DAYLIFF HPW150, Installation & Operating Manual

Page: 3 / 32

Dayliff HPW Heat Pump Hot Water Systems are designed for all domestic water heating
applications that utilise the high efficiency benefits of heat pump technology. The integral
systems combine a hot water storage tank with an efficient heat pump that generates
heat from ambient air by utilising the natural heat generating phenomenon of the gas
evaporation/condensation cycle. This is transferred to the stored water by circulation
through a coil type heat exchanger in the tank. Tank construction is carbon steel with
internal enamel coating and a magnesium anode is fitted for cathodic protection against
corrosion. The tank is lined with high grade thermal insulation for heat retention.
Particular features are:-
0 0
• HPW heat pumps work best under ambient temperature of between -7 C to 43 C
• High quality integral heat pump fitted on top of the hot water cylinder with quiet
GMCC compressor that provides a Coefficient of Performance (COP) of up to
0 0
4.16 (at 20 C Ambient temp, 15 C Water temp) and settable hot water
0
temperature of up to 75 C. This provides up to 80% power savings compared to
conventional element heaters.
• Tube type heat exchanger coiled externally around the water tank for performance
and safety with inbuilt sterilising function
• Integral 2kW electric heating element for temperature boosting
• Digital controller for operational and timer settings and fault indication
• Supplied complete with ozone friendly R134A regrigerant gas for optimal
performance
Dayliff HPW systems are high efficiency, high performance water heaters and are the ideal
solution for all residential hot water supply requirements.
