LPG gas water heaters heat domestic water using liquefied petroleum gas. This category covers water-heating appliances; choose against the exact LPG model, hot-water demand and proposed installation rather than a general gas-heater description.
Ariston Fast Evo X LPG range
Ariston Fast Evo X brings together the ONT 11 LPG and ONT 14 LPG variants identified by Ariston's Greek manufacturer page. The range page includes model codes and a comparison table with clearly attributed ratings. Flow figures apply at the stated temperature rise; they are not storage capacities or guaranteed simultaneous-outlet performance.
What matters when selecting an LPG water heater?
Send the outlets to be served, expected simultaneous use, incoming-water conditions where known, existing appliance label and photographs of the proposed location. Exact gas type, appliance documentation and the installation arrangement need to be checked together.
Fast Evo X is described as open-chamber equipment for indoor installation. A qualified gas professional must assess the location, ventilation, combustion air and flue requirements against the exact manufacturer instructions and applicable local requirements. A battery-powered control does not make the appliance an electric water heater: LPG provides its heat.
Price, supply and source information
Request exact-model advice, price and availability from Thomas Moudouros Ltd in Cyprus. Catalogue presence does not confirm stock, local approval, warranty or installation suitability. The Fast Evo X page identifies its Greek technical source and illustrative Italian manufacturer image, including the Italian market's out-of-production notice. Supply and appearance of the actual LPG model require confirmation.
For other domestic-hot-water arrangements, compare Electric Water Heaters and Solar Hot Water. These alternatives need their own exact-model assessment; no interchangeability or system compatibility is implied.
