Removing a Bit of Air from a Third Floor Hot Water Radiator: Infrared Video

Gordo

Most of the time, when I set these infrared videos up, something happens and the "take" is blown: The camera dies. The customer holds their thumb in front of the camera. The pressure dies before the air is fully removed. The barking dogs/children move into the scene, etc etc etc. You only get one chance to capture the moment, or its gone.

You be the judge, of course, but I think I got a good one this time....

Solid_Fuel_Man: Thank you for your comment!

I can see why one might miss that the posting above is in fact a video and not just a badly composed, oddly colored still photo not worth more than a passing glance.

Otherwise, it is just a "vox clamantis in deserto."

Really great! You could use a tripod and let the customer off the hook

Really cool to see how the water flows through the rad I wish I would have had a video like this a few years ago when arguing with a salesman about why I should re pipe the rads when doing a steam to hot water conversion in a really old and very nice house to prevent the pipes from freezing in the winter

Cool video. I mean,Hot video.

"Really great! You could use a tripod and let the customer off the hook"

Well, I usually have the customer hold the camera so they can see the immediate results of what I am doing for them, a sales tool, if you will. I exaggerated a bit about thumbs in the way (but not by much)!

@tomhaeussler : I know what you mean! This FLIR has been an eyeopening experience.

I'd had never suspected that flowing water would react that way in a partly filled radiator. Usually, when the pressure drops and air seeps into the radiator on the top floor, AND the supply is at the top, the flow stops and the radiator is cold. Period. Well, now I know its not quite that simple.

I'm sure eventually if pressure kept dropping, the flow would stop and the radiator would go cold.

I wonder why the Dead Men did that top supply thing anyway on top-most floors?
At least if you lose pressure over the season, and you have both hook-ups at the bottom, you won't totally lose flow unless you had a major problem.
