Not as good as a proper heat exchanger but it does work pretty well. Good solution while you either build up a proper unit or wait until spring to do it right. Use distilled water and RV antifreeze (propylene glycol, safer than car antifreeze) as the fluid.
You'll probably want to swap the cap tube for a TXV once you put in a proper heat exchanger since TXVs are cheap on the surplus market and they improve efficiency. Don't forget to replace the filter drier as well. |
We wouldnt know what to do if it got below freezing for very long. It is usuallly pretty mild winters butas far as waiting until spring. Im guessing reason ya say that is because snow maybe ? We dont get that here very much thankfully. Although white christmases are nice. Good link though
