Wind heating system is an efficient and available system. System -1 / -2 could produce carolic value nearly 5000Kcal / 10000Kcal daily in months of average wind speed of 6 m/s, say, to heat water of 100 / 200 litres raising temperature about fifty degrees centigrade and mitigate CO2 over 10KG / 20KG daily.
Wind heating system is an economy system. The system cost is lower much than battery-charging system and wind grid-tied system with comparative output.
