Why do all the showers in America, except for those in hotels and motels, run out of hot water? Is the combi-boiler unknown over there? Is the device unique to Europe?
The combi-boiler is an ingenious device that takes mains fed cold water, and heats it up to supply the household hot water system; as long as you have gas and water, you have hot water, ergo, your shower never runs cold. I do know what I'm talking about, I have one in a cupboard in my bathroom! All this, and it runs the central heating system too!
The reason I mention this, is that I've just been re-reading some of Losgud's stories, and I think in every one I read, there's a scene where the main protagonists are enjoying a shower, and the water runs cold. Either that or one protagonist showers, leaving no hot water for the next.
I'm not just ragging on Losgud, I can't recall a story on SoL, (and I've read a lot!) where there was unlimited hot water other than in a hotel or motel scenario. Is US boiler technology so far behind us here in England?
