What does the Turbulator dip tube actually do?

It's a dip tube designed to create a swirling water flow inside the tank as cold water enters, which is intended to keep sediment stirred up and flushed out rather than settling and hardening at the bottom. Sediment buildup is one of the more common reasons a tank water heater loses efficiency or capacity over time.

What size ProLine AV do I need?

The line spans 30 to 75 gallons. The 40-gallon model shown here has a 67-gallon first-hour rating, suited to smaller households; larger sizes are available for bigger homes or higher simultaneous hot water demand. We'll size it to your household's actual usage.

Is John Wood a reliable brand for Ontario homes?

Yes — John Wood is a long-established Canadian water heater manufacturer and one of the brands we install and service regularly. It's a common choice where a dependable, standard-vent gas tank fits the home better than a tankless or hybrid system.

What warranty comes with the ProLine AV?

John Wood backs the standard ProLine with a 6-year tank and parts warranty, extending to 8 years on the ProLine Master line.

Does this water heater qualify for a rebate?

No. Standard gas tank water heaters like the ProLine AV aren't part of Ontario's current electrification rebate programs, which target heat pump water heaters. Ask us about a hybrid option like the GE GeoSpring if a rebate matters to your decision.
