"I didn't fully close one of my buckets with the heated down beeswax in it, and sugar ants have gotten into it."get them buggers out of there.........
lol, omni, just kiddin'........they will croak at some point. you said melted down beeswax? so, you just need to refine this to filter croaked sugar ants.
i can't answer your question about a stainless steel solar melter vs. a foam cooler.......anything works really. my solar melters are wood. as far as what window to use? i have used single pane, but had the unfortunate opportunity to use double pane (window replacements with flaws). they work great. single pane works great, just might get fogged or might even crack as rober said. if it works, use it until it doesn't! plexiglass works as well.
electric anything, vs, gas is always good. hot plate, stove top when it comes to messing with beeswax or sugar syrup. it's just messy stuff, (especially beeswax) and can start things on fire. most guys are not to proficient at not making messes when it comes to the kitchen or the wife's kitchen or your mother's kitchen............not saying you aren't but just saying..........
.......
i don't cook sugar syrup anymore for winter feed........i just do no cook sugar bricks, less mess in the kitchen and less labor for me, and works just as good.
for 2:1 sugar syrup, i bring water to just a boil in stock pot, turn it off. line up buckets, dump sugar in, dump some hot tap water in stir. dump some hot water in from the stove top, stir. finish off with cooler water if need be. feed bees. that's it.
works for me, i usually don't have more than 5 or 6 hives. a couple guy beeks i know with more hives use turkey fryers to boil water in, in the driveway, just outside the garage. line up the feeder pails with sugar in and dump the water in. makes their wives happy.........
