Sorry for the hiatus. I was put on a support contract to help California Energy Commission staff write the updated code version of the Residential Compliance Manual and that took me off line for a few months. I have a newfound respect for the hard working folks at the Energy Commission. They truly want the code to be fair, practical and enforceable. All in all, there are many improvements to the code this time around.
Paul Things you need to know about Gerbils Gerbils crave company. You should try to get two gerbils that know each other and have already lived together. While they enjoy company, if you put two gerbils who do not know each other there can be problems. The gerbils may fight and that may lead to injuries or death of one of the gerbils.
This brought me to look up the ideal water to coolant for cold weather usage, and then lead to much more research on cooling systems and how coolant works. I thought it might be a good idea to share results on how the boiling point, freezing point, and heat transfer ability of coolant change depending on the mixture. The freezing point of water as we all know is 0C 32F.
