How to install Enduce E1
The Enduce E1 is robust and operates passively, without pumps, sensors or electronics. The product is installed in the floor joists in line with industry rules and standards. The main difference between a standard floor drain is that tap water is connected to the floor drain, partly to allow the heat from used shower water to be supplied (preheat) the cold water to the mixer, and partly to operate the integrated cleaning system that prevents clogging of the heat recovery system. Clear installation instructions are available for download - reviewed and accepted by Safe Water.
How Enduce E1 works
The Enduce floor drain recovers heat from the shower water through a highly efficient heat exchanger integrated directly into the shower floor drain. As used shower water flows through the heat exchanger, the heat is transferred to the incoming cold water of the shower, which is preheated. This means that significantly less hot water needs to be added when showering, reducing energy and hot water consumption by up to three quarters.
