It's been tried and it doesn't work because hardware designed for crypto mining needs to be utilized 100% 24/7 or it won't ever pay back or be meaningful, and it that case you either size it to be such a small heat contribution that you don't mind a small heater on during the hot months, or so big that it is impossible to offset in the summer.

Nevermind the fact that resistive electric heat in this day and age is wildly stupid except for maybe the northernmost parts of Siberia. Why pay X to get A heat plus almost no bitcoin, when you could pay X to get 3A heat using a heat pump?
