However, fire actually is very useful during certain treatments. For example, if someone is bleeding badly, you can melt a sugar coating on it to stop the wound from bleeding further. Also, the sugar has an antibacterial effect. In a primitive hospital like they have at the Colony (or the rest of the world in We're Alive, for that matter), I could imagine such treatments being used.
There are many more treatments requiring fire or extreme heat that you wouldn't think of first, but are actually very practical if you give it some thought.

So basically, while I think your theory is pretty likely to be true, there is a chance she was telling the truth.
Hell, if nothing else just remember cauterizing Saul's gunshot wound. If someone wasn't holding down the patient well enough for Tanya, you could pick up a nasty burn super quick.

Besides, maiming wouldn't help their purpose of pulling your own weight. I feel like the punishments are enough to get your attention (see: Taser), or you are just killed (broken nose=broken neck). If you hurt someone enough, they wouldn't be able to to enough and therefore, must be killed. So, cut out the middle part and just kill 'em.
