Smart Features

Features that make everyday life more comfortable, efficient, and safe.

Υψηλή θερμοκρασία προσαγωγής νερού

High water supply temperature

The maximum temperature of the water leaving the heat pump and intended for space heating or domestic hot water production is 65°C.

Βοηθητική ηλεκτρική αντίσταση

Auxiliary electrical resistance

3kW, with the option of being activated or deactivated by the user, offering complete control over the unit's operation.

Αντλία νερού

Water pump

With a lifting capacity of up to 9 meters, to ensure efficient operation of the system.

Morris feature

Tri Thermal

This is a complete air-water heat pump system designed for heating, cooling, and domestic hot water (DHW) production. For maximum flexibility and ideal adaptation to the needs of each home, it can be combined with a backup heating source, such as an electric water heater, a conventional gas boiler, or a solar system.

Morris feature

All DC Inverter

The dual rotor DC Inverter compressor features an innovative, highly reliable design, ensuring resistance to high currents and trouble-free operation even at high temperatures. It provides uninterrupted heating at very low outdoor temperatures, extremely low noise levels, and full support for installations with long piping.


The DC fan motor offers continuous, stepless speed control, contributing to lower consumption, higher energy efficiency, enhanced reliability, and even lower noise levels.

Morris feature

3-zone temperature control

Hydraulic system with the ability to create up to three independent control zones, allowing different temperatures to be set in each zone for absolute comfort and adaptation to the needs of the space.

Morris feature

Redesigned L-type external temperature exchanger

It features hydrophilic, anti-corrosive fins that enhance heat transfer by up to 6%, offering higher efficiency and longer unit life.


Pipes with internal threads offer up to 10% improved heat exchange efficiency, contributing to faster and more stable operation in all conditions.

Morris feature

Specially designed for low noise

Extremely low noise levels during the night, so you can enjoy a truly comfortable and uninterrupted sleep.


Single fan design significantly reduces noise — up to 6 dB(A) lower than comparable dual fan outdoor units.


Special silent mode for even quieter operation, with noise levels below 45 dB(A).

Additional Features

Smart details that improve everyday use and offer greater convenience and comfort.

Αντιπαγωτική προστασία

Anti-freeze protection

The smart water system protects the circuit during winter, preventing problems such as frost cracks and other potential malfunctions.

Λειτουργία διακοπών

Holiday mode

During your absence, the pump operates at a low temperature to maintain water circuit protection and system stability.

Αποστείρωση ζεστού νερού χρήσης (ΖΝΧ) στους 70οC

Sterilization of hot water at 70°C

The high-temperature sterilization function ensures 99.9% effectiveness in eliminating Legionella bacteria, offering maximum hygiene.

Έξυπνος έλεγχος

Smart control

It provides remote management via mobile phone or other Android or iOS device, for instant and easy control from anywhere.

5-year warranty for the entire device

High-quality construction and carefully selected components ensure the long-term, reliable operation of MORRIS devices, reflecting the company's commitment to quality and safety in every application.
