What makes it “organic”?

@Michael Z .I don't know..
That's what I'd like to know.

I don't understand some of the usages of "organic" any more.
OK, organic produce and other food, I understand. They didn't use pesticides, hormones, etc. to grow it. Got it.
But "organic" is getting thrown around indiscriminately these days. Everything's "organic"....look at this house...it's so organic. Look at our life...we're so organic. Look at this sweater...it's so organic. Someone described her relationship with her boyfriend..."we have such an organic relationship!" What, she's engaged to a radish?

There’s no distinct category of heat pumps labeled “organic” in mainstream use. The term likely describes a standard heat pump (air-source, ground-source, etc.) that uses an organic refrigerant.
I suspect it's a marketing term in places pushing for greener tech.

@jujube Just think about how we got used to "cool". 
It is a real product. I'm no expert but it sounds good.
Storage of electricity from fluctuating renewable energy sources has become one of the predominant challenges in future energy systems. A novel system comprises the combination of a heat pump and an Organic Rankine Cycle (ORC) with a simple hot water storage tank. The heat pump upgrades low temperature heat with excess power. The upgraded heat can drive an Organic Rankine Process using the heat pump in reverse operation mode.
This approach allows a comparably efficient storage of excess electricity. Waste heat sources usually do not qualify for electricity production even with ORC processes due to low temperatures. Upgrading the temperature of the waste heat by means of excess electricity makes the use of an ORC feasible in order to recover the electricity input. Thermodynamic cycle simulations with IPSEpro software outline that the process provides power-to-power efficiencies in a range of 50% for small-scale applications based on commercially available heat pump components. The isentropic efficiency of compressors/expanders plays a crucial role on the system performance. Applications of the proposed cycle in the megawatt range with more efficient turbines and dynamic compressors will therefore increase the power-to-power efficiency to above 70%.

My first thought is that they may be alluding to geothermal heat pumps, since refrigerant isn't used.
Air temperatures above ground change throughout the day and with the seasons, but the temps of the earth 10 feet below ground are relatively consistent between 50 and 60 deg. For most of the US, this means soil temps are usually warmer than the air in winter and cooler than the air in summer. It just needs a sufficient length of underground conduit, and a fan to push the air through it.
