Floor insulation ==> frozen pipes???
I'm eligible for a low-income weatherization program.
They want to put insulation in my floors.
It's a ranch-style frame house 40 years old.
Crawl space is closed up during winter.
Outside Temperature rarely dips below 20F and I've never
had any issues with frozen pipes.
But when the insulation goes in, the crawl space
temperature will go down. When I asked about frozen
pipes, the answer was, "don't sweat it, we'll insulate
the pipes." I didn't think to ask about the sewer pipes.
Traps stay full of water.
When I tried to discuss the thermodynamics of the situation,
I got a blank stare.
Insulation reduces the rate of heat flow from the pipes,
but, eventually, the pipe temp gets to the crawl space temp.
I'm afraid that I'll be trading a few bucks off the gas bill for a lifetime
of plumbing problems.
Should I worry about this?
