What is convection
The transfer of heat by the movement of one part of a fluid to another.
the transfer of heat through the collision of particles
the transfer of heat through waves
What is conduction?
the transfer of heat through waves
the transfer of heat through the collision of particles

What is electric heat?
Uses convection to heat
Uses radiation from the sun to heat
Turns electricity into heat
What is hot water heaters?
Sends hot water throughout the house and that creates a convection current
Uses electricity to heat
Uses radiation to heat from the hot water
Forced air heat
Uses the conduction from the air ton heat
Sends hot air through the house using fans
Uses the convection current of the air outside then it pulls the heat out there inside and sends it trough the house.
Heat pumps...
Converts electricity to heat.
Grabs heat from outside and brings it inside.
It just generates heat from nothing!
Solar heating uses...
Solar panels to capture the sunlight then turn it into heat.
something...
A mix of electric heat and heat pumps
