In a previous blog we posted a video that showed how to “get the air out” of your glycol solar heating system when you it. An astute customer realized that since he was planning to mix his glycol with his water he could reduce the number of times he needed to cycle the charging pump by starting with straight water. After he has charged the system with straight water (which doesn’t foam nearly as much as a water/glycol mixture) he can then finish the charge by switching to a bucket of straight glycol. He needs to pay attention to his ratios as well as checking his concentration after he is finished but this process greatly reduces the times he needs to cycle his system to get the air out. By eliminating the issue of foaming in the bucket the charging time is greatly reduced.

Thanks Jason.
