"Joe came on Thursday and took a look at my old boiler that I wanted to have replaced with a hot water heater since I didn't need the boiler to heat the house anymore. The next day Joe was able to remove my old boiler as well as empty the remaining oil from the oil tank and install the water heater. A few days after the install a crew came and took away my old boiler and tank. I am now getting hot water way longer then I did before and now have more room thanks to the new setup. I would highly recommend Joe."

"We had several different technicians working on installing a new water heater in a crawl space. There were several different unexpected occurrences that arose, but the guys were great. They were respectful, curious, helpful, understanding, knowledgeable and extremely patient explaining our oppositions. They were responsive and prompt to some unexpected situations. Highly recommend them, I'm giving the technicians ten stars for their professional and respectful work ethics."

"I called Pipe Works because the 2nd-floor unit was leaking water from the attic through the ceiling. Pipe Works put in a new unit 4 years ago for the 1st floor completing a fantastic job with no issues so I called them to help with my 2nd floor problem. A representative, "John Sorrentino," came out the same day, and explained we needed to replace the 32-year-old unit, which is what we thought. He explained how we could finance the charges which we needed to do. We also were ready to tell him how our 32-year unit never worked properly cooling or heating the 2nd floor. Before even mentioning this to Mr Sorrentino he already knew the old unit did not have the proper ventilation system and therefore we were probably having issues with the HVAC not cooling and heating the floor efficiently. He was right! We are very satisfied customers with our 1st and 2nd floor units. Their knowledge, expertise, willingness to help the customer and overall service is outstanding. Our experience with Pipe Works has only been awesome. Their quick response, knowledge, clear explanation of work to be completed, explaining charges, caring for required permits, and assistance financing the job. I would not call any other company to handle our HVAC needs."

Water Heaters FAQs, answered by experts

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.

The time it takes to install or replace a water heater depends on the type of heater and the complexity of the job. A professional can typically replace a standard tank-style water heater in one to three hours. However, if the work area is tight, such as a small closet or crawl space, the job could take four to five hours. Replacing an existing tankless unit takes about two to three hours, while upgrading from a tank-style to a tankless water heater is more complex and can take four to six hours. The project will take longer if you are switching fuel sources, such as installing a gas heater which can add about an hour to the timeline, or if the unit needs to be relocated.

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.

Due to the high temperature, using stainless steel vent pipes for your tankless water heater’s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.
