distilled/deionised???

Tech spec says my 02 blades coolant/anti freeze should be a 50/50 mix of coolant (ethylene glycol) and distilled water...

i know they're slightly different in purity, but would there be any harm in using deionised water in place of distilled?? the price difference is crazy!!

james..

i did look into it.. (research.. not the bowl of water)  :wacko:

and i see yours and units view.... some places say rain water is distilled by the natural process of evaporation and condensation.. (clouds) others say it is contaminated as it falls....

 might have a go at some simple distilling meself just for the hell of it.. :biggrin: boil from a large pot via a cooled hose into a britta filter jug...  sorted...

So

is the water collected from a dehumidifier distilled or deionised?

just buy pre-mixed

you can also get coolant that is pre mixed ready to go from your local bike shop or auto store so you won't have to worry if its mixed correctly or has the wrong type of water in it :sunglasses::sunglasses:

"Is the water collected from a dehumidifier distilled or deionised? "

A good question, Smidget, you got me thinking again.

 

We’re expanding the original question of whether ‘deionised’ and ‘distilled’ are significantly different in terms of radiator fluid requirements. Strictly, the technique of distillation is the act of heating a mixture so that the components are separated based upon their volatility. The component with the lowest boiling point vaporises first and the pure vapour can then be isolated and cooled so that it condenses into a separate container.

 

With electric de-humidifiers (and fridges which Gunger mentioned elsewhere) there is no prior purification step; ie. the heating stage which fills the condenser with water vapour and only water vapour. The air is chilled, water condenses and falls into the collection box. If there is tobacco smoke or bacteria in the air it is likely to contaminate the condensate just as Preunit suggested with rainwater. Whether you’d regard that as a problem would depend on whether you plan to put it in your radiator or drink it, but it will be limescale-free.

 

In this context I should have described rainwater as “deionised” or just “purified” rather than “distilled” in an earlier post, so Preunit was right to say rain isn’t strictly “distilled”. The degree of de-ionisation/ purification also becomes important. Brutale r gets into that with conductivity measurements on the “I’m brewing WATER!!!” thread.
