Atherton FAQs — combi boiler swap
What warranty comes with a combi swap?+
Depending on brand and range, typically 7–10 years fully parts-and-labour, registered on the day.
Can I choose the boiler brand?+
Yes. We stock Worcester, Vaillant, Ideal and Baxi and give the pros/cons of each at quote.
Do I need to upsize the pipework?+
Sometimes. Most 90s / early 2000s installs used 15mm gas pipe from the meter, and modern combis usually need 22mm — we check on the day.
What size combi do I need?+
One bathroom, up to 3 bedrooms: 28–30kW. Two bathrooms or a big kitchen tap load: 32–35kW.
Can I keep my existing radiators?+
Usually yes. We add a magnetic filter and dose the system with inhibitor so the new boiler isn't inheriting old system sludge.
