Has anybody ever plumbed in a inline water heater before ro?

Water production is really low due to this cold weather we've been having.

Thanks

Slightly slower but you shouldn't really notice that much of a difference, you may find with all the leaks and problems caused by the
bad weather your tap pressure may have dropped slightly causing the slowdown.

Not sure if anybody has, but ive been searching online for replacement sediment filters and seen one company selling hot water sediment filters and the like so I guess some must be.

On the subject of replacing my pre filters I dont seem to be finding anyone selling fiberdyne filters apart from the states. Does anybody know where I can order 10inch ones from?

Forget that, just seen gardiner sells them 👍

Ro is rated at 25c to give optimum performance and the tap temperature today was only 9.5c. Looking at charts referring to ro performance that drop in temperature equates to 50% less water produced.
Not that long ago it was 6c and that would only be producing 30%. Surely it's not just my production that slows down massively during the colder months

I maintain 75psi input pressure winter and summer, but the temperature difference still makes a massive difference in the output from my RO in the winter, both in rate of output and pure to waste ratio

My 4040 RO is in my van and there's no noticeable slow down at this time of the year, I do have very good tap pressure though so
that could be the reason.

My 450gpd used to produce 300 Ltrs in 12 hours due to the cold weather. It got quite stressful , worrying whether il have enough water so I bought a 4040 from daqua on a 0% credit card which gives me 27 months interest free to pay it off.
I now get about 120 Ltrs an hour and no more worrying, it’d be a good investment for your business

How much is it going to cost you to heat the water from 8 or 9 degrees C to 25 degrees C so you can get a quicker fill?

I'm not even sure of the logistics of how you would do that and still maintain the pressure you need to work the r/o at its optimum.

If you are using 500 liters a day and your r/o is set at 60/40 then you are going to be heating/warming  1250 liters and just sending 750 liters straight to the drain. If you have a RoMan type of r/o, our inline, non adjustable restrictor was preset to 1 pure to 3 waste. So with that r/o you would be heating 2000 liters and sending 1500 liters directly to the drain.

If you are struggling with the amount to water you are getting from your r/o due to the weather, then, as Shrek says, it would be cheaper to buy a 4040 and solve the problem that way.

I would only need to warm it up to approx 15 to get the production I need to get by. Pressure does not matter as it'll be pumped after heater. The heater can up the temp to an increase of 30c but that would be using the full 5.5kw.

A 4040 does not work as it would need to be pumped all year round and that would cost me far more to produce that way than using 2 x 300gpd ro's.

I've looked into all options and staying with the smaller systems works best for me, accept for around this time of year when it gets very cold
