| Message: | If you walk into most professional engineering firms and ask them to design you a hydronic heating system OR a solar system, they will grab their manuals that show how to assemble a pressurized glycol loop.
Since pressure goes up and down with temperature, a clever system was devised to maintain a nominal pressure in the loop. A tank, called an expansion tank, is installed in a tee in the line. The expansion tank has a rubber membrane running across the middle. The system fluid fills up one side and air fills the other side. The fluid in the ro water purification system can expand and contract with temperature into the expansion tank, and the air bladder will keep the pressure within a specified range. The air pressure is set with an air hose and tire inflator, just like a car tire. A chart is used to determine the correct pressure according to the temperature of the system at the time. However, expansion tanks have a lifetime. The rubber (or neoprene, or whatever) bladder will someday crack from flexing as it ages and the expansion and pressure regulation benefits of the tank are lost. The system will usually vapor lock somewhere and the whole startup procedure has to be repeated.
