@ December 28, 2004 2:32 PM in flying heating equipmentI don't know if this is sarcasim. But you act as though an unsheltered life is supposed to be filled with danger. Sounds like your boss shoots from the hip. Sometimes you have to draw a line in the sand. This instance puts everyone in the vicinity in potential danger not just the guy doing it.

@ December 27, 2004 12:52 PM in methodology question concerning gas consumptionGood point! Another variable, that One can't control. That makes a big difference. Starting to wonder why I bother keeping track, I went through the last two years of gas consumption, NICOR keeps a running tab on your consumption for two years on their web site. My average was 5.11 Btus per HDD per square foot. 1880.00 total, for heating over the last 24 months, thats a before tax and fees figure at .6159 per therm avg. Taxes and fees brings the therm cost up to .7854 for a 2358.91 total for the period. I figured it costs me .1680 with fees per HDD to heat the house. Highest gas bill in the period was 251.00 for that 24 month. I don't think thats to bad for a 83% boiler and 3950 sqft.(including basement) of conditioned space at 72*. As close as I can get Gordy
@ December 25, 2004 6:44 PM in methodology question concerning gas consumptionI'm just a homeowner Gerry,But that is what I used Degree days. You can break it down as far as Btus a sq. ft. This will work if you have the gas consumption narrowed down to just the heating plant. The only variables will be wind,infiltration,solar gain. Its so hard to weed out all the variables. How many times you enter exit dwelling,wind speed,wind direction,solar gain,lack of solar gain,light usage,cooking heat. Gordy

@ December 24, 2004 4:06 PM in foam insulation questionDura Slate, I looked into that product, its the same material we use as a bearing pad under precast box beams in the bridge industry, we use to say that the material would make a heck of a shingle and walla. Very durable product I was surprised by the warranty only being 50 years though, should be 100 years. At a starting cost of 200 bucks a square, and only providing an additional 20 years warranty compared to asphalt architectural they were a little out of my budget. You should be quite happy for many years "life time". You are quite right about asphalt being the heat sensitve roofing material as compared to the other options. Though it should still be stated the importance of ventilation for a roofing system " of ashpalt nature" since I would say a high percentage of homes are indeed asphalt roofs. Warranty well you are right about the prorating, amusing indeed, goes to show you most manufacturers don't know how long their asphalt roofs will perform. No matter how much you do right by their procedures. Southern exposures always the first to go. Although I have seen some go to hell in 10 years a little money is better then none at all. Gordy
@ December 22, 2004 1:00 PM in foam insulation questionWhen the roofing material prematurely fails, don't even think you will collect on any warranty from the manufacture with out proper ventilation fact. Catch 22 You won't find data from the manufacture indicating a "maximum" acceptable attic temperature either. I don't care what reading material is out there disproving the need of roof ventilation,in the end when the shingles fail it is the manufacture that you will deal with and they do not disprove the need for proper ventilation. Remember hot flows to cold, so any delta t you create on the backside of the roof surface will enhance the dissipation of the heat build up, some is better then none at all. When I replaced my old roof you could tell exactly where the hot spots were. The original attic ventilation had no soffit vents and two gable vents, because original roofing was cedar it did not make to much difference.The reroof was fiberglass shingles and ventilation was not enhanced roof failed in 15 years. Since I have moved in and installed a new roof this summer and changed the ventilation. It makes a difference. In the case of spraying foam on the backside of the roof, fine but you should have a 2" gap between the foam and the plywood with continuous soffit and ridge vents. Air circulation in each rafter bay is key. Gordy

@ December 22, 2004 10:29 AM in What's the right amount of Delta T?Mark in a radiant system there are several delta t's. In a mix down type application there is the following delta t's. Main return and the boiler supply. Main return and mixed down supply to the radiant loops. The loop supply and return. The fluid and pipe wall in the loop. The pipe wall and the medium the pipe is imbedded in. The medium and the room Temp. Which of the these delta T's do you find most important? I know it sounds a little crazy breaking down some of these "micro" delta t's. Just wondering if anyone considers these and which they pay the most attention to. Gordy
@ December 18, 2004 6:41 PM in Efficiency vs. EconomyHere, Here. A mans home is his castle. I will be darned if, I will roam in my castle in slippers and a sweater. Comfort is the rung above efficiency for me for now that is. Finding that fine line of both is the key.
@ December 18, 2004 1:14 AM in Efficiency vs. EconomyLarry that is exactly what I'm trying to decifer. I don't think there is anything real concrete to go by that I have seen. I know I will save money, the question is how long is the pay back going to take and is it worth replacing a boiler that has alot of life left in it but not as efficient 82% in my case. I guess the enviroment is an arguement and if the cost of fossil fuel spirals upward it will become more worth it. I think it will be hard if not impossible to have a formula that fits every case. I only say that because everyones envelope is a little different, and the types of radiation, fuel types. The only true way would be to install the new boiler and compare the efficency with your old one. I think if the manufactorers can come up with a concrete formula they will sell alot more boilers high efficiency ones that is.
@ December 17, 2004 8:11 PM in work bootsI used to be in that train of thought. I could buy 4 pair of cheap boots, for what I would spend on a pair of Red Wings. Just try a pair forget about the money you won't be sorry. You only get 1 pair of feet. No breakin period comfortable. I use to go through 3 or 4 pairs of cheap boots a year. I get a year and a half out of my RedWings. I also got a discount for being in the union, saved me 35 bucks. Darn near a cheap pair of boots. Gordy
@ December 16, 2004 10:20 PM in Gas BillSee thread "1 st gas bill with new Vitodens". Mike figured Btus per degree day except he did not break it down to btus per square ft. He would be at 4.92 per square ft I'm at 4.74 before knocking off what goes up the stack. My square footage includes all areas where there is radiant so I have a portion of my basement in my calcs.

