In a regular Purefreedom or Gardiner DI-RO system.
When you fill the water tank, do you have to wait a few hours until the water is clean?
Or does the purifying process work on the fly - like its no problem to fill the tank after you have been working a few hours, then when its empty you just fill it up again and work again?
And btw, does gardiner have some diesel heating system that they do not have on their web page?
