Power Saver

Energy leaks can be avoided by simply making right choices when it comes to insulation solutions around your house. It is estimated that approximately 40 per cent of current emissions comes from the choices we make as individuals. Saving energy means less CO2 emissions and in result preserving the environment for future generations.

With annual energy costs constantly increasing, by improving the insulation and eliminating thermal leaks around our homes, we can save a significant amount of money.

The Black + Decker TLD100 Thermal Leak Detector is an ideal product to easily identify areas where energy leaks occur.

Easy to Use

The BLACK+DECKER TLD100 Thermal Leak Detector is easy to set up and use.

Simply point the detector and shine the light on the wall in order to set the reference temperature. Then move the light around your house. When the temperature changes by 1, 5 or 10 degrees Celsius (user adjustable), the light will change to red or blue to indicate a hot or cold spot.

Multiple Applications

BLACK+DECKER TLD100 Thermal Leak Detector can be used not only to detect hidden energy leaks around doors, floors, walls, pipes, windows but also for many other tasks around the home:

– Check the temperature of surfaces you can’t touch

– Check whether your HVAC is working properly

– Diagnose engine misfires

– Check ceiling insulation around recessed lights

– Check for drafts around the fireplace

– Check that your fridge and freeze settings are correct

    I bought this to prove that I had an unsatisfactory window fitted. …it help me prove to the window maker and fitter that the new window he supplied me was not up to modern standards re draughts etc. Perfect!

    Amazing bit of teck this will find any draft around the home or any were else . Not only does it find a drafts it’s tells the temperature . You can even find out if you have insulation in roof space or wall’s just by pointing at wall’s if it’s stay red great if it turns blue may need further investigation great value will save you money

    Golden Review Award: 2 From Our UsersJust had an extension to the house and gone open plan – but suspected insulation hadn’t been installed correctly as it didn’t feel as warm as the rest of the house and was considering underfloor heating to resolve the problem. Bought this to check if the builders had insulated the extension correctly and it turns out the extension is the warmest place in the house – all the drafts and cold air is coming from old part of the house. All I needed to do was to insulate the old part house properly – happy days!

    Very clear to see where hotspots and cold spots are in a room. Easy to use, seems to be accurate.

    Good gadget, but had to return as it was not what we needed it for… No problem with the item its self. As we didn’t realise you couldn’t use on people. So will not give it a bad review. So that’s fair.

    Was able to pick out the areas in the attic that weren’t insulated properly from room below. Also identified a draught in the bedroom were the caulk had developed a split. Really impressed with this and the different coloured lights make it fun and easy to use.

    Has been very helpful to find those cold spots in the house that require more attention. So instead of reinsulating a whole area, I can just target the small areas of cold.

    A bit pricey, but will save you money in the long run targeting the cold areas

    Golden Review Award: 2 From Our UsersI bought this to check our new doors and windows for good seal, it found the leaks with ease, it showed many leaks around the frames and fittings, which did not go down well with the installer who tried to wriggle out of their obligations until I produced this tool and told them to check for themselves … A great purchase even if I only use it once its paid for itself as the contractor lost out on 1800

    Golden Review Award: 2 From Our UsersBrilliant product. I bought it for checking on damp – using with a damp meter too. Thoroughly enjoyed myself doing the whole Mysterons routine with the light and then checking the results. Easier to see at a glance the results – more so than the damp meter used. Showed up lots of cold patches around the home. Invaluable, really. Particularly for an amateur as it’s easy to bamboozled into household repairs.

    Golden Review Award: 3 From Our UsersI was not expecting much as this was priced much less than similar products but it has exceeded expectations. Does exactly what it says, point it at the central heating and it glows ready, at the window it glows blue indicating a draught. Hope to use it to fix draughts in my home as my gas bill is too high, in summer when the AC is on and in winter when the central heating is on. Finally the device is high quality and feels so.

  16. Avis9770ecxk says:

    Yes it works fine – not sure I have learned anything I didn’t suspect already. Has confirmed that the rubber seals around some d/g doors needs replacing. For that, it’s quite an expensive purchase.

