I have top of the line mini splits and my real world full year of heating data in my real house. I don't need your spreadsheets.

What people pay for heat varies. Local climate varies and heat source and heat source options vary. If you have geothermal already you may be right. I can't have that and run air to air mini splits. If you are using resistive electric heat for some reason a miner is a no brainer.

In my travel trailer I have found an s9 is the financially best possible heater given the constraints of that environment for example.

Ding ding! I AM running resistive electric heat - and old terrible ones. The reason: house came with them.

You have a guide you'd recommend for turning an s9 into a resistive electric heat replacement? I'm solidly in the "no-brainer swap" category you mentioned.

I got my s9 from the site below.

Add a power supply.

Get one of the 140mm fan options, quieter. Runs Braiins firmware because it gives you more control over output, 100w to 500w per hash board.

Make sure to spread them around breaker wise and stay under your total panel limit.

You will get 5x the sats per watt of electric input from an s19 than a s9 even though they output the same BTU per watt of input. I strongly prefer s19s with a single hash board (600w minimum output for a single hashboard enabled in braiins) unless the higher minimum wattage is too much heat for your space.
