INDOOR AIR SOURCE HEAT PUMPS
LI MS / LI AS
EVEN COLD AIR IS FULL OF ENERGY
Drawing freely available heat from the ambient air, even
at chilly outside temperatures as low as –20°C Dimplex
LI MS and LI AS air source heat pumps are the cost
effective and energy efficient heating and hot water
solution of the future.
The heat pump is designed for installation indoors, with
air ducts or hoses providing inlet/outlet air from the
outside. For space saving, a built-under buffer tank is
also available.
LI MS / LI AS RANGE KEY
FEATURES:
Range of 2 models with nominal heating capacities of 11kW
(single phase) and 16kW (three phase).
Indoor installation in a basement, utility room or garage.
Air ducting kits provided as accessories.
Complementary built-under buffer tank for space saving.
Operational temperatures from +35°C down to –20°C.
Energy optimised, auto adaptive defrosting cycle.
Variable heating water flow temperatures up to 55°C.
Typical CoP (A2/W35): 3.2 – 3.4 (depending on model).
Supplied complete with wall mountable WPM 2004 Plus Heat
Pump Manager.
Scroll compressor, providing efficient, low noise running.
Economiser, providing high co-efficients of performance.
Electronic soft starter controls to reduce starting currents.

This data characterises the size and performance capacity of the system. For economic and energy consumption reasons, additional factors such as
defrosting behaviour, bivalence point and control need to be taken into consideration. Abbreviations have the following meaning e.g. A2 / W55: heat source
temperature 2°C and heating water supply temperature 55°C.
