"I highered Bruce and his team, we're very happy with the service. They installed a couple new baseboard heaters to our existing unit to add more heat to a few rooms that's were cooler than we liked. We're very happy and much warmer. Bruce and his team were responsive and open to everything they were doing. Fast and efficient highly recommended!"

"Called the original installers from 12 years ago but they weren’t very responsive. Ray Page responded with same day service and worked with my schedule. They sent text alerts with picture of Scott. Scott has been to my house before to fix Kitchen faucet and garbage disposal. Very professional and nice. This time, he did the big job, replaced the water heater and cleaned up as well. Very reliable service."

"My heat was not working after being off for a few months and we were worried that we were going to be cold for a while.. David and Kailey came right out and did an AMAZING JOB!! I legit had to turn my heat down after they left because it went from no heat, to working too perfect! My apartment is the warmest it’s been even from last winter and I’m anemic so this is wonderful. They walked us through everything they did and they were fast and EFFICIENT! I would hire them to do any work needed in my apartment for sure! Thank you for the awesome customer service, and the wonderful job well done! Seriously couldn’t thank them enough!"

"Our water heater started leaking on a Sunday. I waited til Monday morning to start calling plumbers. I wanted a hot water heater with heat pump that would be eligible for a $750 rebate thru Energize CT. Fred was not familiar with the program, but made a few calls to gather info, called me to discuss and then ordered the unit which was delivered later that day. Unit was installed next morning. Fred was great to deal with, communicated with me throughout the process & did a fantastic job. I even asked for a quote to install a sink in my basement. I highly recommend him to anyone in need of plumbing services."

"Outstanding professional service all around by N & J Plumbing from the moment I was contacted by Nick on a Saturday (when my water heater began leaking), who initially guided me on the phone as to the actions I needed to take to gradually stop the leak - until the replacement of my water heater on Monday by Nickâ s team."

Water Heaters FAQs, answered by experts

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.

Examples include gas stoves, ovens, and water heaters. Confirm with your provider for specific items.

You don’t have to replace expansion tanks at the same time as your hot water heater. You may be able to go six to 12 years or more before needing to replace your expansion tank. At $150 to $450, hot water heater expansion tanks are usually much more affordable than the cost of hot water tanks themselves, which average about $1,190.

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.

The average cost to install a new water heater is approximately $1,300, with a typical price range between $880 and $1,800. The final cost depends on several factors, including the type and size of the unit, its location and accessibility, and the amount of labor required. For example, installing a unit in a tight space like a crawl space can increase labor costs. The type of water heater significantly impacts the price: while a conventional gas heater might cost less than $1,000, tankless models can cost around $2,600 to install (and up to $3,500), and solar heaters can cost upwards of $3,700. Other factors that can affect the total price include the fuel type, vent system requirements, permits, and whether any additional plumbing work or repairs from previous water heater damage are needed.
