We had such an arrangement in our last house in Colorado Springs. The kitchen was above the utility room in the basement. The line from the hot water tank was insulated and then at the kitchen faucet a tee enabled another copper line to go back to the hot water heater's drain valve (which had been removed and a tee inserted to allow both the drain valve and the returning copper line). The heat loss from the bare copper return pipe slightly cooled down the water in it making its density slightly greater than the water in the insulated supply pipe, thus causing the thermally-induced circulation.
