It is a shame that John Maddock from Tasmania does not come to this side as he has got an amazing set up

Why would it be a bomb?

Water,pressure, steam etc.and how incorporated into existing system?
Maybe heat exchanger is it?
Is it an open vented with cold water header or sealed system with an expansion vessel in system?
Do you get much down draught smoke with short chimney close to your house?
Ash nightmare to clean out ,if door was bigger you could slide a cut down/altered,bucket in maybe?
Looking good for your time and few hundred quid is it?

Water,pressure, steam etc.and how incorporated into existing system? plenty of relief valves if it ever gets that hot which it doesn't
Maybe heat exchanger is it? no
Is it an open vented with cold water header or sealed system with an expansion vessel in system? yes
Do you get much down draught smoke with short chimney close to your house? no
Ash nightmare to clean out ,if door was bigger you could slide a cut down/altered,bucket in maybe? its easy enough to remove with a shovel
Looking good for your time and few hundred quid is it? yes

G'day Ex. I do look in every few days, keeping tabs on you! and chanced upon your old post. You are much too kind, using a word like "amazing" - though I grant my heating system is a bit unusual, being custom built to retrofit a passive solar house design which lacks somewhat when the sun don't shine!
Essentially, I was able to make use of mostly scrap to build a wood burner under the suspended slab part of the house with the firebox door outside the building to stop smoke & ash being inside. It's a north/south firebox with an insulated outer door sheeted on the inside with polished stainless steel.
The firebox has removable baffles at the top to force the combustion gases to follow a longer path before reaching the flue. Some claim this allows better combustion, but I think it simply slows down their travel so more heat can be extracted.
The firebox has a serpentine of copper pipe at the back, and 3 turns of copper pipe around the base of the flue inside the white insulation (which is a super insulating ceramic, not asbestos). There is a 20m long run of insulated pipe to the flat plate solar water heater on the roof. As I write, the temperate is at 52C when the outside temperature is about 6C. I'm happy with that!
