Hot Water That Doesn't Run Out, Installed Right

Tankless makes particular sense for certain Kelowna homes. Large Upper Mission and Wilden houses with multiple bathrooms, soaker tubs, and simultaneous-demand hot water needs. Newer builds in The Ponds, McKinley Beach, and Black Mountain where clean utility rooms and adequate gas supply make installation straightforward. Downtown condos where floor space is at a premium. And rental properties across Rutland and Glenmore where the long-term math favors a tankless lasting twice as long as a tank.

We install tankless systems across every Kelowna neighborhood. From plug-and-play new-build installs with modern gas service to complex retrofits in older homes that need gas line upgrades and new venting runs before the tankless will run properly. Our quotes cover every piece of the job, including gas line sizing and condensate routing that other installers often forget until the unit is already onsite.

  • Tankless installs (natural gas & propane)
  • Whole-home sizing for peak demand
  • Gas line upgrades for tankless capacity
  • Sidewall & roof venting
  • Tank-to-tankless retrofits
  • Commissioning & warranty registration
What We Handle

Tankless Services for Kelowna Homeowners

  1. New Build Installs

    The Ponds, McKinley Beach, Black Mountain, and Wilden new homes: tankless installed right from day one, sized for the household and integrated with the home's gas plan.

  2. Tank-to-Tankless Retrofits

    Replacing an aging tank in an older Kelowna home usually requires a larger gas line and new venting. We scope and price the complete job up front with no change orders mid-install.

  3. Large-Home Sizing

    Upper Mission and lakefront homes with multiple bathrooms and soaker tubs need careful BTU math. Kelowna winter inlet temperatures affect the sizing — we calculate for reality.

  4. Outdoor Kitchen & Hot Tub Supply

    Lakefront properties around Gyro Beach and Mission, plus Upper Mission entertaining homes, often benefit from a dedicated tankless for outdoor showers, kitchens, or hot tubs.

  5. Suite & Carriage Tankless

    Separate tankless units for basement suites and laneway homes so the main home's hot water isn't shared or overdrawn — and utilities can be billed correctly.

  6. Commissioning & Registration

    Every install gets properly commissioned and registered with the manufacturer so the warranty is valid from day one — not voided because paperwork wasn't filed.

How It Works

A Tankless Install Done Right

  1. Household Demand Review

    How many fixtures run at once? Large tub? Pool or hot tub tie-in? We ask the questions that determine the right BTU rating for your actual Kelowna household.

  2. Gas Line & Venting Assessment

    Most tankless units need a 3/4" gas line, sometimes 1". We check your existing service and scope any upgrade needed before the quote: not on install day.

  3. Written Quote

    Unit, gas line upgrade if needed, venting, condensate drain, electrical, and commissioning, all of which are itemized. You know every number before we order equipment.

  4. Clean Installation

    Lines run cleanly, unit level, venting to spec, condensate drain tied in properly. A tankless install is a real install: we treat it that way.

  5. Commissioning & Walkthrough

    Flow-test every fixture, register the warranty, walk you through temperature settings and the annual maintenance requirement (non-negotiable in Kelowna water).

Why Stevenson

Why Kelowna Homeowners Pick Us for Tankless

We Size for Winter

Kelowna January inlet water is cold. We size at winter delta-T, not summer brochure numbers. The tankless keeps up when the whole family is home and showers stack up.

Gas Work In-House

Most retrofits need a gas line upgrade. Our licensed gas fitters handle it: no scheduling a second contractor, no finger-pointing on warranty calls.

Hard Water Planning

We pair tankless installs with softener recommendations when the test warrants it. Skipping this is why Kelowna tankless units fail at 8 years instead of 20.

Service Relationship

We flush, descale, and maintain what we install. Annual maintenance in Kelowna water is essential! We make the booking easy.

Common Questions

Tankless FAQ in Kelowna, BC

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

The unit is only part of the cost. Gas line upgrades, venting, and condensate routing often add $1,500–$4,000 to a tank-to-tankless retrofit. We quote the complete job so there are no surprise charges mid-install.

Often no, especially in Abbott Street, South Pandosy, and older Glenmore and Rutland homes. Most tankless units need a 3/4" line. We assess at quote time and price the upgrade if needed.

In Kelowna, yes. Hard water scale builds up inside the heat exchanger and kills efficiency and lifespan. Annual flushing is the single biggest factor between a tankless lasting 20 years and failing at 8.

Well-maintained tankless: 20+ years. Standard tanks: 8–12 in Kelowna water. Tankless costs more up front, but the lifespan math often favors it over full ownership.

Yes, if sized correctly. We calculate GPM at your required temperature rise, the math matters more than the box. For very high-demand homes, a multi-unit install sometimes makes more sense than one large unit.

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!
