Is this enough heat to heat the house. I think it's a good idea to make money and not to pay for heating. What do you say? Anyone have experience?

Yes many people up north turn their fan on and circulate the heat throughout their house

I have a friend that has 2kW of rigs in his house, and by his comments I understood that without a good forced airflow to keep the rigs far away from the bedrooms they simply dry too much the air.

There is a small amount of synergy to be had with capturing the waste heat from mining rigs but in general natural gas is a much cheaper energy source to heat a house with compared to electricity. You can lookup efficiency comparisons between natural gas home central air heating systems and an electric space heater. In my region natural gas costs 1/5th that of electricity to produce each BTU of heat.

Is this enough heat to heat the house. I think it's a good idea to make money and not to pay for heating. What do you say? Anyone have experience?

I move my rigs inside into my house (they are usually in the garage) during the winter and literally heat my 1800 square foot house with them. When it gets cold I simply open the door to the office (where the rigs are) and put a fan in the doorway to push the heat into the rest of the house. I can heat the house by about 5-10 degrees just by opening the door and turning on the fan for a few minutes. With the door closed, the office sits at around 80 degrees.

The only issue is that the rigs can be a little loud with office door open and the fan running -- but at least I'm saving money on the heat bill.

I have a one floor house, so I am not sure if this would work with a 2 story house.

My rig consumes about 1kW, so it is OK to heat the room when the temperature is below 10 C.

Natural gas is actually cheaper for heating but it is not needed to operate drilling rigs. What sense to heat the house with natural gas if it is done by drilling rigs which earn at this point coins. I have a small house but I do not have heat. I heat the house with gas. But about 35% of the winter I save.

I've got a few gpu rigs and I plan on spacing them out throughout my house in the winter. A few of them are liquid cooled so I can place them in common areas and still hear myself think lol.

Yes, it's surely possible to heat a room with a GPU mining rig. My humble 6-GPU 1060 rig actually makes my room almost unbearable to stay in during the day. Although my room is not that big, it is enough to fit a bed, study desk, a book shelf, and of course a gaming turned mining-rig (on a table).

The question i'd like to know is if we can afford to increase hashrates a little because of the decrease in temps.

This will be the third Winter in a row I have exclusively used GPU mining to heat my house. I live in a cold climate where winters temperatures often drop below 0 °F (-17.78 °C) and even on "warm" days are normally under 32 °F (0 °C). So yes it is very doable and almost unavoidable, especially if you move a few rigs into your house.

I normally keep most of the rigs in either a shed out in the back yard or in my garage during warmer months, but in the Winter I probably have a dozen rigs scattered throughout the house and it keeps it quite cozy. In fact, I normally have to keep a few windows open even in the Winter to keep it from getting too warm inside. I would say the only time I do have to close most of the windows are the few times the outside temperatures drop down to below -30 °F (-34.44 °C).

So one 5-6 GPU rig will be able to heat most average sized rooms as effectively as a space heater, and depending on the size of your house you can easily heat the whole place with enough rigs.

GoT fan here! Saw the title of your thread and immediately realized that you were talking about mining.

I do believe that one GPU alone is enough to heat a single room especially if it is a properly closed room.

Hello) I live in Novosibirsk, Russia! Now we have a cold night. In the afternoon + 5 ° C, and at night -2. My mines with a total capacity of 1,700 watts. stand on a glassed-in balcony. The temperature is now +30 ° C on the balcony, and on the street now + 1 ° C degrees Celsius. Waiting for the winter to see how they warm up the balcony (2 square meters)

There is definitely a lot of heat that comes of off GPU mining rigs, I don't know if it would be enough to heat an entire home but it would definitely be enough to supplement your heat and allow you to turn down the thermostat a couple of degrees. I have been running the a/c strong all summer with the heat and now that it's getting colder I can already tell the cards are keeping the place a bit warmer than it would normally be. So maybe the lower heating costs will absorb the extra money I spent on a/c all summer!!

It is possible to heat but it does depend on the size of room myself I would not want a rig in my room as I sleep. I have seen some setups where the rig has ducts to spread heat to other rooms.

Dry air? Is that harmful?

Why would the air dry from that little heat generated by computer components anyway?

I heated my condo last year with two A2 Terminators using six quiet fans in each.  Never had to run the heat.
Bought a house this year and I plan to have an Antminer D3 and L3 exhaust into the furnace ductwork.  The heat will passively drift into the house until the gas furnace circulates the hot exhaust along with the warm air.
There Is a humidifier tied to the furnace though pressure in the ducts will prevent water vapor from drifting back to the miners.

Could also use one to heat my garage.

Come spring I may patch them into a basement bathroom exhaust duct.

Near Chicago.

Yes, there are bad effects, that you wouldn't want in your home. Just go to a server room and you know, what I mean. And you will have extra costs on air conditioning and so on.
Here is a thread where experienced members already calculated the heating effects.

To combat too dry of air, they do sell things call humidifiers which can be bought in sizes ranging from humidifying a single room to a whole house. Dry air will result from any heat source that doesn't provide some type of moisture, so mining rigs are no different in that regard. Also, on most furnaces you can run the fan alone without the heat being on, so you can take advantage of this feature to circulate the warm air throughout your house.

Where I live it's not allowed to build a house if it doesn't have a modern ventilation system with heat recovery, I think it's been like that for the last 15-20 years already.

Ventilation unit takes dirty warm air, runs it through a filter and heat exchanger. Waste air is then dumped outside and extracted heat used to warm fresh air which comes through a filter to the exhanger. Fresh warm air is then distributed around to house, efficiency is somewhere in the 80-90% range.

Silent, efficient and works too. There are options to integrate at least heat pump, solar and geothermal heating/ cooling.

Mining rigs can easily heat even a big house even if it's freezing cold outside.
