I have an old 1941 brick Cape Cod house that has never been insulated
properly. I've replaced the incredibly drafty multi-pane lead sash weight
windows with double-paned Andersens and have been gen...
I'm tired of people telling me that there's nothing wrong with my
furnace. There is something wrong with my furnace.
It's a 10-year-old Amana 45,000 BTU, 80% efficient unit in a 1300
square foot ...
I think I understand why new furnaces are more efficient, but why AC?
I finally read an explanation about the exhaust air being cooler, as
low as 90 degrees F from gas furnaces, and more heat extr...

I had to replace my water heater today. The old one developed a leak
somewhere, don't know exactly but enough to make a 3-4 foot puddle every

hoping someone could help with:
a) How does a mo...

Curious as to "fan logic".
I notice that in, say, kitchen hoods, central A/C air handlers, squirrel
cage blowers are almost always used.
btw, does "blower" imply the squirrel cage co...

PBS's World Focus had a little ditty on Denmark energy efficiency -- $15
per YEAR heating bills! Holy shit....
ROI on these systems seems to be about 10 years, whose initial cost is a...
I've often wondered how much of the "energy" is getting lost thru
pressure drop in the hose from my air compressor to the tool. Plus
the thru hole in the fittings is pretty small. Yet none of the

The new energy tax credit appears to apply only to the cost of the
materials, like new sliding doors with energy efficient glass, but not
to any of the installation costs. That limit that can be ap...
Just a hint.
In the winter, my air conditioning ducts, with the AC handler in the
uninsulated attic, let in a lot of cold air. Although there are movable
vanes inside the vents that can be shut, ...

The snow obscures the signal and people die.
