@ January 24, 2014 12:32 PM in monoflo convection rads house 65 DegreesThe 100 series at 6 ft/hd is pumping 20 gpm. The 007 at 6 ft/hd is pumping 13 gpm. I don't know how to calculate which circ would be best for your application. I'm sure there are some people here that would be capable, but the calculations are like a different language for me.The calculations change depending on the position and quantity of tees.
@ January 24, 2014 11:33 AM in monoflo convection rads house 65 DegreesWhat is the hi-limit set to on the boiler?

must be a straight shank vent"
@ January 22, 2014 12:38 PM in monoflo helpYou 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.
@ January 22, 2014 11:47 AM in monoflo helpOnly the monoflow zone running, are all the baseboards and radiators, on that zone getting hot?
@ January 22, 2014 11:35 AM in monoflo helpWith the flow controls present.Unless you have one, or both in their raised position.
@ January 22, 2014 10:40 AM in Boiler helpSign 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/
@ January 21, 2014 7:07 PM in monoflo helpYou are controlling them as seperate zones, with their own t-stats?
@ January 21, 2014 7:03 PM in Weil-McLain GV-4 Overheatingcalled 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.
@ January 21, 2014 6:39 PM in monoflo helpthat either one of those zones running by itself work fine?
@ January 21, 2014 6:04 PM in Weil-McLain GV-4 OverheatingFor me, the video was not clear enough to see the gauge. Is the hi-limit in the boiler, or on the supply pipe?
@ January 21, 2014 5:46 PM in monoflo helpYou interupted the 1.25" main at the 007, pump the zone back into the main?
@ January 21, 2014 3:10 PM in Weil-McLain GV-4 OverheatingIt turns off the burner at the same as the setting?
@ January 21, 2014 1:41 PM in New main vents, but mains seem unbalancedThe pigtail, always full of water
@ January 21, 2014 1:36 PM in New main vents, but mains seem unbalancedDid they reduce the mains using eccentric couplings?( so as not to hinder condensate)
@ January 21, 2014 1:25 PM in Weil-McLain GV-4 Overheatingstate 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?
@ January 21, 2014 11:14 AM in Hot water recirculation do they save money?Forty Watts? Seems high....746 watts/1 hp.....Taco 007=1/25 hp= about 30 watts
