Introduction - Baxi Assure Horizontal SHRU Installation And Maintenance Manual

1. INTRODUCTION

Thank you for purchasing the Assure Horizontal
SHRU.
This unit allows the heat contained in the shower or
bath waste water to be recovered and transfers this
heat to the cold water before it goes to the shower
mixer tap and/or water heater device.
There is no contact between the water supply and
the drain water.
The transfer of heat is achieved through a double-
walled copper heat exchanger in accordance with
the regulations EN 1717.
When utilizing the Assure Horizontal SHRU, the cold
water feeding into the mixer valve or heater device is
pre-heated to approximately 20 - 25°C, an increase of
approximately 15°C (depending on the type of
configuration and flow of the shower). The result is
a significant energy saving.
