Methodology
How the ar heat pump visualiser works
Uses the phone’s camera to place a full-size heat pump or hot water cylinder in the visitor’s own space.
How it works
KarbonKit’s models match the outside dimensions of real products of each size, without their branding. They are fixed at full size, so pinching doesn’t resize them.
The phone finds the floor and places the model on it (WebXR on Android, AR Quick Look on iPhone). Placement is more accurate in good light, on a floor with some texture.

Limits
- Real units vary, so check the data sheet for the one you are quoted. Units also need clear space around them for airflow and servicing, which the model doesn’t show.
- Branded models are shown at the size in their model file, which we haven’t checked against the product.
- It shows size and position only, not noise or whether the spot meets planning rules.
