Ariston has steadily built up a strong reputation for performance and reliability. It offers affordable, budget-friendly models but also has a couple of premium range boilers, the Alteas ONE and Genus ONE, are able to go toe-to-toe with premium models from the likes of Worcester Bosch and Viessmann. They both have an energy efficiency rating of 94% and come with a fantastic 12 year warranty as standard.

Ariston combi boilers

Combi boilers are compact, condensing units that connect directly to your mains water supply. This has two major benefits. The first is that you don’t have to wait for hot water; simply turn on the tap and your combi boiler will fire up and produce hot water. The second is that you don’t have to install a hot water cylinder or cold water storage tank, which frees up space in your home and saves you money.

Ariston manufactures four models of combi boilers, ranging in size from 22kW to 31kW. This smaller size will be suitable for smaller homes with up to 9 radiators, whilst a 31kW boiler will be more suited to 3-4 bedroom houses with up to 15 radiators.

Ariston system boilers

System boilers connect to the mains water but also require a hot water cylinder to store water. The advantage of this is that unlike a combi boiler, a system boiler is able to supply hot water to multiple outlets at the same time. If you have a house with a high demand for hot water or more than one bathroom, a system boiler will be able to meet your needs.

The system boilers from Ariston vary in output size from 18kW and 30kW, making them a good choice for small and medium-large houses. All of Ariston’s system boilers are A-rated for efficiency and work with a range of wired and wireless controls.
