Re: Does a 1-1/4" female to 1" male reducer for cast iron radiator exist

That is a inch and a quarter female, by one inch male, black malleable reducing coupling.

Re: Why not use fast vents on all radiators?

I colored outside the box in trying to get my system working. I added a MoM with no orifice installed on the valve side of the rads on the top ends of the runs, essentially acting as an accessory main vent. Steam will get to the near side of the rad ASAP, then after that vent closes, fill at the rate of the regular vent. I'd have done it by adding a tee to the spud pipe as I did to one, but on the others that would shove the rads obviously out of their positions below the windows.

Re: Why would first room off the main line be colder than all other rooms?

@rhodebump You mentioned that the problem room is directly over the boiler room. The boiler room is the room with the real chimney for exhaust. Could that exhaust be the reason that the room directly over the boiler room is having so much infiltration? See if you can find air leaks from the problem room to the boiler room that will explain the big temperature swing.

Re: Viessmann vs Energy Kinetics

For the record I have been using Energy Kinetics products for the past 45 years and absolutely love them. The worst issues I have had were caused by technician carelessness, not faults with the boilers themselves.

45 years ago my wife and I had a System 2000 oil fired boiler installed. We were hesitant spending extra for a boiler relatively new to the market but 40 years later I can attest to its' performance, reliability and endless hot water.

About five years ago I decided that switching from oil to gas heat was best for our family. Our System 2000 boiler was still going strong. I decided to go forward with the Energy Kinetics Accel CS boiler fueled by natural gas. It seemed like a no brainer, Over five years later I can only say I am ecstatic with the performance, reliability and endless hot water!!! We have not had one issue. It runs quietly, efficiently and cleanly. This is a FIRST RATE boiler!!! I do not work for Energy Kinetics and I am not being paid to advertise this boiler.

I have a 100 year old home and our boiler is in the basement. We have cast iron radiators. We use a scale remover coming into our direct hot water heater. We use a dehumidifier in the basement in the summer. Having competent technicians install and maintain these units is the best way to insure their efficiency, performance and long life. I have had ZERO problems with my Accel CS for over 5 years now. Energy Kinetics products have performed above all my expectations. Don't buy their boilers, however, without a trustworthy and well trained technician backing them up.

Re: Room seems to be stuck in a narrow range of 66 and short cycle.

lower the supply temperature. That will slow the swing.

Re: Room seems to be stuck in a narrow range of 66 and short cycle.

Hot water coil needs the boiler to maintain a minimum temperature. the fact that the time it takes to reach that temperature is always 4 minutes just proves the point that it taks one BTU to change the temperature of one pound of water one degree. Every time the boiler drops to the cut in temperature on the water heater limit control it takes the same amount of time to do the same job. with the same temperatures and the same amount of water.

It's temperature … Not Time!

Re: combustion efficiency smoke test

I wouldn't want to clean one

of todays boilers left at a #1 smoke after a year.

In my Combustion book, the new NORA OTM and Aero, Beckett, Carlin, Riello and Wayne's installation sheets (and I won't even go into commercial equipment) the goal for the last 30 years has been ZERO smoke for flame retention designs. Now, if were talking about non-flame retention designs, dinosaurs or dragons, well that's another story.

The CO tester cracked me up though. We can't get most guys today to test the rest, CO on oil, that's a good one!

Re: Piping for New Steam Boiler

You could make a case for the 4" header based on the cross sectional area of the risers. A 2" riser plus 2 @ 2.5" equals 12.92 sq in, and a 4" header has 12.73 sq in, a pretty close match. A 3" header only has 7.39 sq in.

The 4" header would slow the steam down more than a 3", but whether or not it is worth the expense is hard to say.

I would keep take-offs from the header at whatever your mains are and not bother to increase them only to reduce them a few feet away, assuming the mains are sized to the edr.
