WATER-SOURCE HEAT PUMPS
Adaptability and simple installation
61WG units can be provided with several hydronic kit options, both on the evaporator and/or condenser side, with different levels of available pressure and variable or ﬁxed-speed pumps. If option 153 is selected domestic hot water production is controlled via a built-in three-way diverter valve (not supplied). 61WG units offer water-side cooling/heating reversibility.
A compact high-performance product range
Small footprint, ideal for refurbished buildings, allows access in very tight plant rooms. 61WG: A COP above 5 satisﬁes even the most stringent standards, with a leaving water temperature of up to 65 °C without supplementary system. Variable-ﬂow pumps reduce system energy consumption. The entire range offers low sound levels, allowing installation in any building type. The low-noise option ensures enhanced acoustic comfort (-3 dB(A)). 61WG units are equipped with the latest generation R410A scroll compressor, optimised for typical operating conditions for water-sourced units.
