14 year old thread revival!
Finding ways to save money never gets old...especially now Tories are preparing Austerity 2.0.14 year old thread revival!
Doesn't matter what your politics is, everything is still more expensive.
I plan also to ban use of the tumble dryer and put our heated drying rack in the lounge to heat that room.
Except chocolates - I remember buying one of those plastic tubs of Quality Street six years ago for £3.99. They were marked up at the same price the other day.
Today's tub will be very much smaller.
We don't have any issues in that regard. The heated rack has been used in the next room for many years and not resulted in any decay.
If you've got an insulated cavity wall then they will save you pennies a year.
Which is pretty obvious if you think about it. The reflectors try to prevent the hot spot of heat from the radiator transferring to the wall directly behind it. If the wall is a good insulator then it doesn't matter much if the inside side of the wall gets hot.
I tried it on mine behind radiators on outside walls that were cavity insulated and it made no detectable difference at all.I have CWI, but none the less I have had my eyes open for a roll, if I spot one. I have four rads fixed on outside walls and despite it not being suggested to save much - I fancy it is understated.

I've read that, but also seen comments where it helps make those rooms warmer.
Detecting a difference is incredibly difficult, with so many variables to work with.
wobs, honestly, you are free to believe whatever you want, but, to remind you what you said; "All else being equal, you can get better thermal performance with as thermnal (sic) mass with insulation on the outside. You need far less insulation for the same thermal performance."I'm aware that the u-value doesn't change.
I am not suggesting you keep the heating on all the time. In fact leaving the heating on 24hr is the opposite to what I am saying.
Its about using the thermal mass to release heat back into the house after the heating has gone off. The experiment above shows that this is a more efficient use of materials than having insulation on the inside of the walls or a light wooden frame.
The above quote clearly says "30% more fuel-efficient......and that despite having 33% less insulation in the walls."
