"I purchased an electric tankless and pre-filter/softener directly from the manufacturer and started hunting for a plumber to install it. Now most all plumbers recommended against a tankless hot water heater, and Maplewood wasn't really any different in this regard. BUT, they listened to us, didn't treat us like idiots, and obliged us in our foolishness and they were really awesome. They did the job quickly and without a mess. Also, WE LOVE OUR NEW TANKLESS HOT WATER HEATER! I looked at our electric bill after 2 months (March-April) of using our Stiebel-Eltron E-tankless whole-house water heater unit, and the kW usage actually DECREASED from one year ago for those same two months. That’s right, there was no increase in our electric bill. As expected, our gas usage decreased. My wife was very worried because she often ended up talking to the plumber issuing the dire warnings and predictions about our silly misguided endeavor to get a tankless unit. Now, she couldn’t be happier. Tandem back-to-back showers all day long, if we wanted. Never ending hot water! Thank you Maplewood Plumbing for helping us!"

"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet.  I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."

Water Heaters FAQs, answered by experts

You should replace your gas water heater when it’s reached the end of its lifespan, which is a maximum of 12 years in most cases. If your unit is over a decade old and showing signs of inefficiency, leaks, or frequent malfunctions, it may be time to replace your water heater. Research how to best maintain your gas water heater to help extend its lifespan.

Flushing biannually, checking the anode rod, and temperature settings maximize equipment lifespan while reducing surprise costs.

Installing a water heater without a permit can result in high fines—as much as hundreds of dollars per day, in some areas. It can also void your homeowners' insurance and cause problems when selling your home because it violates local building codes and safety regulations.

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.

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.
