Brand

Ariston

Ariston is a leading brand in the heating and hot water industry, with a reputation for quality, efficiency, and innovation. Ariston is part of the Ariston Thermo Group, an Italian corporation that is a global leader in thermal comfort. As of my knowledge cutoff in September 2021, Ariston offers a range of boilers to suit a variety of needs, including:

Combi Boilers: Ariston's combi boilers are efficient and space-saving, as they combine central heating and hot water supply in one compact unit. They provide hot water on demand directly from the mains, eliminating the need for a hot water storage tank.
System Boilers: Ariston's system boilers are designed to supply your home with central heating and hot water by using a separate cylinder for water storage. They are ideal for homes with multiple bathrooms.
Regular Boilers: Also known as conventional or traditional boilers, these boilers are suitable for homes with an older radiator system or for properties where a lot of hot water is used at the same time.

Ariston boilers are known for their advanced features, including user-friendly controls and high efficiency ratings. Many of their boilers are also compatible with smart thermostats, giving you greater control over your home's heating and potential energy savings. In terms of customer support, Ariston offers warranties on their boilers and has a network of service engineers for installation and maintenance. They also provide online resources and technical support for customers.
