Your cart is empty.The Alde Glycol is a high-performance heat transfer fluid specifically designed for an aluminum heating system. It features superior corrosion protection however it is still recommended to replace the fluid every two years. Alde-branded glycol is recognizable by its blue-green color. It is recommended that you do not mix brands of glycol. If the glycol in your current system is a different brand or a color other than blue-green, we advise that you have the system flushed by a trained technician and refilled with Alde-branded glycol.

I replumbed my Alde heater so this was a good time to switch out the fluid to this one as recommended. I thought the price is reasonable considering the free shipping.

Bought this to "top-off" our Alde system as needed. The price on Amazon is comparable to other sellers.

The product was what I ordered but the bottle was open. It was in a sealed plastic bag and I was able to pour the glycol back into the bottle.
