Some of the issues are: the noise from the fans, you have to move the heat out of the miner. Miners are computers, they fail in more ways and more often than a space heater does. If you are heating only with miners how do you regulate the heat, by slowing the miner which makes it earn less and is less efficient?
In essence you can easily heat your space with electronics without using crypto miners. Just turn on all your gadgets and lights in the winter and leave them on. It's very convenient to have them on all the time, and the normal heating system will fill in with extra heat to regulate the overall temperature. It may even help your electronics last longer since turning them on/off tends to be what eventually destroys them (at least that was true of electronics 30 years ago, not sure if it's still true today.)
