I’m fortunate to have a hard and fast contract since 2019 and have till October 2023 earlier than the huge improve in power prices hits me. I’ve been on a quest to cut back our use of electrical energy and gasoline in hopes of offsetting the worth improve subsequent 12 months.

Thus far, I’ve checked out:

This assessment is a little more on the intense facet of issues. Whereas it is fairly logical to make use of a thermal imaging digital camera to attempt to determine poorly insulated components of your private home, the issue is that these gadgets price some huge cash. The HT-19 infrared thermal imager I used for this experiment prices over £400. I would want to have the ability to make some vital financial savings on my heating invoice to justify this. Even the favored FLIR cameras on your telephone will set you again over £200.

My residence

In a sure context, my home is a typical brick-built UK terraced property. It’s approaching 100 years. It had triple glazing put in about 20 years in the past, and the partitions have been insulated. I additionally not too long ago had a brand new roof that went from a chilly drafty roof to a heat roof design.

Despite the fact that many issues have been accomplished to the home to enhance insulation and effectivity, it’s nonetheless an outdated home with drafts and inadequate insulation.

Utilizing the outside digital camera to determine scorching spots

Utilizing the digital camera open air revealed nothing that wasn’t already apparent. Home windows and doorways had been scorching spots. Window edges are the primary scorching spots. You may even determine the CCTV cameras I’ve unfold round the home.

There have been a few spots the place the crimson scorching spots prolonged farther from the door or window frames than I anticipated. My again door might be an issue space, I feel the door has fallen off the body a bit. It isn’t one thing I used to be personally conscious of, however one among my door adjusting pals seen it instantly when he bought shut and did not want a digital camera to verify it.

Utilizing the digital camera indoors to determine drafts

Utilizing the digital camera indoors to determine chilly air coming in by way of drafts is by far the best approach to make use of this digital camera (in my view).

Though I’ve discovered it helpful on this state of affairs, I would not say spending over £400 on a thermal imager yields considerably higher outcomes than utilizing some widespread sense, which ought to come free.

The perfect instance I discovered was the inside door that we’ve got that opens to the place the entrance door is. This can be a widespread design in UK houses, appearing as a buffer between the coldest outdoors door. The home windows on this inside door are ornamental and single-pane, and that is not one thing I am going to be capable of repair any time quickly.

All doorways have chilly spots across the edges and home windows, however this door clearly has a drafty spot on the left facet of the door. For this I utilized an eraser excluding silicone backside seal, which I purchased on Amazon for round £8. Because of the design of the door, I am undecided it is going to keep in place, however it clearly has helpful outcomes. The darkish blue stain that stretched away from the door is considerably lowered. The crimson spots you see are the place I briefly knelt down to use the stamp.

Value and different choices

I paid £480 for the HTI-19 Thermal Imager, which is some huge cash. That is over two months of gasoline and electrical and possibly a number of months of gasoline alone. So it might take a very long time to see a return on funding for this.

A lot of the competing handheld thermal imagers price upwards of £400. Something under this value appears to get fairly dangerous evaluations.

The competing possibility is cell phone cameras. FLIR is by far the most effective model for this selection. You may get the FLIR ONE for as little as £207 or the Professional mannequin for £428. I used to be delay as there are lots of combined evaluations and the FLIR ONE Android app has fairly dangerous evaluations.


My outcomes haven’t been as revealing as I had hoped, however I’m not discounting the advantages of utilizing a thermal imager to enhance the effectivity of your private home.

In my case, it clearly recognized areas that permit out warmth or let in drafts, however they had been all simple to guess. Even after I utilized options to enhance insulation, the outcomes had been fairly apparent.

I suppose the digital camera would have been extra helpful if there was a particular downside space inside my home that was instantly apparent. Maybe an ill-fitting window may have been fastened, and the ensuing price financial savings would justify the price of the digital camera.

For residence customers, I feel you might be certain you are not lacking out on a lot by not utilizing a thermal digital camera to pinpoint downside areas inside your private home.

Clearly I’ve solely seen this as a house owner utilizing it in my particular person residence. When you plan to make use of this recurrently throughout a number of properties for a enterprise, then the price of the system is much less of a difficulty.

I might say one thing like that is price borrowing when you’ve got the choice too, or possibly you can do some form of group purchase between pals or household. I might fortunately break up the fee with ten folks.
