I think CM 27 has around 37500 btu in first stage heating. So Flow would be around =12.8 gpm . My loops are total = 940 feet to header . From...
First stage.
My delta-T 6f. Ewt 37f Lwt 31f. The other thing is when unit goes in second stage ewt drop very fast.
I just double checked my pressure readings before I called installer. It's the same 31psi in 24 psi back. I'll compare my reading with installer...
My loops are 3/4 . 20% Methanol. I just talk to installer. Hi said that this is the smallest pump they make. His gonna put valve to restrict the...
It's a new system installed in October. PSI device is brand new, i bought it on ebay 75$. Flow center products BGM 136, PL36 230 VAC 1.1 A Cast Iron.
I just got second email from CM. They talking about using 3-way to slow the flow. What do you think about this? Is it gonna do some damage to the...
I have a Climatemaster 5 ton unit with one single flow pump. (5 loops 200ft deep), return closed header. My pressure drop across the coil is 7...
Can anybody explain this. Why his pressure drop did not change if hi lowered the flow speed? I didn't get that. My system is opposite I have 7psi...
Thanking you all!
At 7 psi pressure drop how many gpm do I have? Compare to manufactures specs.
Can I use them to slow down my gpm. What other options do I have?
Pump has two regulator on the sides. I heard you can tweak them a lil bit to get batter performance.
Is any adjustment on my flow pump? So I can make it to match the specs. I attached pic of flow center.
