SPHERA EVO 2.0 Invisible is the ideal choice for all homes that do not have a technical room and which need to make the unit invisible by embedding it in the wall.
The cabinet has an adjustable telescopic frame and can be painted to make the unit disappear completely.

Edge EVO 2.0 - EXC Hybrid version is the solution designed for upgrading old generators without having to alter the system. The system is in fact extremely versatile and able to adapt to whatever already exists: it simply replaces the generator that produces Heating and Domestic Hot Water, improving comfort and efficiency, as well as ensuring peace of mind.

Edge F is the heat pump with R-290 refrigerant designed for the future, it is in fact a natural gas, and already in accordance with the current strict European regulations. The high thermodynamic qualities of this new refrigerant allow the production of water at unprecedented temperatures, 75 °C supply down to -10 °C ambient.
Respect for the environment and temperatures comparable to a boiler for a full-electric future.

SPHERA EVO 2.0 EASYHybrid Box has a function that can be selected directly from the interface, which makes it possible to calculate the resource (heat pump and/or boiler) that is able to fulfil the heat demand with the lowest economic cost in every operating condition. To use the €-Switch function, simply enter the cost per kWh of electricity and the cost per m³ of methane gas from the energy provider’s supply contract, and define the main type of terminals in the building (radiant panel, fan coil, radiator).

AQUA Plus transforms the renewable energy in the air into heat to be used to increase the temperature of the domestic hot water in the storage tank. This is done with minimal use of electricity, so much so that it boasts the market-leading A+ efficiency class.
The total heating capacity available (1.6 kW or 2.2 kW heat pump and 1.5 kW additional heater) means that hot water can always be produced in the best possible way.
Operation with renewable energy alone, which for even more virtuous operations can be enhanced by the contribution of ELFOSun3 solar collectors, is guaranteed in practically all climates: between -7 °C and 43 °C. In extreme conditions, the production of hot water continues in combination with the electric heater with the outdoor air down to -20 °C.

As well as renewing and purifying the ambient air, ELFOFresh EVO is a real support for the main heating and cooling generator.
Alone, it can fulfil up to 85% of the thermal demands of the house, whereas a traditional passive recuperator can typically only contribute between 10% (in summer) and 45% (in winter).
In spring or autumn, when the weather is mild, ELFOFresh EVO works mainly in Free Cooling / Heating: it only uses the thermal content of outdoor air for air conditioning, working at virtually zero (energy and economic) cost.
Chosen during design, ELFOFresh EVO allows a smaller generator to be used: less space and cheaper!
