Tankless water heater installation
An on-demand unit lights its burner the moment a hot tap is opened and keeps going as long as you need. It frees floor space, but it needs a bigger gas supply, proper venting and service valves for regular descaling.
- Gas demand: Much higher than a tank while firing
- Venting: Usually PVC or polypropylene through the wall
- Maintenance: Periodic descaling flush
- Space saved: Unit hangs on the wall
- Licensed, insured trade work (details confirmed when you call)
- Diagnosis before anything is cut
- Emergency calls taken
- Etobicoke and the west end

Is your house ready
The heater draws a lot of gas while it runs. If the existing gas line was sized for a furnace and a small tank, it may need upsizing from the meter. We check the meter rating and pipe run before recommending a model.
- Venting must reach outside within the manufacturer’s limits, and condensing models must have somewhere to send their acidic condensate, which usually goes through a neutralizer.
Installation details that matter
We fit isolation valves with service ports so the heat exchanger can be descaled without cutting pipe. Lake Ontario water carries moderate hardness, so scale builds up over time, and a neglected exchanger loses efficiency.
- The unit is mounted on a solid backing with room around it for service, and a dedicated outlet where required.
Living with it
Hot water takes a few seconds longer to reach the tap because the heater must fire first. A tiny draw, such as a dribble at the vanity, may fail to fire it. Most people adjust quickly.
- Descaling at a regular interval keeps the unit efficient.
- We can show you how or do it for you.
Signs to watch for
- Tank needs replacing in a cramped utility room
- Back-to-back showers run cold
- Planning a basement suite
- Want to remove a rental tank
- Gas line already upgraded
