Royall, I am thinking maybe a simple batch heater to preheat the water from the catchment and then into a gas or electric 30 or 40 gal. standard water heater might be the most economical way to go. There are lots more ways to go for more dollars but I wonder if they are really worth all the bucks. A search on Google for batch water heater will bring up lots of ideas for you.
