"On October 7th I was happy to have a Navien NCB 240 replace my old heating system and hot water heater, which included carting away the monsterous 40+ year old boiler. Two month's later the system appears to be working well. The house is warm and we never run out of hot water - even with consecutive showers in a four person household - while the dishwasher is on. Precise plumbing did excellent work regarding the installation - and Anthony was professional and courteous in regard to the job. He performed the work at a reasonable price and, perhaps most importantly, took care in performing his work -anyone who walked in a minute after he left would have never known that we just had our entire heating system replaced - this was important to us as the equipment is in an enclosed room within a basement that serves as living space. Would highly recommend Anthony for all your plumbing needs."
