4.2 Heat Pump Leaving Water Temperature (LWT) Selecon
The recommended design LTW ranges for dierent types of heat emier are:
For oor heang: 30 to 35⁰ C
For fan coil units: 30 to 45⁰ C
For low temperature radiators: 40 to 50⁰ C
4.3 Opmizing System Design
To get the most comfort with the lowest energy consumpon with the Heat Pump , it is important to take account of the following
consideraons:
Choose heat emiers that allow the heat pump system to operate at as low a hot water temperature as possible whilst sll
providing sucient heang.
Make sure the correct weather dependency curve is selected to match the installaon environment (building structure,
climate) as well as ender users demands.
Connecng room thermostats (eld supplied) to the hydronic system helps prevent excessive space heang by stopping the
outdoor unit and circulator pump when the room temperature is above the thermostat set point.
