Don, even though it isn't that hard once you get into the job, it seems very intimidating at first. Not everyone has the same skill set or confidence level. With that said, you sure did a nice job.

That is very close to where it needs to be...those gauges aren't exactly 100% accurate either.
If you really wanted to you could throttle the circulator a little on the outlet side, it will slow the flow and might even decrease power consumption? less gpm = less KWH? Makes sense to me but might not pan out in practice.
