Porridge is made from oats where I live. Is it made from wheat flower where you live?

Not commonly, but you can make porridge out of many things, including almost any grain: https://en.wikipedia.org/wiki/Porridge#Varieties

Wheat flour's talents tend towards baking because of its high gluten content, so in a sense it's "wasted" on porridge. But if your oven isn't working it's less of a waste than literally throwing it away!
