No engineering knowledge needed. Assess First. Recommend Second.
How our Boiler Finder works
Tell us about your fuel, existing system and hot-water routines. We suggest an arrangement to discuss and show matching configurations from Worcester Bosch, Baxi, Ideal Heating, Vaillant, Viessmann and Navien. You can revise answers and explore every matching option.
How boiler sizing works
You don’t need to know kilowatts or water-flow measurements. If you happen to know your current boiler’s output, you can add it as an optional detail. SwiftHeat calculates what your home needs during assessment.
Assess First. Recommend Second.
Guidance now. Assessment before specification.
The final boiler type, output and installation recommendation depend on your property and system assessment. The Finder does not size a boiler, set a price or confirm a warranty.

Boiler Finder questions
How does the Boiler Finder work?
It asks about your home, existing heating and hot-water routines, then offers an advisory starting point and relevant guides. It does not confirm appliance suitability.
Will it tell me exactly what size boiler I need?
No. Bedrooms and bathrooms provide context, not a sizing formula. SwiftHeat confirms the specification through a professional assessment, including heat loss and hot-water requirements.
Do I still need a boiler assessment?
Yes. The water supply, fuel, system condition, flue, controls and installation requirements must be checked before a final recommendation and quotation.
Can I explore different manufacturers?
Yes. You can choose a preference or leave it open. Where the approved catalogue supports a relevant arrangement, the result links to existing range guides for further research.
Does the number of bathrooms affect which boiler I need?
The number of bathrooms provides context, but simultaneous use and measured supply matter more than the count alone. We assess stored-water capacity or combi performance against your household routines.
Can I get a quotation after using the Finder?
Yes. The quotation button opens our existing enquiry form. Where your browser permits, your Finder summary is included in the editable message so the team can discuss your requirements.
