Usually people who are injured get help from friends... (If you need anything from Metro NYC/NJ...:-) (but not this week, Passover is coming :-) My thought is in the spirit of a plug-in Prius mod I read about that changes the Prius minimally, by just giving the battery a nearly "bottomless cup." The Prius is more efficient when the battery is full, and this system keeps it topped off. If an Air Source Heat Pump had a huge heat sink that was in a swimming pool, it would be much more efficient. I don't have a pool, but I plan to put in a ground loop. I have not had a chance to learn how the sanyo talks to its units, but my friend is an expert on that stuff. He is using external controls to improve comfort and efficiency of steam heating. Not sure if he will be able to help. Hoping you heal fast. Seth |

They've got me on so much painkiller it would make Rush Limbaugh envious, so I hardly know what I'm doing...

Sorry to not get back to you sooner, but I had a serious accident on my electric bike, broke my arm in six places, endured two surgeries and will be laid up for some months. All projects on hold for the time being (ALL MY BASE ARE BELONG TO THEM). My typing has always been slow, now it's slower, but I can still type. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Oh My God man, You got to finish this thread!

I didn't say I was dying, just laid up!

Sanyo as heart of GSHP?
And then the details emerge...The mini-splits that I looked at are not Energy Star compliant...which doesn't rule them out, but compare to GSHP which is eligible for the 30%....
or compare with an older AC of "just" 10.0 EER that is free... |

Also interesting is this fuel calculator, which also can calculate CO2 output for various expected COPs. Might make your decision easier. Regards, -AC_Hacker

to seal a pipe fitting try a thin coat of teflon then wrap a string around the thread a few times and then some more teflon tape. tighten it up good and try it out. i guess the string fills the micro-void between the threads and compresses and expands differently than metals. it is also within budget constraints so experimenting is encouraged.

The method of sealing was in response to the leaking heat exchanger you had some time ago. But it seems you have mastered the art of brazing a plate HX. I have learned a great deal from your manifesto. I live in Florida where the ground temp at 30 feet is 74 degrees. I did some crude measuring. The soil at the surface ranged from 98 to 105 degrees. 4 1/2 feet below surface the temp was 83 degrees. Since my heat pump will be rejecting heat I think I may device some sort of cooling tower, a column of water that perhaps can evaporate? Of course i would use a closed loop hydronic system. My main concern is that 83 degrees a little on the warm side, especially at night when the ambient air may be cooler. I guess I need to read some temp charts. But it worries me because the temp is bound to go up naturally let alone rejecting heat into it. And it worries me. But how much more efficient would a heat pump be using a water HX vs Air Hx , if any when you compare the same temp for water and air. It seems like a water pump is more effective than a big fan. Any thoughts? Plus I hope your arm is healing well.
