In earlier posts I suggested the unit might not be making much of a...
I should have added this link to my previous post. This is the accumulator with the heat exchanger built in...

Is this sort of set up common in industry or other refrigeration equipment? I know that the intent is to prevent liquid from returning...
I am no expert in refrigeration, but will do my best with your questions...
In doing a comparison of resistance heat vs the heat pump, I find that the system is not saving much if anything. In this I have estimated the pumping power for water (that the heat is removed from) and the power used...
I will be getting the unit inspected and tested, but I want to get it set right the first time.
Should I consider changing the refrigerant to one of the newer tech gasses? The efficiency is not good now, will this help? What changes in the rest of the system will be needed (huge question). I...
Thanks for all the information. I am in Canada, but still do not intend a DIY fix. I am sure it will be better to get a pro to work through the issues.
One web page I looked at suggests the installation of a thermostatic expansion valve in place of the fixed valve that the system has. Is this a...
Thanks for the quick replys...

-By Service, it seems to me that the unit is not operating with good efficiency. The secondary heat is on with a high duty cycle at outside temp -10C. Second heat starts up when the outside temperature is about 0C. I believe that the unit may be...
I am seeking information regarding an R22 based geo-thermal heat pump. I have limited knowledge of refrigeration but wish to be on top of required service. The manufacturer no longer exists and little information was provided.
The system is an integrated unit. A plate inside specifies R22...
