Raise HW tank onto strapping?
I'm installing a new HPHW heater in my MA basement. Wondering if I should place some leftover wooden strapping or PVC strips below it to create an air gap and avoid heat loss out the bottom? I know they sell those insulating pads, but it seems like 3-4 strips would work just as well (better?).

I don't think you have to worry about it. Water heaters are insulated.

Hot water tanks these days are insulated pretty well. I recently went on vacation for two weeks and as I always do I kill the breaker on out 50 gallon EHW htr and shut off the main water supply.
When we came home I turned on the water and the circuit breaker and put my dirty clothes in the washer on cold water only.
Within 5 min the electronic control on the water heater was up to 120 operating set point so it obviously did not lose much temp in two weeks.
I agree if the basement floor is damp or wet I would raise the heater a few inches and put a plastic sheet between the supports and the tank. Whatever you use wood or cinder blocks will wick water up from the damp floor.
