  6. Commissioning & Registration

    We register the unit with the manufacturer so your warranty is actually valid from day one — not invalid because no one filed the paperwork.

How It Works

A Tankless Install Done Right

  1. Household Demand Review

    How many fixtures run at once? What's the morning peak? Hot tub or large soaker tub? We ask the questions that determine the right BTU rating for your actual use.

  2. Gas Line & Venting Assessment

    Most tankless units need a 3/4" gas line minimum, sometimes 1". We check what you have and scope any upgrade needed before quoting — so no surprises on install day.

  3. Written Quote

    Unit, gas line upgrade if needed, venting, condensate drain, electrical, and commissioning — itemized. You know every number before we start.

  4. Clean Installation

    We run lines cleanly, mount the unit level, handle venting to manufacturer and code spec, and tie in the condensate drain properly. Tidy install, no improvisation.

  5. Commissioning & Walkthrough

    We flow-test at every fixture, register the warranty with the manufacturer, and walk you through temperature settings and maintenance requirements.

Why Stevenson

Why Vernon Homeowners Pick Us for Tankless

We Size for Winter

Vernon's January inlet water is cold. We size at winter delta-T, not summer, so your tankless actually keeps up when the family's all home and showers are stacked.

Gas Work In-House

Most tankless retrofits need a gas line upgrade. Our licensed gas fitters handle it — no second contractor, no scheduling dance, no finger-pointing.

Hard Water Planning

We pair tankless installs with a water softener recommendation when the test warrants it. Skipping this is the single biggest reason Vernon tankless units fail early.

Service After Install

We flush, descale, and service what we install. Tankless needs annual care in Vernon's water — we make it easy to book and stay on the schedule.

Common Questions

Hot Water On Demand FAQ — Vernon, BC

Yes — as long as it's sized for your household's peak demand. Undersized, and simultaneous showers will drop flow or temperature. Proper sizing is the entire game — the unit itself is secondary.

Wide range — the unit cost is only part of it. Gas line upgrades, venting, and condensate routing often add $1,500–$4,000 to a tank-to-tankless retrofit. We quote the full job so you don't get mid-install surprise charges.

Often no — especially in older Vernon homes. Most tankless units need a 3/4" line, sometimes 1". We assess during the quote and price the upgrade if needed, as part of the written scope.

Yes — annually, minimum, in Vernon. Hard water scale builds up in the heat exchanger and kills efficiency and lifespan. An annual flush is non-negotiable if you want the unit to last 20 years instead of 8.

Well-maintained tankless units run 20+ years. Standard tanks average 8–12 in Vernon's water. Tankless costs more up front, but the lifespan math often favors it over a full ownership cycle.

Yes, if sized correctly. We'll calculate the GPM at your required temperature rise and confirm whether one unit fits your needs or whether a multi-unit install makes more sense for the household.

Shadd and his team are absolutely wonderful and did a great job. I needed a basement sink plumbed and new washer dryer hookups and they were able to get it done in short order, kept everything tidy and were super easy to deal with. They knew my budget and worked with me to stay within it and gave me everything I needed. They are very professional, skilled and their prices are more than reasonable. I would highly recommend them to everyone!

HIGHLY RECOMMENDED BY US! 4 weeks ago, our hot water and air conditioning quit working on the same day! I called and spoke with the AMAZING Denise, she had Alex out at our shop within the day and he had everything diagnosed and parts ordered, not long after the first appointment, he had our hot water back in working order and then our A/C was repaired after that! Anytime we have had any issues, they have been very prompt to show up on the same day and Alex fixed it all! Such amazing and friendly services! You all have a forever client with Integra Tire and our team moving forward! Thank You!

Plumbing problems are never fun, but we appreciated how Stevenson Mechanical handled the replacement of our sump pump --from booking the appointment to the on-time arrival of our plumber and his friendly, competent service (which included persevering through some unexpected issues). Thank you for your expertise and excellent service!

This company is great! We needed to have our air conditioning unit disconnected and moved temporarily as we were getting our backyard patio redone. They were able to accommodate our last minute request, they completed the work quickly and got our unit reconnected just in time to beat the heat ! I would highly recommend them!
