"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

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.

Electric water heaters do not need an attached vent, but the location of the water heater should allow for roughly 12 inches of clearance around it. This allows cool air to flow around the appliance and allows repair technicians to work on its components safely. The exact amount of clearance space required depends on your local building codes.

Several signs indicate your water heater may be failing or in need of replacement. Key indicators include:

  • Age: A water heater older than ten years is approaching the end of its typical lifespan.

  • Water Quality: If you notice rusty or discolored water from your hot water faucets, or a foul odor similar to rotten eggs or sulfur, it can signal internal corrosion.

  • Unusual Noises: Banging, rumbling, or popping sounds from the tank often mean sediment has built up, causing the unit to overheat.

  • Leaks: Any water pooling around the base of the tank or visible leaks are clear signs of failure.

  • Performance Issues: A decline in performance, such as water not getting hot enough, taking longer to heat up, low water pressure, or decreased efficiency, suggests the unit is struggling.

  • Visible Damage: Obvious rust and corrosion on the exterior of the tank can indicate a more serious internal problem.

While these signs often point to replacement, some issues may be fixable. It's best to consult a professional plumber to diagnose the problem before investing in a new unit.

Water heater installation code requirements are in place to keep your family and home safe. Water heaters that are installed wrong can simply not work. However, that's an, if you're lucky, type of situation. More commonly, incorrectly installed water heaters pose a real threat from carbon monoxide poisoning, gas leaks, water leaks, and even explosions. 

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.
