I have a Kat's circulation tank heater I want to install on my 22RE but I'm having trouble figuring out where I should mount it and what lines to hook it up to. I was thinking about hooking it up on the output side of my heater core having the input for the tank heater coming from the output on the heater core and the output from the tank heater going into the block where the output from the heater core goes in to the block. It seems to make sense to me because the instructions say to have the output from the tank heater go into the block as far away from the thermostat as possible. Has anybody installed a circulating tank heater on a 22RE before and how was it done?
