"recently had our water heater replaced and had a great experience from start to finish. The team was professional, knowledgeable, and completed the installation quickly and efficiently. They explained everything clearly, cleaned up after the job, and made the whole process stress-free. The new water heater works perfectly, and we couldn’t be happier with the service. I would definitely recommend them to anyone needing water heater replacement or plumbing work!"

"Robert came out right away and gave me a quote to buy and install a new tankless hot water heater. His price was FAR better than the other quotes that I received for the same heater. He agreed to come out and install it right away and did a great job. No mess, no hassle.. He was willing to answer all my questions and make sure everything was satisfactory before he left. I will use him for ALL future plumbing projects that come up in the future!"

Water Heaters FAQs, answered by experts

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Unusual noises, lack of hot water supply, efficiency loss, and visible leaks are signs of necessary replacement beyond mere repair.

No, you’ll need to drain the tank before changing a water heater element, as the water heater element sticks through the side of the tank and uses a gasket to prevent water from pouring out. However, you don’t always need to drain it completely. If you’re only replacing the upper heating element, you can drain the tank until the water line is below the element. If you’re replacing the lower element, you’ll need to drain the whole thing.

Tankless water heaters heat water as it passes through the unit instead of storing heated water in the tank. Their ability to produce hot water on an as-needed basis makes them more efficient. However, they are generally more expensive than traditional units. Is a tankless water heater worth it? Most homeowners will save money with a tankless unit in the long run by using less energy.

You can use multiple tankless water heaters, but that doesn’t mean you should. Adding multiple tankless heaters adds considerable cost to your home in both parts and installation costs. Also, you’re adding many more points of failure in the system, making plumbing issues harder to diagnose. More heaters mean more maintenance, and insurers may want a word regarding the increased risk of water damage. A single, larger unit makes more sense in most situations.
