"Excellent!! We were so impressed by Cory and amazed he and his team could perform work the same day. Husband and I relocated to Wisconsin from Alaska in June 2018. Hot water heater in house we bought brand new 9/2017. It broke and warranty didn’t transfer to new owners. Cory commented install in old unit not done by professionals. When work completed on new unit, it was like comparing a duct taped wreck to a sleek sports-car ! Excellent Plus job!! Cannot say enough thanks for kindness to us, Husband and I of 48 years feel Blessed Cory was our Professional. ?"

"My God! Dan came out this morning, I explained what was done, he went to work on it right away! My furnace stopped working December 25th, 2024, no heat till today! Keep in mind, the last technician I hired in January 2025, charged me 240 dollars for 20 minutes analysis just to tell me I need new furnace and AC central, my AC works beautifully. Then I used 4 space heaters to keep my house warm! Man my electric bill was over 400 dollars the first month and climbing higher each coming months till Spring arrived! I hired B & D Plumbing and Heater Co. to come out and finish the job. It was a gentleman name Dan, he did an extremely awesome job, telling me the details, explaining everything I needed to knowledge. And now the furnace works about as good as it gets beautifully. The impressive part, he took his sweet time. And the most impressive part was when he presented my total bill! I was about to have a major heart attack when I saw the bill! It wasn’t through the roof bill! Cheap cheap"

"Tony was great! Our hot water heater went out yesterday (4/20/15) and we did not realize it was out until 10 pm that night. The next morning (5:30 am) I submitted a request for service and Tony was able to come out by 7:15 am. Within 5 minutes Tony had the hot water heater running again. Along with the service Tony provided advice on how to prevent our issues again. Thanks Tony!"

"Matthews plumbing did a fantastic job repairing our water heater. Matt quickly returned our request for a service call. He went above and beyond by gathering any possible parts before coming to diagnosis the issue to ensure it was fixed on the same call. I would highly recommend Matthews plumbing to anyone who is having any issues."

Water Heaters FAQs, 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.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

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.

If your water heater is about to celebrate the big 2-0, you may want to consider sending it off to greener pastures. While the water heater may seem to be working well, any conventional, tanked water heater over 10 years of age is at risk of failure. If your water heater is 20 years or older, your best move is to replace your aging heater before it completely breaks down.

Yes, this would be an appropriate choice. In order to comply with the National Electric Code’s rules, you'll need to install a circuit breaker that's 125% larger than the intended load. In this case, you'll multiply 30 amps by 1.25 to find the necessary breaker size. Plugging that equation in for your 30-amp water heater will leave you with a 37.6-amp breaker. If your current water heater keeps tripping the breaker, it might be time to talk to a plumber or electrician about upgrading your water heater's setup.
