It's summer, and some miners are probably battling the excess heat and what to do with it.

In this article, I combined some of the potential ideas of how you could reuse the excess heat of your ASICs (or gpu rigs).

How to use the excess heat from ASICs?

#1 Dispose it

The most common thing (sadly) is to dispose of the excess heat. Since the ASICs need to run at cold temperatures, this is the easiest way to cool the room.

This can be done by opening the window for the air to passively pass through.

Or you can get more creative and create a cold/hot zone, where ASICs will automatically use the cold air and push it out to the hot zone. Using hot/cold zones is also recommended to lower the temperature of the ASICs. Since ASICs will create a positive pressure on the hot zone, all you need to do is to open a window and the hot air will escape there.

#2 Heat a garage, basement or even other living environment

This is probably the second most used way of reusing the excess heat from the ASICs or mining rigs. It has a downside that it can only be used in the winter.

It can be done passively - just by placing the ASIC in the room and letting it run.

Alternatively, you can get more creative by using an exhaust pipe to direct the heat to other rooms. Read this article on Bitcoinmagazine by Robert Warren and learn how he managed to reuse the heat from its ASIC.

#3 Store the energy / heat the water

The third option is to use a thermal energy storage to heat up the water for your house. This is very similar princip to the one with using a big insulated water tank that some of you might already use in residential houses.

Products like KryptoHeat allow you to store the heat from mining and use it later for heating up the water in your house. You can also check what Linus from Linus Tech Tips is doing to heat up his pool here.

Imagine using systems that store excess ASIC heat in a hotel. A hotel would be running a couple dozen of ASICs in the basement and use it to heat the water of its guests. The hotel would actually be paid instead of paying to heat up the water.

#4 Heat up a greenhouse

A bit of a wild idea to put an ASIC in a greenhouse, but if you manage to do it safely, you could be planting tomatoes all year round!

Instead of physically puting ASIC in the greenhouse, you could instead use an exhaust pipe and move that heat from the remote shed.

You can also do this on a large scale. Imagine heating up an industrial greenhouse and using 100 ASICs to do so. The owner would probably earn more with mining than growing crops.

#5 Dry the wood, clothes, or anything else

Similar to the above idea of heating up a greenhouse, you heat up a woodshack to dry the wood for winter. Or, alternatively, you could use the heat to dry the wooden planks faster.

Again, this can be used on an industrial scale where large sawmill companies could dry the planks and other wood products.

Conclusion

ASIC mining becomes environmentally friendly in a moment when it uses its excess heat for any secondary use.

If one uses ASICs to dry the wooden planks instead of a dedicated heater whose only function is to heat up the air and dry the planks, does an ASIC primarily act as a heater or a mining device? At that point, it is hard to tell what is the primary function of ASICs. This is the point where ASIC mining becomes environmentally friendly. It does two (or even more) functions at the cost of one.
