Wl110 Dump Zone

i tied my primary circulator in as the dump zone. I've done this in the past with indoor wood boilers for customers dump zones with good success, but their boilers had quite a bit more water capacity than this Lil boiler at 12 gallons. It seems to work good so far anyone out there in coal land see a problem with this??
She dropslike twenty degrees within one minute, and it's warm out rightnow, I figure it's ok.?.

btw her name is "Sugar", cause she so sweet!

As long as you never insulate your primary loop, and it is working to dump sufficient heat at present, I can't see anything wrong with it. I prefer a zone to be used as my dump, and for me it is my basement zone loop that doubles as my dump loop.

I would suspect that running normal you will need more heat rejection than your primary loop. Remember, when you dump loop is needed the primary circuit will most likely be saturated (hot), there fore a need for more heat rejection.

The issue is when the boiler is running all out and demand drops to zero, coal is a bit like a train and the momentum will last for a bit.

A simple fix is putting in 2 slant fin 30's 8' long from home depot. you can get about 11,000 btu/hr @ 200 degree water in. This is roughly 10% of the boiler capacity and works great.

just my thoughts...

I thought the same, since primary circulator comes on with zone circulators, my fix is a floor mount hydronic heater that was removed from a refurb job, it was mounted under a window in a nursing home, I actually have the fan motor cycling with a zone valve in event of a dump. works like a charm.
Thanks for all the input
