years ago we worked on a solar project at a university building with a cafeteria....we installed an array of 3 rows of solar powered tubes to generate dhw for the cafe kitchen...the minute the sun came up they were working very well...with it being new technology at the time(steam solar) there was an ongoing problem with maintaining water levels.....we turned it over to the engineers and never found out how it was resolved.....what is the current state of tech. with steam solar , if any???? Thanks , Jack

my 2 cents

@ January 1, 2011 2:15 PM in Problems with new steam boiler installation

i'm just wondering if the boiler was sized right in the first place. did the contractor measure up all the existing radiation and size the new boiler that way and not to the btu capacity of the old boiler. if the water capacity is not sufficient to handle the job you'll get the flooding conditions mentioned in a previous post.....and as mentioned , a good skimming job can take most of a day especially if screwed pipe was used and threading oil and the oil from the cast iron boiler is floating around in there. was that done at the startup????? just my 2 scents........Jack

venting baseboard

@ July 21, 2009 12:45 AM in baseboard heating

most baseboard systems have a purge valve set up to vent all the different runs right next to the boiler . then you set the press reducing valve to the proper cold static press. for the height of the top radiation + 2 or 3# and you're set. no manual venting neccesary . or have things changed since i learned this at B & G little red schoolhouse in the stone ages??????...........old timer Jack
