Yup that's another big reason. At this time of year the water comes out of the tap at around 5C and my garage isn't much warmer. I move them into the house the day before so I only have to heat from room temperature as heating is the longest part of the W/C. With the Pozzani I take about an hour to filter 100 litres and some of that happens while I am doing the W/C.
Hehehee I put my water in gallon jugs, temp with a digital food grade thermometer, then microwave them for 10 seconds per degree of temperature rise. Say my stored water is 71 degrees, and i need it to be 76 degrees, i would microwave a gallon of water for 50 seconds.
Let us all know how the recharge goes, I too have high nitrates out of my tap, around 80ppm and purchased an RO buddy from life aquatics. Without any resin I'm able to get my nitrate levels down to 5 ppm and I am simply looking for something to remove the last 5ppm. My current DI resin will run out in about 8 weeks so i have a little time to find the best solution.
Nitra-zorb will cost about the same as any other solutions out there. I'm leaning towards that however as it sounds like it will be the easiest to recharge, cost a little bit less, and be easy to install. Just remove the DI resin from my current cartridge and replace with nitra-zorb.
Solution 1: Second RO membrane and housing 37$ + Permeate pump 40$ = 77$
Solution 2: Nitra-zorb, about 65$ for 5 bags, since they only come in 8 ounce single pouches.
Solution 3: Pozzani, 40$ + shipping 34$ = 74$
