"Alec from Aqua Sewer & Drain Service very professional when he showed up to check the water leak we had. Alec diagnosed the issue and said we needed an expansion tank since it cracked and that’s where all the water was leaking from. He said we don’t need a water heater because that is functioning properly. He took some pictures and then went to get the parts and came back within 30 mins and started the work. You can tell he really knew what he was doing. He had all the right tools in his work truck. He removed the old expansion tank and put in the new expansion tank and a shut off valve and he also strapped the expansion tank so it got added support. He also check the water pressure and looked for leaks before he left. We had this issue Friday night around 11pm and we call his company Saturday morning and he should up at 8am. It took about 2 hours before he finished. Alec was very knowledgeable, he also wore booties on his shoes in our house. I would recommend Aqua Sewer & Drain Services to anyone who has any plumbing issues. We live in South Brunswick NJ."

"When we were short on hot water and our furnace was on the way out, I contacted the The SaveGreen Project. They provided a list of contractors, and after numerous calls finally got through to a contractor that understood the program. Greg thoroughly explained the process, and even walked me the process, guiding us through from initial application process to final walkthrough. When Greg came out to assess our situation, he was very professional and extremely honest. He offers the best prices and uses high quality brands. His experience speaks for itself, he was the only contractor who told us we can install a tankless water heater. Additionally, he was able to help us with our failing furnace and provided one of the top systems for an extremely reasonable price. His staff is professional and clean. They put cover grip cloths to protect the floors, and were very careful when handling the equipment. Before installing the furnace and air purifier he performed a full duct cleaning. His staff was nothing short of excellent; they team showed up on time, worked efficiently, and the results speak for themselves. The level of communication speaks for itself, any questions or concerns we had Greg took the time to address and ensure we were completely satisfied. For anyone in need of plumbing, electrical work, or for any HVAC service, I highly recommend Greg and his team."

"Called Home Depot at 6:03pm on Saturday 2/26/22. At 6:30pm Arctic Air Conditioning contacted me, had me take photos of my broken hot water heater. 15 minutes later, Katie from Arctic called me back with a more than fair price and worked her magic to get me an install for Sunday 2/27/22 at 2pm. Alex from Arctic arrived Sunday around 2pm and started the project. Elijah from Arctic arrived 45 minutes later and by 6pm ( 24 hours after my initial call) we had a new hot water heater up and running. Great experience, Alex and Elijah were professional, knowledgeable and courteous."

Water Heaters FAQs, answered by experts

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.

The right way to vent a gas water heater is to have a pipe directly upward or slopes upward out of the house. Because hot air naturally rises, this type of venting will efficiently ensure that all gas moves out of the house. Your system may rely on fans or blowers as well.

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.

Flushing biannually, checking the anode rod, and temperature settings maximize equipment lifespan while reducing surprise costs.

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.
