Heater Is neither Conduction nor Convection... The Questions seems to be wrong... If you ask Whether the heat given by a heater is lost by conduction or Convection, then the answer is: YES! In a heater the heat is lost by all three processes namely Conduction , Convection and Radiation.
Convection primarily.
Historically, a heat source, whether in a fireplace or a furnace, heated the air in a home and set up convection currents because the warm air was more buoyant. Modern homes use a "forced air" system to transfer heat which most people also consider convection. Heat transfer through conduction and radiative heating are sometimes important too. Obviously, the objects in a house acquire heat from the air and warm through conduction. Radiative heating is perhaps most obvious with a fireplace where radiative heating occurs in addition to convection.
Heat loss from the home has both conduction and convection processes at work. The reason one puts insulation in a wall or ceiling is to reduce convection.
Hair dryers use heating element and motor-driven fan to convert electric energy into convective heat.

The metal pole rapidly 'CONDUCTS' heat away from your tongue.
The first: conduction from the solid heating coil

conduction by itself is slower to heat but conduction and convection is faster to heat
Convection has a cycle of what happens. Conduction dosent have a cycle

Lack of a flow medium will inhibit conduction and convection.
