No argument here Mark I think Most plumbing guys will have different opinions on set ups. It can be ok with check valve there really isn't much room there It looks like. I'm not big into geothermal heating I know how it is suppose to loop but that's about it.
For me it's hard to go from heating and hot water system in a home when I spend most time dealing with multiple apartments at once but that's why I'm on this forum so I don't loose the hole "smaller" system knowledge.
So the plumber did not install the geothermal system?
Your right the better way is to go on the bottom of tank with this issue.
