I do apologise if this is a bit off topic.

This is where I got my prices from http://preev.com/btc/gbp

I actually stumbled into the mining scene after seeing how another guy that keeps koi carp as myself heated his pond............Yes I am a crazy Japanese koi fan.

I actually have a 3kw solar system on my roof, but I never feed back into the grid because I use it all and cannot fit any more than 18 solar panels on my south facing roof.

My koi pool heater is electric and 3kw, so when its on that uses all the power that the solar panels kick out when working at 100%

The theory for me is by using water cooling on the gpus and running the heat exchanger in my koi pond return water feed pipes I will be heating the pond for less than I currently am as the mining rig 6 x R9 280x are only using 1950watts. So in theory I will be heating the pond for less power, allowing the solar panels to feed the rest of the house when at 100% and possibly even feed back into the grid. I will not remove my 3kw pond heater as it is on a thermostat, so if the mining rig ever fails there is a back up, as I am currently heating the pond (2340 uk gallons or 10640 litres) to 17c through the British winter and 27c through the summer, either way I have to pay for that as it is my hobby and I get great pleasure from having my koi.

Once the weather warms up I will be retro fitting the mining rig into the filter house and plumbing the gpu cooling system into the pond water. I saw a guy online in the USA that did something similar who was a big time miner and used his swimming pool to remove the heat from his mining rigs.

So hopefully I will be saving on electric, earning some crypto currency at the same time, doing my bit for my carbon footprint, and possibly making a bit of fiat (cash) too.

I just want to get the rig stable before I place it in the filter house and get other peoples opinions on what they do when the price of electric outweighs what they are earning in crypto currency.

I have thought of the best laid plans of mice and men, and the local burglar coming to steal the mining rig from the filter house (shed) but hopefully my cctv system and the 2 Protection trained Presa Canarios (Curto bloodline from Tenerife) should deter anyone from wanting to risk life and limb for the off chance of a few gpu cards or koi carp LOL.

All opinions and insights appreciated.

Thanks,
Axco.

Sounds like you have an awesome setup and a good plan, I know this is off topic but I'd love to see some pics of your Koi's if you wouldn't mind? Wink
