Compare space, groundworks, seasonal behaviour, budget and maintenance before choosing. Begin by writing down what you already know and what still needs to be measured. For this topic, use “Where the heat comes from” as the first evidence check and “Practical trade-offs” as the point where assumptions should be made visible.
Ask what information would confirm or overturn the recommendation. That might be a room heat-loss figure, emitter output, controller history, fault code, annual energy record, roof or ground constraint, acoustic calculation, current scheme rule or manufacturer instruction. The relevant evidence depends on air source vs ground source heat pumps, so it should be named rather than hidden behind a general assurance.
Record alternatives as well as the preferred route. If the answer changes with a lower flow temperature, different emitter, revised cylinder size, alternative outdoor position, fabric improvement or different maintenance finding, keep that option beside the associated cost and disruption. It makes later comparisons more useful and reduces the risk of selecting equipment before the scope is understood.
Prepare the next conversationQuestions for air source heat pumps
Use “Choose from the property outward” to decide what needs to appear in the written proposal or visit record. The document should separate confirmed findings, homeowner choices, installer responsibilities, third-party work and items that remain provisional until the site is opened up or further testing is completed.
Bring the property type, current fuel, recent energy use where available, rooms that behave differently, hot-water pattern and planned building work. For an existing system, add the make, model, settings, service history and when any symptom occurs. For a new project, add the comfort outcome, acceptable disruption and the space available for equipment.
Finally, keep the calculation, proposal, commissioning results, settings, warranties and service record together. Those documents turn air source vs ground source heat pumps from a one-off decision into useful evidence for handover, adjustment, maintenance and future fault finding.
