Even if you've never had to take cold showers in the summer, I have. I'm not sure why you can't believe our experiences would differ. The only reason I mentioned the USSR at all is because when I asked in China they said they got the system from them (and south of the Yangtze, you don't even get that).
Not sure what is your point. You've mentioned USSR and it was wrong, as Soviet System has never been like that - "hot water only during the winter". Ergo, you should not have brought up USSR.
