I don't know what you mean by "towers". But whether you live in a tower or a dungeon the hookup's about the same. Here's a little something to help you out,(see images). I've put up two systems one with a dedicated return line and the other using a cold water return, You may move the pump next to the heater if you wish but keep it on the same line. Good luck, Tom
