The little giant and hydrothruster won't be a whole lot louder than a Danner, but yes they are somewhat expensive. As to Danner failure, I've never heard of that before. I know on my old Danner 5 (ret.) the impeller housing would crack if I looked at it funny, and it was loud, but other than that it was a good pump. As to adding heat, these pumps are far more powerfull than the little things we normally use and therefor use much more power, however they all have metal motor housings which act as heatsinks, and I'm sure you could further cool them by adding a low CFM fan to the back of them....just a thought.... Still the big Danner should do well here but it won't give you the PSI of the big boys.
