Applications
Sanitary hot water heat pump
The product
Heat pumps PTH employ the thermal energy of the air for the production hot water for sanitary use.
The process takes place in the most efficient and profitable way, with average C.O.P. > 3. The efficiency of heat
pumps PTH allows then to safe guard the environment, making possible a large use of the available energy from
the environment in which they are installed. The ease of installation, the silent and reliable functioning and the
extremely low maintenance needs, complete the advantages of this highly ecological and economic system.
The PTH module 275 produces hot water using the established technology of heat pumps.
Vantaggi

The tank (275 liters) allows to store and preserve heat for a
long time, thanks to insulating shell in polyurethane 50 mm
thick.
LEDs signalling the functioning status:
the green LED indicates the correct
power supply to the device while the
blue led indicates the state of current
delivery to the anode.

Applications
Employ
The heat pump for hot sanitary water PTH 300 is a machine designed to be installed inside the homes. It picks
up heat from the environment and transmits it to the sanitary water. The possible applications are:
Production of sanitary water in the bathing resorts
Replacement of old electric water heaters with 3-fold reduction in electricity consumption
Replacement of old sanitary gas / oil boiler
It can be combined with solar collectors to further reduce electrical consumption
Operation
PTH 300 module produces hot sanitary water employing the established technology of heat pumps. The
principle of operation is as follows:
The refrigerant fluid changes state in the evaporator, taking heat from the low temperature source (air
outside).
The compressor, which represents the heart of the system, increases the energy level of the heat: the
refrigerating fluid in fact, increasing pressure, reaches temperatures close to 90 ° C.
In the condenser it is possible to transfer thermal energy to the sanitary water, heating it up to 60 ° C (in
the version with R134a).
The tank (275 liters) allows a long lasting storing and conservation of the heat, thanks to the insulating
shell in polyurethane 50 mm.

Applications
Matching with other devices
Throught auxiliary heat exchangers, it is possible to
connect the heat pump to alternative sources such as:
•
Solar thermal
•
Boiler
•
Thermalchimney
The standard unit adopts a single-phase electrical
resistance of 1.5 kW. The boiler is made of carbon steel, with
internal vitrification treatment two hands SMALGLASS,
magnesium anode, outer rigid plastic coating (ABS).
The heat pump can be programmed to self-consume
photovoltaic electricity generation.
Great combination with highly efficient solar thermal
collectors.
