Two sources, at once.
The double coil combines solar collectors with a heat pump or boiler in one body. Energy costs drop, the carbon footprint shrinks.
Maintenance in minutes.
The coil placed in the bottom dished end removes as a single piece. In case of scaling, only the coil is replaced — not the unit.
No room for Legionella.
Strategic coil placement heats water from the lowest point. Homogeneous heat distribution removes the cold zones where bacteria grow.
An anode that sacrifices itself.
The magnesium anode rod corrodes instead of the tank. Simple to inspect, simple to replace.
Armour against corrosion.
Fen-X Plus Defender inner coating plus high-density polyurethane insulation: water stays hot far longer.
3 standard heaters.
1 FENNEX.



25% more capacity, 25% energy savings with a wider heating surface.
Wider surface, less energy.
From a single villa to a hospital campus.
Superior corrosion resistance, drinking-water grade hygiene.
Replace the part, not the unit.
