If you are like me, when taking measurements, you can never have enough data points.
After having Palace Geothermal install our heat-pump, I was left wanting to know more details about the various temperatures inside the heat-pump:
- Ground Loop Temperature In
- Ground Loop Temperature Out
- Tap Water Temperature In
- Passive Water Heater Temp Out
- HWG Temperature In
- HWG Temperature Out
To name a few.
There were options to purchase a $800 diagnostic unit so I could read these temperatures directly from the heat-pumps internal computer but for me, that was way too much money for a “nice to have” feature.
After a little Internet searching I found retailers that sold tiny, little digital temperature probes. They were $1.39 on eBay. I bought 6 to start with.
They even came with their own button batteries. I attached the probes to various pipes of which I was interested in knowing temperature. A thick layer of foam insulation over the pipe allows the probe to report an accurate water temperature without being effected by the ambient air temperature.
Using old hard drive magnets I can stick them on any metal surface with ease.
They worked so well, I have since bought 6 more.
In addition to the 6 parameters I was already monitoring, I can now view:
- Return Air Temperature In
- Air Temperature Out
- Drain water temperature In
- Drain water temperature Out
- Culinary water temperature In
- Culinary water temperature Out
But they are extremely handy for at a glance seeing what every piece of the pie is doing.
