Even .14 per day seems ridiculously low, but the math is correct, according to the link. Apparently chillers have become much more efficient in the past few years. I knew they were getting better, but I didn't think they've gotten that good. Of course this is if the site's conversion is correct.
I assumed that your math statement was directed at me, so I'm sorry for taking offense.
I run a 2100sqft home, with a pool, and also do not have the luxury of cooling a single room with a window AC
unit. I was just stating that they are similar pieces of equipment.
In my original post, I was just trying to convey, that when factoring the initial cost of such a unit, with operating costs, it would take years to see any savings through your power bill.
It's very hard to figure out, what running my AC
3 degrees cooler, costs. I couldn't even knowledgeably speculate, but I can't imagine that it makes much of a difference. Down here, it runs most of the day, no matter what.
I would like to have one, but for me, with a 200+g system, the initial cost is difficult at best, and the AC
route, is a feasible solution.
