"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."

"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

Electric water heaters use a high amount of electricity, so they’re best for homeowners who subsidize their electric bill with solar or who live in an area with inexpensive electricity. For others, gas water heaters versus electric water heaters may be the more cost-effective solution, with the added bonus of heating water quickly and efficiently. No matter which you choose, you can lower your water temperature as low as possible to keep costs down.

When installing a new furnace, it's a good time to consider other projects that can enhance your home's energy efficiency. A great first step is to get a home energy audit, which will identify areas for improvement. Common recommendations include sealing or replacing windows and adding insulation to the attic. These upgrades can help you save money on monthly utility costs. You might also consider installing a smart thermostat to make heating your home more convenient and efficient.

A larger heater requires a larger breaker—unless there’s one already installed. The longer answer to this question is more nuanced. Do you place demands on the heater at the same time as running other heavy-duty appliances like ovens and washing machines? Do you live in an older home that may not have considered the higher electrical demands we have now? Breakers need to be sized at 125% of the load. To find that load, you should call a local electrical pro.

A water heater is one of the heaviest hitters in your home, and it needs as much power as possible to help it run efficiently and effectively.

Your water heater should be on its own dedicated circuit breaker, with no other power sources running to it. This is required to meet the National Electric Code–and to ensure it runs as efficiently as possible.

If your gas water heater is over 20 years old, it should be replaced. Gas water heaters can last up to 12 years and while they can exceed this expectancy if well-maintained, a heater that's 20 years old would require replacement. The heater is unlikely to run as efficiently as a new model and could be more expensive to do so.
