When is the Best Time for a Thermal Imaging Survey?

Over the years, thermal imaging surveys have become an increasingly popular and essential tool for identifying hidden issues within a home. A thermal imaging survey is a non-invasive inspection that uses an infrared camera to detect temperature differences on surfaces, making invisible heat patterns visible. These patterns can highlight problems such as missing insulation, leaks, damp and mould growth, issues that are often undetectable to the naked eye. However, the effectiveness of the survey is largely influenced by the timing of the inspection. In this article, Ignite Property Group examines the key factors to consider when selecting the optimal time for conducting a thermal imaging survey.

What are the Optimal Conditions for a Thermal Imaging Survey? 

For thermal aiming to work effectively, there needs to be a thermal differential. The stark difference between temperatures allows the thermal imaging camera to pick up on the larger difference and pick up any sides of draught, missing insulation or leaks. 

Which Season is the Best for Thermal Imaging? 

Here in the UK, we generally experience all four seasons to varying degrees. Understanding the seasonal variations and their impact on the accuracy and reliability of a thermal imaging survey is crucial to maximising your results.

Winter – November to April:

Winter presents the absolute best conditions to complete a thermal imaging survey due to significant temperature differentials between the interior and exterior of homes. Cold outdoor temperatures provide a sharp contrast to heated indoor temperatures making it easier to identify areas of heat loss within the home.

Autumn: 

Autumn is largely considered a transitional period with more moderate temperatures. This means that during this season, there is a more balanced thermal environment providing that there isn’t excessive sunlight or rain which may distort survey results.

Spring: 

Like autumn, spring is another transitional season that, providing there are no extreme weather conditions during this time (which can’t be ruled out here in the UK), can also provide accurate thermal imaging surveys.

Summer: 

While summer provides longer and more pleasant days, it poses significant challenges to completing a thermal imaging survey. The reduced contrast in temperature differentials means that there are large anomalies in accuracy. Ignite Property Group can, however, offer manual heat loss surveys during this period to identify risk areas and help prepare for the colder months ahead.

Which Time of Day is the Best for Thermal Imaging? 

The time of day can significantly impact the accuracy of a thermal imaging survey. For instance, solar influence can impact results heavily. When the sun is low on the horizon, this minimises any potential interference caused by solar heat, allowing for a clearer thermal image.

The best times of day for a thermal imaging survey are:

• Early Morning, before the sun has fully risen, meaning the house has cooled down overnight and no interference from the sun’s low angle.
• Late evening, after the sun has set, allows the exterior of your home to cool after the sun’s exposure in the day.

It is also best to operate a thermal imaging survey while your home is occupied. This ensures that should you have any heating on or any electrical appliances, the survey can capture their thermal performance and any irregularities during a normal usage period.

As previously mentioned, weather conditions also have a significant impact on the work completed. A stable outdoor temperature is considered stable and is more preferential. Any sharp fluctuations can impact the results and make it challenging to identify any anomalies. Likewise, high rainfall or humidity can affect thermal patterns and cause false readings.

When to Book Your Thermal Imaging Survey

Choosing the best time for a thermal imaging survey involves the consideration of multiple factors. Winter offers optimal thermal temperature differentials, whereas spring and autumn can also provide a nice balance. When you get in touch for a thermal imaging survey, our team will let you know whether this is a possibility given the seasonal trends and general weather conditions, however, Ignite Property Group can also offer manual surveys during any down periods.

By using a qualified thermal imaging service provider such as Ignite Property Group, homeowners can make informed decisions to enhance their energy efficiency and address any potential issues to save time and money. Book your survey today to let us help you.

Frequently Asked Questions (FAQs)

1. What is the best time of year to book a thermal imaging survey?
The best time for a thermal imaging survey is during winter, when indoor and outdoor temperature differences are highest. This makes it easier to detect heat loss, insulation issues and damp. Spring and autumn can also be suitable if the weather is dry and stable.

2. Can thermal imaging find heat loss or damp in my home?
Yes. A thermal imaging survey can detect hidden heat loss, cold spots, poor insulation, damp areas, and even leaks in walls, roofs or pipework, problems that are not visible to the naked eye.

3. How long does a thermal imaging survey take and what do I receive?
Most residential surveys take about one hour. You’ll receive a full thermal report within 48 hours, including images, expert analysis and clear recommendations.

4. Does weather or time of day affect thermal imaging results?
Yes. Ideal conditions are cool, dry weather with minimal sunlight. Early morning or evening surveys produce more accurate thermal images by avoiding solar interference.

5. How much does a thermal imaging report cost in the UK?
A thermal imaging survey typically costs from £250 for a flat and from £299 for a house. Costs may vary depending on property size and location.
