    Picked up a Flir E4 yesterday and have been playing about with it.

    Already discovered a sticking zone valve on my central hetaing circuit which was allowing DHW to pass through, also identified two drains on powered appliances, I guess an eenrgy monitor would have done this also but just been experimenting as you do with new gadgets.

    What else have you found thermal cameras good for?

    Missing insulation, draughts, water leaks structural cracks in masonry, electrical faults and a lot more

    Damp to cavity wall insulation?

    It will find damp in solid walls, unlikely to find wet CWI but will locate missing insulation

    I use my flir to inspect my beehives in winter- though probably not a use that everyone would have...

    Anyone with any experience with 'Seek Thermal' smartphone thermal cameras?

    Previously, Flir seemed the only option. Now Seek are a bit cheaper and with a higher def sensor.

    Usage will mostly be looking for cold bridges and insulation gaps. Also, finding hot spots in electrics (same as Tony's list above).

    I used the cheap, cheerful and Chinese work camera to find out whether a hedgehog was hibernating where I thought it would.
    Accidentally I was very impressed with the thermal output of the compost heap.

    I use an ir laser thermometer it picks up electrical, thermal bridging , missing insulation , draughts,

    If you get the right environmental conditions it can be a very useful tool indeed, you can find some basic training online which will help you understand the basics and limitations.

    The flir E4 also shares the same hardware as the E8, which is a jump in capabilities.

    Thanks Newbuild, I've ordered a Seek Thermal Compact camera. If sensor resolution is important, it's 206x156 (compared with the Flir's 80x60). It's supposed to be an xmas present but I'm not sure I'll be able to wait that long!

    The purpose is to help with tightening up heating demand on a refurb (i.e. to achieve the 20kWh/m2a EnerPHit standard).

    I have had a Seek attachment for my android phone for say 4 years and it is brill for the stuff being talked about here. Cannot be to high resolution though.
    It was I think from Amazon warehouse and just over £100 over half of fresh boxed one.

    Seems pricing has gone up sharply if anything from a quick amazon review.

    Prices have gone up since demand rose and supply could not catch-up. (IC shortage).

    Resolution is important but so is temperature differential.

    You can try blasting the heating, which will reveal damp spots as those will warm slower. You can also try running the heating for some time, letting everything get to temperature then having a look around late at night or early morning once any solar gain has gone.

    I use a Flir for viewing my bees inside their hives in Winter... quite a niche use though, I admit.
