Did you ever do this successfully? I was considering the same thing. Same model hotsy and all. Main concern would be if it could keep up on heat.do I need besides flow switch ?
Hotsy unit 555ss
I have an heat exchanger unit and my pump is done. Figure I would a heating unit ?
Could you provide a few pics and links to models, please?I got a northern tools heater unit and use a walmart elec. pump.
Seems to work fine but the pump wont last over 300-500 hours.
For the hotsy the heaters all work the same...
The flow switch needs to be as low as possible 1/4 gpm.
Also on that elec pump you will need a bypass valve...
A kero heater will run circles around hx....
More consistent continual heat.
