Why did you pick this product vs others?: It works as described and at a reasonable price. Be sure to get a heat transfer fluid that is compatible with your system...these systems are not cheap to repair or replace, so don't skimp on consumables that can make them die.

On the road, Amazon delivered! Great top up heat transfer solution for our Alde Heating system in our Tab 400

This is a concentrated product that requires diluting with distilled water. Item worked as advertised.

Exactly what was needed

Works well to replace fluid in AquaHot

This brand is recommended by the AquaHot corporation, therefore I feel comfortable with it's use. I purchased two gallons believing that the overflow tank would require more than one. It required less than 1/3 of a gallon. However, it is nice to have some in reserve for the future.

Used in Aqua MH system… as advertised

OEM it does its job.
