Casco-Marine GeoTronic temp controllers

[MikeyZO]

also sold online as paltech ocean geotronic, has anyone seen or tried any of these as a substitute for chillers and heaters? They're expensive, but they sound like a good substitute for a noisy, heat producing chiller.

No one?

Is this just a fan?

I believe it works on something similar to a radiator principle. Although Im not sure. All I do know is that it both heats and cools your water as needed. supposedly very efficiently.

Looks good but the biggest one only does 250 gallons.. That would heat and cool my sump efficiently..
