Is your house a good fit?
Tankless heaters are rated by flow at a stated temperature lift. In winter, Toronto's incoming water is cold, so the rise is large and the flow drops. A unit that runs two showers in July may struggle with two showers and a dishwasher in February.
- Gas meter and supply pipe large enough for a high-input burner
- Wall space near an exterior wall for venting
- Willingness to descale the unit on schedule
- Household that values endless hot water over the lowest upfront cost
The install, step by step
- We size the unit from your fixtures and peak use.
- A licensed gas fitter checks the gas line and upsizes it if needed.
- The unit mounts on the wall and vents through the side with PVC or approved pipe.
- Cold in, hot out, with isolation valves for service.
- Condensate drain run to a floor drain or pump on condensing models.
- Startup, flow test at several taps and a walk-through of the controls.

From the counter
Hard water and descaling
Toronto water carries enough mineral that tankless heat exchangers scale up over time. The isolation valves let us pump a descaling solution through the unit. We tell you how often based on your use, typically once a year to start.
North York houses
Bungalows with a basement mechanical room usually suit tankless well: short runs and an easy side wall for venting. Semis and townhouses with the mechanical room in the middle of the house can need long vent runs. Condos generally do not allow it. We look before recommending anything.
Questions
Does a tankless heater work in a power outage?
No. It needs electricity for the controls and fan, just like a power-vent tank.
Do I wait longer for hot water?
A little, plus the time the water takes to travel the pipe. A recirculation setup can shorten the wait.

- We ask questionsAge of the building, pipe type if you know it, where the shut-off is.
- We open it upTrap off, clean-out open or wall cut: find the actual fault before quoting the fix.
- We test itOpen each tap on that run, watch the joints dry and show you what came out.
