From my experience I’ve learned the following: the heat loss calculation is definitly an estimate. For starters the u values of the materials and t...
you can play around with the answers to get to the right value. Like you I already knew the heat loss so I changed the build year until I got the righ...
You might want to give Boxt.co.uk a try. At least for me they had octopus level price, but were able to proceed quite quickly. They also give an upfro...

just some comments by a door blower tester that they have never seen a higher value than 1 and the fact that in my calculations I could only get close...
I agree, it is weird that we are suppose to trust this whatiffery, but not our own usage data. after all, as was stated above, assuming a linear relat...
