"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

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.

A tankless water heater with a flow rate of 10 GPM should replace a conventional 50-gallon water heater. To avoid a surprise cold shower or two and to keep your energy costs in check, it's important to replace a conventional tanked water heater with the equivalent tankless water heater. Your household size and the number of hot-water-using devices you use at once can help you determine the best-size tankless water heater.

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.

There are pros and cons to tankless water heaters. They are more efficient than traditional tank water heaters, and maintenance costs are lower. These units are also much more compact. On the other hand, they cost about twice as much to install as traditional tank water heaters and are more limited in terms of flow rate.

If you want instant hot water and to reduce water waste while improving convenience, a hot water recirculating system is worth it, especially if you find your hot water heater is not hot enough. These systems can save thousands of gallons of water each year so you don't have to wait for hot water at faucets and showers. The upfront investment can be high, especially for systems requiring additional plumbing, but the long-term savings on water bills and added comfort make them a worthwhile upgrade.
