Endless hot water — when it's working

A tankless water heater is a brilliant machine: hot water on demand, forever, from a unit the size of a suitcase. Until the morning it flashes an error code and everyone showers cold. We repair, maintain and install tankless units across Toronto, Ajax, Whitby and Uxbridge — all makes, with licensed gas technicians doing the gas side.

Repairs & maintenance

  • Error code diagnosis — tell us the code when you call; we often know the likely fix before we arrive
  • Descaling and flushing — hard GTA water is the #1 killer of tankless units; an annual descale is the difference between a 10-year unit and a 20-year one
  • Ignition, sensor and flow problems — the usual suspects behind cold-water sandwiches and units that cut out mid-shower
  • Venting and gas supply corrections — undersized gas lines starve tankless units; we fix the cause, not just the symptom

Thinking of going tankless?

Done right, it's a genuine upgrade: endless hot water, floor space back, lower standby losses. Done wrong — undersized unit, starved gas line, bad venting — it's a subscription to lukewarm disappointment. We size to your actual household and quote installation upfront, including any gas line work needed to feed it properly.

The honest comparison

Tankless isn't for everyone, and we'll say so. If your household is small, your gas service is limited, or the install economics don't work for your home, a quality conventional tank may serve you better for less. You'll get the real numbers for both and our honest read — then it's your call.

Tankless Water Heaters questions

My tankless unit shows an error code — can it be fixed?

Usually, yes. Most codes trace to scale buildup, a sensor, or gas supply issues — all repairable. Tell us the code when you call and we'll often know the likely fix before we arrive.

How often does a tankless water heater need descaling?

In our area's water, roughly once a year — more often with hard well water. Regular descaling is the difference between a 10-year unit and a 20-year unit.

Is tankless worth the switch from a tank?

If you run out of hot water, value floor space, or your tank is due anyway — often yes. But it's not right for every home, and we'll tell you straight if a conventional tank serves you better.
