Today's question is from Kurt. "Hey Dan, can I run Iron Out or bleach through an open-loop geothermal unit that has high iron in well water?" Almost every geothermal manufacturer I'm aware of will not accept any significant level of iron as acceptable water quality. Any significant level of iron is bad. You can try something like Iron Out or CLR, but it's probably not going to remove the iron deposits significantly enough. Some places that have a high iron content probably shouldn't have an open loop geothermal system. But you could still do a closed-loop geothermal. That's still an option.
