Question

A hydronic heating system uses ______ to move heat around in the system?

1) convection
2) radiation
3) conduction
4) evaporation

Answer 1

A hydronic heating system uses convection to move heat around in the system.

Step-by-step explanation:

A hydronic heating system uses convection to move heat around in the system. Convection is the transfer of heat by the macroscopic movement of a fluid. In a hydronic heating system, hot water or steam is circulated through pipes to radiators or other heat exchangers, where it releases heat to the surrounding air.
