| The boiler's metal to water heat exchange surfaces become coated with oil and uneven heat transfer and a violent surging of boiler water may occur in extreme conditions. |
| In order to perform effectively as an insulant a material must restrict heat flow by any of the three methods of heat transfer. |
| Low emissivity glass has a special surface coating to reduce heat transfer back through the window. |
| Arctic and boreal mosses, for example, are effective insulators that minimize heat transfer from the soil surface to the underlying soil. |
| It is almost as effective as the thermal paste at helping heat transfer between the heat sink and the processor. |
| The AVR4 vaporizing regulator is heated via an electric heat transfer element. |
