Install Instructions

INSTALLATION OPTIONS
The ThermoDrain is installed vertically, replacing a section of the main drain stack. It transfers the heat energy from the waste water through heat transfer to the cold potable water flowing in the outer coils. The preheated potable
water can then be routed to the cold of the shower, the cold inlet of the hot water or to both of these.
