Reds, Do you have any issues with your grates freezing over even though you have floor heat running? My grates are 1/4" plate steel 16" wide x 8' long with 1" holes drilled in them. With Floor Heat AND when its this cold, my grates will freeze over with ice even though the bay floors are ice free. So I have to close down because of that. And then you occasionally have the person who only hangs the gun up half way in the holder and it freezes solid. It didn't take me long to figure out the little money I get off a few customers it's just not worth the trouble. When I redo my weep plumbing, It will have provisions for blowout! It has to get above freezing before I can make the change! It looks like its going to be awhile.
2Biz,
Before our Airlift Alaskan Polycarbonate Strapeze Overhead
Doors we had some old style fiberglass overhead
doors. Those old
doors were not sealed very good at all. The point I want to make is that on the north
doors ... the north cold wind blew in really bad ... I improvised with some ... low cost ... but pretty strong tarp material from our local Menards store. They come pre-sized with grommets already done & you can add more grommets to get a tighter fit against the
door opening flat surface.. It was a pretty quick process to fasten & unfasten once the permanent fasteners were in place along our prevailing wind
door openings. It is possible ... this type of improvising would give you enough heat loss protection so your grates would no longer freeze & you would also save some on your deicer heat loss. On the down side, you would have to roll the tarp(s) up to store when not used. For a really severe winter, where you need to close for more than a few days at a time ... it could possibly be practical. It certainly would be way less expense than overhead
doors.
Not sure on yours & others "no overhead
doors ingress & eqress" but a temporary car washing routing to the uncovered
door side away from the prevailing winds & subsequent temporary backing out ... from experience ... could potentially work during those specific days that tend to have less business anyway ... than the more calm days.
I hope this is not too hard of a read & makes some potential sense!
