hi!
first time post..
looking to install a second wood stove in Southern CT , heating this 2500 sq feet is not cutting it I have a RSF stove that i have tapped into the air handler of the house, heats upstairs pretty well when it gets going, but downstairs has no heat. looking to install a second wood stove in the cellar, taking the flue pipe out an unused casement window.. wondering if i could design a portable "thermal battery" of sorts, by building a box out of wonderboard, snaking 6 inch flue pipe through it and covering with cob... bad idea?

John Marcinauskis : Hi! Welcome to Permies.com, our sister site, Richsoil.com, and The Rocket, Wood stove, and Cob forum threads! With 29,000+
Fellow Members worldwide you should be able to come here 24 / 7 and find someone who wants to talk about what you want to talk about !

1st ! You have a very unusual working set-up that is probably not reproducible, and I don't think you want to ! Unless you have an unusual house layout with a very
open plan and a huge open stair case going upstairs, Then the culprit for all your heat going up stairs is Your Air Handler - or a combination !

You should have dampers inline within the ductwork that can be gradually closed off or find a way to reduce the size of your registers to reduce warm air flow!

A sketch of Your houses layout might help, pictures of the area going upstairs will help definitely !

So- Just because you now have a set-up that pulls the heat from the 1st floor to the second Floor, does not automatically mean that any heater placed in the basement
will give up its heat to the 1st floor !

Please take the time to google ''Stack Effect'' and ''Whole House Stack Effect'', not only are you going to be fighting the upstairs wood stove and the air handler, such
mundane household practices as running a cloths drier vented out doors, or the fan in the Rangehood over your kitchen stove, or running the bathroom exhaust fan
vented outdoors during a long shower can cause the Wood stove in your basement to smoke back, with a wood stove located in such a remote location, out of sight,
out of mind, your Basement can fill up with smoke before you know you have a problem !

You seem to be flirting with the idea of a Rocket Mass Heater RMH, or at least the thermal battery. The RMH or a Massive Masonry Heater costing 10s of thousands to
install will store that heat for you. However, the RMH is if any thing slightly more sensitive to these air handling issues than a regular wood stove, especially when installed
in a remote below grade location !

Perhaps someone with experience with using multiple heating sources and Air handling equipment too can add something more positive ! In the meantime please do that
Google Search !

For the Good of the Crafts ! Big AL

Do you have someplace inside to make a flue stack?. If you box in an air return from the peak of the house to the basement an install a fan to pull the heat down, you will help rebalance the temps. Or get the air handler re tuned. Your stove should put out enough heat unless your house is poorly insulated, and then you should spend the money sealing up the house before buying a new stove.
