"If using an air vent not supplied by Danfoss, it
must be a straight shank vent"

Heat Loss

That's how you size a boiler, to start with.

Pressure

@ January 22, 2014 12:59 PM in Danfoss TRV Help

What pressure is the boiler running?

Heat Loss

You need to do a heat loss, then check the radiation against that,room by room.Stand-up cast iron radiators have very different heating characteristics than cast iron baseboard.This winter has been colder than it has been in lifetimes. There has been many opportunities for folks to see their system under-perform.The changes you made to the system may have had no bad effect.Its just colder than a witches t-t out there.

Only the monoflow zone running, are all the baseboards and radiators, on that zone getting hot?

Not Likely

@ January 22, 2014 11:35 AM in monoflo help

With the flow controls present.Unless you have one, or both in their raised position.

Sign up for Taco's FloPro University. It's free, and they have online tutorials that guide you through the process, start to finish. It will be much easier, if you understand exactly what is involved.I think you'll find the process fascinating, and enjoy the tutorials. Once you have absorbed as much of that information as possible, there are other resources that are more specific to your situation, but these are the building blocks you need first.  http://www.taco-hvac.com/

Hi-Limit

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

@ January 21, 2014 6:39 PM in monoflo help

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

Sorry

@ January 21, 2014 6:04 PM in Weil-McLain GV-4 Overheating

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?

The pigtail, always full of water

Curious

@ 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

@ January 21, 2014 1:27 PM in Hot water recirculation do they save money?

I stand corrected.

I'll

@ January 21, 2014 1:25 PM in Weil-McLain GV-4 Overheating

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.
