Um! Having hauled peat for my other grandma (in Scotland) in my youth - you have to stack it and allow it to dry before you can burn it.  And when you do that then in the winter, even in an open fire, it can provide a soft glowing heat that did not burn that fast. Peat and lignite have the problem of both high water and also high ash contents that must be considered when they are used as a fuel source.
Peat burns way way better in an air-tight stove than in an open fireplace. But your are right: The labor is intensive (and not fun), and you do need to dry it. But you need to season wood too, for at least a year, before you burn it.
