The heat source for a toaster is typically electrical coils made of nichrome wire. When electricity passes through these coils, they heat up and generate the heat needed to toast the bread.
Input energy: usually electric energy. Output energy: heat.
A toaster uses primarily conduction and radiation to cook food. Conduction occurs when the heating elements directly heat the bread touching them, while radiation happens when the heat is emitted to cook the outer surface.
Energy can be transferred efficiently from a heat source by using materials that are good conductors of heat, minimizing heat loss through insulation, and ensuring a good contact between the heat source and the object receiving the heat.
When a heat source loses energy, the energy is transferred to the surroundings in the form of heat.
The three common sources of heat for heat pumps are air, water, and ground. Air-source heat pumps absorb heat from the outdoor air, water-source heat pumps extract heat from water sources such as rivers or lakes, and ground-source heat pumps use the stable temperature of the ground to provide heating.

Heat does, indeed, go from a warm source to a cold place. That is what heat always does.
A heat wave is a source of thermal energy.
The main source of energy and heat is the sun.
