In a true geothermal system, you should be using the heat from the ground directly for heating without a heat pump. This can be done anywhere if you drill deep enough.

Clearly, however, I was duly tickled by the one, the church-HP–“water-to-wine!”
…Hmm, wonder if that applies to the opossum-shack?

But if someone is looking forward to installing HVAC products, it sometimes becomes confusing when it comes to its terminology, which was rightly mentioned in the article. Air to a water heat pump is a new terminology you get to know about, and it’s like increasing your HVAC vocabulary.
HAHAHA, Thanks, mate, for this one!!”

It was a pool heater. https://www.hayward-pool.com/shop/en/pools/res-in-ground/res-heaters/heatpro-i-hhpro–1

Yes indeed, Curt! As you point out, if that “radiator” really did transfer heat to the room mainly via radiation, it would also be a fryer.

Bill, I don’t know why I didn’t look there because I have a copy on my desk. Happy New Year to you, too!

Lloyd, your mention of ASHP reminds me that I didn’t really explain that the source in an air-source heat pump is the outdoor air, even though it acts as the sink in summer.

John, yes, you’re right, and I thought about bringing that up in this article. But the cat looked so peaceful, I didn’t want to disturb it. ;~)

Same applies to automotive “radiators” – in fact most heat transfer is via forced convection (vehicle forward motion or fan), not radiation.

Heat transfer components that get hot enough to glow (1600*F +) such as electric or gas fired infrared heaters are properly called radiators, but the cat would be long gone…
