ETH is an innovative monobloc heat pump, which thanks to its multi-source option, can achieve extreme efficiency targets as the most energy-efficient source can be chosen each time.

It is able to fully meet any requirement concerning heating, cooling and the production of domestic hot water, operating with outdoor temperatures down to -20° C and producing hot water up to 65° C.
Available in three versions:
M for 2-pipe systems with domestic hot water, in total recovery mode
P for 4-pipe systems, to meet heating and cooling requirements at the same time, in total recovery mode
H for 2-pipe systems with domestic hot water

ETH can be installed in different settings thanks to its small size and its compact lines.

Innovative and multi-source

ETH can use either air or water as a source for the production of hot or cold water. This innovative feature allows users to always choose the most favourable source in any condition of use, to apply ETH in systems with PVT (PhotoVoltaicThermal panels or hybrid photovoltaic panels), or with electrical and thermal energy or in small-sized geothermal systems or with low groundwater capacity. It can be used in thermally altered soils (soils with hot springs) where it would not be possible to dissipate heat in the summer (in this case, air will be used), or in any situation where the available water source can be used but not constantly (as it would run dry). Great value as it avoids having to use two machine.

Total heat recovery

Thanks to the dedicated total heat recovery refrigeration circuit with parallel condenser, ETH meets the thermal and sanitary needs of commercial and industrial 4-pipe systems, without having to reverse the refrigeration cycle whenever a heating and cooling request is received.

Technical overview

Technical specifications

BLDC inverter scroll compressor

The high-efficiency BLDC inverter scroll compressor allows ETW to produce hot water up to 65°C and guarantees operating efficiency in all conditions of use.


The coil has a wider fin pitch and is applied a hydrophilic coating, which prevents the formation of surface condensation and allows the number of defrosting cycles to be reduced by up to 30%.


Electronic pumps and modulating valves, installed inside the unit, are essentially important to ensure flow rate control at constant temperature or constant delta T. Thanks to their control microprocessor, they are also able to adapt to every system need.


Hibox soundproofing of the compressor via a dedicated sound jacket and box, the oversized EC fans with 50% rotation speed and the soundproofing front grille guarantee the highest level of acoustic comfort.

Extra low noise operation is guaranteed by the oversized EC fans with 50% rotation speed, by the soundproof front grille and by the Hibox compressor soundproofing system with dedicated sound jacket and box.
