1. Celebrate #EarthDay https://abs.twimg.com/hashflags... draggable="false" alt=""> by making your own quiet, energy efficient #Bitcoin https://abs.twimg.com/hashflags... draggable="false" alt=""> space heater.

You need:
- @braiins_systems
- some @Noctua_at fans
- an older ASIC miner

2. 25-40% of your heating is lost in your ductwork.

Using a space heater reduces those losses by taking load off your central furnace.

3. 16.1 million homes in the US heat with a central electric furnace, and would see up to a 25-40% reduction in heating energy consumption by supplementing with space heaters.

4. A resistive heater, like a #Bitcoin https://abs.twimg.com/hashflags... draggable="false" alt=""> miner, is not as efficient as a heat pump.

Heat pumps can be 2-3 times as efficient, but are not an option for millions of renters.

5. You can reduce your energy consumption AND support #bitcoin https://abs.twimg.com/hashflags... draggable="false" alt=""> with a Bitcoin space heater.
