When light is absorbed by surface, the material temperature increases and remits light at a longer wave, ussually in the IR spectrum. So its safe to say all light is heat enegry.
But a heater produces heat and light. The light might turn into heat later but that’s not heat from the heater. Otherwise everything is s heater and it’s all part of the same heater… the universe.
Isn’t some energy still dissipated as light instead of heat?

Which travels to a location, hits it and is eventually converted to heat.
So not a heater…but the universe.
Typically a heater is in a room, so any light doesn’t need to go further than the nearby walls
