FAQ

Q: Why is my gas water heater not producing enough hot water suddenly? A: Sudden reduction in hot water can indicate thermostat problems, gas supply issues, or heating element failure. Professional diagnosis can identify the specific cause and solution.

Q: How can I increase my hot water capacity without replacing my water heater? A: Options include installing a recirculation system, adding point-of-use heaters, improving insulation, or installing a second water heater. A professional assessment can recommend the best solution.

Q: What size water heater do I need for my Toronto home? A: Water heater sizing depends on household size, usage patterns, and peak demand. A professional can calculate your specific needs and recommend appropriate capacity.

Q: How often should I flush my gas water heater to maintain hot water production? A: Annual flushing is recommended for most homes, with more frequent flushing in areas with hard water. Regular flushing prevents sediment buildup that reduces hot water production.

Q: Can hard water affect my gas water heater's hot water production? A: Yes, hard water causes mineral buildup that insulates the tank from the burner, reducing heating efficiency. Water softening and regular maintenance can address this issue.

Q: What temperature should I set my gas water heater for optimal hot water production? A: 120°F is recommended for safety and efficiency, providing adequate hot water while preventing scalding and reducing energy consumption.
