DROPS M4.1 domestic hot water heat pump – Efficient hot water preparation

Device features

The DOMESTIC HOT WATERheat pump The DROPS M4.1 impresses with its highly efficient rotary compressor, which ensures reliable and economical heat recovery. An additional expansion valve guarantees effective and rapid evaporator defrosting, while the energy-efficient radial fan ensures optimal air circulation.

The evaporator with its hydrophilic surface is less prone to icing, defrosts effectively, and offers better protection against contamination. An integrated circulation pump with PZH certification guarantees hygienic and safe circulation of the domestic hot water. A plate heat exchanger is used for more direct water heating, and the lightweight, removable plastic housing effectively reduces the noise of the cooling system.

Basic functions

The DROPS M4.1 enables simple and quick indoor installation and is characterized by high energy efficiency. Pressure and temperature protection of the refrigeration system ensures maximum safety, while defrosting of the evaporator via hot gas occurs automatically by reversing the refrigeration cycle.

An automatic frost protection system for the water system prevents damage at sub-zero temperatures. The integrated weekly schedule allows you to set the desired water temperature for different times, and optional connection to a photovoltaic system is possible via a potential-free normally open contact.

The control unit regulates an external electric heater installed in the storage tank, as well as the domestic hot water circulation pump, according to a timer. All components that come into contact with domestic hot water are PZH-certified and meet the highest hygiene standards.

Installation and operation

The heat pump is operated via a manual control with a graphic display (M) or optionally with an intuitive color touchscreen (D). The user-friendly interface allows for quick adjustment of all operating parameters and a clear display of temperatures and time settings.

Thanks to adjustable feet, the DROPS M4.1 can be easily mounted on any flat surface. The removable plastic housing allows quick access to the components and also contributes to noise reduction, resulting in particularly quiet operation.

Technical data

The heat pump It has a diameter of 661 mm and a height of 585 mm with an air duct diameter of 250 mm. Connections are made with ¾" internal threads. The refrigerant R134a is used in a charge of 0.60 kg. Water or a water-glycol mixture up to 50% serves as the heat transfer fluid at a maximum water pressure of 6 bar.

The unit can operate in a temperature range of -7 °C to +43 °C, with a maximum domestic hot water temperature of 55 °C. It has a sound power level of 57 dB, a voltage of 1/N/PE ~220–240 V/50 Hz, and a COP of 3.0 (A15/W10-55) or 3.3 (A20/W10At -55°C, the DROPS M4.1 achieves energy class A+. Its nominal heat output is 1.5 kW, and its total weight is 45 kg.
