Ariston Clas System ONE System Boiler Pros and Cons
After extensively reviewing the Ariston Clas System ONE system boiler, we've identified several compelling advantages alongside a few notable drawbacks you'll want to contemplate.
On the plus side, you'll get exceptional energy efficiency with its A-rated ErP rating and XtraTech stainless steel heat exchanger. The super silent operation means you won't be disturbed by noisy heating, while the 8-year warranty provides valuable peace of mind.
However, there are some considerations to keep in mind:
- You'll need to invest more upfront compared to competing models.

The Ariston's price point of £990-£1,122 makes it a more budget-friendly option than the premium Worcester Bosch Greenstar 8000 Style.
While it may not have fancy wireless features like the Worcester, it does offer user-friendly controls that outshine the basic interface of the Viessmann.
