Ferroli Omnia ST 3.2

Omnia ST 3.2 is Ferroli’s split air-to-water heat pump with a hot water cylinder built into the indoor unit. It uses R32 and is available from 4.2 to 15.9 kW.

The cylinder holds 190 litres on sizes 4 to 10 and 240 litres on 12 to 16T. The indoor unit can be extended with an 18-litre buffer tank, a solar thermal kit for the cylinder or a kit for two heating circuits with direct and mixed flow.

The heat pump works down to −25 °C outdoors and delivers water up to 65 °C. At A7/W35, COP reaches up to 5.15, and low-temperature SCOP is up to 5.21. The energy class for domestic hot water is A+.

The outdoor unit is the same type as in Omnia S 3.2, and the indoor unit has a sound power of 42 to 43 dB(A). The refrigerant pipes can be up to 30 metres long.

Connection to the electrical supply and heating system is carried out by an authorised electrician and plumber. We will find a certified installer in your region.
