"In late June of 2023, Neo and his apprentice replaced our water heater. Neo did charge slightly more than Google reported as the average price in our geographic area. However, "you get what you pay for." Neo was diligent, friendly, efficient, and knowledgeable. Neo responded promptly to all telephone calls and text messages. There was no drama with Neo. Neo was a consummate professional. We would definitely recommend S&S Piping and Heat. When we experienced a runaway faucet and a broken shut-off valve in the spring of 2024, Neo was quick to respond. Our over-engineered faucet required more than the replacement of a simple washer. In a professional manner, Neo repaired the faucet, replaced the valve, and corrected a related water-pressure problem. As usual, Neo offered good, solid communications. Yet again, we would definitely recommend S&S Piping and Heat."

"I've called Sila before to work on my HVAC unit and realized they offer plumbing services when my tank-less water heater stopped working. They were able to come by that day I called to see what was wrong. Once they were onsite they deterimed my hot water valve stopped working and were able to replace it and got my hot water working in no time."

"Mike Cappuccio came and reviewed our two bedroom garden level condo in Boston's South End to see if a heat pump would solve the heating problems. Electric baseboard heat was expensive and not doing the job. We also could eliminate noisy and inefficient window ACs. We had received a quote from another contractor and were not happy. Mike was able to overcome the issues we had with the approach of the first contractor and his quote was considerably lower.
Our experience with Adam and Dave was superb from day one. They were obviously expert installers and the work was of the highest quality. Every day they cleaned up at the end of the day and you would hardly know they had been there. I work at home and they installed the unit in the room with my office first and I was able to work without interruption after that. They treated our things with care and covered everything when there was any dust around. I would not hesitate to recommend them to anyone.
The system works even better than we expected. The work was finished on the first 90 degree day of the year and we were ready. The system was advertised as very quiet but that is understatement, there is no sound at all. We can't test the heat yet but based on how things have gone so far we are not concerned.
The experience was the best I have ever had with a contractor.

Water Heaters questions, answered by experts

It takes between one and three hours to replace a hot water heater element, depending on whether you hire a pro or do the work yourself. For example, a professional plumber with all the necessary tools and experience can often finish the job in one to two hours, whereas DIY will take two to three hours because it'll involve more preparation and troubleshooting.

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

While a water heater explosion is rare, it is a serious danger. Be aware of these critical warning signs:

  • Sulfur or Rotten Egg Smell: This is a major red flag, especially for gas water heaters. It can indicate a gas leak, which could ignite and cause an explosion.

  • Leaking Pressure Valve: If the temperature and pressure (T&P) relief valve is leaking, it may not be able to properly regulate internal pressure, creating a risk of bursting.

  • Shaking or Rumbling: Loud rumbling or shaking from the tank can be a sign of extreme pressure buildup.

  • Excessive Heat: If the exterior of the water heater feels unusually hot to the touch, the unit may be overheating dangerously.

  • Rust-Colored Water: This can be a symptom of severe internal corrosion that compromises the tank's integrity.

If you notice any of these signs, especially a gas smell, you must act immediately. Shut off the gas supply to the water heater and call a professional plumber right away to prevent a potential disaster.

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.
