De Dietrich Alezio M Compact R290
The De Dietrich Alezio M Compact R290 is a reversible monobloc air-to-water heat pump with propane as refrigerant and an indoor unit with a built-in 180 l hot water cylinder. It is designed to replace an existing water heater.
Output ranges from 4.4 to 13.5 kW with a COP of up to 5.17 for space heating, and the flow can reach 75 °C. The cylinder is made of enamelled steel and provides 249 l of domestic hot water at 40 °C. The hot water COP is between 2.48 and 2.58.
The indoor unit combines E-Pilot control, an 8 l expansion vessel, an automatic air vent, a safety valve, an electronic pressure sensor, a flow meter, a magnetic filter and a 6 kW staged immersion heater. The outdoor unit is grey and compact, with a built-in circulation pump, expansion vessel and inverter compressor.
The heat pump can be used for radiators, underfloor heating and underfloor cooling. Up to two circuits can be controlled, with an optional extra buffer, and the controller connects to the SMART TC° room sensor and the De Dietrich SMART app.
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.
