Heat-pump sizing and heat-demand assessment — Heat-pump installer — Professionals
Sizing leads fit designers able to collect and interpret building-specific evidence. Confirm the required design stage, data quality and responsibility for emitter assessment, and avoid presenting a preliminary estimate as a final installation specification.
Service scope
Professional assessment of building heating and hot-water requirements to inform heat-pump and associated-system selection. Sizing must state the building evidence, design conditions and emitter assumptions; a rough area-based estimate is not equivalent to a complete room or system design.
What is normally included
- Building and demand-data assessment
- Heat-pump sizing recommendations
- Documented assumptions and design limitations
What is not included
- Equipment selection from floor area alone
- Guaranteed performance from an unverified online estimate
Qualification checks
- Agree the assessment purpose
- Review building-data reliability
- Define design conditions
- Include relevant emitter and hot-water needs
- Record uncertainty and future changes
Quote guidance
Price the survey, calculations and report according to the required design depth. Identify whether room-level emitter recommendations, revisions and installer coordination are included, and separate design work from supplying the selected equipment.
Lead risks
- An incomplete floor plan can conceal important construction differences
- Customers may expect a final design from a brief remote consultation
