Can you have conduction + convection at same time?

Can you have conduction and convection at the same time?

For example with a water heater, which takes in water and ejects it back out into a swimming pool, does it use both conduction (a heater) and convection (fluid movement)?

Thanks.

Anybody?

most likely the answer is no. conduction is due to a movement of temperature through solids and convection is through a non-solid medium such as air or water.

in your example of a pool heater, they are likely two separate processes. the heater itself may be generating heat internally by conduction, and then that heat that is produced is likely heating the water separately by convection.

hope that makes sense

Hmm..I am confused. So a water heater has coils that are heated. I assume that these heated coils that come into contact with the water heat the water through conduction. The water is then pumped out into the pool. The heated water will rise due to decreased density (this is called convection) and the cooler water will fall to the bottom of the pool where it will be heated by the coils. I recalled a practice question about conduction and convection in a water heater and whether it was either one of those or both.

I am also wondering the same thing, would anyone have the answer to this?
Since the heater and the water are in contact with one another, wouldn't you also have conduction?
Thanks.

conduction between the heater and water, then convection within the water? Isn't that the conclusion that has already been reached, AspiringDoc1?

Yes you can...think of a cup of steaming water

Heat is leaving into the air via convection and moving to the walls of the cup via conduction
