boiler

Need advice on sizing a replacement boiler for my home. I believe I need a smaller boiler, however I am not a professional and obviously could be wrong. My contractor is insisting on installing a new boiler of the same size. He believes the replacement must be equal in output to the existing...

Dear Gentlemen, I'll be short: I'm not very knowledgeable in the boiler side of things, although I'm technically inclined and am reading up on boilers as we speak. I have an acute problem, that I have to fix miself due to budgeting issues - I can't afford to change the boiler or anything of...

I don't understand why it's so hard to relight my boiler. It's almost like it's underwater or somthin. I picked up some matches at a restaurant. They had the name of the restaurant on them but I figered that should be okay. If I strike a match and it falls then all I hear is a sizzle and...

hello everyone. I’m a plumber for many years but mostly work in new construction projects. My hot water boiler safety relief valve was leaking. I noticed it stopped leaking and the pressure dropped to 5 PSI. I opened the pressure reducing valve and it brought the pressure way past 30 and was...

Newbie here. I just noticed my Oil Fired Burnham Boiler wasnt shutting off when heat runs. I turned Tstat down so it stopped. Went to check temp and it was almost 200 with pressure rose to 20psi. Normally at 15. I have Hi/Lo set at 180/150 and diff at 12. Maybe I never noticed before but why...

Hi my boiler keeps short cycling .. I think it might be because my thermostat looses its temperature very fast.. if I have it set to say 68 And it’s 67 or 68 my boiler will turn on for a minute then turn off then the will go back on in about 3 min when the thermostat goes down by one ,, can I...

Hi I have a utica natural gas boiler that is about 10-15 yrs old (my guess) Recently bought house and my first concern was that the boiler water gets up to temp which is 180 and shuts off while there is still a call for heat. In my last home i would remember the boiler would run until it...

Hello all new to the forum. I do concrete for a living so bear with me. My expansion tank (plain steel) was leaking at the end of the year from the top, and my boiler also blew a leak. I'm assuming it was a combination of things including my auto fill valve. System was running correctly even...

Hey Guys, I live in Eastern Massachusetts and my home is around 2900 sq ft. I bought this home last year during fall (Built 1988) and my last winter gas bills were skyrocketing. I knew that I had to replace the boiler at some point when I purchased the home but looking at the last year winter...

My baseboards produce 75,000 BTU using 1660 per foot. Three contractors all want to use Viessmann. What negotiating points can I ask for? I'm keeping my two thermostats. How many annual free maintenance calls are reasonable? Isn't $6900 quite high using existing plumbing and gas lines? What...

I am brainstorming how many condo owners have in the past on how to add a water softener when the condo has a central hot water boiler. I understand I would have to have a softener for both the cold water and hot water sources in my condo that come in under the master bedroom sink. Without...

Good morning all, I've been reading these forums for weeks and getting great information from them. My situation is a little different as I have a 1978 tri-level house that has a furnace on the second floor only so we can remove that from the equation, I believe. I know how many therms I used...

Hello all, I've been reading this forum quite a bit in the past week and have realized how important it is to have a knowledgeable person installing your boiler. I'm hoping to get a better understanding of what my needs are so I don't make a mistake. I have an old Weil-Mclain boiler that I'd...

Hi all, I bought this house recently and am still learning the systems. I have a 2 zone, oil-fueled hydronic heat system, and the circulator pump just broke (or rather, is breaking). I have a new one and am ready to install it. My plan was to drain the system from the drain valve (bottom circle...

Hey everybody I've got another question for the amazing people on this forum that will hopefully be easy for one of you experts to answer as it will hopefully be just an informational adventure for me. I've recently replaced the temperature pressure relief valve, expansion tank, and auto air...

My Navien was installed 1.5 years ago and from the start, it had an issue with low-pressure water in the winter. The installer came to fix and it worked fine in the summer, however, in the winter boiler start showing error code E302 two or three times a week. My boiler provides heat to TWO...

Hey all: Several years ago when I had never used Hot Water Heating systems, I asked whether it would be a good move to replace it with Forced Air in our northern Michigan cottage. I am so glad that this forum told me I’d be nuts to do that. We’ve really liked the GWA-105N-I natural gas fired...

I have a Weil-McLain oil boiler, hot water baseboard, and the supply line froze (outside tank, overhead line). This happened last year too, so I had added heating oil additive to this year's tank, wrapped the pipe in heating wire and wrapped that in insulating tape. It still froze this year...

Hi, I'm here as a new forum user and could really use some advice. I have a 12-year-old timber-framed home that is covered with SIPs and has an ICF basement. Very well insulated. Live in southwestern VT about 40 miles northwest of Albany, NY. I have in-floor radiant heat in my basement...

Hi I recently installed a Biasi propane fired conventional boiler. It only has a capacity of 4.5 gallons of water, a far cry from what I was used to with my ancient oil boiler that had a high capacity. How it works is, home thermostat calls for heat and fires the burner, when aquastat reaches a...
