Tankless Water Heater Installation in Barrie, Ontario
A tankless water heater heats water only when you need it — no storage tank to empty, and no running out mid-shower. We install, service, and repair tankless units for homes and businesses across Barrie and Simcoe County.
Tankless, Sized and Installed Properly
A tankless unit is not a like-for-like swap with a storage tank. The right unit depends on how much hot water your household uses at once — showers, laundry, and the dishwasher running together — plus your gas supply, venting route, and where condensate will drain. We work through all of that at your free estimate, so the unit we install keeps up on the coldest morning of the year, not just on paper.
We also service and repair existing tankless units. Hard water scale is the most common reason a tankless heater struggles or throws an error code, and regular descaling keeps heat exchangers efficient and extends the life of the unit.
- Sized to your household's actual hot water demand

A tankless water heater mounts on the wall and is roughly the size of a suitcase — it only heats water when a tap opens, instead of keeping a full tank hot around the clock.
