Convection
conduction
Convection. The hot water at the bottom of the pot rises to the top.
Conduction
what pan? if you are talking about on a stove its because the element on the stove gets hot when you turn it on and the heat gets transferred from the element onto the pan.
The heat from the stove makes hot water because like the food when you use the stove it makes it hot to. right?
Wood stove when used gets hot and stays hot for a very long time, making it dangerous to have around children, whereas a pellet stove don't get too hot to touch.
As the stove heats up the pot, heat is transferred from the pot to the water through conduction. Within the pot, heat is transferred through convection from the hot water molecules to the cold ones.
obviously you'll get burned if you touch the stove while its hot.
a stove top is attached to the top of the oven.. the heat goes through. therefore it gets hot.
Stove top kettles are primarily used to heat water for tea or hot chocolate. An electric kettle works the same way however the risk of shock is a constant threat because water and electricity do not work well together.
Boil it in a pot on a stove.
You can not answer that question without knowing more about the size of the hot water heater, the size of the stove and oven combo. How often the stove/oven is used, and how much hot water is heated. Water temp. is a factor as well.
A stove is a two pole 50, and hot water heater i would recommend the same.
