Bio Glycol ... any experience?
Hey Solar Wallsters,
Have any of you ever used a 'bio' glycol in a solar system?
I've recently been reading about a product made by Interstate called Intercool Bio Green.
It seems to have some pretty attractive performance characteristics and the fact that it is made from plants instead of from petroleum products sure seems like a better fit for our values and mission to reduce fossil fuel consumption.
But glycol isn't someplace I want to take risks with an unproven product. Any experience? thoughts?