  17. LinnieSeibert says:

    Surprisingly good at spotting temperature variations from draughts and works well from a distance. I purchased to try to locate central heating pipes buried in 75mm deep screed. While a bit hit and miss picking up hot spots, the device gave a good enough clue to location. I doubt that professional devices or employing specialist contractors costing many times more would have done much better and definitely worth the low cost as a first go to see if diy works.

    Golden Review Award: 4 From Our UsersIn the absence of a proper thermal imaging device (costing thousands) this works very well. It’s also great fun to use. The only downside is that you can only see a bit of the scanned area at a time (unlike a camera) so you have to build up a mental picture of the cold spots it’s detected. It also takes about 0.5 second to detect changes so for example you can’t do a rapid sweep and see instant colour changes.
    Despite this it’s a very useful gadget and very reasonably priced.

    Very useful little tool for anyone who wants to airtight there place. This gives you a very good idea where the cold spots are and very easy to use too. Only thing is that it does not come with a battery.

    While it does not show the draughts it does highlight the cold spots clearly allowing you to plan a remedy. The lower half of my wall is much colder than the top half. (dampness or problems with my cavity wall insulation? we shall see).A cheap and easy to use tool to get the house prepared for next winter. This item should pay for itself in reduced energy cost with in the year.

    Used it for my windows and walls and it showed me the cold spots.. Its very good in that you can see where the cold spots or heat spots are, though I would not use the readings as factual only as guidance, I measured a boiling kettle it measured 80 ‘c on device, whilst my standard thermometer said 98’c (after bubbling stopped). so bit of a difference. But on other items they measured the same temperature. Therefore, useful as a guide.

    Golden Review Award: 3 From Our UsersThis is a temperature gun but has a colour code to make it really easy to see where you are getting cold drafts in. I went around my house and found all the cold spots, did a lot of draft proofing and the difference in the temperature of the house is very noticeable and also the boiler is working less often so i’m saving money. Only problem is once you’ve done the job then there isn’t much need for it although I did use it to check the temperature of my radiators to see if they needed a power flush.

    Bougt this to hunt down draughts and cold spots. After using it during the cold spell just gone, the only conclusion I’ve come to is to knock down the house and rebuild! Certainly found all the draughts and cold spots in the house walls and junctions that I thought were sealed against the wind and temperatures. Despite having two annuluses in the walls one of which has insulation infill I was surprised to discover that all that glitters is not gold. This Black and Decker found the lot. Now in the process of attacking the worst of the draught positions and cold spots. For anyone who thinks that their houses that have passed the official “leak” test are OK, I say get one of these B&D units and be surprised.

    Golden Review Award: 3 From Our UsersEasy to use and provides some surprises when I scan the outside walls of the house(from the inside). One downside is the poor viewing angle of the screen, and I guess the battery life will be fairly limited, but that still has to be confirmed. I reckon it will pay for itself in a year or two after checking the whole house and implementing localised fixes to insulation and draughts.

    Golden Review Award: 8 From Our UsersVery well built, I bought the Thermal leak detector to find what was causing draughts around my house I found them and am working on sorting them out.

    I find that I am just fascinated by this and just used it for silly things afterwards as I like these kinds of gadgets so I think it was money well spent and does exactly as it says on the box. I found the instructions clear and concise even though I didn’t really follow them it was just so easy to set up and use. Happy it came with a 9v battery too.

  26. NicolaCPark says:

    Happy with this purchase. It helped identify cold spots under coving that was easy enough to fix with some polyfilla. Showed just how much heat I was losing under a curtain that didn’t quite reach the floor which has now got me thinking about a thermal blind for the window in question. Showed me hot spots too. Also showed me where I wasn’t losing much heat which meant that I saved time by not having to take action in those places.

    I think it’s worth the money. Very easy to use and it came with a battery included. I’m sure family members will be keen to borrow this too.

    Golden Review Award: 2 From Our UsersGreat value.

    It’s very efective for thermal leak detection.
    The red/green/blue light makes it really easy to spot the more pronounced temperature changes.

