My wife and I are going to be building a new house with geo. I saw a link in a post about a month ago about a monitoring device that can be connected to the geo pipes to monitor performance. I thought I saved the site/info in my favorites but did not and cannot find it doing a search. If anyone knows what thread that discussion was in or has any other info regarding performance monitoring please let me know. Thanks

I have an energy monitoring system for my residence, that includes careful attention to two GSHP units that I have.  See http://welserver.com/WEL0043/ .  I'll be happy to answer any questions.

There are others here on this forum who are using the same item.

And see http://welserver.com/ww/ for implementations that may be near where you are.

Best regards,

Bill

Thank you very much. That is excatly what I was looking for. Bernie

I was looking at some of the samples and they show energy consumption. Do I need to have a seperate meter for the heat pump to be able to collect this data. Thanks Bernie

No.  You don't make any changes with respect to your electric meter.

To measure power consumption for one or more items, you need:

One of these - http://www.welserver.com/store.htm

And one or more of these, depending on what you want to monitor - http://www.ccontrolsys.com/products/pulse_output.html .

In my case, since I'm using an older, no longer available style, of the power measuring device, I have 3 of them - one for total residential consumption, one that covers 2 GSHPs, and one for pool pumps.  By means of subtraction, I get a fourth measurement, that being everything else (lighting, etc.)

Best regards,

Bill

Thanks again.I will probably get 2 of the WattNodes and have one for the GSHP and one for the total consumption. One of the samples on the welserver site I was looking at even had the electrical costs calculated, which is something that I would like to do as well. Thanks again Bernie

You need to order high frequency versions of the WattNodes to maximize the benefit / capability of the WEL.  With my 200 Amp service, for example, my power measuring resolution is 4 watts.

Continental Control Systems now offers the WattNodes in a number of different options.  Give them a call to best understand your options.

Displaying KWH in terms of cost is easy with the WEL - it's simply a scale factor that you apply.

I don't have KWH shown on my charts ( http://welserver.com/WEL0043/  in terms of cost because my KWH rate varies on a month to month basis,

Best regards,

Bill

The Wattnodes have the advantage of being in use with many WEL systems so there's lots of experience out there and I've only heard positive reviews of them so that's probably the best option. Having said that, there are cheaper options out there that could be perfectly adequate depending on what your goals are. Pretty much any power meter with a pulse output can be made to work. I think I paid about $50 for mine. As Bill mentioned, the pulse frequency will dictate your measurement resolution. Mine's lower frequency so I only have 35W resolution, but since I'm using it to measure heat pump power which is never less than 4kW that gives me about 1% accuracy which is plenty good enough. If you want to be able to see individual lights, computers, etc, then you need the high frequency models.
