Ok, u r right as far as a closed system under pressure, that makes a huge difference, but I would say 98% of members here are open systems.  I later thought maybe you thought we were all pressurized...

What temps do you run your boiler at?

Ayuh,....   Draft opens at 'bout 175°, 'n closes at 'bout 195°....
It'll sometimes heat soak as it slows down, up to 210° or abit higher...
Depends on how hard the house is callin' for heat... 'n how Ragin' the fire was,...

Natural draft, usually, got a fan if lightin' a big load, 'n not enough coals...
Fan is powered off the draft door motor circuit...

Pumps are on their own aqua-stats...
The pump-away starts at 'bout 170°, 'n a recirculator circuit kinks on if the house return water drops below 'bout 150°...
Don't want that cold water, too cold...
Best havin' that condensation drippin' off the smoke stack, insteada clingin' on the firebox...

I like it Best when the oil boiler in the cellar is sittin' at 190°,...
It makes for the nicest, hottest, longest showers I've ever had,....   
DHW comes from the in-boiler coil...

Good move on keeping those return temps up, all boilers have primary and secondary loops for that very reason you stated, it's just hard to get folks to comprehend that in this part of the industry. There is to many good ol boys building boilers and selling them who know little about how they work.  We are constantly seeing folks sold the wrong parts for the wrong applications and things are rarely sized right. 

How'd you make ur handle?

Ayuh,....   It's a latex glove mold from an ole factory in S.Carolina....

I grabbed 'bout 50 of 'em when I found 'em...

I just welded a block of aluminum to it, to attach it to the latch...

They also make pretty darn Cool tail lights on a trailer,...



Or,...   3rd brake lights on my pickup,....



I've since that picture built a new mount. so they're center mounted, pointin' outward...
