"We needed our boiler replaced and had multiple companies come and look at the job. We ended up selecting Sila as we read good reviews on the company. Sila surpassed our expectations. The tech who performed the install (Gage) was on time, communicated the entire process to us from start to finish and did a tremendous job. He also made sure to clean up afterwards and was very professional. We would absolutely hire Sila again!"

"This company has been awesome. I am a Worcester resident and have no clue about heating systems. David Clay and his team came out to look at my boiler. It was not firing. Winter is fast approaching. David provided a free estimate and also encouraged me to look at quotes from other competitors. I did. And his pricing was best aligned with my budget. His quality of work is amazing. David and his technicians fielded all my questions- I had many. Their customer service is amazing as they had all the patience and courtesy to educate me about the work and boiler systems. My experience as a customer is that Clay Plumbing Heating offers the best quality, professional craftsmanship, best client service, and at the best rates."

"I originally called the company that did my regular maintenance less than a year ago. They told me they couldn't send someone out for 3 days! This in the middle of a cold snap. When I called Rodenhiser, they were able to send someone the next day. While they were not able to completely fix the problem right away - a part was needed - they were able to restore heat while we waited for the part. They came back in a few days and repaired the boiler zone controller."

"I needed both the oil tank and the oil boiler replaced, plus an indirect water tank installed. Got multiple quotes and I went with NV Heating as the quote was reasonable and the boiler/oil tank/water tank were all high quality with great warranties. Installers were professional, timely, and courteous. Highly recommend."

"Philip and his crew did such a wonderful job installing a new heat pump system in my home, I later hired them to install a power vented hot water heater. Philip and his crew did an excellent job, which included venting the unit up directly through my roof (since venting out the side of the house was not an option). I have great trust and confidence in Philip and his crew. They are timely, professional, skillful, and know what they are doing."

"Tim P, Generator Advisor, visited our house and gave on the spot estimatesâ ¦..he was GREAT. Licensed Electrician who knew his business and was easy to speak with. Timely communications and responses to text messages! Tim was helpful answering questions after the generator was installed. We talked to 5 Generac dealers and a Kohler dealer. Cotti-Johnson had the best pricing in the South Shore area. We highly recommend this company. If you are thinking about buying a standby generator, Cotti Johnson is the company to callâ ¦..Art V"

Install Boiler questions, answered by experts

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

Costs range from $3,000 to $7,500, depending on system size and efficiency.
