"Justin and Cam, the technicians, did a great job. We have an old farmhouse with a very strange configuration of partial crawlspace and partial full basement, and water was leaking through the fieldstone foundation wall from the crawlspace. They quickly diagnosed that the problem was coming from 1 or 2 zones of the hot water radiator heating system, and they were able to shut off those zones to stop the leak, while allowing the house to still use water for sinks, toilets, and showers. We'll have to do more work later to replace pipes to the radiator but, because they are hard to access, we need to plan ahead for some construction work. I'm fully satisfied that these guys were able to find the problem and give us even a temporary solution that allows us to have our working plumbing again without the basement getting wet. Would definitely work with them again."

"This is a great company. I have a 2 family with only 1 water heater, and it needed to be replaced. Chris went over all the options with me and explained everything very well. He helped me figure out the best option for my property with no pressure and no upselling. Matt and his helper were extremely professional and helpful when they installed the new unit. I just can't say enough positive things about them all! When it is so tough to know who is trustworthy enough to hire, it is helpful to know that you can trust Viscarello!!!"

"My AC went out 2 days before a heat wave. I got a detailed estimate right away and signed immediately. The crew showed up next day and worked a long hours replacing all the equipment in the attic. My family was back online just in time to beat the heat. All the staff we worked with were clean, professional , hard-working people. I highly recommend to everyone."

"The young technicians who came to my home to installed the new thermostat and move it to another wall in my home were polite and conducted themselves professionally in my home and cleaned after themselves. I very appreciated Uri suggestion when he recommended to me another alternative at the initial visit and gave me a few quotes to choose from. So I'm very happy with ER service and I would rehired these two individuals back to my home. I will definitely recommend ER to other people in my life."

Water Heaters FAQs, answered by experts

If you want instant hot water and to reduce water waste while improving convenience, a hot water recirculating system is worth it, especially if you find your hot water heater is not hot enough. These systems can save thousands of gallons of water each year so you don't have to wait for hot water at faucets and showers. The upfront investment can be high, especially for systems requiring additional plumbing, but the long-term savings on water bills and added comfort make them a worthwhile upgrade.

Electric water heaters typically last 10 to 20 years, though proper maintenance can extend their lifespan. If your unit is over a decade old and showing signs of inefficiency—such as higher energy bills, frequent repairs, or leaks—replacement is a smart investment. Tankless models last over 20 years, which can make them a longer-lasting alternative to traditional tank water heaters.

Newer models are packed with newer technologies that decrease energy consumption and increase output, giving you more bang for your buck in more bills than one. 

If you’re trying to decide whether you want to repair or replace your new heater, consider factors like your utility bills, repair costs, and even your carbon footprint to help you decide whether it makes sense to buy a new one instead.

You can use multiple tankless water heaters, but that doesn’t mean you should. Adding multiple tankless heaters adds considerable cost to your home in both parts and installation costs. Also, you’re adding many more points of failure in the system, making plumbing issues harder to diagnose. More heaters mean more maintenance, and insurers may want a word regarding the increased risk of water damage. A single, larger unit makes more sense in most situations.

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.
