Case study (anonymised, live data)

ASHP survey case study: detached house with wet UFH

A real North Yorkshire survey where room-level UFH detail mattered before design started.

This page uses live Vertex survey data and real survey photos with personal details removed. No customer name, address, or identifying location data is shown.

What was captured on this survey

This page shows the parts of the survey that mattered most to the installer: room count, UFH rooms, electrics, cylinder, and floor-plan evidence.

Wet UFH rooms

Entrance Hall, Living Room, Utility Room, Kitchen, Dining Room, Lounge, and WC.

Ready to use

Room-by-room data, floor plans, electrical evidence, and service photos were all kept in one report.

Real survey photos used in the case study. Identifying details were removed before publication.

How this helps before design and quotation

Emitter strategy

Seven rooms were already flagged as wet UFH, while radiator entries remained visible in other spaces. That avoids assumptions when planning mixed emitter layouts.

Electrical confidence

Supply phase, fuse rating, spare ways, and clear CU/cutout photos were captured in one pass, reducing avoidable return visits for electrical clarification.

Moves faster

The report combined floor plans, room records, and photo evidence in a single structure, helping the people pricing, designing, and fitting the job work from the same survey narrative.

Scope boundary

Final heat loss calculation method, system sizing, and detailed design decisions remain with the installer unless separately commissioned.
