"I hesitated during this virus to have my water heater replaced, but John and his assistant came in with full masks, gloves, and booties, so I felt very safe. I have already recommended them to a neighbor. His price was lower than the one received by my neighbor by another service."

"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

Not all types of water heaters require a venting system. Electric tankless water heaters don’t use natural or propane gas, so no venting is required. Instead, they use electric burners to heat water quickly and efficiently. However, any system that does use gas or propane will require ventilation.

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.

If you're replacing a broken water heater, now is a great time to make sure you're selecting a unit that has the right capacity for your household. According to the U.S. Department of Energy, a small 50-gallon to 60-gallon tank is sufficient for households with one to three people. A medium-sized 80-gallon tank is considered ideal for three to four people. A larger tank may be needed if your household has four to six people.

Going from a tank to a tankless water heater is one of the most effective ways to lower your utility bills. The switch also frees up more space and ensures a consistent hot water supply, as the water is heated on an as-needed basis. It costs between $5,400 and $7,400 to install a new tankless water heater. Most installation companies will also help dispose of your old water tank.

Due to the high temperature, using stainless steel vent pipes for your tankless water heater’s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.
