I have read a lot of posts on here and other forums and still not got a straight answer.
Do central heating pipes need to be insulated. I (personally) think that pipe run under the ground floor and so prone to huge heat loss are a no brainer but what about within an upper floor void with heated rooms above and below.
There is the argument that any heat lost from the pipes will just heat the room they run within but surely the radiator does a far more efficient job of that and any heat lost before the water gets to the rad reduces that efficiency.
At a cost of £10-£15 a room the cost is irrelevant, i just want to know what is the correct (not necessarily most regularly seen) answer.
