We've had a rain barrel under one of our downspouts for years. In our city, it's important to manage rainwater which routinely floods our ancient combined sewer system and pollutes the river which pollutes the bay downstream. I use the rainwater to water our outside plants. In hot weather, the water gets a little smelly - haven't tried very hard to solve this problem in an eco-friendly way, so I want to know if you have solutions (and any other rain barrel management tips - you can see we are a no-frills operation).
I think most people in our area disconnect their rain barrels from their downspouts in freezing temps, but we have not. I do actually use rainwater through the winter on houseplants and with compost activities. It is important to keep the rain barrel from freezing as the ice can damage the barrel itself as well as the spigots and overflow spouts through expansion and thawing. On warmish days, I would try to remember to drain water as needed to keep the rain barrel at half full or less.
But I have hit on a more successful (for me) method: the stock tank heater. I don't love shopping as entertainment but it is true that sometimes shopping without a plan yields exciting problem solvers. I didn't even know there was such a thing as a heater for an animal's drinking water!

I just plug it in when the temperature is cold enough long enough to freeze the barrel. I do have to use an extension cord, which is not recommended, but our outlet is a new GFCI outlet so I am comfortable with the safety. The cord has a plastic sleeve to protect it from the top barrel edge as the heater floats along in the rain barrel.
After I bought this heater and had it going, my dad told me it's possible to buy stock tank heaters that are "temperature limited," meaning they run on a thermostat and only heat the water to a pre-set temperature. That seems like a prudent energy saver that I would look for next time.
I have now put away the stock tank heater three times this spring, mis-judging the depth of cold still in store for us. I am almost scared to put away the cold weather things again! Sadly, our neighbor's gorgeous magnolia buds were ruined in the last surprise cold spell, and I will miss the creamy pink blooms this spring.
