I had no trouble in St. Thomas, ON, getting it to bubble on the coldest
days. You _will_ need spare diaphragms for the pump though. They don't
hold up well to major cold and I would go through two in a winter.

Thanks Derek.

I'm really noticing the reduced output even at these temps and I'd like to
avoid the new diaphragms.

So I built my 12W container (Cashew jar) out of some junk in the electronics
box. So far it's keeping the box 30° C above ambient. But, once the pump
starts sucking cold air into the box? I think the 12W will be overwhelmed.
Perhaps a heated sock is the way to go. More testing required.
