The Ariston forced circulation gas instant water heater can provide the best performance thanks to the highest quality standard that ensures over 90% efficiency.

The external installation combined with the forced flow of the product's exhaust gases guarantees maximum safety. The forced flow device for internal installation eliminates any possibility of gas leakage inside the house, thanks to the fan that ensures the evacuation of the chimney's exhaust gases.

Thanks to the NTC sensor, the water heater will adjust the burner according to the water flow variation to ensure a stable temperature, maximizing comfort.

Easy to use with a large screen, clear information.

It can be connected to a system with Ariston solar products.

It is central and can be used either as the main option for heating the water for household use, or as a supplementary. It can provide hot water throughout the house for your everyday needs, as long as there are suitable pipes for distributing the hot water. This may potentially result in heat and energy losses due to distance.

The instant water heater is a type of heater that heats water in real time

It only heats the water that passes through it at that moment. There is no storage tank for hot water. This has many advantages, such as energy saving, as only the water that is used is heated, as well as longer lifespan, as there is no water tank and accumulation of salts in the heating element and other components.

It operates with liquefied gas (gas), and no electrical installation is required.

The instant water heater has a cold water inlet pipe, which passes through the heating element, heats up, and comes out in the hot water outlet pipe. A necessary condition for the initial operation of the instant water heater is that the pressure of the cold water inlet is not too low.

The temperature of the water is regulated by a thermostat, so that it does not exceed a maximum value. The temperatures reached by the hot water are pre-set so that someone can use the hot water directly, without the need to mix it with cold water.

The maximum temperature that can be reached for hot water production is 65 °C, while the maximum flow rate of water reaches up to 16 liters per minute. As an indication, 38-42 °C degrees are the standard for shower use.

• It is small in size and does not take up much space.
• There is no energy loss, as only the water that is being used is heated at that moment. Therefore, there is savings on the electricity bill. In a traditional water heater, the unused hot water goes to waste.
• The hot water used in the instant water heater is used as is, without mixing with cold water, as in a traditional water heater. This also saves water, in addition to electricity.
• There is no need to wait for the water to heat up. As soon as we turn on the tap, hot water starts running in a few seconds. A traditional water heater takes some minutes, depending on its size.
• The hot water never runs out. As long as we have the tap open, we will have hot water.
