Re: How to delete boiler coil and replace it with a HPWH
Hi, I've been studying this with Gary Klein and indeed, the cold output. done wrong will damage other equipment or cause moldy areas on walls. Even the manufacturers are taking notice of this. Also do make sure that the in and out airflows from the HP do not mix, or you cut performance by pulling in cooler air.
Yours, Larry
Banging Hartford Loop
Hello to all. Has anyone actually encountered a banging Hartford loop ? All of us here were taught about the importance of a short nipple on the Hartford loop. I do strictly residential work and I have seen endless Hartford loops, with nipples of all sizes and lengths. I have never ever encountered a Hartford loop that had any banging noise. On one of the more recent boiler installations that I did, I deliberately installed an excessively long Hartford loop nipple. It was a mixture of convenience and experimentation. It was something like 18 to 24 inches. Not a sound. Zero banging in the Hartford loop or anywhere else for that matter. Would love to hear about everyone else's experiences.
Re: Makeup water causing boiler failure due to thermal shock
Smith (if there still in business) the last 28s I did which was about 8 years ago they stopped using the blend pump as far as I know. They now provide a "return temperature stabilizer". It is a perforated tube of expanded stainless steel with I think a flange on one end. It goes in the 6" tapping in the back section and goes through the top nipple port and runs the length of the boiler. The return water is now piped to the 6" tapping. The return water flows through the "stabilizer" to all sections so I guess it puts the back section under less thermal shock
Re: Adding manifold help needed
Ed, thank you so much for your help. At least we knew what is going on. My husband tried to contact him but he never answer which made us disappointed. He should says something instead of silence
Anyway, im really appreciate your help

Re: Makeup water causing boiler failure due to thermal shock
I do this on every steam boiler that I am service. Just for clarity, I only service residential. Cleaning is part of maintenance. The eight way will break down the sludge. Repeated draining remove the sludge. Adding eight way after the fact, will greatly reduce the sludge going forward.
Re: Makeup water causing boiler failure due to thermal shock
@ethicalpaul - I don't actually know. This was before I got interested in home heating, it was a poorly maintained rental, and I was vaguely recalling that's what the plumber told us (over a decade ago). I think we just came home from work and noticed the house wasn't heating. I don't recall the basement flooding in the same incident.

Re: Makeup water causing boiler failure due to thermal shock
So all of the fear with Hartford loops etc on steam boilers yet hot water doesn't have it and doesn't even have a lwco?

Re: Steam Boiler Help
Well water leaks will cause the system to use more water but that is about it in the short term. I believe you have other issues that need attention too.

Re: Makeup water causing boiler failure due to thermal shock
If anything I'm amazed at all the comments about dry fired boilers.
