My latest Shabbat water urn is dying. They don't seem to last long. I've tried expensive ones, cheap ones, pump tops, spigots on the side, just about all of them. They seem to last between 2-5 years.
My mother in law thinks I'm silly. She says to get a cheap one each year at Pesach, throw the old one away and use the new one all year until next Pesach.
The cheap ones don't get the water hot enough, the push pumps get pooped out after a short while and the expensive pretty one from either Revere or Farber (can't remember) was always being repaired for $35 per fix.
There was a Jewish company in Massachusetts someplace that made a pot that they insisted was as hot as permissible. That was wonderful and lasted over 5 years before the pump thing kept getting stuck. They don't seem to be in business any more.
Anyone have a suggestion? Please don't suggest the Japanese pots with the electric mechanisms that Costco has. They are wonderful but cannot be used on Shabbat.
