"Excellent job installing a new water heater and carrying away the old one. The job was done well and timely. They were also available to advise me on other little plumbing issues that I had. Overall, I was pleased with what they did."

"Everything went pretty good. One weird situation happened when they had opened up the wall behind the shower surround. It had some old insulation that had gotten wet. We knew going in that there would be some water damage, since the old surround had cracked. They didn't plan on replacing the insulation, even though it was soaking wet! When I asked about it, I was told to go buy new insulation and they would install it the next day. At the same time,  there was some slight mold on the wall studs. I asked about the mold. I was told to get a bucket of bleach water and scrub down the mold areas! All that being said, Joe did go out of his way to help me with a problem in a different part of my house. Everyone was polite and easy to talk to and answered all my questions. They went above and beyond when venting the new exhaust fan. There was a nest of wasps in the gable vent of my house. Cutting the hole for the vent stiffed them up quite a bit, but Tony and Joe braved the wasps and got the job done!

"The yearly service works out to be $50 a month. We've had two water heaters replaced through them because of a fault in them. They're usually very responsive. I like that I can request the service online. The only thing is, I wish that there was a better avenue for emergency services. If something doesn't work right away usually it takes a couple of days to get someone out and sometimes you can't wait two days without water."

Water Heaters FAQs, answered by experts

No state requires you to vent an electric water heater. Other installation requirements for water heaters will vary, though, depending on the state and local jurisdiction in which you live. Some places require permits, while others don’t. Some may force you to place the appliance a certain distance from any walls or other appliances, while others don't. When you find a local professional to install a water heater, this expert will ensure you follow all the local regulations.

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.

When installing a new furnace, it's a good time to consider other projects that can enhance your home's energy efficiency. A great first step is to get a home energy audit, which will identify areas for improvement. Common recommendations include sealing or replacing windows and adding insulation to the attic. These upgrades can help you save money on monthly utility costs. You might also consider installing a smart thermostat to make heating your home more convenient and efficient.

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.

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.
