It can leave one vulnerable to the cold or to wild animals or even just the mother-in-law eyeballing your junk. It's not always about having hot water.

Perhaps solar water heaters still cost more than the old gas water heater. If they develop leaks and wear out just like gas heaters, they will probably not be any cheaper than old technology.

I wonder how many gallons they had for each guest. I assume they had regular hot water heater for kitchen use. Dishes washed with cold water might be a little greasy.

Never bother to investigate. The hotel was about 7 or 8 stories high. It was perfectly fine on a sunny day. > I wonder how many gallons they had for each guest.

Well, stop it. You've posted to 4 disparate groups, have you read any of them? Two threads up from this in alt.solar.thermal is some nice information on tanks that can be solar fed.

You don't buy a solar collector because it's cheaper, you buy it because it costs less to run and is less harmfull to the environment. Do some research, formulate a question better than "Wonder if they stink", and you might get somewhere. Your choice. Jeff > |
