Have you given ole Dormermike a price yet Dan? 
The Forum rules that forbid discussing gas related issues like this... if you want to discuss it we can in the Combustion Chamber.... Otherwise I ain't gonna be encouraging you do do this; sorry... I pay a lot of money to hold the certificates I hold...
If you want to know such things I politely (I mean that BTW) suggest you get the accreditation.
Like I said - you will waste several lifetimes worth of Pilot light gas costs trying to do what you want to do, and at the end of it you will have a more complicated boiler with increased chances of failure.
Ok dormermike lets see 'roughly' how much that pilot light is costing per year.![]()
0.25mm injector @ 22mb.
0.036 x 0.0625 x 0.95 x 5.87 = 0.013 m3/hour.
8,760 x 0.013 = 113 m3/year.
Pilot light usage would be around £30 a year , if your going through thermocouples by the dozen then expect around £60 a year.![]()

OK fair enough. Can't understand why you think my question jeopardises your certs though but appreciate your position.
