The Independent has it wrong, CRW do not make a boiler,they make the fuel cell that might end up in somebody elses boiler design.
CFU makes the whole kit, from fuel cell to the final boiler.
They have just recently signed an agreement with a German and French energy company to evaluate their latest designed boiler, to hopefully bring it into commercial sales sooner rather than later.
They are also proposing to build a powder factory in the UK in the near future.
So personally on balance I think that CFU are futher down the road to commercial sales.
DYOR.
Cheers.
