I think that it would be easier to seal the HX, if you didn't have to pre-twist the 3/4" 'plug' CCW.
The method used on the A7 is pretty good. See pic.
I'm pretty sure that I could make a plug in my shop, that would fit into standard 3/4" plumbing fittings. Maybe use a flare type nut fitting.?.

We don't use a lot of hot water (2 retirees) and the A7 uses less than 1 kWh per day.
Which I think is pretty dang good when compared to other heating methods..


Keep up the good work!
Xringer ,

What is the temp in the area surrounding your a7?
The HX is 25 feet of 1/4 copper tubing coiled in the tank. I like the a7's fittings, but I'm not sure I could have made the bend at the end of the loop without kinking it going thru a 3/4" pipe. The 1" plug was a pretty sharp bend but I managed.
1kw a day is amazing, my GE Geospring water heater is rated at just under 1900kwh a year so about 5kwh a day. I wish I could hook the kill a watt up to it. (240 volts)
