The question doesn’t get much more detailed, but how does head vanish.
My understanding is that heat is a direct type of energy, and energy cannot be created or destroyed, only change type, but I get that, with a heater for example, electrical energy becomes heat energy, I don’t understand why the heat energy then becomes something else, or indeed what it becomes that isn’t heat, because cold isn’t a type of energy.

Generally speaking, heat doesn’t vanish. It spreads out and causes the temperature of the surroundings to increase. Since the amount of heat from a heater is small relative to the total surroundings, it is hard for any single heater to increase the temperature of a large area/volume significantly.
The energy is still there it is simply spread out to such an extent that measuring it is difficult.
An analogy would be say a swimming pool filled with water. You can add a glass of water to the swimming pool. That added water didn’t disappear but it would be difficult to measure any change in the water level of the swimming pool from a single glass of water. The water is analogous to heat energy and the level of the swimming pool is analogous to the temperature.
