Frequently Asked Questions

How do I determine the right size water heater for my family? To find the right size, consider your household’s hot water usage during peak times. A general rule is to allow 10-15 gallons of hot water for each person in your home.

What is the difference between tank and tankless water heaters? Tank water heaters store hot water and are typically used in larger households. Tankless models heat water on demand, which can save energy but may not supply enough hot water for simultaneous use in larger homes.

How often should I flush my water heater? Flushing your water heater annually helps remove sediment build-up, improving efficiency and extending the unit’s lifespan. Consider doing it every six months if you have hard water.

What should I do if I run out of hot water? Running out of hot water can happen if demand exceeds the capacity. You can adjust the thermostat, ensure the heating elements are functioning, and check for leaks that may be depleting hot water supply.

Do I need professional installation for these heaters? While some smaller models can be installed by homeowners, larger units or those requiring specific connections may need professional installation to ensure safety and compliance with local codes.
