The Energy Saving Tech Force (EOT-EXE), in collaboration with ANDRIANOS, recently completed an important energy upgrade project in an existing residence in Glykorizi, Messinia.
With specialized expertise and top-quality equipment, the ANDRIANOS team designed and implemented a comprehensive energy system, ensuring maximum efficiency and a significant reduction in annual operating costs.
After 20 years since the successful installation of a central heating system with an oil boiler, the client trusted us once again for the new energy upgrade of their home.
The replacement of old energy-consuming systems with new, innovative solutions for heating, cooling, and domestic hot water contributed to improved comfort and reduced environmental footprint. Below are the interventions carried out:
Heating with Heat Pump
Installation of an Ariston Nimbus Pocket A+++ Inverter heat pump (monoblock), which was connected to the existing radiators, offering efficient and economical heating. With eco-friendly R32 refrigerant and power up to 11.74 kW, it ensures high performance with low operating cost. Learn more.
The ARISTON NIMBUS POCKET 80MNET R32 heat pump installed outside the house, with a magnetic filter and corrosion inhibitor for network protection.
The residence had an old oil boiler for space heating, which will now be used as a backup option, as the heat pump offers significantly greater savings. Additionally, a 60L buffer tank, WILO Yonos Pico circulator, and an 8L REFLEX Germany expansion vessel were installed in the boiler room.

Temperature Control with Modern Thermostats
Replacement of the old thermostat with the modern wired wall-mounted ENGO Controls EASY230W thermostat for precise and easy temperature regulation.
The Engo Controls thermostat installed in the optimal location according to residents’ needs and preferences
Cooling with High Energy Efficiency Air Conditioners
Installation of two Carrier Superia air conditioners with energy class A++ in cooling mode, ensuring comfort and energy savings during the summer months. They feature advanced functions such as dehumidification, draft prevention, triple-action air purification system, and remote control capability via the free “Carrier Air Conditioner” app, making them unique in their category.
The indoor and outdoor unit of the Carrier Superia 24,000 BTU
The indoor and outdoor unit of the Carrier Superia 9,000 BTU
Domestic Hot Water Production with Hybrid Solar Water Heater
Installation of an Ariston Lydos Hybrid 100 electric hybrid water heater, energy class A, which effectively combines electrical energy with renewable energy from the heat pump and adapts to user habits for optimal performance.
