use air compressor excess heat for hot water?

Has anyone on this list gotten any ideas on this. A product seems to exist in other hemispheres but no the USA.

It looks like it may just be a heat exchange and plumbing relief valve. I'm sure somebody on this board has already connected the oil lines to a hot water heat exchange.

I think the way to go about it would be to find the oil pressure and temperature range for my compressor.
select a heat exchange that can be used with oil and water and withstand the temperature.

On the water side plumb for pressure relief. My heat exchange will be plumbed into my main heating hot water loop as a heat source.

At that point I can remove the fan blade from the shaft and remove the oil to air heat exchange.

Am I missing something?
