PROBLEM: I have an old oil steam boiler that also heats the water. I am
concerned about sealing the basement too much in my quest to save on energy
I've read about carbon monoxide poisoning. I also have a gas dryer and two
bathroom fans. All of the above four items could one day be running.
I experimenting with bringing in air at this time, but the air isn't warm
when it comes in. I also made a damper for the four inch pipe.
I saw another post about a device that heats the air to room temperature.
I wonder if I can do it myself.
PROPOSED SOLUTION: I propose putting the 4" pipe upto a steam pipe next to
the boiler. The boiler is always warm because it makes our hot water. I
would enshroud the pipe so the cold air coming in would pass the pipe and
take the heat. In the summer, I propose one of those dryer diverter pipe
kits so the air would not pass the pipe area.
My concern is not so much the extra cost of heating the water as a result of
the cold air, but the possible contraction of the pipe with the cold air. I
wonder if it would crack? The steam pipe is made of steel. The length of
my air pipe is about 15', so it could pick up some warmth along the way.
What do you think?
