- Affordable: Ariston boilers are conveniently priced at a range of £600–£1,400, with an average cost of £963 depending on the boiler type, model, and output capacity you choose. This pits Ariston as one of the most affordable boiler manufacturers available in the UK today.

Like any boiler model, Ariston boilers come with some drawbacks worth considering when making your decision. Here are some of the key points to look out for:
- Average efficiency: Ariston boilers come with an A+ energy efficiency standard, but do not always live up to the higher energy efficiency classes of some manufacturers. For example, manufacturers like LG and Worcester Bosch also have boilers that boast an A+++ efficiency rating in comparison.
- Cheaper components: While very affordable, Ariston boilers use cheaper components than their premium counterparts. This can make repairs and replacements cheaper, but in turn increases the risk of dysfunction, such as leaks and expanding vessels.
- Shorter lifespan: On account of the cheaper components used in Ariston boilers, they are more likely to need service every 5 years or so, as opposed to the 15+ year functionality of more premium brands like Worcester Bosch.
- Louder boilers: Ariston boilers tend to be a lot noisier than their counterparts. For example, the Viessmann Vitodens 200 keeps noise down to an impressive 36 db in comparison to the more average 49 - 52 db of most Ariston boilers.
To make the best decision, consulting with a professional heating engineer is your best bet. That way, they can tailor the best course of action for your needs.
