Yes, there are more practical ways to use the excess heat.

Do you all live in in very tiny houses or have a aquarium serving as swimming pool?

Depends on the size of the rig. 10kW would probably heat a house or warm a swimming pool.
It would certainly make sense if mining farms were encouraged to find uses for the waste heat rather than just pumping it into the atmosphere (or even worse using aircon to cool the rigs) eg. heating homes, commercial premises or a municipal swimming pool.
If you have a swimming pool measuring 10 meters by 5 meters and 2 meters deep, and you have to heat it up from 50°F to 82.4°F, you need 2,512.20 KWH of electricity.
To maintain the temperature, assuming temp goes down at night from 82.4 to 80.6, you need every day 139.57 KWH. This means 5.81 KW each hour 24/7.
- heated in 24 hours: 2,512.20 KWH per day
- heated in 48 hours: 1,256.10 KWH per day
- heated in 72 hours: 837.40 KWH per day
- heated in 96 hours: 628.05 KWH per day
So my guess of a 10kW rig (2,400kWh/day) should do the job.
10Kw per Hour is 240Kwh per day, not 2,400kWh/day.
