How to Use a Thermal Camera for Home Heat Loss

Most buildings have significantly higher rates of air leakage than are necessary, resulting in wasted energy, poor comfort and even health issues. In most cases, these drafts and losses are caused by poorly designed or built features such as doors, windows, attics, ducts, exterior outlets and connections to plumbing and other services. The ability to see the thermal signature of airflow through these gaps and holes allows home inspectors and assessors to identify problem areas easily, leading to helpful advice on the best improvements and repairs to stop energy loss.Go here

A thermal camera uses infrared (IR) to detect temperature differences. It can show hot or cold objects, and in some cameras the colours of the images are displayed in a colour palette – this is particularly useful to help make it easier to spot heat loss around windows and doors.

The resolution of a thermal camera is important – it can vary between 60 by 60 pixels more common on handheld cameras, and 320 by 240 pixels more commonly found on smartphone attachments. A high resolution is required to accurately and clearly identify small differences in temperature.

When using a thermal camera indoors, it’s best to use it on a day when the outside temperature is significantly warmer than the inside of your home. This is to ensure that any significant heat loss can be seen, and to avoid the heat of the sun affecting the results. You should look for warm yellow or white colours, which would indicate that your heating is keeping the air in your home and not escaping through gaps and cracks. You should also watch out for cold blue colours, which could be areas where the draughts in your home are being created and heated by outside air.
