While you're at it, you can track down the circuits that are causing the problems by pulling the fuses, one-by-one, and seeing if the current drain decreases.
Barring an electrical gremlin, it's got to be alarm and/or journey length.
My bike sits outside all the time, no chance of using an Optimate. It does get ridden regularly but occasionally it does stand for a week (maximum has been a fortnight one particulalrly nasty Winter).
But it is very rare for a ride to be less than 20 miles and I've never had an alarm. I've never had a battery problem (famous last words ). That I can recall anyway though my 1150GS started getting a bit tired after 4 years.
bike has been fine since new battery fitted, I do work odd shifts so a solar powered trickle charger may be the way to go,as garage is in a block with a flat roof and nice air bricks i can feed wires into.
Must say the GS is the most comfortable bike I have ever ridden I just want to ride further and longer and even thought its winterish I find excuses to take the bike.
"....Why are all bikes not fitted with heated grips...?" i would say that they are simply not required in some areas; I did not specify them on my previous GS (but as here they were only 200€ extra I think that was an oversight.) however I cannot remember more than the odd occasion when I would have used them -and I ride all the year round. My 2008 model came with a package that included the heated grips. I have tested them but not needed them yet!

Another tip to help the battery is to pull the clutch in when starting. Saves the starter motor having to drag the gearbox around as well as the engine. Consequently less current taken from the battery.
