Did anyone ever consider just what the TP system is doing to the pumps? Logically, if you enclose pumps that give off enough heat to keep a 500 gallon spa at 97F in the middle of a canadian winter, then you would expect those same pumps to bake in the summer. Not that I'm biased, I'm just thinking that if you enclose something that makes that much heat, you are probably drastically shortening its potential lifespan. Think of the last time you didn't have proper antifreeze in your car, it overheats and will eventually seize. This goes for the FF tubs as well, if there is no ventilation, your probably changing pumps. Make sure you get a pump warranty in writing!!!
