MH and Heat - turning my tank into soup cooking pot?

[Ruth]

I'm having trouble myself trying to decide on a chiller(s) for my systems. My problem is that my house is a one story bungalow with no basement. A chiller is somewhat noisy, and they produce a lot of heat on their own. My house doesn't get that terrible hot as it is log and well insulated but with 6 400W and 2 250W MH bulbs running it definately gets up there on hot days.
Because of where I live it is not possible to somehow have the chiller sitting outside (even if I could somehow figure out a way to build a little shelter for it/them). So you have to consider if you do decide on a chiller it may be enough to keep your tank cool but your room may end up a sauna.
