Review: More than expectations - Unvented solves the pressure through taps Review: Perfect for Flats and small houses. - Purchased to replace Ariston ST100 which is no longer available unfortunately. Taller than original heater so had to alter existing pipework and resize connector to undersize of heater. Why Ariston changed the layout and sizes baffles me except if it was to bring in line with European heaters. Fitted heater in 3 hours and now working as expected. Heater elements are always suspect on these heaters as they corrode away. ## Features - Water heater designed and manufactured to be installed in UK. - “Eco Evo” Function: The innovative ECO EVO function memorises user habits to deliver hot water while saving up to 14% on energy bills. The product operates in compliance with top standards on energy efficiency within the electric water heating category. - WaterPlus patented technology: Ariston's groundbreaking WaterPlus technology keeps the incoming cold water at the bottom of the tank, reducing the mix with stored hot water, for up to 16% more hot water availability. - TitanShield technology for tank protection: The inner surface of the tank is enamelled with a layer of titanium, an anti-corrosion and rust-resistant material, which prevents the surface from corroding, even when in contact with warm water. Titanium’s natural properties are boosted by the action of a large magnesium anode that stops the oxidation reactions on the tank’s inner surface, prolonging the life of the water heater. - Total Safety: Pro 1 water heaters have passed all safety tests necessary to meet the standards required by EC directives. The ABS safety package offers protection for both the product and its users. Furthermore, the included Anti Legionella system performs a complete cycle of heating to a temperature of 65° C to sanitize and remove any bacteria present in the accumulated water. - Suitable to any space: Pro1, with a width of only 35,3 cm, has been designed to fit any space. The innovative installation kit allows the replacement of the boiler (of the same dimensions) without having to drill the wall again. - Ideal Installations: 1-2 Bedroom Properties Small Hospitality & Retail Units Cylinder Replacement Installations - Fully UKCA certified to be installed in the UK Market. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08HDX2JGH | | Best Sellers Rank | 101,232 in DIY & Tools ( See Top 100 in DIY & Tools ) 164 in Water Heaters & Parts | | Brand | Ariston | | Capacity | 80 litres | | Colour | White | | Country of Origin | Italy | | Customer Reviews | 4.7 4.7 out of 5 stars (37) | | Efficiency | B | | Included Components | 12L expansion vessel, combination valve, discharge tundish, instruction manual, warranty certificate | | Is Electric | Yes | | Item Dimensions W x H | 48W x 81H centimetres | | Item Type Name | PRO1 ECO 80L UK incl. unvented kit | | Item Weight | 29.6 Kilograms | | Manufacturer | Ariston | | Manufacturer Warranty Description | 3. | | Material | Titanium finished steel | | Maximum Temperature | 65 Degrees Celsius | | Model Number | 3820020 | | Mount Type | Wall | | Part Number | 3820020 | | Power source | Corded Electric | | Special Features | Eco Evo Function, WaterPlus Technology, TitanShield Technology | | Style | Protection | | Unit Count | 1.0 count | | Voltage | 240 Volts | ## Product Details - **Brand:** Ariston - **Capacity:** 80 litres - **Power source:** Corded Electric - **Product dimensions:** 48W x 81H centimetres - **Special feature:** Eco Evo Function, WaterPlus Technology, TitanShield Technology ## Images ![Ariston PRO1 ECO 80 L Electric Storage Water Heater, Inclusive Of Unvented Kit, B Class Erp Rating, Waterplus Technology, Titanshield Technology, Manufactured To Be Installed In UK - 3820020. , White - Image 1](https://m.media-amazon.com/images/I/610pF3xIbBL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Can this heater be installed up in a loft** A: Good Morning, Thank you for your questions.
