CLAS ONE combi

Ariston’s CLAS ONE gas condensing combi range uses its XtraTech stainless-steel heat exchanger. The combi arrangement provides heating and domestic hot water without a separate hot-water cylinder. Suitability still depends on your property and water supply.

System and regular arrangements

Ariston also publishes CLAS ONE system and regular boiler ranges. These serve different system layouts. We check your existing cylinder, pumps and controls before recommending a change of boiler type.

Compare the package, not just the name

Your quote should identify the exact model and output, the controls included and any installation extras. If you are comparing CLAS, E-Combi or another Ariston model, ask us to set out the differences for your particular home.

Keep the product name and warranty offer together. A manufacturer’s general product page does not establish the warranty attached to every installer package. We confirm the applicable cover, registration and servicing requirements with your written quotation.

From enquiry to installation

1. Tell us about your home

Share your postcode, existing boiler type and what you want to improve. Photos can help us understand the starting point.

2. Agree the survey route

We confirm the suitable survey arrangements and assess the installation. An enquiry is not a confirmed appointment.

3. Review your written quote

Compare the exact model, installation scope, controls and warranty terms. Any additional work should be clear before acceptance.

4. Plan installation and aftercare

Once the work is agreed, the office confirms arrangements. Keep the handover information and follow the applicable servicing requirements.

Questions worth asking

Are all Ariston boilers the same inside?

No. Features, outputs, controls and warranty arrangements vary by range and model. The XtraTech statement here relates to the CLAS ONE range; we check the specification of the model actually being quoted.

What warranty will my quotation include?

We confirm the cover for your exact model and package in writing. Registration, installation conditions and ongoing servicing requirements must be checked; there is no single warranty promise for every model on this page.

Can I ask about finance?

Yes. Ask the team for the current available options and full terms alongside your quotation. Finance availability is subject to the relevant eligibility and affordability checks.

Care for the whole heating system

Explore MagnaCleanse and system protection and make a boiler servicing enquiry. Cleaning and maintenance should be appropriate to the equipment and condition of the system.
