Elco AEROTOP SX

AEROTOP SX is a monobloc air-to-water heat pump for outdoor installation. It heats, cools and produces hot water and, according to Elco, is one of the quietest air-to-water heat pumps in Germany.

SX7 has a sound power of 50 dB(A), and at a distance of 3 metres the sound pressure is 33 dB(A). Elco specifies a distance to the property boundary of just 3 metres for SX7 and 5 metres for SX10 and SX13.

The heat pump delivers flow temperatures up to 60 °C at an outdoor temperature of -10 °C and keeps running down to -20 °C. Active cooling is always built in, and the refrigerant is R32.

The outdoor unit runs on 400 V. Two identical units can be connected in cascade for 14, 20 or 25 kW.

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.
