As we all are aware of how slow our RO/DI water productivity decreases during the winter because of how very cold the water is as compared to how much faster we can make water during the summer. I'm experimenting with increasing the water production by having my input water before the RO/DI pass thru 25 feet of 1/4 inch hose in a 5 gallon bucket with a 100 watt heater set at 70 degrees. Good chance I can go less but I know the cold water passing thru will keep the water in the bucket cool. It'll be a trial effort to know an exact setting for the heater. I put a tight cover on the bucket to eliminate any evaporation. Before I would hear 1 to maybe 3 drops of water within 10 seconds dripping into my 55 gal container. It would take forever. Now I count 12 drops of water produced in 10 seconds. I hoping to have the 55 gal container filled with RO water in a very short time ready for my next water change.
