    I need to replace solar fluid in my evacuated tube. Where I can buy that?

    Would engine coolant be suitable?

    Any of the local plumbing shops will be able to supply you a 10 litre drum at €50
    You cannot use normal anti freeze as it's toxic and if the coil within the cylinder ever leaked you would kill everybody in the house
    Glycol is non toxic
    Why do you need the fluid? OP

    Anyone know how much to put into the system. I have 20l but cant find a water to fluid ratio any where.

    It normally comes ready mixed. That is ready to use. Every add I looked at said ready mixed.
