Using thermal imagers in the summer 5 Replies

Too many thermographers leave their imagers in the case during the summer. This comes, in part, from the way we used to work when imagers were not nearly as sensitive and our understanding of how to use them was limited to winter work.Get the darned…Continue

We're with John--thanks for creating this group, Michael. Excited to share thermography information & infrared images with group members! Hope everyone has a great weekend.

I completed my Level I training 5 weeks ago and I've had my camera for 4 weeks. I've audited several homes with the IR and Blower Door. I look forward to learning more about what works and what doesn't.

Thanks for starting this one Michael. It looks like Home Energy Pros will be a great place to hang out, especially once the groups begin to sort themselves out and we all end up in the best places.

As many of you know, I've been using thermal imaging since 1983. At that time, working as in the Residential Conservation Service (RCS), a program funded by utilities to reduce electrical usage, it became clear that without themography, we just could not get the job done correctly. At that time we barely had blower doors! The first I used literally required a truck to move it around. We've come a long way.

I've recently been working with my colleagues and a number of our customers to find out how we can use thermography literally 365 days/year, pretty much anywhere in the country. This was not possible in the past mainly due to the limited capabilities of the imaging systems. But many of today's systems are so sensitive that "IR365Anywhere" is now a viable option.

What is required? First, having an imaging system that has thermal sensitivity of 70mK or better, preferably 50mK. Second, MASTERY of the imager, especially knowing how to manually adjust level and span. Third, understanding heat transfer basics and how residential buildings work. Fourth, picking and choosing your time of inspection—clearly this is a limitation for some people for parts of the "365." Finally, having the option to manipulate the environment using either the heating or cooling system and a blower door.
Will it REALLY work everywhere all the time? No, but my experience over 28 years tells me, by following these simple guidelines, we can be successful at finding insulation issues at least 95% of the time and air leakage at least 99% of the time. If nothing else that leaves us room to grow. On those few days when we cannot see what we need to, we should be able to at least learn something about why it didn't work and that also has great value!

I'd invite others to chime in with their experiences, positive and negative, so we can all learn from each other. The one thing I do know is I still don't know it all!

I've already noticed a few folks sharing thermal images of their work in the photos section, so I thought that perhaps they may be interest in an official infrared thermography group for HEP members.
