"I appreciated being able to speak with someone in the office to explain my situation (leaking water heater), and having someone come to my home so quickly to go over my options for dealing with the problem. Dylan, Aaron and the entire crew were so professional and knowledgeable about the on-demand hot water system we chose to install. They were a pleasure to work with, and I would highly recommend them to friends in need of similar services."

Water Heaters FAQs, answered by experts

Most hot water heater manufacturers recommend replacing the anode rod about once every three to five years. Anode rods sacrifice themselves by collecting iron, limestone, and other minerals that would otherwise corrode your hot water heater tank. This abuse wears them out long before your water heater does. Check the rod when you remove it and replace it if more than 50% of the metal has been consumed. Check the rod more frequently if you have hard water or use a water softener. 

A tankless water heater can last up to 20 years, which is nearly double the lifespan of a conventional tank heater. However, their longevity is highly dependent on several factors. With proper installation and regular maintenance, such as descaling to prevent mineral buildup from hard water, you can expect a lifespan of 15 to 20 years. Without proper care, a tankless unit may begin to fail in as little as 12 years. Other factors that affect its lifespan include household usage and the quality of the local water supply. While they have a higher upfront cost, their energy savings, smaller size, and longer life make them a worthwhile investment for many homeowners.

The time it takes to install or replace a water heater depends on the type of heater and the complexity of the job. A professional can typically replace a standard tank-style water heater in one to three hours. However, if the work area is tight, such as a small closet or crawl space, the job could take four to five hours. Replacing an existing tankless unit takes about two to three hours, while upgrading from a tank-style to a tankless water heater is more complex and can take four to six hours. The project will take longer if you are switching fuel sources, such as installing a gas heater which can add about an hour to the timeline, or if the unit needs to be relocated.

Examples include gas stoves, ovens, and water heaters. Confirm with your provider for specific items.

Storage, tankless, heat pumps, and solar water heaters each suit specific space constraints, usage needs, and efficiency preferences.
