In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Octogenarian Marries Two Youngsters
This 100+ year old system was originally coal fired, gravity flow. Someone converted it to forced flow, gas fired with this beast 50+ years ago:
The old gal was still chugging along at 472k btus.
The new owners wisely decided that they needed something more efficient after a March natural gas bill of $1,000.
The load calc came to 195k btus with a design temp of 10*. More than enough for Staunton, VA where ACCA specs 14*. It's interesting that the EDR came to 227k btus and when I ran the load calc with a design temp of 0*, it came to 227k btus also. It was common many years ago to use 0* design temp around here. The dead men may have been a lot more scientific than we give them credit for.
We chose to go with two HTP UFT 120 boilers + a 40 gal. indirect. Because we were going with 2 boilers and we also wanted to protect the new boilers from rust and debris from the old system, we made our own LLH/dirt separator/MBR. Don't ask what's inside: it's top secret.
You can choose to do what you want, but you cannot choose the consequences.
