Quick answer: send the heater, label and connections
The most useful set is one wide photo of the full heater and surrounding space, one readable photo of the manufacturer/model label, and one photo of the vent path or top electrical and plumbing connections.
Photo 1: the full heater and surrounding space
This shows the physical size, access, nearby walls, floor conditions and many visible installation details. Stand back far enough to include the whole heater from floor to the piping or vent above it.
Photo 2: the manufacturer and model label
The rating label helps identify fuel type, capacity, model family and other equipment information. The small print needs to be readable, so move closer instead of relying on digital zoom.
Photo 3: the vent or top connections
For gas equipment, show the visible exhaust path and where it joins a chimney, wall route or shared vent. For electric or heat-pump equipment, show the top water lines and electrical connection instead.
What photos can and cannot confirm
Photos can eliminate a lot of unnecessary guessing, but they cannot prove every hidden condition. Chimney condition, concealed piping, electrical capacity, water pressure, permit requirements or other site-specific issues may still need verification before affected work is finalized.
Why the process can improve speed
When the equipment and visible scope are known before dispatch, the team can prepare the right replacement options, ask better questions and avoid treating every request like an unknown diagnostic call. Same-day completion still depends on equipment, crew, scope and local requirements.
