Rotenso Heatmi HES140X13i R14 Heat Pump Split 14kW 3PH Indoor unit

Rotenso Heatmi Split heat pump HES140X13i R14 3F (indoor unit)

The Rotenso Heatmi Split 14 kW heat pump consists of:

• indoor unit: hydraulic module with the HES140X13i symbol
• outdoor unit with the HES140X3o symbol (to be purchased separately).

This is a three-phase pump with a heating capacity of 14.50 kW (A7/W35) and high energy efficiency class A++ (for 35° flow temperature) and A++ (for 55° flow temperature). The COP for A7/W35 is as high as 4.75.

It provides high heating capacity down to an outdoor temperature of -25°C.

The maximum available water temperature in heating mode is: 65°C and in DHW mode it is: 60°C.

The pump has a 2-rotation inverter compressor. Refrigerant - R32.

In order to ensure trouble-free operation at temperatures below 0°C, the pump is equipped with a drip tray heater to prevent the condensate from freezing and the external unit from frosting, thus preventing possible damage to the fan and heat pump exchanger.

The second important piece of equipment is the compressor crankcase heater which, at temperatures below 0°C, heats the compressor oil and prepares the unit for trouble-free start-up in adverse weather conditions.

This technical solution guarantees trouble-free operation and extends the service life of the compressor - the heart of the heat pump.

The Heatmi Split 14 kW heat pump is equipped with a 9 kW modulating booster heater (3 kW +3 kW + 3 kW).

In emergency situations or at temperatures below the bivalent point, it is advisable for the pump to make use of the booster heaters when preparing hot water for central heating or DHW.

It is worth knowing that the use of heaters has a beneficial effect on the durability and reliability of the heat pump.

The Rotenso Heatmi pump can be controlled from a mobile application (Tuya Smart) as well as a modern wired controller with a menu in Polish, which has a built-in room temperature sensor and a Wi-Fi module.
