  2. Active solar heating is using energy from the sun that is gathered by collectors and used to heat a building. • More than 1million homes use active solar energy to heat there homes. • It starts out with a solar collector mounted on the roof which captures the sun energy, then a liquid is heated, it is then pumped through a heat exchanger which heats water for the building.
