Frequently Asked Questions

Why did my water heater suddenly stop working?

Water heaters can work well until there’s a serious problem. It’s possible to have an underlying issue with the system and not know until a repair or replacement is needed.

Why should I switch to a tankless water heater?

Tankless water heaters take up much less space than traditional tank-style water heaters. They also provide energy efficiency, as they only run when hot water is needed.

How long should my water heater last?

Typically, a water heater will last for 10 years or more. Regular maintenance and flushing of the system can also help lengthen the life span.
