When I bought my house, I had the well checked out by a well drilling
company for condition and capacity. I didn't get the formal report
until a couple weeks after closing (I was there for the well test, and
so knew from talking to the guy the important things--that the well
supplied enough water for me, and the pump and tank were in decent shape
for their age, so didn't need to wait for the formal report).
Reading the formal report, I was surprised by one thing. It notes the
pump and tank are in a shed (which I knew) that is not insulated (which
I knew) but that is heated (which I did not know). Inspecting the shed,
I see no sign of a heating system. There is a bare light bulb in there,
which I had assumed was to provide light if one wanted to look at things
like the gauge on the pump or tank.
So, the question is, is that bulb the heating system for the well shed?
I've never though of incandescent lights as heaters before, but of
course they give off heat, and in a small shed, I suppose that could be
I don't see any markings on the bulb to indicate its wattage. Is there
a reasonable way to determine what wattage bulb should be used there?
Is any normal incandescent light of the proper wattage fine, or is there
a special type that should be used when the bulb's purpose is heating?
