boiler troubleshooting


my boiler will not raise the temperature above 68* I recently drained the system and installed a new safety valve. Ever since then it just won't get hot enough. Yesterday I noticed that the coupler on the circulating pump was broken and I replaced it. I also checked the zone valve and saw that it was 3/4 closed manually so I opened it 100% manually. I immediately felt the difference in the return pipe temperature. It warmed up considerably whereas before it was cold to the touch. I left the system on overnight and in the morning checked and the temperature was only 67* what could be the problem? i also purged the air from the system.

It hard to help something like this on here. I work on boilers everyday and it can be trip with them. It sound like you have a air leaking in the system. Is there any pipe look like it or had leak. Even if you replace that part for the pump is the pump getting enough amp draw?

It seems to be working ok now. I shut off the fan and the water started to circulate hot both supply and return side. Then I turned the fan back on and it has been running for 2 1/2 hours. Temp rose from 66* to 71* at last check. I am waiting to see if it continues to rise. Thank you for your help!!! chris

The pump maybe going bad. I bet tonight it will stop heating for you. Do a amp draw on it from start to running on the pump. I always replace the pump if is over 10 years old anyways. I find them runnig slower as time goes on with them.

I beat on the door. And tell them its just like going to McDonalds. Ordering food at the drive thu window and then driving off. You either pay, or get arrested for theft of services.

Then ask them, will this be check, cash, credit card, or the police?

i got burned on one after hours call (guy got our number from the phone book...not a regular).Now I don't do them.

I bet Yuri, Been, and John1 got calls from phone book callers.

If you're an independent you can be sure if a regular calls you you won't get burned.

wow! I must say I apologise for my hasty reaction to a lack of responses. I was VERY frustrated at the time. I have been messing with this boiler for close to a month now and the company owner is breathing down my neck wanting to know why he is cold. As a side note. When I came in this morning the thermostat was programmed to run at 65* over night and the temp is 65* I turned it up to 75* and am going to see if, or how long, it takes to heat up the west lab.
Thank you, A Grateful Maintenance Manager.

If you do not know what you are doing, get on a service list for someone who knows boilers. The things can be very dangerous. The National Board of Boiler and Pressure Vessel Inspectors was a client of mine for a time. I have mixed emotions about what they do and how they force expensive inspections. My project was to gather clips from all over the country to put in a slide show for elected officials to watch. Half an hour of picture after picture of boiler disasters, almost all because of no inspection and someone not knowing what they were doing in servicing, repairing or bypassing safety devices on boilers. The body parts of kids blown through glass doors when a well intentioned maintenance person started messing with a boiler system he did not understand were pretty dramatic.
