Hi,
In my garage (unheated) I have a new condensing combi boiler, and as a result, there are a whole load of 15 and 22mm water pipes (I think that's their size) along the walls. There are also pipes for the washing machine in there, and a sink. Lots of metal! I'd guess 10 to 15 metres in total!!!!!
None of these are insulated in any way, and I'd like to do this for economy and prevent frozen bursts.
Which ones are more important to do, hot or cold?; or, should I just put insulation on every bit of pipe. I was planning to do it with the thick blown foam tubes avilable in B&Q. Dead easy to cut to size.
Any tips?
