I was wondering what the group thought about the economy pipe lagging versus byelaw version?
I notice that Tool station say the economy lagging cuts up to 70% of heat loss, whilst the byelaw description says it cuts over 75%.
At first I wondered whether it is worth the extra expense to save 5% heat loss?
But now I read the descriptions again, I notice it says up to 70%, implying that under ideal conditions the economy version will reduce heat loss by 70% but in other conditions it might be less; in other words, 70% is the maximum performance of the product. Whereas the byelaw description says over 75%, implying the 75% is a minimum figure and in ideal conditions the savings could be greater. If this interpretation is correct, it could be that the difference between the two products is more than 5% and worth paying more for.
What does the group think?
