In my area cold water inlet temperatures often drop to almost the
freezing point of water. I have recorded temperatures as low as 34F
in January when the frost get down to about four feet below ground.
The average temperature in my basement where the water heater and
furnace sit remains about 66f all year. I had though of putting in a
second bare tank to receive the cold water before the water heater,
allowing it to heat up to room temperature before entering the water
heater. Any thoughts?

You'll pull heat out of the air to warm the water in your tank from 30's
to 60's.

To some extent, you'll be using your space heating system to assist the
water heater.

 Too an extent, that's true.  If you cool the basement much, it will cost
more to heat the house.  That said, it won't cool the basement a great deal.
 But instead of a tank, I'd use a coil of copper tubing.  Place 2x4's
between each coil, in line with other, to keep them separated.  Vertical
would need a stabilizer

I would consider installing a copper 'vertical ground loop' a few feet
below the frost line to push heat into the water more directly.

Something like:

I would heavily insulate the tubing that was above
the frost line.

I figure that a bare tank in the basement would have too poor
a coupling to the temperature of the soil to do you much good.
If your water heater is located in the basement, lowering the
ambient temperature (with the bare tank) would make the
water heater run longer.



Don't *faff*, dear.

The frost line here is four to six feet, below that level is limestone
;~) basement is unheated and remains at 66f year round, which is why I
thought there would be negligible heat loss with a 40 gallon tank of 34f
