the best idea, but servicing could be a PITA.

2) Put an insulated box around the gate valve inside the filter room.

3) Wrap one of those electric heaters around pipe inside the filter room.

4) Put a better door on the filter room. Probably not cost effective.

Any thoughts on the least trouble free solution?

I see trouble free as being inside the filter room.... but, that leads me
to a question. I always hear things about valve eventual failure.... Does
this mean leaking, as all over the basement floor, or just the opening and
closing thereof? ~ jan

Not really the basement, but the external entryway (not used) to the
basement. It has a separate drain, which has been 'tested' during my
tunneling experiments.

I suppose two valves would be best, as it would let me service the inside
valve without draining the pond. But there would still be no easy way to get
at the outside valve for servicing.
