Hi, I have an unusual question. When I switch on my hot tap, am I right in assuming that the hot water will be delivered solely to my hot tap? even though the path of the hot water may pass through multiple tee’s on the way (which will have cooled water at their other connections). I expect the some water will loose some heat along the way by coming into contact with the stationary cooler water, however I’ve got a geeeling that an entire leg of my hot water system ( which should be stationary ) is being heated at the same as the desired hot water route to my tap. I’m thinking this as I’ve recently tee’d off my main kitchen hot water pipe and now this tap is taking ages to get hot. I’m convinced some other body of water is getting heated up??? Really appreciate any thoughts /suggestions. ??
