What were the first 3 heat machines? Main differences? What are today's equivalents?

A steam turbine was invented by by Taqi al-Din in 1551.
The first practical steam-powered 'engine' was a water pump, developed in 1698 by Thomas Savery.

I would think that the first mechanical device for the purpose of creating heat must have been the bellows. Ovens would have been created earlier, but they are not mechanical. Right? Today's equivalent must be a bellows in a steel furnace
What about a piece of glass? If you focus it, you will create heat. Not really mechanical though.
A bow and a stick for making fire. That has to be a mechanical device that makes heat. That should be one of them. Today's equivalent has to be a match.
I wonder if a fan that was operated by pedals and was designed to transfer heat from a fire to the rest of the room would qualify. I remember reading about something like this in antiquity. Today's equivalent has to be a heat pump.
Guessing for the most part.
