"I had a 40 gallon water heater burst and reached out to multiple plumbing companies. John was the first to contact me and understood the urgency of the situation. He was extremely professional, explained the "who, what, why" of everything that could, should, and would be done and provided all possible options for replacement with 4 different quotes. I hired him and he singlehandedly replaced and upgraded my water heater with zero issues. Keep in mind this all took place in a 24 hour window. I WILL be using J&K again for ALL of my plumbing needs. CANNOT RECOMMEND ENOUGH."

"Highly Recommend! I recently received a call from my father who lives in Burrillville RI with a severe plumbing leak. Living in NY, I panicked until I spoke with Bill over the phone (after calling two other companies and left messages. Bill answered). He asked great questions, and was able to instruct us over the phone where to shut the water off to the house until he could arrive. He shuffled his schedule to get to my father's house that day! Bill and his assistant found the issue, repaired it while on site, and the price he charged was well under what I anticipated! Phenomenal job, highly recommend!!"

"Bill was extremely responsive and a true professional. I could tell he had a wealth of knowledge. I had a short window of time to replace an indirect water heater. He was on it. Set the appt. to measure and the date to complete the job was exactly what I needed to keep guest plans for the upcoming weekend. I will be sure to keep his # handy!!! Great work, great job, and a nice guy. Hit the jackpot with this one!"

Water Heaters questions, answered by experts

On average, a tankless water heater should last between 10 and 15 years. Its lifespan will be affected by how much it's used, the effect of weather where your home is on the unit—colder is harsher and will shorten lifespan—and if the heater is maintained appropriately and regularly. There are many signs your water heater needs to be replaced, so pay attention to anything that changes with your heater or hot water.

Tankless water heaters heat water as it passes through the unit instead of storing heated water in the tank. Their ability to produce hot water on an as-needed basis makes them more efficient. However, they are generally more expensive than traditional units. Is a tankless water heater worth it? Most homeowners will save money with a tankless unit in the long run by using less energy.

Tankless water heaters are more expensive than those with a storage tank, but they come with some impressive benefits that most homeowners find worth the higher investment. Most importantly, they provide unlimited hot water, so you’ll never run out like you would with a storage tank. Tankless heaters are also more efficient, so comparing gallon-for-gallon, you’ll spend less on hot water with a tankless heater. Tankless water heaters are also smaller, require less maintenance, and tend to last longer than storage tank water heaters.

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.

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.
