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

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.

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.
