Megame, That is a good looking chimney ,looks like they did a good job and it kinda finishes the house... Nice.
I have noticed up in Ohio since we have family up there, Quite a few people are using the Hardy stove outside unit that utilizes an outside boiler type arrangement for hot water supplement and a radiator in the plenum with a separate thermostat ... I saw the works and it looked neat to me ,also it only needed feed once or twice a day depending on how cold it is.
I guess there are draw backs to both types, at least here my thoughts.
On your system its easy and conveinent to load in the warmth of your house,but you have to carry the wood inside with the mess of the chips etc. plus occasional clean-out...
On the outside unit the mess is outside but so is the heater(BRRRR!!!) when its 10* and it needs fed that wouldn't be much fun and you know who would have to feed it , SOOO you probably did the right thing,no doubt... /forums/images/graemlins/wink.gif
Obviously you did the right thing for yourself, But I wonder if you even considered the outside unit. I'm kinda doing a little research for the future as I won't be able to retire in Md. Too $$$ down here. With family in OHIO we might try to move up there one day... /forums/images/graemlins/laugh.gif
