The Ariston Pro1 R 100V 1.8K PL vertical water heater combines high heating power, an increased useful volume of hot water, and signature Italian reliability. Its 100-liter capacity is ideal for families of 3–4 people or facilities with a high demand for domestic hot water.
WaterPlus — more hot water with the same tank volume
Thanks to the WaterPlus technology, cold water does not mix with hot water and remains in the lower part of the tank. This increases heating efficiency and provides up to 16% more available hot water—especially beneficial for vertical models.
