The NUOS water heater essentially comprises an upper compartment
containing the heat pump assembly, a module which includes the control
panel and control circuit boards, and a storage vessel.
The storage vessel is internally coated with protective enamel treatment
and is externally insulated by a high efficiency polyurethane layer. The
storage vessel is enclosed within a powder coated steel casing.
The heater element fits into the side of the storage vessel. It is electrically
powered to heat the water to boost the heat pump performance or to heat
the water when the heat pump is off.
The air for the NUOS enters through a round vent at the rear of the unit.
The air could be from within the room or ducted from another room, internal
space within the dwelling or more typically from outside.
The exhaust air for the appliance
can be directly into the room, or,
by using various ducting
arrangements, be ducted to
another room or more typically to
outside the dwelling.
