This one I personally don't know. What I did turn this little fiasco into though was a test of rubber tree farms for methane production (gregtech) and a single rubber tree farm can produce enough rubber wood to supply two centrifuges with a little to spare, and at max temperature it should only take 1.25 centrifuges per boiler to keep them running (or 5 centrifges per 4 36hp boilers). I haven't managed to get the boiler to max temp yet since I just started, so I can't be 100% sure yet, but that's going by figures someone else mentioned. It is kinda sad that it eats a ton of fuel to start off, so what I might end up doing is if I need more than one boiler I'll fill a RC tank (not gonna use the quantum tanks, they feel a bit too easy and don't look as good imho) with methane and jump start my second boiler using some BC fuel until it gets hot enough to not guzzle down a bucket every 10 seconds.
