The manufacturer no longer makes the heater, 26-00143 & 26-08143.

Quote : "The closest thing we have would be the E2300-0300ET. You will have to cut the plug off the power cord and maybe the P/S cord too. But it is all we have that will work for the 26-08143. The 26-00143 is the same thing but without the P/S and the cords and the box. It’s just the housing and element with plastic."
