I have at last been investigating the plumbing in my home - we moved in about 18 months ago. I wanted to see what routes the pipes take. The property is a bungalow and all the heating pipes run from the garage at ceiling height into the loft space over the living area. From there the heating pipes descend mostly through a cupboard and into the floor.
The pipes are mostly hidden under the 2-2 inches of fibreglass insulation. When I moved this insulation to see the pipe runs I found that none of the heating or water pipes had any lagging. They are just bare copper under the fibreglass insulation. I know the heating was either installed or upgraded in 2011 (at least that is when the boiler was installed).
Would you advise me to insulate these pipes or does the fibreglass mat covering comply with any relevant regulations.
There are two sets of heating pipes. One pair (22 mm) is for the radiators. The second pair (15 mm) is for two towel rails and a radiator in an airing cupboard. Until recently the towel rail pipes were fed from the unzoned pumped heating and the other radiators fed from a zone valve controlled by the hall thermostat. The zone valve has been removed and all of the radiators now have Honeywell Evohome TRVs.
There are two 15 mm heating pipes (flow and return) in an cupboard which are very close together (about 15 mm)and I am doubtful that I would be able to get standard insulation on both of these
The hot and cold water pipes are both 22 mm. There is a hot water circulation pump which we do not use as it is not switched (just plugged into a 13 A socket) but does not help enough to get hot water to the far reaches of the property.
to warrant its use.
If the advice is to apply pipe lagging, what sort/supplier would your recommend as being cost effective. [Note there is one section above a utility room of about 2 metres which is inaccessible (there is less than a 50 cm access gap between a wall and the roof joists).]
