Ariston FAST R ONM 11 NG UA Gas Water Heater is a simple and productive flue-type model that runs on gas.

Model Advantages

Ariston FAST R ONM 11 NG UA has high efficiency, is inexpensive, easy to operate, and reliable. It is distinguished by:

1) High level of safety: protected from breakdown in case of low water pressure. Overheat protection is provided. If the gas goes out, the gas supply will immediately stop.

2) Excellent operational efficiency: achieved by quickly heating a large volume of water - 11 l/min.

3) Simple control: mechanical, located on the front panel.

Technical Features of Ariston FAST R ONM 11 NG UA

The model takes up relatively little space: 31x58x21 cm, weighs only 8.9 kg, so there are no difficulties with placing the appliance.

In addition, Fast Evo Ont B 11 NG heats water very quietly.

The combustion chamber is open. Inside there is a copper heat exchanger.

To start the system, electronic ignition (battery-powered) is used – this is convenient and safe.
