Anyone know anything about these, or the technology employed ? I dunno, but
it feels like one of those "If it seems too good to be true ... " things. Or
is it just another company jumping on the eco-bollox bandwagon ?

This was discussed here a whiles back. It is called "co-generation" or
"combined heat and power" and has been used industrially for a century
at least.
An internal combustion engine drives a generator.
Heat from exhaust gases is used to heat the home.

So they chuck out your gas boiler and substitue a device that makes
both heat and electricity. Your combi- boiler is obsolete.
Simples. In theory.
There are massive operational problems inherent in these devices to do
with ratio of heat and electricity generated.
The cunning trick is to minaturise it and make it run silently and
reliably.
There are massive control problems too.

Perhaps they have been solved, the idea has been in extent for years
but the practical difficultiies in the domestic situation have stopped
it
