"I purchased a heat pump electric water heater to take advantage of a generous rebate from Efficiency Maine. When looking for someone to install it I was referred to Jophil by a real estate company that I know. I called and was given a time that Kyle would arrive to give an estimate and perform the installation (if the estimate was accepted). I did accept the estimate and Kyle got right to work. He did a nice job and made sure that everything was in good working order before he left. I was very pleased with my first experience with this company and would not hesitate to call on them again in the future."

"We got TWO (you see in pics one has green seat cover, the other purple) Kohler water saver 1.28gpf plug free toilets! I have special needs with my back and we got exactly what we wanted round bowl and standard height. He upgrades from glacier bay to awesome #1 Kohler us because of an initial miscommunication that we easily worked out. Yay! No more plugging AND water savings so they will pay for themselves within a year. Thank you Chuck. We will call your for our next plumbing job!"

"This is not for a water heater, but it was the only option I could choose. Recently I had an issue with my kitchen sink not draining. I tried to snake it myself and found out my pipes were brittle and put the snake right through them. Reached out to Toye and he was here the next day. Replaced the piping under my sink, then took the time to find and clear what turned out to be a massive clog that the snake I was trying to use never would have cleared. HUGE thanks to Ramon!"

"Although it was difficult to reach them on the phone, once they had an opening they got us right in. The technicians were very knowledgeable. The previous owner had not properly installed the pump, so the water was not being pumped out of the house. They chose the best location for the water to be pumped out and did a great job with clean up. I was pleased with their knowledge, demeanor and workmanship. I will use them again."

Water Heaters FAQs, answered by experts

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

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.

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.

The lifespan of a water heater depends on its type, usage, and maintenance schedule. Traditional tank-style water heaters typically last between 8 and 12 years, though the range can be as wide as 6 to 15 years. Within this category, gas models often last 8-12 years, while electric models may last 10-15 years. In contrast, tankless water heaters have a significantly longer lifespan, often lasting up to 20 years or more. Factors like heavy usage, hard water, and sediment buildup can shorten a unit's life. To extend its lifespan, it is crucial to perform regular maintenance, such as flushing the tank annually and scheduling professional inspections. If your unit is over a decade old and shows signs of rust, leaks, strange noises, or inconsistent heating, it is likely time for a replacement.

A larger heater requires a larger breaker—unless there’s one already installed. The longer answer to this question is more nuanced. Do you place demands on the heater at the same time as running other heavy-duty appliances like ovens and washing machines? Do you live in an older home that may not have considered the higher electrical demands we have now? Breakers need to be sized at 125% of the load. To find that load, you should call a local electrical pro.
