INTRODUCTION

Rheem Thermal Water to Water Hot Water Heat Pumps are available in sizes from 23kW to 352kW
nominal output. The units are manufactured as water-to-water or ground-coupled design.
Each unit is a fully packaged unit, requiring only electrical and water connections to be made on
installation. Circulation pumps are required for both hot and cold water sides of the system; these are
not supplied and should be sized to ensure water flow specified is achieved.
Each unit is factory charged, with refrigerant R407c being ideally suited for commercial or industrial
situations requiring hot water up to 61C. Rheem Thermal also manufactures hot water heaters with
R134a for 65°C.
The Rheem Thermal heat pump is installed to a wide diversity of commercial and industrial applications.
The performance of the unit varies with ambient operating conditions, water flow, and water temperature
and as such, selection should be done in conjunction with an experienced heat pump dealer or the
manufacturer.
Rheem Thermal units are custom-manufactured to meet specific task / site requirements and a wide
range of options is available in unit design.
This manual includes important information in regard to installation, operation, maintenance and
servicing and should be retained for the life of the heater. Correct installation and familiarity with the
operational guidelines is important.
Caution should be taken if soldering to avoid damage to thermostat sensor. Sensor should be
removed prior to soldering and refitted once the pipe has cooled. The sensor is located in a well on
the return water pipe.
