I've got most of the parts and tools to install the A7 on the HS Tarm.
It's got a 76 gallon water jacket that is currently using #2 heating oil to heat.
If I'm not to busy this summer, I'll take a shot at installing the HX on the A7.
But first, I've got to replace a lot of old copper and corroded parts on the HS Tarm boiler.
I've promised my wife that I would replace the mixer this spring.
Maybe I shouldn't use an add-on gizmo like the A7.
I want my wife to have hot water, in case I'm not around to do repairs.
I'm pretty sure that I don't have much time left on the old ticker.
It's all loaded up with plaque. I hope to get a few more summers out of it.
Cheers,
Rich
