WarmteScan (HeatScan)

Sagging insulation and construction faults cause heat loss in your home

In older homes, for example, heat can be lost due to sagging insulation. Heat loss can also result from construction defects. Often, it is not visible to the naked eye how and where this heat loss occurs. These heat leaks cause extra heating costs. If you want to effectively preserve your home, these heat leaks will have to be detected in order to address them.

A WarmteScan can detect heat losses in your home

With a WarmteScan, heat losses in your home can be detected. With a special (thermal image) camera, which converts temperature into colours, heat leaks become visible. For a good thermal image, there should be at least 10 degrees difference between inside and outside temperature. And there should be no interference from sun rays or precipitation. Conditions are therefore best early in the morning in winter or when it is cloudy.

De beoordeling van een WarmteScan vraagt om vakmanschap

To make a WarmteScan, setting up the thermal imaging camera and interpreting the infrared images requires skill. The colours on the thermal image cannot simply be translated one-to-one into heat loss from facade or roof. Aluminium, for example, looks very different from brick at the same temperature on a thermal image. Also, translating thermal images into sensible energy-saving measures requires building knowledge.

How the Woondokter WarmteScan works

Woondokter's advisers make an appointment to carry out the WarmteScan. We schedule these appointments between November and March, because for good heat photos, the temperature outside should not exceed 10 degrees. Moreover, it should not rain and there should be no direct sunlight. The shots for an exterior WarmteScan take about 45 to 60 minutes. If we need to take a WarmteScan of both the outside and inside of a house, it will take about 60 to 90 minutes. There is an additional charge for photos of the inside.

Using a professional thermal imaging camera, we take pictures of the outside of your home.  With thermal images, we can use colours to understand, for example, the location of insulation problems, air leaks, thermal bridges as well as moisture problems in the facades or roof of your home.

After the appointment, we will send you a written report with the thermal imaging photos taken and an explanation of where the heat leaks can be found. This will give you an indication of the possible causes of heat loss in your home.
