I would think that it's the ambient air temperature that affects how much condensate you collect, together with how much fuel was burned. After the initial warm-up that gets you to steady state, wouldn't the efficiency be constant? If the acidity is a problem, you can run the condensate over a bed of acid neutralizing rocks before it goes down your main drain. It's a thing.

@3nibble Diode is bad. You can shorting it. But then you can power this Arduino only from USB or from +5V in the same time!!! Not both !!! This can damage your USB port.
