ECO-THERMAL MONOBLOCK
The HTW Eco-thermal Monoblock is an aerothermal air conditioning system that offers exceptional efficiency and unmatched comfort.
With state-of-the-art technology, this heat pump is capable of harnessing 75% of the energy of the outside air to provide you with heating in winter and cooling in summer, as well as DHW.
Its efficient operation will allow you to save on electricity consumption, meaning significant economic savings on your electricity bill.
Among its main features we find:
- Impulsion at 65ºC without the use of electric resistance: The Eco-thermal Monoblock is able to impulse water at a temperature of 65ºC without the use of electric resistance support.
- It includes an electric resistance as standard. This gives you the option to use it in situations where an extra boost of heat is required, providing a higher level of comfort and for the anti legionella function.
- It uses Full Inverter DC technology, which means it optimizes performance and energy efficiency.
- It has anintegrated hydraulic unit, which simplifies installation and allows for optimal operation.
- The system has a wide operating range, so it can adapt to different environmental conditions: Cooling from -5°C to 43°C. Heating from -25°C to 43°C. Domestic Hot Water from -25°C to 43°C.
- Wifi Included with all functionalities controllable from a dedicated mobile app, so you can control and adjust the functions remotely. From anywhere and at any time, you can program the desired temperature and enjoy a comfortable environment when you return home.
- Intelligentdefrosting system that avoids continuous compressor starts and stops.
- Programmable vacation mode to protect the system from freezing pipes.
- It is environmentally friendly. By using air as a renewable energy source, it contributes to the reduction of CO2 emissions, helping to preserve our planet.
Available Powers: 4KW, 6KW, 8KW, 10KW, 12KW, 14KW, 16KW
