Hi-Limit

@ January 22, 2014 9:28 AM in monoflo help

What is the hi-limit set to on the boiler?

Control

@ January 21, 2014 7:07 PM in monoflo help

You are controlling them as seperate zones, with their own t-stats?

called it. The circulator may be running, but not moving enough water. When the boiler fires, the surfaces in that heat exchanger get much hotter than your hi-limit setting. They have to, in order to heat the water as it flows across them.

I'll Bet

that either one of those zones running by itself work fine?

Sorry

For me, the video was not clear enough to see the gauge. Is the hi-limit in the boiler, or on the supply pipe?

So

@ January 21, 2014 5:46 PM in monoflo help

You interupted the 1.25" main at the 007, pump the zone back into the main?

OK

@ January 21, 2014 3:10 PM in Weil-McLain GV-4 Overheating

It turns off the burner at the same as the setting?

@ January 21, 2014 1:36 PM in New main vents, but mains seem unbalanced

Did they reduce the mains using eccentric couplings?( so as not to hinder condensate)

Yes

I stand corrected.

state the obvious. For whatever reason, your hi-limit is not sensing the temperature of the boiler accurately. Is the sensor bulb in contact with the well? I'm not familiar with that boiler, and some of the others can weigh in.....Is it possible there is air trapped in the boiler?

Forty Watts? Seems high....746 watts/1 hp.....Taco 007=1/25 hp= about 30 watts

My boss likes to ask me, "How long is it going to take to do that?" My response is usually."Just until it's done". The list of unknown factors that would affect the answer to your question, could take up a wing in the Library of Congress.

might have hit this one. Check the CPH setting on the t-stat.The guess is, and it's only a guess....as the t-stat approaches its set point,it may be opening and closing its contacts.Monitor the voltage at the t-stat connections of the boiler to confirm this is what;s happening.

be east to tell when a return springs a leak, as they are right over the electric. If it were mine, I'd probably repipe the whole basement.There doesn't seem to be enough there that's proper, to warrant leaving any of it.

would add the radiation to the cold room. Balance the over-radiation with flow valves, and take advantage of the colder supply temps. Letting the mod/con handle the heat load of the whole structure. I would, however add TRVs to the bedrooms, if the homeowner liked sleeping in colder temps.

OK

@ January 16, 2014 9:18 PM in balancing the system

If I told you I was going to install a mod/con in an 1800 sq/ft colonial, and I wanted to make it 14 zones. What would you say?

It is wrong

@ January 16, 2014 8:35 PM in Confused

It is mathematics. I don't buy into the new mathematics. It is either right or wrong.

Thanks hot rod

After reading the article, it appears there is a kink in the Universal Hydronic Formula. And now for the million dollar question.......Why won't anyone just say it is wrong?

Conditions

@ January 16, 2014 2:14 PM in Confused

With all other conditions being equal, then can you have a higher DeltaT across an emitter and not have emitted more heat? I am talking design considerations, using two known quantities to calculate the third. Or do you just say, I want more heat over there, so I'll pump it faster?
