Conventional wood stove convertion to RMH

Good day to you, folks!
I've been browsing permies.com for a year now, and first of all, I want to thank this spectacular community!
Let all the best be with you!

This is my first post, so I'm really sorry if I ask something that was asked a thousand times already.
My English might sometimes sound bad, so have my pardon for that too

I have a conventional wood stove made of cast iron.
Last winter was my first with this stove, so I have a lot of claims to its efficiency.
Basically, RMH idea was on my mind long before I bought my stove, but due to time limitations and urgency I had to go the easy way so my big family would meet the cold times safe and warm.

The question is: can the conventional stove be somehow converted to RMH or can some kind of a hybrid be built?
I really want to raise its efficiency, cause, you know, it's not cheap to buy so much wood in my country.
I used around 15 m3 (cubic meters) for 6 months, and it's a disaster.

I'll be very happy if someone gives me a clue on where to look at, and what RMH-path to choose.

Have a nice day, everyone!

Filili:  The best mod for a conventional metal wood stove, I have ever heard of is called an intensifire from New Zealand.  Adds a down draft after burner in the fire box.

The test


Somewhere in the articles I remember seeing a 60% improvement listed.  If you need more then add a high mass brick stratification chamber next to the stove for overnight heat.

Tom,

thank you very much indeed for an answer!
I didn’t quite get the idea of how it works, i think i just can’t access all information on my phone. I mean, website you mentioned is not displaying correctly for me. I’ll dig into it from laptop.
I still have a few questions if you don’t mind:

1) What if I layer the inside of my fire chamber with talcomagnesite? Will it help to store heat for longer? I used to have a stove made of talcomagnesite and by burning just 10-12 logs in the morning it heated my previous house for 12 hours with the outside temp as low as -25 celsium, and the inside temp was in the range of 25-20 degrees for the whole day.
2) When you say “chamber”, do you mean that I can attach it directly to the body of my stove?
