its actually a thermostatic valve.  it controls your return water temps, when return water temps drop below 140 it bleeds in some hot water from the supply side keeping the return temps from becoming low enough to cause damage to your boiler. 

cold return temps can casuse the moisture from the wood gather on cool spots on the firebox and run down into the ashes leading to early death.    its an effort to prevent that, some companies require that now

This seam to take some design features from the ml25 they came out with a couple years ago.  Wonder how much better it burns, did they square the bottom of the firebox and line it, or is it just a lined ml30 with a new outer shell, hard to tell from the pictures.

bottom and 12 inches up sides is lined with firebrick....looks like a rounded bottom but still has ash pan....i was trrying to figure out if it has water all the way around it or if it's like my thermal-control that does not have any water under firebox....

Wondering the same thing about the water and if something like this could be applied to an ml30 without harming it.  Would be nice if a little refratory material could make a cleaner fire.  Although reading it again it says the top water jacket in flanged to the  bottom refractory brick for easy dissassembly.
