Questions

What is the best heater miner?

For a medium room, the Avalon Mini 3 (about 800 W). For a bigger room, the Heatbit Maxi or Trio (up to 1,500 W). The Avalon Q gives the most heat but suits a garage or basement.

Does a heater miner heat as well as a space heater?

Yes, watt for watt. Nearly all the electricity becomes heat, just like an electric heater.

Will it pay my heating bill?

Part of it at best, and nothing is guaranteed. In a pool it earns small amounts that offset some of the power cost.
