Water heater pad
My HPWH is going in a tall crawlspace and I want to protect the base. Since it is going in before the crawlspoace is conditioned, I was thinking about using a condenser pad, but most of those top out at less than 400 lbs or load and my water heated will weigh roughly twice that when filled.
I found the Insulfoam water heater pad, but it is not available online from what I can tell.
What alternatives are there?
Also, since this is going in before the conditioning of the crawlspace, I was thinking of putting some thick plastic sheeting between this and the drain pan to allow the contractors something to better seal to. Is this a good idea? I am concerned that a seal to the pad will not be as good as a plastic to plastic one.
