i just use a premium metal hose reel from gardiners called a claber reel.cheap as chips(£37).very light and has been problem free for 2 years.i dont think it would be suitable for hot water though.no it doesnt rust!and fits all of my 100m of thermobore no problem.
Hi tim I don't mean the outside its the internal plumbing where the water travels through , what's the internal made of on the reelworks ?
