Default Room to Room Heat Transfer - Wood stove

Looking for some diy advice on installing ducting above the ceiling in my home to pull the heat from one room and dispersing it to three other rooms in the house.
I have an 1800 sf house in the Northwest, L shaped, with a wood stove in the farthest part of the house, basically at the end of the L. House is single story built in 1980 with base board heating and now has a wood stove. I don't like the base board heat and would rather burn wood as its free for me. I am wanting to move the heat without putting a fan in the doorway, as it doesn't distribute evenly to the rest of the house. The room with the wood stove gets really hot and the fan isn't what I'm looking for and its in a bad location.
I suspect there may be some code issues, not sure. I am wanting to know if this idea is efficient with an inline fan controlled with a switch or timer and insulated flex ducting. I would like to split off twice going to two bedrooms and then to the living room or kitchen which is at the other end of the house from the woodstove. I don't know where the best placement for the registers would be. Do I need to have return air grilles? What size ducting, fan cfm, where to buy materials?
This is the first time I have posted. I've owned the home for two years and just wanting to make some improvements and stay cost efficient. I'm also not really wanting to go with a furnace due to the costs of installation and the increase in utility bills. Any advice?

You could use insulated ducting and a fan behind the heater to blow the heat across the L to spread the heat around. Take the hot air from the ceiling of the heated room and direct it to the floor of the other rooms. You should have a fresh air inlet below the front of the stove (or wherever the stove pulls air in), that way you lessen the CO poisoning potential (which would negate the "cheap" of the free wood)

If you was to get a old furnace or blower out of one and put it in the attic.
cut a large register in the ceiling right above the wood stove, then you could duct from the register to the blower box or furnace and then duct from furnace to the rooms rooms like you want to. I have done this for customers
and it works fine. You could have a thermostat turn the blower on and off as needed. If you do decide to do this, let me know and we can get into it deeper for sizing ducts. Later Paul

Thanks for the advice. I am wondering if this idea of installing a fan and ducting in the ceiling is the best move. If I plan to sell the house, will this be considered an improvement or should I consider installing a furnace for a primary/secondary heat source? I want to think I am at somewhat of an advantage because I don't have a furnace in the house which gives me the opportunity to look into some newer/Green energy saving heating options. Unfortunately I am restricted to propane as the county has not brought in Natural Gas as of yet.
I have also contemplated radiant heat and infrared heat panels placed in different rooms.
I want to make the best choice with regards to staying low cost and efficiency.

People look at this in different ways. I am a heating contractor so if i buy a house i would want a 95 percent furnace with air on it. Now if i wanted to burn that wood i would put a coil in my hot air plenum which would be tied
into a outdoor wood heater. That way i could use it when i want, and still have a good heating system with air on it. That way i would not have the mess and the smell in the house. But this is only my opinion. Later Paul

Baseboard heating is probably the second best form of heating you can get.
Under floor heating is probably the best.
Water is the best conductor of heat you can get, its 4000 times better at delivering heat than air.
I suggest that you capture the heat from the wood stove and transfer it into the baseboard heating system.

what method did you have in mind for doing the heat transfer. Paul

I had a similar problem, I heat with Oil, Hotwater baseboard. Oil is outrageous. My secondary heat is Coal. I started using coal in 1980. I installed metal ducting and used an old squirrel cage blower with a snap disk on the stove. The snap disk is sensitive to the temperature change and you can get a range of on/off temps. Good luck.

I saw some info about the Shaver Outdoor Wood Furnace which uses the water to heat transfer and heat the house or also a waterless system with air. I would like to know more about how I can use my existing wood stove to transfer the heat to water and then to my base board heaters or possibly have to replace with a system to handle the heat transfer system. I will have to look up this info on the snap disk system as mentioned above.

I think you guys need to know the difference between a wood stove and a wood burning furnace . A stove is made to be free standing in your room with no ducts added to it or water coils. A wood burning furnace is made to add duct work and water coils to it. Later Paul
