Why is this article on the cost of water heaters essential in 2025?

An increase in installation requests in Greater Montreal

By 2024-2025, the number of requests for water heater replacement has risen sharply, mainly due to the aging of the Quebec housing stock and new energy efficiency standards. This pressure led to an increase in installation price and delays with certain non-certified suppliers.

Understanding the factors that influence pricing

The total cost of a project can vary depending on several factors: the tank capacity (40, 60, or 80 gallons), the location of the water heater, any required electrical or plumbing modifications, and the choice of model (standard or tankless). That’s why it’s crucial to understand what influences the final quote.

When should a water heater be replaced in Quebec?

A worn-out or end-of-life water heaters can cause more than just a lack of hot water. It can lead to higher electricity bills, costly water leaks or even a back-up in the basement. Here's how signs to watch out for to find out if it's time to change your water heater in Greater Montreal.

Average life of a water heater

The majority of residential water heaters in Quebec have a average service life of 10 to 12 years. After this period, the risk of failure increases considerably, especially if the unit has not been maintained regularly or if the water in your area is hard.

Signs that replacement is necessary

  • Pressure or temperature drop hot water
  • Abnormal noises (rattling, hissing) coming from the reservoir
  • Visible leak at the base of the water heater
  • An appliance that is over 10 years old, even without visible symptoms.
  • Accumulation of rust or sediment in water
  •  

Replace before failure: a smart investment

Waiting for a complete breakdown can end up costing much more—especially if it leads to a flood or water damage. By planning a preventive replacement, you benefit from lower rates, peace of mind, and often better energy efficiency thanks to a newer model.

The average lifespan of a residential water heater in Quebec is between 8 and 12 years, depending on the model, water quality, and maintenance. Tank-style models, such as standard 40- or 60-gallon electric water heaters, are the most common. Brands like Giant, Rheem, and AO Smith offer warranties ranging from 6 to 12 years, which is a good indicator of their durability.

    • Leaky tank or leaks around the base A clear sign of corrosion or cracking. A leak can quickly cause major damage.

Installing a water heater in Quebec: key steps and advice

How long does it take to install a water heater?

In general, a certified plumber puts 2 and 4 hours to remove the old water heater, install the new one, make the connections, bleed the air from the system and test the system. All this can be done in a single visitoften in the morning or before the end of the day.

Typical steps for compliant installation

  1. Typical installation of an electric water heater in a Greater Montreal home by a certified plumber.Power or gas cut-off
  2. Complete emptying of the old tank
  3. Disconnecting water pipes and power supply
  4. Removing and safely disposing of old water heaters
  5. Installing the new water heater (level, orientation, anchoring)
  6. Connecting pipes and electrical system
  7. Air purge + leak test + start-up

Do I need a permit to replace a water heater?

In most cases in Quebec, no municipal permit is required for the simple replacement of a residential water heater, as long as the new unit has the same or lower capacity as the one being replaced. However, a permit may be required in the following cases:

  • from energy source conversion (e.g. electric to natural gas)
  • from major change of location or electrical circuit modification
  • installation in a flood risk zone (non-conforming basement)

 

🔧 Tip:

Allow a minimum clearance of 18 to 24 inches around the tank to facilitate future inspections and ventilation.

Cost of a water heater repair: intervention or partial replacement

Common repairable faults (thermostat, anode, valve)

Before considering a full replacement, some common issues can be resolved at a lower cost — such as a faulty thermostat, a worn-out anode, or a leaking pressure relief valve. These components can often be replaced without draining or changing the entire unit.

When repair is no longer profitable

If your water heater is over 8 to 10 years old or shows multiple issues at once, repairs may become inefficient or costly. For example, a rusted tank, multiple leaks, or persistently rusty water are all signs that a full replacement is often more cost-effective in the long run.

Average price for a quick home repair

Here are the average costs observed in Québec in 2025 for the most common water heater repairs :

Repair type Average price (CAD) Response time
Thermostat replacement 150 $ to 220 $ 1 to 2 hours

Tip: To avoid unexpected costs, always request a detailed quote that includes all fees.

Time required for a residential replacement

The standard replacement of a residential water heater takes between 2 to 4 hours, depending on site accessibility, electrical compliance, and the type of unit installed. For a typical tank model, the job is often completed within the same half-day.
