Here's some pictures of the set up. The first two are of the plumbing inside the garage, the third one is the fish room from inside the garage and the fourth is the fish room from inside the house. The house is currently at 70 degrees. The temperature inside the fish room doesnt feel to have much of a change from the house, plus the QT tank is staying at a steady 77 degrees so I dont believe any of the heat is coming from in there. The plumbing inside the garage does run behind the furnace but it hasnt been on for the past 3 months. I knew this could result in a problem once it was time to heat the house but was hoping that the insulation plus the fact the water is flowing quickly by it would prevent this from becoming another headache. I currently have an AC unit pushing cold air onto the pump to see if this helps the problem and I opened the 2" ball valve right outside the pump completely then restricted the flow with each 1" ball valve to the individual returns. I've also called and emailed dolphin to hear what their ideas were on the issue and if they believe since the pump has so much restriction its causing the water to heat up.
So if my problem doesnt improve, whats everyones thought on A) get a smaller pump? B) get a chiller?
If I must get a chiller I was thinking it would need to be around a 1/2-3/4hp depending on brand. Any suggestions on chillers to look at? Most of them have a 3/4 to 1" draw and return to them with around 1200-1700gph max flow. Would this mean I just have it draw from my sump and return back to the sump since this amount of return can't even come close to my pump and what my returns need? I have no experience at all with them so any info is much appreciated.
edit: I've been looking at the Pacific Coast C-500 1/2HP. Chiller, that's rated to chill 450g 10degrees or 240 30degrees. Any thoughts????
Right now I'm leaning towards getting a new pump. I've left a message with tenecor to get the approximate rating for my overflows. I just don't see anything besides the pump creating my problem. I wish I would have put more thought into my initial pump purchase rather than wanting to oversize to stay away from powerheads and not putting much consideration into my overflows.
I'm also trying to think of what else I can plumb my pump to in order to get it more work, I've allready got a line T'd back to the sump with a ball valve in order to pump water into my refug then just have it overflow back to the sump
