last winter i just couldnt get my settings right to shut off pump in a short time after turning tap off at brush end with hot water resulting in blowing up my orange thermobore!
red thermobore plus is slight bigger diameter and its doing the trick.no extreme pressure building up in the boiler.granted its heavier than standard thermobore but its very good hose IMO.it certainly doesnt ever kink with hot water pumping through it.well happy!
