Choose what you want to understand next
Start with suitability if you are still deciding whether a heat pump fits the property. Move into sizing, radiators, cylinders and siting when comparing technical proposals. Use the cost, funding and heating-comparison guides when weighing the financial decision.
- Suitability guides identify the questions a property assessment must answer.
- Design guides explain the assumptions that should appear in a useful proposal.
- Living-with-a-heat-pump guides cover winter operation, schedules and controls.
- Care guides separate safe homeowner checks from work for a qualified engineer.
Where rules, funding or product instructions can change, the guide links to an independent source and makes clear which decisions still need a property-specific survey.
