Warming RO water?

[Myka]

Are you talking top up or waterchanges? Either way...bucket with heater.

I dont warm for top-ups. But then, only using 1/2g for TU, added to sump, doesnt change tank temp

The only thing you can do is add a pump and make sure your pressure into your RO unit is 65 psi constantly. (if it is already then forget the pump)

It would cost you a lot more money to warm your feed water with a heater than it would to simply waste more water. (electricity is much more expensive than water)

One other possible option is to coil your RO feed tubing in your sump. This will cool your tank water as well as heat your RO feed water. You must be careful not to cool your tank water too much though otherwise your heater will run and you are back to square one.

You could always tap into you hot water feed line as put a valve and then take it to you RO aswell....this way you can add a little hot water to bring them temp up!

im not certain but im sure that i read your ro unit will work better with cold water then hot so dont tap your hot water line.

RO membranes are suppose to produce better around 77degrees water temp. I'm getting major condensation on all my RO lines, which has never happened before, so my water is very cold, which will cause you to lose performance. Right now I am getting around 80 psi to my membrane.

Correct they work best in that 25 degree Celcius temp range and the last time I checked the temp of the water coming out of my tap it was like around 16 degree's celcius
