In Maine I have seen people set a big coil of 1 inch copper water pipe next to their wood stove and plumb that piping in series with the regular hot water heater.

As long as the wood stove is going the hot water heater almost never comes on.

It as simple as anything you could hope for and works almost as good as anything you could buy.
