How It Works

What Affects the Price

Frequently Asked Questions

How much does a tankless water heater cost to install?

Tankless installation starts at $4,500 + HST on our pricing list. The spread above that usually comes down to whether your gas line and venting need upgrading.

Is a tankless water heater worth it?

It gives you endless hot water, frees the floor space a tank occupies, and typically lasts longer than a tank. The trade-off is a higher upfront cost and the gas and venting work that comes with it.

Why does a tankless unit need a bigger gas line?

A tank heats water slowly and steadily at a modest BTU rate. A tankless unit heats on demand and fires at a much higher rate, so the existing line often cannot supply enough gas.

How long does a tankless water heater last?

Typically fifteen to twenty years with annual descaling, compared with eight to twelve for a tank.

Does a tankless heater need maintenance?

Yes. Annual descaling keeps mineral buildup from restricting the heat exchanger, which matters more in hard water areas. Tankless maintenance is $225 + HST on our pricing list.

Will I run out of hot water with a tankless unit?

Not by volume, but flow rate is finite. If the unit is undersized for the number of fixtures running at once, temperature drops. Correct sizing at the quote stage prevents this.
