Maybe a heating element in the rain gutters? I'm not a fan of wasting electricity, but that may be worth the extra water.

This tank installation requires that there is no hindrance from gutter to tank. Normally one would put a "sand catching" vertical tube, where the sand and other heavy particles would fall to the bottom. I think in this case, they don't want the idling water to sit there and catch bacteria? Or maybe the flow or ...
In any case, I have thought of some kind of filter in the gutter - I just need to make sure I remember to clean it now and then.
As for the tank - pollen floats to the top, sand goes to the bottom, so as long as the water is taken from just below the surface, I should not need to clean the tank that often.
I think the electric gutters will be too expensive. With falls usually being quite wet, I would imagine I would have close to a full 7500 liters / 2000 USG approaching december, so the period of no water should be short - if any. In normal winters here, there are usually periods with thawing - only recently was a bit odd, with several consecutive months of no positive temperatures at all.
