OPALIA EXTERNAL 
The Opalia External F range of gas water heaters is easy to install outdoors and control from indoors via a remote control with a 10-meter cable included. The Opalia F model is available in 12- and 15-liter sealed-chamber versions, all with electronic ignition, and available in natural gas and LPG models.
A new burner allows NOx emissions to be reduced to a minimum and achieved Class 6, as required by the ErP directive.
Modern design and extremely compact dimensions (18cm deep)
The water heaters can be easily installed outdoors as they are IPX5D certified and come with frost protection down to -25°C.
Very simple to install
They do not require connections to the flue as they have a facade exhaust already integrated into the front panel (Type A approval).
Maximum Security
The safety thermostat intervenes in the event of overheating of the domestic hot water; the ionization flame control blocks the gas supply in the event of a burner flame failure.
Electronic Control
It is possible to optimally adapt the operation of the appliance to the conditions of use and the hot water temperature, ensuring maximum sanitary comfort and optimizing gas consumption.
