Tankless Water Heater Installation in Kamloops

Tankless water heaters heat water on demand — there's no storage tank that constantly uses energy to keep water hot. This translates to roughly 25–34% energy savings for homes that use less than 155 litres of hot water daily, and 8–14% savings for heavier usage. Over the 20+ year lifespan of a Rinnai tankless unit, Kamloops homeowners can save $3,000–5,000 in energy costs compared to a traditional tank.

Proper sizing is critical in Kamloops. Our winters regularly see groundwater temperatures drop to 2–4°C, which means the tankless unit needs to raise incoming water temperature by 45–55°C to reach a comfortable 50°C output. The Rinnai RU199iN delivers up to 199,000 BTU, which can handle 3–4 fixtures running simultaneously even in Kamloops' coldest months. Our quiz accounts for your home's fixture count, household size, and groundwater temperature to recommend the right model.

Tankless installations are more involved than tank replacements, typically taking 4–6 hours. Your contractor will remove the old tank, mount the new Rinnai unit on the wall, run new stainless steel venting (concentric or twin-pipe depending on your home's layout), upgrade the gas line if needed (tankless units require a ¾" gas line), connect water lines, install condensate drainage (for condensing models), and complete all electrical connections. Every installation includes the City of Kamloops plumbing permit.

The $3,200+ starting price includes the Rinnai unit, all labour, venting materials, gas line work, permits, and local code items. While the upfront cost is higher than a tank ($1,450 for gas, $1,200 for electric), the math works out over time: a tankless unit lasts 20+ years vs. 8–12 for a tank, meaning you'll replace a tank 2–3 times in the same period. Factor in energy savings and the lifetime cost of ownership is often lower with tankless.

For homes where the hot water fixtures are far from the water heater, the Rinnai RXP series includes a built-in recirculation pump. This eliminates the wait for hot water at distant faucets — hot water arrives in seconds instead of minutes. It's especially popular in larger Kamloops homes with master bathrooms on the opposite end of the house from the mechanical room.
