"They did a good job as far as the quality of work, they cleaned up after themselves and they were punctual. They called after the services were performed and asked when they would receive their money, this was before I had even received a bill. Felt that they were rushing me through the inspection due to wanting payment for the job. They didn't split the lines for the two separate tenants, so hot water was going to both apartments from the water heater which was only hooked up to one apartment. When I called to have this fixed, they stated that I should have told them this prior to the work and they were going to charge me like a new customer to come out and get it repaired. However, when I contacted them originally, I stated that the only thing coming between the two apartments was cold water. Graded quality nonapplicable because quality of work was good, but was done incorrectly, and felt their attitude about the correction was way off base."

"My technician, Timothy N., was timely and thorough in replacing my water heater and sump pump. I live in an old house with a lot of outdated plumbing. He inspected and replaced some old valves and copper piping that was developing a leak. He took his time to make sure that everything was completed properly. He even made sure that the temperature setting was the same as it had been before. (I have young children who like to play with the faucets, and I didn't want the temperature too hot.) I really like the look of my new water heater and everything is working great."

"I highly recommend Benjamin Franklin Plumbing. They cam within a day of when I called, assessed and fixed one problem, installed a new water heater the same day, and returned the next day to install new pipes above the water heater. The plumbers were polite, professional, and explained clearly what they were doing. Pricing was very reasonable and I also have a yearly service contract. Office personnel were also friendly and knowledgeable. Will only use them from now on."

Water Heaters FAQs, answered by experts

Several things can void the warranty for your water heater. Many water heater manufacturers state that installing your own will void the warranty. However, even if you get away with performing the task yourself, incorrect installation, lack of a building permit, and improper repair work, regardless of licensing status, can all render your water heater unprotected by both the manufacturer's warranty and any installation warranties. 

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.

Most standard residential water heaters, which are typically around 40 gallons and use 240 volts and between 3,500 and 5,500 watts, require a 30-amp, two-pole circuit breaker. For smaller, point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts, a 30-amp breaker is also often adequate. However, some models may have different needs; units that use more watts than average may require a 40-amp breaker, while smaller units might only need a 20-amp breaker. Newer, tankless, or more energy-efficient models can also require a higher amperage. Having the correct breaker size is crucial for safe and efficient operation, so it's best to consult a licensed electrician to determine the specific needs of your water heater.

If your system is not vented properly, you could experience what’s called backdrafting. Backdrafting is when your ventilation system isn’t working as it should, and instead of releasing gases outside, they get trapped inside your home. 

Gas and propane water heaters create a few types of combustion gases, but the most dangerous is carbon monoxide. If there’s too much build-up of these gases inside your home, it can lead to carbon monoxide poisoning.

If you have a tank-type electric water heater, it runs regularly to keep the water at the desired temperature. If you live in a home where you don’t use much hot water, it could seem wasteful to run power to heat water that you’re using infrequently. You could save some power by using a smaller tank, insulating the tank, or lowering the temperature of the water heater.
