Energy Efficiency Services Limited
Most households in India are cooled by fans, and less than 10% of households have air conditioning. The average rating of the fans installed and sold in the market is between 75-80W, whereas energy efficient fans provide the same level of comfort at about 45-50W. Considering that almost 30 million fans are sold every year, the potential to reduce demand is significant. Replacing the country's 35 crore inefficient ceiling fans in with BEE 5-Star-rated ceiling fans could save 47 billion KWh and reduce load by over 12,250 MW.
Air source heat pumps
All-electric heat pump systems have an electric furnace or electric resistance heat, or strip heat, which typically consists of rows of electric coils that heat up. A fan blows over the heated coils and circulates warm air throughout the home. This serves as an adequate heating source, but as temperatures go down, electricity costs rise. Electrical service outages pose the same threat as to central forced-air systems and pump-based boilers, but woodstoves and non-electric fireplace inserts can mitigate this risk. Some ASHPs can be coupled to solar panels as primary energy source, with a conventional electric grid as backup source.
