Ariston Boilers and Water Heaters
Ariston is better known in the UK for unvented cylinders and water heaters than for boilers, though its combi range does appear in some homes.
Ariston is better known in the UK for unvented cylinders and water heaters than for boilers, though its combi range does appear in some homes. We work across both the boiler and hot water storage side of the brand.
How the range is built
Ariston's cylinders and water heaters are a bigger part of what we encounter than their boilers, and the two product lines have quite different service needs.
What we see go wrong
On boilers, PCB and ignition faults are typical; on cylinders and unvented water heaters, it's usually thermostat or immersion element failure.
Servicing and parts
Parts for Ariston hot water products are generally accessible; boiler-specific parts can take slightly longer depending on the model's age.

Questions we get asked
Do you service Ariston unvented cylinders?
Yes, our engineers are qualified for unvented hot water work and can carry out the required annual checks.
Why has my Ariston water heater stopped heating?
A failed immersion element or thermostat is the most common cause we find, both of which are straightforward to replace.
Are Ariston boilers common in the UK?
Less so than some brands, but we still see and service them, particularly alongside Ariston hot water cylinders.
