Single DI

Per bag of resin you get 500000 liters of pure divided by your TDS = 2500 liters

With twin DI you will get 66% more pure water than using single DI. = 4150 liters

thanks for the replies, one 25l bag a month is ok for now £20 aweek

I find it's more about the hassle re-filling than the cost, thankfully my TDS is 55
