"Bennett responded quickly and was able to replace my hot water heater same day. I had many questions and he answered all of them so I had a better understanding of how things worked. Very professional, knowledgeable, friendly, and efficient. Affordable on top of all that. I would highly recommend them to anyone looking to repair or replace a hot water heater."

"I dealt with Sears and Home Depot all morning trying to arrange for a same-day install of a new water heater.  Sears didn't have the models in stock that they quoted and the quote at Home Depot kept changing and I was very dissatisfied with the second person I dealt with who seemed to be very slow and lacking in knowledge. In frustration and desperation, I called Green Homes and the person I dealt with (Maggie) was wonderful.  She told me they could have someone out here by 3pm (I didn't call them until almost noon), she took basic information and gave me a firm quote that included everything (no extras or add ons).The truck arrived a little before 3.  They discussed with me what  they were going to do, told me they would be done in about 2 hours.  In two hours, they were done,  they installed a new water heater,installed a new shut off valve for the hot water, it was immaculate, the old one was gone, instructed me how to use it and that was that.  It was one of the best experiences I have ever had from beginning to end.  The price was exactly as they quoted.  The guarantee was for two years labor and ten years parts - better than any quoted. I will use them again and absolutely recommend them.  This is my first experience using a listing on Angie's List - that too was a good experience."

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.

Depending on the brand of water heater, you may need to install an expansion tank in order to meet the conditions for warranty coverage. It’s important for consumers to read the fine print of the warranty to see if an expansion tank is necessary. Even if an expansion tank isn’t required for the warranty, it’s usually mandated by building codes—although not for tankless water heaters.

Electric water heaters use a high amount of electricity, so they’re best for homeowners who subsidize their electric bill with solar or who live in an area with inexpensive electricity. For others, gas water heaters versus electric water heaters may be the more cost-effective solution, with the added bonus of heating water quickly and efficiently. No matter which you choose, you can lower your water temperature as low as possible to keep costs down.

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.

Most standard residential water heaters, which are typically around 40 gallons and use 240 volts and between 3,500 and 5,500 watts, require a 30-amp, two-pole circuit breaker. For smaller, point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts, a 30-amp breaker is also often adequate. However, some models may have different needs; units that use more watts than average may require a 40-amp breaker, while smaller units might only need a 20-amp breaker. Newer, tankless, or more energy-efficient models can also require a higher amperage. Having the correct breaker size is crucial for safe and efficient operation, so it's best to consult a licensed electrician to determine the specific needs of your water heater.
