Doc offers very good advise. In regards to air sealing which he mentioned, make sure you blower door test before you sheet rock. If you want to...
MKutch do you know what your electric draw is when starting up with your intellistart? I also have thought about adding one for the same reason...
Thanks everyone. I found it odd that one unit LWT fluctuates by .2 degrees and the other by 1.5 degrees. Thanks for confirming its normal. I...
Is it normal for the LWT temps to be in constant movement up and down as I showed in the earlier video? Its as if the unit extracts heat for 10...
Hi Doc, you mentioned my LWT temps moving up and down during cycles sounded like the expansion valve was hunting pressure and said nothing...
Working on changing the bottom element on a marathon water heater at my shop. I think it is most likely that the hot water was not cleared from...
Here's my shot at calculating COP. This is 1st stage with desuper turned off. I've found that medium speed on my pumps is giving me the best...
So should it be doing this throughout each cycle? I'm not getting this on the south unit, only the north and seems to never settle in.
Thanks Doc. As soon as I get my low pressure gauge I'll take a shot at heat of extraction and COP. Now on to my north unit. This is the one...
One additional question. I have an energy monitor measuring watts on each unit. The power factor adjustment is set to 1. Am I correct in what I...
I have been focusing on my south unit only. I have something strange going on with my north unit (more on that later). My numbers are suspect...
I have 6 sensi wifi tstats for our house and an additional 3 for our business. I've had them for almost a year now with no problems or...
It looks like around -3% (1033 cfm) seems to be the sweet spot as far as total watts and run-times. I did purchase a pressure gauge. I am...
Am I reading correctly that most of your ductwork is 1). uninsulated and 2.) under the homes crawlspace where temps reach as low as -15C or 5 F?...
I was running the numbers also and couldn't come close to his costs even with the unit running 24/7. Aux heat would have to be running all the time.
