I've just had an external condensing oil combi installed and it had to go at the back of the house.This makes the pipe runs which go via the loft space to the taps (at the front of the house) very long.
The installers fitted the usual foam insulation but I want to improve on it and keep the hot water in the pipes hot for a bit longer
What can I use that's a lot better than the usual stuff
