Inside the Eneeergy technology

The Eneeergy hybrid tank uses duplex 2205 stainless steel and dual heating: solar PV as the main source and electric backup only when needed. Efficient, long-lasting and maintenance-free.

How the dual system works

Eneeergy uses a dual-storage layout: lower tank heated by solar PV and upper tank for backup only when required.

01
Solar priority
Solar PV heats the base tank every day — renewable hot water guaranteed.
02
Smart backup
Electric backup activates automatically only when needed.
03
Self-regulation
The controller manages both heaters, always prioritising solar.
Typical homes achieve 70–90% renewable coverage depending on climate, dwelling and usage profile.

Technical summary

Technical summary in three points

The Eneeergy system is designed to combine maximum use of solar PV with stable comfort and very simple installation for the installer.

Solar

Automatic solar priority

The electronic controller decides where the heat comes from at every moment and always prioritises solar energy before using the electric heater, reducing grid consumption.

Tank

Stratified storage tank

The internal design keeps a hot water reserve at the top of the tank, reducing start-ups and avoiding noticeable temperature swings at the taps even during peak demand.

Installation

Plug & play installation

Clear connections, integrated electronics and high-quality insulation: the unit fits most homes without major building works or bathroom refurbishments.
