When to replace your water heater?
An electric water heater lasts 10-15 years on average, a gas water heater 8-12 years. If your unit is over 10 years old and shows any of these symptoms, replacement is recommended:
- Insufficient hot water or lukewarm water despite correct thermostat setting
- Unusual noises (knocking, whistling)
- Visible leak or rust on the tank
- Abnormally high electricity bills
Choosing the right type of water heater
The electric water heater is the most common in Quebec. Simple to install and less expensive upfront, it's ideal if you don't have a natural gas connection.
The heat pump water heater is the most economical to operate — it uses 2-3x less electricity. The higher upfront cost is offset by available rebates.
The natural gas water heater is more economical if you're connected to the Energir network. Gas heats water faster and operating costs are generally lower than electricity.
