Seems as though there ought to be low temp thermostats, so
the room stays over 35f. Ask at your nearby hardware store,
see what they have.

More work, you could tap the far end of the hot line (far
bath room for example). Put in a small circulator pump. Take
hot from the far end of the system, and pump it into the
cold supply of the WH.

Less work than that, you can foam wrap the hot line. Leave a
hot faucet dripping at the farthest part of the house. That
will pull a bit of hot water into the pipe.

A timer is a very good idea. I was trying to think of
something that
would only come on when the temp gets to 32. A timer seems
like the
next best thing.

The WH is in her laundry room. It is part of the garage and
no
insulation.
