"When our existing water tank started to falter we knew we needed to upgrade. Derry Plumbing and Heating installed a phenomenal tankless system for our 3800+ sq foot home and we never had a reason to complain. Our energy costs went down and we always had hot water for our family of 5 and numerous guests."

"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."

"After the referral through Sevice Magic I also received a personal reference from a friend of mine who has done business with Thorp Thomas at Heat Kits. I knew immediately upon speaking with Thorp while looking at my failed boiler that he would be the Technician I would use to install a new water and heating system. His knowledge of both old and new systems is incredible, and the actual work product once the system was installed was of very high quality. I have already referred Heat Kits to two of my friends, and have every intention of referring him to anyone else I run into who may need any plumbing or heating needs. Although the lowest price was not a major deciding factor of who I chose to install my new system, I did find in the end that Heat Kits was the highest quality and workmanship for the most reasonable price."
