Assess heat transfer at corners with measurements

Corner behaviour depends on wall construction, joints and seals. Assess surface observations separately from product-zone readings.

Short answer

Corners can form thermal bridges in some designs; do not assume the same result for every carrier. Inspect inner and outer surfaces, lid joints and corner damage. Place the product-zone sensor where it represents the load and compare readings under matched load and operating conditions.

Heat transfer depends on wall layers, connections and joint design. A corner's surface feel or condensation alone does not show product temperature.

Inspect the construction

Look for insulation breaks or damage at corners, lid frames, hinges and metal fittings. Verify the model section and maintenance instructions in manufacturer documentation.

Separate surface and load readings

Record surface temperature with a separate contact measurement. Place the product-zone logger where it represents the load and note its position.

Compare under matched conditions

Compare loads near a corner and in the centre only with the same product, starting condition and route. One trial does not establish a design-wide rule.
