If HWlabs says yes and koolance says no I will buy a koolance rad
Also, what i don't get is would you have to use Al copper blocks in the loop to keep the rate of oxidation lower? I know people say not to mix copper and al.
If that's true, then what's the rate of heat exchange using a copper block and copper radiator compared to al block and al radiator?
More tests i guess but what ever...
