My boiler is acting up. I see that sometimes the glass gauge

My boiler is acting up. I see that sometimes the glass gauge get full, then I shut off boiler, drain about a quart of water and turn it back on. Lately glass gauge set a half full, and when boiler fires up it will bounce a little. I also see drops of water falling from the top of the glass gauge but not that many. I don't know if I have a automatic shut off valve for too muck water, so that is why I shut down the boiller when gauge is full because I don't want boiler to burn out. Your help appreciated.JA: How long has this been going on? And how severe is the problem?Customer: Boiler is 3 years old. Problem just this winter. Also have mild banging in pipes. Also, temp set at 72. At this temp all radiators EXCEPT the back bedroom operate and also the 4 Risers do not operate. But if I turn the temp uo 4 or 5 degrees, them all radiators and Risers operate. Had the radiator flushed with chemical cleaner 2 months ago and also have had numerous plumbers in but all give diferent answers.JA: Do you plan on doing the work yourself?Customer: NO my problem is I have had 4 plumbers in: one wanted to repipe eveything for $5,000, others said it could be a variety of other causes. Reading your blog, I see blowback mentioned many times. Is that something I could do?JA: Anything else we should know to help you best?Customer: This past Saturday(a cold day) gauge was full so I shut down the boiler mid day. %pm turned back on and all radiators and risers miracleously heated up. Shut dowe 6:30, back on at 9pm, off again at 11pm. Same sequence on Sunday and all radiators and risers worked. Because these were cold days, it seems the boiler had to work harder and maybe that was why all the radiators and risers worked? Today is mild out, so back to one radiator not getting hot and only 2 of the four risers getting hot. This a clue?

Nest thermostat, fan will not come on during heating. It

Nest thermostat, fan will not come on during heating. It comes on automatically when cooling and can be manually operated from the thermostat and the Nest app. It just won't come on when I call for heat, causing the temperature not to rise. There was no problem with my old thermostat. What could be causing this?

I have a Toyotomi OM-180 that is being used as a boiler for

Hello,JA: Hello. How can we help?Customer: i have a Toyotomi OM-180 that is being used as a boiler for baseboard heat. There is a pump in the system for circulating the hot water that is wired to run all the time. The temp on the unit is set at 130*. The wall thermostat is set at 65*. The unit fires up, runs for about 22 seconds, then shuts down. It starts back up again a few minutes later, and runs for 22 seconds again. It does this non-stop, never running for more than 22 seconds. The temp at the wall thermostat never gets up to 65*. It's like the heat system can't keep up with the outside temperature, but the unit is cycling off. The temp gauge on the outlet side of the unit shows 130*. The inlet fitting seems to be the same temp by touch, though the is no gauge there. The piping to all the baseboard radiators feels warm, as do the radiators. This house is new to me. I am told that this is how the system has always been whenever it gets below about 30* outside; that the unit cannot keep the house warm. Seems to me that if the unit itself is getting up to temp and cycling off, then there is excess heat available that is somehow not getting into the house. Ideas?JA: Did you double-check the thermostat's settings? And what about the filters?Customer: You mean the wall thermostat? Or the one on the unit? Which filters? Air? Fuel? Not sure where the air filter is, if there is one.JA: Do you plan on doing the work yourself?Customer: Yes, as I'm in a remote area of Alaska and d't have another option. I am an aircraft mechanic, but with limited knowledge of HVAC.JA: Anything else we should know to help you best?Customer: I think that's it for now.

Our original 2 story house is 78 years old. We added a

Our original 2 story house is 78 years old. We added a Master Bedroom (MBR) Suite (24 feet X 18 feet) over the unheated one car garage. It has 3 exterior walls. The whole house (except for the sunroom which has hot water heat from the same boiler) is on steam heat. The problem is that the MBR is cold. There are 3 radiators in the MBR: 2 in the bedroom and 1 in the bathroom. They have new large size vents. The thermostat is in the first floor living room which is on the opposite side of the house from the MBR. It can be 8 - 10 degrees colder in the MBR. What can we do to get the bedroom warmer? BTW, the full basement is very warm. Thanks, Janet

My residential boiler has no name plate, etc. - removed by

My residential boiler has no name plate, etc. - removed by others -. I believe it is a 137,000 BTU Burnham boiler at least 30 years old with 6" power assist vent on right side. On the left side of the unit is a cast iron fitting coming out of the boiler jacket with an adjustable aqua stat on top set at 180 F degrees. The boiler will heat up and run for about 3 minutes and shut off. We replaced the pump to no avail. This fitting on the left side is very hot. I removed some piping to get at this fitting. I could reach into this fitting and it feels like there is a thermostat like a car radiator thermostat. I can't break the 2" hex fitting on the top with out some major work. My two 24" wrenches were not enough and looking for my 2" x 3/4" drive socket set to try to open up this inspection cover. If, indeed, there is a automotive style thermostat in there where do I find replacements. It appears to keep the not water in the boiler and is not opening to let that boiler hot water out. Am I on the right track and can you recommend a web site to get either a replacement internal thermostat or the entire cast fitting? I tried to send a picture here of that cast fitting but apparently this question box will only take text. Thank you, Bubba /Users/virginiaharmon/Desktop/IMG_5401.jpg/JA: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?Customer: I believe it is totally related to that internal thermostat.JA: Do you plan on doing the work yourself?Customer: Yes, but am not averse to asking for professional intervention.JA: Anything else we should know to help you best?Customer: Any way to send you a picture?

I have hot water heating and domestic hot water (DHW) both

I have hot water heating and domestic hot water (DHW) both fed from a gas fired high efficiency heater. Its a pretty old system with 6 zones - some 100+ years old, some from more modern times. The other day I had a burst pipe in one of my zones and I had a plumber repair the pipe and they purged the air in the radiators in that zone.A day after my hot water stopped being hot and I went to check it out. From feeling the pipes I figured out that the flow into the DHW was getting stuck. The pipe into the circ was hot but from the circ into the DHW tank was cold. I checked all the electrical controls and everything looked good. I could also hear the circulator running and the motor casing was hot.On a whim I hypothesized that maybe it was just "stuck" somehow (think I read that somewhere). So I opened up the drain valve on the system and hoped releasing the pressure would do something. It must have because when I turned everything back on I could hear water rushing through the circ and the flow was restored.Problem is that this happened again a few days later so whatever I did was only temporary. Opening the drain again resolved the problem the second time...Any suggestions?
