1st time poster with wood stove question

Hello.  It's my first post on permies and I hope someone can relate to it.  It's an odd one.  
 
I'd like to add a wood stove to my house.  I have other heat sources going on, but the kitchen and master bathroom are the issue.  They both have tile floors and are on a northwest exterior wall and they radiate cold air.  These two rooms have a laundry room in between them, which I don't need to heat but it's the perfect spot for this stove.  The door of the laundry room opens to the kitchen but there's a wall that separates the laundry room from the master bathroom.  

My question is, what are some effective ways at getting heat through the wall?  

Hello John!  

Welcome to the forum!

It sounds like you could build a rocket mass heater.

In this video there is a heater you might be able to use to put heat on both sides of a wall.



In this movie there are many examples of rocket mass heaters installed in a variety of locations.  I think this is one of the best movies to help you decide what to build in a specific space.

Once you decide what you want to build you can get the specific plans for any of these designs.

Thanks for your reply Samantha. Those mass heaters are very interesting but I don't think something like that will work in my situation though.
The laundry room is 11' x 7' with a washer, dryer, hot water heater and shelves full of various kitchen gadgets. The old hvac unit takes up a bunch of room but I will be removing it and that spot is where the stove will go. A smaller stove should fit.
I'm looking at a 1,200 sq ft unit made by Vogelzang. It's $700 minus the expensive part, the pipe. I'm thinking a vent as close to the ceiling as possible with a fan in it? I could install a long vent on either side of the wall with a fan in between them. Maybe even 2 or 3 of these vents? This bathroom is the furthest from the fireplace and I considered a tiny house type of stove in the bathroom but the kitchen would still need something.
I've got a couple arctic mini heat pumps which heat really well and a stratford 2 fireplace which I consider the main source of heat but those mini's gobble up my solar batteries power at night. With a consistent source of heat on the opposite side of the house, those mini's will not be needed nearly as much and I might not have to add more batteries and complexity to my solar system.

Welcome to permies, John!

Given what you describe, I'd go with cutting holes in the wall, one high and one low, with an inline fan in the low hole to blow the cold air towards the stove.  
Something like this should work well and not draw too much juice:

Ideally, I'd put the stove in the basement, but I'm guessing either you don't have one or it's not an option.

Hi John;
Welcome to Permies!
I recommend checking out the Liberator stove.   https://rocketheater.com/
UL listed it can burn wood or pellets,  
It is a rocket design stove, and indeed, if you had more room, it could support a mass.

Thank you for the reply Thomas.
That stove is made in MO which is where I am but it's not the type of heater I'm really concerned with. How to get the heat from the laundry room into the bathroom is what I'm trying to figure out.
The laundry room is in the middle between the kitchen to the left and the master bathroom to the right.
The laundry room door can be left open to add heat to the kitchen but to get heat into the master bathroom, I'll have to go through the wall.

Thank you for the reply Pete.
I think you're right. The hole on the bottom might be tough because there's a large jetted tub and a vanity, back to back, on the other side of that wall. I could go through the vanities baseboard with a rectangular vent and then use 2 or 3 smaller square fans.
I've read that one should blow cold air towards the stove, not the hot air away from the stove. I suppose I could try this without the fans first and see if convection is enough.

Something like this would work. it would be nice to find one where the vent closes but they've got those magnetic vent covers that might do the trick.
