Hi Everyone, Panel Layout & Generation I would appreciate some feedback on my planned rooftop solar panel layout and the estimated power production, from your firsthand knowledge and experience. Power Production Spreadsheet (Google Drive) Summary Below are the summary figures showing when we...

Just some more data, direct from our electricity supplier MetEd, PA. Barcharts showing total household electricity usage, including heat pump for 2023. For a breakdown of just heat pump usage, and heat pump as a percentage of the total kWh, please look at the spreadsheet referenced in the...

@SunDave I so appreciate the offers for help from you all. For now I think we have the problem solved, as much as can be. Hoping the sound box topper will capture the last remaining little bit of hum that I hear. Partimewages pointed out a relevent fact, that I am hyper sensitive to noise...

Thanks so much.

@Partimewages Not an audio engineer...just a man whose wife moved to the living room to sleep on the couch and knew he had to find a solution damn quick, having been the one to convinced her to go geothermal and spend a large sum of money. I felt deeply responsible and that it was definitely...

Mostly fixed now, I wrote about it in the initial post. The unit was initially installed on a concrete floor and directly on cinderblock (by my request to elevate the unit above occassional basement floods in really heavy rains) and the pipes screwed into the ceiling/floor joists with U clamps...

How geothermal works is really fascinating, thank you for that expansion/contraction insight. Half the fun of getting the system was doing the initial research then watching all the work in progress, drilling, install, commissioning, plus learning how things really work in practice. It is such...

There is an interesting issue with decreased ground loop pressurization and increased vibration with our system. I found that when the pressure in the ground loops is lower than recommended specification, then vibration amplitude can increase in the ground loop pipes. The standard pressure for...

@Partimewages & @Supervstech Thanks for the clear information and experience behind the preference, much appreciated.

@SunDave What a great flexible plenum to ductwork connection, thank you. When we redo the ductwork I will ask the installer to add a similar flex connection into the system at the plenum. I think these flex connections both help with vibration suppression and help reduce sound transmission...

@SunDave Your temperatures are way lower than ours. Not sure if that was celcius -40C or farenheight -40F. I agree that once the air temperatures have dropped that low, you are likely almost completely running on a supplemental heat source, even with the best air source heat pumps today. Our...

@NC_hydro thanks for the comment, these are options that I have not researched at this time so would need to do some homework.

@millsan1 Good points on the well power draw costs of open v closed loop. Which system is right for each ground condition circustance and homeowner aims, really does take some careful assessment. How much land is available, the depth of water table, quantity of water flow and whether the...

@x98myers7 I hear you on the wood chopping, I had that in our previous home for just a pleasure burning wood fireplace. Chain saw bucking, chopping, stacking, hauling wood takes work. The mice always seemed to be most appreciate the luxury wood stack condominiums we built for them outside by...

@Real007 thanks for sharing your system experiences, all great ways to do geothermal and good information to share for those thinking about it. Definitely if you can do the work yourself it will save a ton of money as per your figures. I relied on the contractor, not personally having the...
