I'm starting to have some possible issues with my Geyser HPWH, but they don't make them anymore. Is there any company that makes a similar product? All I can google are hybrid tank types.

The after-market heat pumps for electric water heaters have all pretty much gone away, since they can't come anywhere near matching the efficiency performance of the current offerings of fully integrated heat pump water heaters, now running EFs north of 3.

Thanks. I've been searching and can't find anything. The geyser has been online for almost 8 years heating a 16 year old Rheem 50 gallon water heater. Maybe it's time to consider an upgrade. Local power company rebates go away in May.
