Last weekend I attempted (for the first time) to winterize a vacation home.
I (1) shut off the inlet & outlet valves to the electric water heater, (2) shut off the feed line coming into the house, (3) drained the system by opening a valve at a high point and opening a drain valve at the lowest point, then (4) reopened the inlet & outlet valves to the water heater. I could find no way to shut off (or even lower the temperature of) the water heater.
So I think I've got a full water heater, open to the (empty) inlet & outlet lines, that is still keeping the water hot. (I was told to keep it full to prevent corrosion. It is in a poorly heated area, so I kept it heated lest it freeze.)
Since then a worrisome thought has occurred; Will it now boil itself dry, since no new water can come in? If it does, is there some sort of safety that will turn off the electricity (or have I created a fire hazzard)? In the process of boiling itself dry, will it fill the (closed) plumbing system with live steam, and is that a problem?
Obviously, I need your advice / help.
Thanks,
