speaking of duisn't dumb, so what a system needs a spare compressor....<quoted text>
God are you an idiot!
Go to page 2 of 2, imbecile.
Here, let me spoon feed it for you:
"Some geothermal systems, though, which are less expensive and less efficient, also need a back-up system that can kick in when it drops below 25 degrees F. to augment a system that may not be able to handle really frigid temperatures."
Most people get a system like this because it's cost prohibitive to get the Cadillac system and the payback period is too long, defeating the purpose.
Here's the link to the second page since you were too frikkin stoooopid to go to it!
God are you dumber than sh*t!
what about a oil furnance system...if the power goes out, your furnance ain't gonna work
when does power typically go out, in real friggin cold weather....
or if your furnance goes on the blink......
same with gas heat system, if your power goes out, it ain't gonna work
the only system that won't quit when power goes out are wood/coal systems
Geothermal systems reduce our dependence on coal/oil/gas, they reduce costs. So they have their drawbacks, everything does. Does that mean we don't use them and work on improving it.
with that attitude, we'd still be riding horseback
