Well, I decided to upsize my new Heritage to an even newer Mansfield. I thought I'd be able to get enough heat out of the Heritage for my place, but with the high ceilings and approximately 2000 sq/ft, my main floor is just too much for the Heritage. I was working the stove way too hard to keep my main floor at 70*F on colder nights and I haven't even seen below zero temperatures yet. I didn't want to give up the side door, but I needed the extra heat output, so my hearth now has a Mansfield sitting on it.
First impressions:
* Obviously it's bigger. Mostly depth is the difference... it's about 6" deeper.
* Secondary tubes and and baffle. The Mansfield is significantly different than the Heritage. The Heritage has a cast iron manifold with 3 tubes. The Mansfield has a steel manifold and 4 tubes.
* Two air risers going up to the secondaries on the Mansfield instead of one on the Heritage.
* Much less cast iron in the firebox. The Heritage, with its side door one side and a cast plate on the other has a bunch of cast iron in the box. The Mansfield looks much cleaner with just stone.
* Primary air control linkage is different... just a bar attached to the control lever that directly slides a pair of plates on either side of the firebox. I don't see how somebody can do an OAK with it.
* Has a much larger ash lip in front and a more sharply angled shelf in lower front of the firebox for containing ashes.
I've done my 3 break-in fires, so I'll be cranking it up tonight. I'll report back with how it performs. So far, it appears that the Mansfield's primary air into the firebox is quite a bit stronger than that of the Heritage. This could be due to the fact that I had the Heritage rear-vented and the Mansfield is top-vent only. I had to use two 90* elbows. Didn't want to do that, but that's the only way it would fit. Draft seems great, though. I get a pretty good blow-torch affect on wood right in front of the air ports when the primary air is wide open and shutting the primary controls air input very well. The break-in fires burned fine - no smoke and nice even burns.
I'm eager to feel the difference in heat output.