@ December 16, 2004 10:00 PM in Gas BillPretty simple actually Mark. Single T-stat for dwelling, One B&G HV circulator for whole system, simple boiler bypass with a taco paneltrol mixing valve, and one "GROSSLY" oversized WM CGM 7 boiler,but lets not open that can of worms. That would be a thread "always do a heatloss calc." Ceiling radiant and floor radiant emitters. System temps are 100* supply after mixing valve,upper 80's return in the shoulder season. when it gets down around design it will run 115* supply and upper 90's return. I came up with a 89000 btu heatloss with slant fin,I think its even less than that. I don't know where the guy got his numbers for a 172000 btu boiler from. Well I do but thats another discussion. Thanks Gordy
@ December 16, 2004 9:34 PM in Gas BillI'm just trying to get a handle on how my gas consumption fairs to a more modern radiant system, or not so much the radiant end but the boiler and controls. Trying to decide on upgrading to a condensing modulating boiler, but will it warrant removing a perfectly good operating boiler at present. So what I'm trying to come up with here is a comparitive number "Btus a square foot per degree day" that could be an apples to apples approach. It twas early this mornin in my thinking so bare with me. I could deffinitly be at the wrong pew. I know what I'm consuming with the water heater and the Gas Light which thats all I have besides the boiler on gas.So is there some other method to kinda give an up front idea of savings with older boiler versus condenser. I have seen alot of % thrown around after the install. Gordy
@ December 16, 2004 5:49 AM in Gas BillI recieved my gas bill for the 60 day period yesterday. 330.95 therms total and 1062 degree days for period. 330.95-133.2(therms for water heater and gas light)=197.2 therms dedicated to my boiler. 197.2 therms / 1062 degree days =.186 therms per degree day .186*100,000=18,600 Btus per degree day. 18,600 Btus per degree day/ 3925 sq.ft. conditioned space=4.74 Btus a sqft. per degree day. 4.74-18% for the Gross boiler input=3.89 Btus a sqft. per degree day. Would indicate actual heatloss of the dwelling. Does this seem like the right approach? If so is 3.89 Btus sqft.per degree day a fair number for gas consumption? Thanks for your help Gordy
@ December 16, 2004 5:20 AM in I'm stumpedKinda like walking into the containment vessel at a nuke plant, -35 to 74* aHHH the radiation is so soothing. ;0
@ December 15, 2004 1:17 PM in I'm stumpedAre the two rooms on two different loops? Could it be air in the loop that is 10* cooler? you can still have flow and have identical delta T. Are floor coverings identical between the two rooms?

@ December 14, 2004 11:21 AM in Dan Peel has died (Dan H.)I'm So sorry for your loss! although I never personally knew Dan, I was always eager to read his posts on what ever subject it was pertaining to,he had a hand in helping me learn and probably never knew it. What a man, my eyes well as I read these posts. What an honor to be missed by so many. I can't imagine leaving this world in a better way then to be remembered by so many elite colleagues.His words will be missed and his presence. The Kaske family
@ December 6, 2004 9:55 PM in one or two valve radiator: danger of fire in OLD buildingProves Mikes point. The power of steam is truly amazing in the right conditions though. I got to witness first hand while working at an outage at a nuclear power station. Worked on the turbine deck building scaffold for the fitters. Saw 36"dia.X 4" thick wall stainless steel pipe elbows that looked like a tiger clawed a bar of soap, the pipe erosion was incredible. One pin hole and run your hand acrossed it at that kind of pressure it would cut your fingers off and cauterize the stubs in one pass.
