4.2 M thermal 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 
 
4.3 Optimizing System Design 
To get the most comfort with the lowest energy consumption with M 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. 
  Make sure the correct weather dependency curve is selected to match the installation environment (building structure, 
climate) as well as ender user’s demands. 
  Connecting room thermostats (field supplied) to the hydronic system helps prevent excessive space heating by stopping 
the outdoor unit and circulator pump when the room temperature is above the thermostat set point.
