Geothermal System

[JIM MURPHY]

Hello,

Can anyone tell me what the range of acceptable differentials between output and return should be on a Geothermal Packaged heat pump?

Thanks

Jim

Air or water temperatures?

I can only give you the readings from my geothermal heat pump.

Climate Master
Tranquility 27 TT Series (2 stage scroll compressor)
10 KW electric back up
4.5 ton
superdeheater

Horizontal loop
Water temp of incoming 58.5F
Water temp of outgoing 53.6F

Return air temp - 71.1
Supply temp. 97.2
+26.1 difference

These readings were taken Sept 29/10

This is also a great site for geothermal systems.
