Aqua Hot performance

[George Burke]

Hello Wayne, Read your post with interest, and had to get up and check downstairs on my antifreeze jug, which is the Extended life 5 yr. or 50,000 mile stuff. This antifreeze is better than the older variety, and at 50/50 will protect down to -34 degrees. At 70/30, it goes down to -84 degrees, with your 60/40 mix being somewhere in between. Here in the Charlotte, N.C. area, I don't think that in my life its ever gotten below 5 or 6 degrees, so I will use 0 as a base. You are getting on the right track by lowering your mixture ratio, because water is still the best at transferring heat, but of course it doesn't offer much freeze protection. I have always used a 50/50 mix here, mainly because the anti-corrosive properties are higher at that ratio, not that I needed the lower freeze protection. Of course all the mfg.s of this stuff recommended  a 50/50/ mix, even in the south. They love to sell you more. I now wonder if this newer 5 yr. stuff has a higher amount of anti-corrosive properties in it, and then I could get away with using  a 40 antifreeze/60 water mixture, being getting rid of heat is needed more here than anything else. I don't know where you are from, or where you travel to, as your last couple of posts don't say, but I wouldn't use any higher mixture than necessary to protect your Bird. Good Luck with your problem, I hope you get it solved soon. Are there any experts here on this forum that have kept up with the new and improved 5 yr. antifreeze? If so, I would like to know the latest on this stuff. You use to be able to replenish your antifreezes anticorrosive ability yrs. ago, but I haven't seen or even heard of it in many years. Anyone know if it is still available? Hope I have helped you a bit. Regards, George Burke 1977 FC31 Charlotte

Marty insulating the hoses is a good idea and insulating the windows, I think those single pane windows are like large heat exchangers radiating cold into the rv. I took my inside  warmer (53 deg F).

If your 3 electric toe kick heaters will keep the coach warm and they produce a couple of thousand BTUs each, it only makes since that the A/H should do a better job as they produce 2 times the heat, each. There must be a problem? I do a lot of cold camping, last weekend it was 9 deg in Republic WA. and I keep the coach at the temp I wanted. I have done a few things to improve the system. All the hoses run along the side of the coach next to the exterior skin in the bays, so I moved them a little and encased them in pipe insulation everywhere I could, and two of the hoses ran outside to the front of the coach so I encased those in pipe insulation. One thing I do know is that the burner runs a lot when it's that cold, and diesel cost a lot, so I too heat with electric and supplement with the A/H. I also made window inserts out of ¼" white packing foam stuff, and keep the blinds down except in the sun.
