3.4. Construction features
The HPT300(C) heat pump boiler is basically composed of an upper part (Figure 2.1.-1.)
containing the heat pump unit and a lower part (Figure 2.1.-2.) containing the storage
tank. The storage tank of sanitary hot water – having a volume of (300 l) – is covered by
an enamel coating internally and by a highly efficient thick polyurethane insulation layer
externally, where the latter is covered by the plastic surface of the appliance. The pipe
radiator, limiter, anode indicator electronic unit and magnesium indicator anode are lo-
cated inside the heater. The condensate water discharge pipe branch is located in the
rear part of the above circular tray. The control panel with a display is located in the
front part. All the other parts of the heat pump circuit are located above the storage
tank in a precisely designed order that enables optimal operation, and reduced vibra-
tion and noise emission.
The following parts are placed under an easily accessible and adequately insulated
plastic cover: compressor, thermostatic expansion valve, evaporator, fan ensuring ade-
quate air flow and all other parts displayed on Figure 2.1.-1.
