My Burnham MPO boiler was installed in August. I've an indirect water
heater attached as well. The domestic hot water works fine and heats
up on demand as expected. Now that heating season has begun, I find
hydronic system with very very weak heat output. The new circulator
is running fine. The manual says there is a 15degree differential
between the "high limit setting" and a call for boiler ignition. I
see the high limit is set at 200F. I raise the thermostat to call for
heat, but I watch the boiler thermometer go down to under 90deg F and
never come on. The only way it does come on is if I run the hot water
Any ideas or suggestions on what is wrong would be appreciated.
Thats too bad , maybe you could pay him a visit in person ?
its really hard to diagnose a problem as yours over a keyboard
heres some obvious things , then you'd better consider getting somebody over
there who can figure it out without damaging it or your property
1. boiler piped properly ?
2.circulator installed properly ? there will be an arrow on the cast iron body
indicating direction of water flow , the arrow should be pointed toward the
direction of water that will take it into the bottom hole on the boiler .
3, air , tony mentioned it , but you could still have air trapped soemwhere
can you hear water flowing through your radiators
all my other ideas involve electrical and low voltage wiring , which i wont
get into with you ,
the three things i mentioned above are easy and involve simple visual
see what you can find out , otherwise and unfortunately you may have to pay a
competent boiler tech to suss out your problem
Call around to the various suppliers for that particular boiler, and tell
them whats going on. Ask them if they know what happened to the installer.
Also ask them who's the best tech they got and go from there.
No its not gonna be free, and probably not gonna be cheap. Just consider it
the offset between the lowest bidder, and having it done by a *competent*,
licensed, insured, professionally trained, HVAC technician.
He should be easy to spot: clapped out bondo Pinto wagon hooptie with used
parts in cardboard box, ladder on roof bigger than hooptie, broken jamb
material and majik undies fluttering from a loose piece of trim.
Tekkie Don\'t bother to thank me, I do this as a public service.
In other words you have nothing to say about helping solve the problem but
you feel free to attack the original poster by assuming that his choice was
price driven. Most definitely abusive.
Now you'll come back with an attack on me. It never fails. I post and you
dance. You'll just have to dance some more monkey boi. Dance boi, dance.
Asking questions is now 'abusive'...
Boy, you're one clueless mother fucker.
I feel like abusing you a little...
What content of your post 'helped' the original poster?
Now you can post a clueless reply as always.
