ARISTON PRO1 ECO 100 H 100 l 1.8 kW electric water heater, horizontal, 3201423

ARISTON PRO1 ECO 100 H, product code 3201423, is a horizontal wall-mounted electric storage water heater in the 100 L capacity category with a rated power of 1.8 kW. It combines electronic temperature control, the intelligent ECO EVO function, WaterPlus technology, SHOWER READY indication and ARISTON tank-protection solutions. For the specific 100 H 1.8K EN EU version, ARISTON specifies horizontal installation, 230 V supply, energy efficiency class B and load profile M.
ECO EVO, powered by CoreTech technology, learns the user's hot-water consumption habits, automatically creates an operating programme and adapts water temperature throughout the day according to actual demand. ARISTON specifies energy savings of up to 14%. An electronic thermostat provides precise temperature adjustment, while the digital control panel makes operation clear and convenient.
WaterPlus technology keeps incoming cold water in the lower part of the tank and reduces mixing with the already heated water. This provides access to up to 16% more available hot water. The SHOWER READY indicator shows when enough hot water has been prepared for a shower.
PRO1 ECO H also includes an Anti-Legionella thermal disinfection function. Once per month, a dedicated programme automatically raises the water temperature to 65 °C, helping limit the development of Legionella bacteria. The electronic thermostat also incorporates emergency protection and anti-freeze functionality.
The inner storage tank is coated with high-quality titanium enamel, while a magnesium anode provides additional corrosion protection and helps extend tank life. High-quality polyurethane insulation reduces heat loss. The model also features a white outer casing, digital display and user-friendly High-Tech control interface.
For the specific PRO1 ECO 100 H 1.8K EN EU, 3201423, rated power is 1.8 kW, supply voltage 230 V, maximum operating temperature 80 °C, maximum working pressure 8 bar and protection rating IPX1. Heating time at ΔT = 45 °C is 2 h 46 min, standing heat loss at 65 °C is 1.65 kWh/24 h, and weight is 24 kg.
