Heating Help

OH MY!

I checked out that link Murph...these DIYers doing A/C and Furnaces scare the living s**t out of me... I especially ike the guy who installed his ac in 30 minutes...YIKES. soft solder no doubt and no evacuation..just solder and let the refrigerant go...my God! I can't believe this is legal..humidifiers and stats I got no problem with, but when something takes a major amount of schooling and can kill..should be left to the experts. Mike

If you know about latent heat? Simplified its like this...Water can exist as either water or ice at 32°, similarly it can be steam or water at 212°. the difference in the state depends on the amount of latent heat added or removed. SO... if you take 1 lb of water at 32° and raise it to 212° it will require 180 BTU's (remeber: 1 bTU is the energy needed top raise 1# H2O 1° F) To take that same water at 212° and turn it into steam takes 970 btu's...5 TIMES the energy to go from freezing to boiling without raising it 1° in temperature. a 100,000 btu/h can condense almost 8 - 10 lbs of water an hour..thats an additional 7000-10000 btu's just by condensing the water out of the flue gases.. Clear as mud?? Mike

good stuff

Its usually something simple. Its happened to me ALL the time. No matter how careful I am, I get the same thing. Glad I could help. Mike

if ther eis no flame, you have to bleed the line of the air you introduced when you cut into the line. The pilot has an orifice the size of a needle point. #80 or smaller.