    Just be aware that it might not be very accurate on the absolute temperature levels and the range of detectable temperatures is not as large as on other thermometers (but it’s wonderful on the range of temperatures you can find in any home).

  28. NFBMayrajvxcjj says:

    Useful to aid detection of cold spots as the color code – Red, Green, Blue beam shows the differences while you look at the target rather than watching the display. Found a fixed a few cold spots and use the standard IR function for checking home brew temps without contact.
    Just a shame you can’t turn off the light in normal mode, dog goes crazy chasing it.

    I moved into a house which we found to be very cold. The Black & Decker TLD100 Thermal Leak Detector has helped me identify the cold spots in the house and I was able to focus on these areas to eliminate the draughts /install insulation etc. I recorded the temperture difference before and after making any changes to ensure my efforts worked. You carry out the checks yourself so there are no expensive tradesmen to pay.

    Reasonably cheap and easy to operate. The B&D Leak Detector was bought from Ideabright Ltd. (on Amazon) and was received in the North of Scotland within 48 hours (No, the north of Scotland is not an Island and we should not incurr additional postage charges for being on an island, which we did not from Ideabright Ltd. Thank you for this.)

    In short; a great little product, fun to use, well worth the money in preventing heat loss or just for checking the surface temperatures of your walls, double glazing, finding draughts from damaged door seals etc.

    So the instructions are pretty useless but after a few minutes playing its easy to work out whats going on and how to make the most of this device.

    Simply point at something e.g a wall and set a reference point for the colour coding. Move the beam around and it changes colour to indicate if its colder or warmer.

    Even if you ignore the colour coding, which is just a helpful guide, you’ve got a big clear LCD screen which tells you the temperature of a given point.

    This makes it easy to find leaks in your home around windows, ceilings, floors that need insulation improving. Used well you could make monetary saving using this payback in no time at all.

    Simple, easy to use and much cheaper than a thermal imaging camera!

    This product s interesting to use to find cold spots etc, but it’s quite difficult to “aim”. After having used it a few times it was aparent that depending on how far away you are from the surface the sensor could be above or below the coloured dot. Also the unit only tells you the measured surface temperature in relation to the initial reference temp, which in itself is only in relation to ambient temperature, i.e so you can’t point at a surface and find out it’s actual temperature, so if your sensor was in a room with an ambient temp of 20c and you measured a wall which is 18c the unit will show a refernce temp of -2c. I found it a bit of fun to use but not convinced it helped me to find any real air leaks or cold spots that i could address.

    This is much more than a leak detector. Indeed it is wrongly labelled. It is basically an extremely accurate thermometer that tests the temperature of surfaces, including glass!!

    It identified exactly a cold area on my wood floor that I did not realise I had. Now covered with a large rug, the room is now cosy. The old patio doors were much colder than I realised and replacement is expedited.

    You can survey your entire house and ID hot and warm spots. For best result do it when the outside temperature is very low; with and without wind. I look forward to using it is out garden and house thermometer at all times of the year

    This may be the best value and quality product I have ever bought. It makes all non-medical/cooking thermometers redundant, especially as it is more accurate and instantaneous in measurement.

    And it is fun to use… try checking out the surface of your partner.

    Thanks to all the five star reviewers who persuaded me to buy this

    It arrived on time. It appears to indicate where my underfloor heating pipes run beneath a ceramic tiled floor. Some variations in my walls need further investigation but I have little doubt that the detector is probably correct. I need to study the instructions more closely. Then the bigger problem of what do I gain if I do something about improving my home has to be answered. I will not know until I have made any changes. Another decision to be made.
    So in all it may be a cheap but accurate expensive “Boy’s Toy” which can be shown to my technical minded friends.
    Glad that I bought it however.

    Very easy to use. First set the comparison temperature to 0.5 degree C, 3.0 degrees C or 5.5 degrees C. Then point it to a wall press the on button & it records & sets a temperature to which you get a comparison on other walls or windows. The laser on the first wall shows up green & if you point it to a colder wall it shows up blue. A warmer wall shows up red.Seemples.
