@ May 13, 2014 5:44 PM in Mixing copper and iron pipes for steam? Insulation?

You can purchase the whole length of pipe which is cheaper, have it threaded and with the left over you can come back and just have sized, threaded and pay for the thread job only

I used MTM Metro, fair prices
For supplies they use and I got the pipe insulation from them

Good info to share,

Give Joe a call (JStar), true steam guy, highly recommended and often contributor of the wall, he covers the whole state 908-337-3133, formerly ecuacool, now thatcher HVAC


@ December 19, 2013 5:54 AM in gorton #2 vents issue

I may be lucky, my boiler runs at 1oz or less, from cold start it runs 45 mins to 1 hour uninterrupted until t'stat is satisfied, it only heats up top third of radiators, steam never reaches the air vents

Just an Update

@ December 2, 2013 6:36 AM in Adding a radiator to a riser

It works great, fully heats both radiators at the same time as the rest of the radiators in the house, the tables were correct, 1 1/4" has a capacity of 55sq ft edr and I'm only using 41 sq ft edr

@ November 27, 2013 6:50 AM in Adding a radiator to a riser

It's currently pipe coming from the floor to 90 degree valve, I'm going to try to do it this weekend, the plan is to tee off the riser to the attic and use two elbows before the horizontal 4" pipe that will connect to the radiator

Decisions, decisions

@ November 26, 2013 9:10 PM in Adding a radiator to a riser

On page 8 of the Hoffman booklet shows a diagram for " double radiator branch for riser " which may work if I only use a single branch at top and bottom, seems the extra elbow may help slow down condensate

On a different HVAC blog steam guru Noel Murdough talks about it, so it seems to be doable? (Old post)

Adding a radiator to a riser

@ November 25, 2013 8:32 PM in Adding a radiator to a riser

I have a 11/4" riser that feeds a small radiator 11.65 sqft edr and I'm looking to extend that riser to the attic and attach a 27 sqft edr radiator, according to burnham heating helper page 3 a 11/4" riser has a capacity of feeding 55 sqft, but is this as big to only feed one radiator? or I can combine the two as long as I don't go over the capacity of 11/4" (55sqft) and be able to heat both?

Attic is small and is finished and insulated with new windows and boiler is big enough to cover it, rad Edr will match the room, thoughts?

Piping video

@ November 23, 2013 11:02 PM in Radiator Closest To Return Leaking A lot of Water

Check Dan's video about boiler piping, it may clear any doubts on piping


@ November 23, 2013 12:25 PM in Radiator Closest To Return Leaking A lot of Water

I'm a home owner, but for good performance you could use 3" riser 3" header and reduce when you go down to the eq, or you can go with a drop header for best performance and drier steam, you want to do it only once and drop header is preferred

See a prior thread below where steampro Jstar does a nice dropheader, good luck..


@ November 23, 2013 11:18 AM in Radiator Closest To Return Leaking A lot of Water

See page 15, figure 4.3 or 4.4


@ November 22, 2013 4:58 PM in How Much Can You Downfire an IN5 ?

I'm a H.O. and I did some research for my tenants oversized boiler but boiler broke a leak early this year and had to be change, but check these couple of links

Venting/two stage gas

@ November 22, 2013 12:05 PM in How Much Can You Downfire an IN5 ?

You can increase the radiator vent as well or add a two stage gas valve controlled by a vaporstat, and run on low to match EDR, here is a picture of one of Gerry Gill's installation


@ November 20, 2013 11:00 PM in double vents on a radiator

That was my point, If vents on those radiators are on the big side steam is going to favor them and steal steam from the smaller run out , condensate will also contribute to keep filling those radiators
Just offering another point of view

Over venting? Perhaps

@ November 20, 2013 10:28 PM in double vents on a radiator

You may be venting too fast and there is no back pressure on the system to keep filling radiators simultaneously


@ November 20, 2013 9:29 PM in double vents on a radiator

Assuming you are running nearby close to 0 pressure (maybe you are not) there is a possibility that you have a nearby run out/radiator venting fast and condensing so fast that is drawing steam off the small radiator run out, they both may see steam at the beginning but the fast venting/condensing pulls steam off the small radiator supply
Running at 2,3,4,5 oz of back pressure can be better than 0 this will assure equal steam pressure at all radiators
Just a thought ,

@ November 13, 2013 4:13 PM in Steam help please.. need some sleep!

Looks like you have two returns and both are to tie up above the water line, each have to go below water line then tie into the hartford loop,

Hartford loop

@ November 12, 2013 10:56 AM in New Boiler old pipes

Is your hartford loop connecting to the equalizer? you may need to post more pictures of the returns
