Question 1

A double glazing salesman also used this device "to check the % heat going out". Can it do that?

Accepted Answer

I don't belive it can to any real degree of accuracy. What it can do is measure the temperature of the glass and also the room temperature and so allow you to calculate the difference, but you would also need to know the readings of a double glazed unit under the same internal and external temperature conditions. Humidity would probably also play a part. At best I wpuld say it could give an indication, but the state of the window seals and if single or double glazed would tell you that anyway. The machine is best used to check for cold spots, thermal leaks, etc.

Question 2

Would it be able to detect body heat from rodents behind a plasterboard wall

Accepted Answer

Sorry to hear of your problem.  The thermal leak detector works by directing the user towards the loss of heat, rather then finding heat sources.  If you have a rodent problem, they are getting into the property from the outside.  Maybe a close scrutiny of all possible access points would be helpful.  Rats and mice can squeeze into a very small hole, so pipework, cablework, a hole around a window covered by greenery would be my first areas to search.  If no children, maybe ask an expert about a suitable solution.  Wishing you well.

Question 3

Can this be used to accurately measure floor temperature? I want to check if my underfloor heating temperature probe gives me an accurate reading.

Accepted Answer

The floor temperature measurement will be as accurate as the wall temperature measurement. Phone Black & Decker for the claimed accuracy of the instrument.  Mine gives a reading accuracy of one decimal place ie floor temp = 20.1

Question 4

Can you use this item outside aswell please to detect how much heat the prperty is lossing

Accepted Answer

I have only checked from inside for heat loss,I suppose it would give a reading
