An energy auditor's top 4 uses of non-contact infrared thermometers

1. Identify inefficient appliances

Most electrical appliances will produce ‘waste heat’ when switched on. This is because all the components inside them are not 100% efficient and the wasted energy is typically converted to heat. As such, inefficient appliances often produce significantly more waste heat than efficient ones (for example, hot halogen down-lights, poorly insulated ovens, and so on).

2. Improve your comfort

Radiant temperature is a very important aspect of thermal comfort. Use your infrared thermometer to identify what parts of your building are letting in too much heat in summer or sucking it all out in winter. Measure the surface temperature of a window and compare it to an internal wall. Can action be taken to better manage heat loss or heat gain through the window?

3. Reduce your heating and cooling costs

Most people will find a temperature of 24-26 degrees C to be pleasant in summer and 18-20 degrees C suitable in winter. These are good levels to have your air conditioner set at. Setting the air conditioner lower in summer typically does not make it work any faster: it will just use more electricity because the compressor will remain on for longer. As a rule of thumb, a one degree temperature adjustment can save around 10% off your heating and/or cooling costs.

4. Reduce your refrigeration costs

Refrigerators and freezers often remain set to their over-spec factory settings. To measure the fridge or freezer temperature, point the non-contact infrared thermometer at an object inside. A temperature of around four degrees is recommended for your fridge and as ‘warm’ as  -12 degrees C is suitable for the freezer. Adjust the settings on your unit as appropriate. A freezer temperature of -12 will safely store foods for relatively ‘short’ periods (2-3 months) whereas the factory settings of around -18 degrees can store food for much longer periods, but this is unnecessary in most situations.
