Ariston E-Combi ONE 24 LPG Key Specifications

Technical values above are based on Ariston’s current E-Combi ONE LPG 24 technical data.

XtraTech Stainless Steel Heat Exchanger

The E-Combi ONE LPG uses Ariston’s XtraTech stainless steel heat exchanger. Ariston describes the XtraTech design as having wider waterways designed to improve water flow and heating performance.

For buyers searching for an Ariston LPG combi boiler with stainless steel heat exchanger, this is one of the key product features to consider.

Horizontal Flue Kit

This package includes a horizontal flue kit for installations where the boiler’s flue route is designed to terminate horizontally.

The flue arrangement must be installed using compatible Ariston components and according to the manufacturer’s installation instructions. Flue length, terminal position, clearances, bends and termination requirements must be checked for the actual installation.

Do not assume that every horizontal flue arrangement is permitted at every property. Installation must comply with the applicable gas, building, ventilation and flue regulations in the country where the appliance is installed.

A-Rated LPG Condensing Boiler

The Ariston E-Combi ONE LPG 24 has an A/A ErP rating for heating and domestic hot water. Ariston lists a 93% seasonal space-heating efficiency and 85% water-heating energy efficiency for the LPG 24 model.

The boiler also includes Ariston’s Auto function, which adjusts boiler operation according to heating-system temperature requirements.

Domestic Hot Water Performance

The E-Combi ONE 24 LPG is designed to provide domestic hot water directly through the combi boiler without requiring a separate conventional hot-water storage cylinder for normal combi operation.

The LPG 24 model has a published 10.6 L/min DHW flow rate at a 35°C temperature rise and a maximum DHW heat output of 26 kW.

Actual hot-water performance depends on incoming water temperature, mains pressure, flow demand, pipework and installation conditions.

Compact Combi Boiler Design

The appliance includes:

• Backlit user display
• Auto function
• Comfort function
• High-efficiency pump
• XtraTech stainless steel heat exchanger
• Electronic controls
• Integrated expansion vessel
• Condensing technology
• Ariston control compatibility

• LPG-heated homes
• Properties without mains natural gas
• Holiday homes
• Park homes and leisure accommodation
• Residential heating upgrades
• LPG boiler replacement projects
• Properties requiring central heating and domestic hot water from one appliance
• Installations requiring a horizontal flue configuration

The suitability of the boiler should always be confirmed against the property’s heating load, hot-water demand, LPG supply and proposed flue arrangement.
