So I am going to spend 3X what a 5000 btu window costs to control it?
Sorry, I didn't mean to piss you off about the cost. I just happened to find this while seaching for a way to cool the room my dad is building. Forget I mentioned it
Thanks for the replys. I'm sure I have the pump primed, I opened up all valves and let it flow downhill for a while before turning the pump on. It pumps great as long as the tubes are not raised up too high. The 3/8 tubing may be my problem.
If it's the blue 25' hose that Wal-Mart sells, I bought 2 of them. Within ten minutes of connecting one of them to an outside faucet, I had a major malfunction (blowout). What a piece of s***. It actually claimed to have a 7 year warranty. What a laugh. I took it back.
I'm using 3/8 inch tubing, (if that makes any difference). Can't seem to get much flow above a 3 foot lift. I've shortened the tubing as much as possible but it appears that the most productive flow is 3 ft or less. Is this normal?
I had high hopes that I could pump hot water up to my HLT...
