Fan system with water-jacketed stove

[Lerhuset]

Hello! I live in an older house with 4 rooms and two hallways with doors in between. That is, not an open floor plan. Approximately 120-130 sqm, 270-300 cm ceilings, and rooms about 25 sqm. Root cellar under the house (cold floors). Thick walls about 60 cm, consisting of clay, straw, and lime. Currently, we heat the house with electricity, a cast iron stove in the kitchen, and a tiled stove in one of the rooms.

We are now approaching retirement and are considering installing a water-jacketed stove, running a pipe up to the cold attic with a heat exchanger with a thermostat, and running spiral pipes down to the rooms. This is to reduce the cost of electricity, wood, and achieve a more even distribution of heat.

We would like some input on the advantages and disadvantages of the system.

Spiral ducts??? Radiators in each room and a storage tank so it can be fired properly.

The idea of having a heat exchanger from a stove is probably not good, it's a form of hot water system and then the water must be at least 75 C to output any heat to the air. And it has to be a really large exchanger, a small one won't work. So the question then becomes whether it's economical to install. If you don't already have a waterborne system, I'm thinking of the wood/electric, maybe there's some form of fireplace in the house.

Having a heat exchanger from a stove might not be a good idea, it's a form of hot water system and the water must be at least 75 C to get any heat to the air. Moreover, it needs to be a really large exchanger, a small one won't work. So the question becomes whether it's economical to install. If you don't have waterborne heating already, I'm thinking of that wood/electric option, maybe there's some form of fireplace in the house.

Chimney with its own flue down to the 4 large rooms. That means you can have a fire in all rooms, but today we only use the old masonry stove in the living room (with doors like a tiled stove) and the large cast iron stove in the kitchen. 2 rooms are left cold during winter. It has become extremely expensive to heat the whole house with electricity, and it requires a lot of work with firewood to reduce electricity costs. We thought we could make it easier for ourselves as we get older by firing in one place and not in four, and still get heat throughout the whole house. Today it doesn't work because we are working. We can probably build and do most of it ourselves except for the electrical work where certification is needed.
We gratefully welcome other suggestions that might work if the above with a heat exchanger does not work. It feels a bit cumbersome to install a waterborne system, and that cost would also be significant.
