Bought myself a new tool.....trying to get my heating bills down to a sensible level.got the cavity wall insulation boys coming tomorrow so that should help.should be able to measure the difference with the "infrared temperture probe" bought today at lidl for £17.99...tryed it on mrs red and it works well :lol :lol :lol......will also work well on fazer exhaust down pipes to see if all cylinders are up to temp .....dos'nt mention that in the instructions though :rolleyes
One, is never going to be enough.....
