Why is tankless so much more than a tank?

The unit itself is only part of it. A tankless heater burns much harder while it runs, so a first-time conversion usually needs a larger gas line and a new stainless venting run, and those two lines are often more than the price difference on the equipment. A tankless-to-tankless replacement later on is far cheaper, which is where the long-run saving shows up.

Is a heat pump water heater worth it?

It uses roughly a third of the electricity of a standard electric tank and attracts rebates in most provinces, so on electric heating it pays back reasonably fast. The catches are that it needs a reasonable volume of surrounding air to draw heat from, so a small sealed closet will not do, and it cools and dehumidifies the space it sits in, which is welcome in a basement and less so elsewhere.

Do I need a permit to swap a water heater?

For gas or electrical work, yes, and the estimate above adds a permit line whenever you select a gas or heat pump option. An electric tank swapped like for like is treated more leniently in some municipalities. Confirm with yours, because an uninspected gas appliance can affect an insurance claim.

How long should a water heater last?

A storage tank typically lasts 8 to 12 years, and a tankless unit 15 to 20 with descaling. If yours is over ten and you are already renovating nearby, replacing it while the space is open costs less than doing it as an emergency later, when you pay for urgency and have no time to compare quotes.

Why All of P.E.I. differs

All of P.E.I. prices about 8% below Ottawa, which is the baseline our regional model is anchored to.

Regional multiplier: 0.92×
Versus Ottawa: -8%
Province: Prince Edward Island
Sales tax on services: HST (15%)

Regional multipliers are anchored to Ottawa at 1.00 and scaled using Statistics Canada's Residential Renovation Price Index and Building Construction Price Index movements by census metropolitan area, then cross-checked against published contractor rate ranges. They are planning-level adjustments, not surveyed local quotes.
