@ December 6, 2004 6:43 PM in one or two valve radiator: danger of fire in OLD building

That was not even a best guess.Mikes totally right on this. Even if a radiator could get that hot the fire would have started at a closer proximity to the radiator (under it) and on the top side of the floor. Was there any wiring in that joist bay? That fire started in the underside of the floor,maybe a hole in the floor caused the fire to intensify in the burned through portion of the floor,unless the fire department opened the floor up. What is the pipe running closest to the hole? Conduit,Gas? I see the pipe fpr the radiator.

That was 3000 Kwh for the 3 day period. At my residential rate of .08 that pans out to 243.00 for the 3 day period. My house used 1733 Kwh in 30 days. A bad winter could get pricey compared to the old salt trick. lets just say that the county would have a hefty electric bill if "ALL" bridges were done this way let alone roadways.

Thats what I mean buy other areas Dan.But in my eyes a swavy consumer would not limit the ability to heat the dwelling to the emitters being lashed to electricity as a sole means to power them. At least with hydronics you can choose your heat plant to use the cheapest form of fuel and if that changes in the future you can roll with the change as long as it is cost effective. Until electricity can be produced at a cheaper rate maybe never, maybe through the CO-Generation avenue with the use of the stirling engine it could be. I think electric resistance heat of any kind on a residential scale in a dwelling is not going to be cheap until then. We already have it but cost to operate is why its not as popular. Gordy

Being in the bridge construction industry for 21 years,I can say this is a high tech. Cost prohibitive system that is just being studied. Implementing it on a large scale will be tough. A 150' bridge is not squat at 3000 kwh per hour,power consumption. Salt,fuel and manpower is way cheaper over a time period they have to do the road anyway. Also to just do the bridge under the pretense we are preventing corrosion from salts is a myth,the salt will be carried from the roadway onto the bridge. This is not to say that the technology will not have some potential on a smaller scale in other areas, and applications. JMHO Gordy

Wondering what?


@ November 30, 2004 11:00 PM in Combustion Air

I took it as being direct not curt,I like that. Well I have a gas fired Weil McClain. My only thought on this was I have four fireplaces and if I light Two I trip the spill switch on the draft hood if the boiler decides to cycle not good I know. So I went to opening the basement window a crack when burning which solved the problem.Guess I tightened up the house a little more than it liked. there fore I would like to do something a little more automatic. Sounds like your boiler is made to do the modification. Gordy

I'm only asking the question. Not implieing that would be the case.Just a thought I had. Thanks for the info.:)


@ November 30, 2004 5:31 PM in Combustion Air

If we induce outside combustion air say -15* would this not pose a worse condensation scenerio with in a CI atmospheric boiler? Versus using ambient air from the dwelling. I would like to do this also but this was a concern for me. I guess it would be mixing with ambient air somewhat,depending on the setup since it would not be sealed combustion in the true form.

So, did you solve the problem Mark?

Well said John! Funny how in todays society in can pay very well to be incompetent.... With the help of a Lawyer. Gordy

I truley believe Some of us are leaders some are followers but you need to enjoy what you are doing.Be a productive individual to society, and you have done the right thing with your life. I'm still a firm believer in starting in the mail room and working your way up from there in any trade needing degree or not, I feel this produces the most well rounded working individual and it was that way for years. This world was built by the tradesmen of all types,who were Pushed forward by the idealist,and the results studied by the scientist.We are all leading one another in this cycle. This is how society evolves.We all contribute to one another there is no I in the word "TEAM".Now just pick a position thats right for "YOU",and help make this world a better place. Be Happy Gordy

@ November 26, 2004 11:54 AM in 1952 House With Ceiling Radiant Heat

Its interesting to note the piping configuration in my system (parallel). At first when one looks at the main supply and returns, you wonder why they did some things especially on the main returns, but it all has to do with air, I soon learned.After purging Instead of chasing any remaining air around bleeding every loop in a total drain down, it will all come to 2 points on the return in the system. I could not get this in my head for a while because these two "collection points" are in the basement for the upstairs ceiling radiant. Thinking like air in a closed system can be tricky. Gordy


@ November 25, 2004 11:30 AM in Ceiling Radiant heat - copper tubing

So Hot Rod, being that lime is a base that is not playing a role correct. Going by some of the reading in the hot tech topics under "concrete corrodes pipes" here. Thanks for your clarification Hot Rod. Hmmm stray electrical current, bonding ones service to the water pipes per code may have consequences if something is not quite right. Gordy

Nice stuff, I have the Chase brass and copper propaganda with my system. Its interesting to see the point of view back then.


@ November 25, 2004 10:29 AM in Ceiling Radiant heat - copper tubing

You got it. Lots of copper, at least thats how my system is. Looking at the picture I notice a couple of the tubing runs are like new and the majority have a gun blue or black finish to them what is their condition compared to the newer looking?

Paul, elaborate on this reaction a little please. Gordy

@ November 24, 2004 10:39 PM in Ceiling Radiant heat - copper tubing

Exactly Mark. Sounds like a water quality issue, from what I have learned.Notting Mike that several systems you have dealt with did this. Mike are these all in the same area? Same water supply? Its nice to play a little detective work with issues like this ,it helps everyone out. No need for someone with a perfectly good system to tear it out on the premise its going to disintegrate. There are reasons and I doubt its the plaster.
