Gerry from Precision Temp sent me a replacement heat exchanger and it arrived today.Â The rain let up just enough to give it a try.
Here’s the old exchanger.
I replaced the one I broke with the new one and was extra careful to use two wrenches while tightening the fittings.Â I added some water to the Jr. and ran the pump and watched for leaks.Â Looks good! 🙂
Here is the replacement exchanger put back under the kitchen counter.
Next I had to pump a couple of gallons of water out so I could put the non-toxic antifreeze in.Â I topped it off with water and hooked up my BBQ grills propane tank to give a test.
After a few minutes of the Jr. doing its thing we had heat!Â Nice and quite coming from all three resgisters.
Just a couple of loose ends to button up on the Jr. system and it gets a DONE stamp!
As soon as I get some time I’ll hook up some water to the trailer and test for my instant and endless JR. hot water supply.Â Stay tuned.
