talking of dead legs on hot water pipes, doc L says you have to have lagging a meter from the boiler,
I almost never do installs so not guilty on this one, but nobody seems to do it

i remember there being something in doc l to do with lagging within 1 metre of the cylinder, but didn't realise about the boiler. news to me.
 
dam am i remembering it wrong, college days and doc L is becoming a bit blury

there are parts of doc L which did seem stupid to me, i often get call outs to tenants who think their heating is broken when they simply cant use the contols. a non doc L compliant programmer would have been far more suitable in those cases. But hey what can you do but charge the landlords for the call out
