If you have a dampness problem in the basement, don't let the installers sit
a new furnace directly on the floor. Mortar in four concrete bricks/blocks
to fit under the corners to lift it off the floor so that air can circulate
and reduce the rusting. At some point you may also want to add some plastic
sheets between the steel furnace shell and the concrete bricks to seal any
dampness that may soak through the brick. It will go a long way to reducing
rusting of the metal, you may also want to do the same for your new water
heater if it sits directly on the floor.

Getting a new furnace with air finally........

but the basement has water troubles, the base of the old furnace is
badly rusted.

to facilitate the interior french drain install i am going to have to
remove or relocate my hot water tank temporarily for the drain work.

once finances recover a little i want to replace that heater which
currently vents up the chimney, to a sealed combustoion 95% condensing
heater. shopping for that today. DONT want a tankless!

anyone move a tank successfully? ours s over 7 years old, a 50 gallon
75,000 btu model.

if $ were no object i would replace it too right now but prefer to
wait till later this summer
