No, it is not.

WTF is the matter with you?
Why the obsessive compulsion to post about things you know nothing about?
Have you put that is the Wiki thing?

Automotive antifreeze is almost always ethylene glycol. It is very toxic and has a sweet taste.

Antifreeze used in domestic heating systems is propylene glycol which is non-toxic; there is a risk of contaminating the DCWS through a leaking cylinder coil. It is used as a sweetener in the food industry, so sweet it would put your teeth on edge, apparently. This is the stuff that was being used to adulterate wine a decade or so back.

Methanol was used as anti-freeze, before the glycols became commonly available. It isn't used now because of the hazards (volatile liquid) and the cost.
