4.2 Modular Chiller Leaving Water Temperature (LWT) Selection
The recommended design LTW ranges for different types of heat emitter are:
For floor heating: 30 to 35⁰C
For fan coil units: 30 to 45⁰C
For low temperature radiators: 40 to 50⁰C
5.3 Optimizing System Design
To get the most comfort with the lowest energy consumption with Aqua thermal, it is important to take account of the
following considerations:
Choose heat emitters that allow the heat pump system to operate at as low a hot water temperature as possible whilst still
providing sufficient heating.
