I'll let the manufacturers answer, if they wish. But the main annual cost
is in fuel - not hardware. High efficiency can count for a lot. These
probably have guarantees for much longer life than the traditional - that also
needs to be factored in. There is also a "pride of ownership" factor. Also
time savings have a time value.
If char is produced, a cost like this can be recouped in well less than a
year.
This is a very complicated topic - and these manufacturers seem very
competent to not go down a path sure of failure. I was surprised at the high
quality look for the price.
There will be demos on Thursday and I'll try to catch reaction to all stoves
shown.
