What is Reddit's opinion of 47k BTU Unit Heater Outdoor Furnace Boiler - Single Speed Fan?

From 3.5 billion Reddit comments

so this Heater Outdoor Furnace Boiler (https://www.amazon.com/dp/B00D4CAJLQ/ref=cm\_sw\_r\_apan\_i\_HQW9DV4B4N0ZJCMCQXPF?\_encoding=UTF8&psc=1) is the cooling unit to cool off the entire fluid within the tank? all left is the fluid pump to perform the fluid circulation correct?

i want to build a 8 S19 tank, how much fluid would i need? thanks in advance

My fluid leaving the tank (includes the heat from the miner) is generally around 52-57 degree C. (125-134 degree F) this is the temp of the fluid run through a radiator with a fan (here is what I use https://www.amazon.com/dp/B00D4CAJLQ/ref=cm_sw_r_apan_i_HQW9DV4B4N0ZJCMCQXPF?_encoding=UTF8&psc=1) when placed outside rejects all the heat outside. Because that is hotter than the outside air no tricks are needed. It rejects the heat outside. No need to mess with pressures. And the power is minimal. A small pump and a small fan. (Note you have to make sure to use materials compatible with the fluid) Also there are other options to use this heat for heating water, such as for as with a solar water heater or heat a pool. I hope to implement this later this year.
