Fist stage parts are all in and will be brazed up over the weekend. I already did the worst part of copper to steel on the plate hx so the rest should take less than an hour

to do the rest of the first stage. I am still waiting on a few second stage parts. The cardboard box is the placeholder for the second stage compressor, the mapp bottle is a placeholder for the

oil separator and the propane bottle will be the expansion tank.

austin86: Same here in Ohio, not common but it happens, early this week we had ice rain 😮 Oct 17, 2024 8:10:10 GMT -5 *

zila1: Sometimes we have snow on the ground by Halloween. Let's see what happens this year. I only stepped outside twice today. It's just so nice and cozy in the house. Oct 16, 2024 18:11:07 GMT -5

austin86: car was iced over this morning here in ohio too. we be in winter again Oct 16, 2024 8:15:33 GMT -5

zila1: It's a little after midnight now and the thermometer on my deck is reading 29°F. It's nippy out there. Oct 16, 2024 0:11:52 GMT -5

zila1: ShrimpBrime: My crawl space is heated too. My basement is heated real nice too. It's warm and cozy down there. I work out during the winter months down there. Oct 16, 2024 0:08:23 GMT -5

ShrimpBrime: Yep, should snap the trees into dropping the leaves now. Summer to winter in just a week. Gotta love Chicago land!

My crawl space is heated. Cause if not, cold toes all winter on the main level

zila1: I just got a freeze warning for tonight on my pc and my cell phone. I'm gonna go out and drain the outdoor faucets and put freeze covers on them. I like that little added protection. Neighbor down the street forgot last year and his pipes burst. Ugh. Oct 15, 2024 10:59:32 GMT -5

austin86: zila1 my house was rewired by a X old order Amish guy... I know the pain of having to rewire stuff all to well. Fun times ! Oct 14, 2024 12:37:11 GMT -5

austin86: zila1 Hmm ours has a humidifier on it, maybe because its 90% one and not 98%. but now that I think of it I need to drain my heater heater, we never use hot water TBH so I'm sure its not to bad Oct 14, 2024 12:36:04 GMT -5

zila1: I have Peripheral neuropathy and can't take the cold weather very well so I try to prepare my house for it as best I can. Hence all of the stepped up maintenance at this time of year. Oct 14, 2024 12:22:17 GMT -5

zila1: I do this every year in hopes of coasting thru the winter with as little problems as possible. I also have a whole house back-up generator to maintain. 24KW Generac. I love that thing. Easily powers the whole house during an outage. Ice storms can suck. Oct 14, 2024 12:19:23 GMT -5
