Around these parts, New England, standing column systems are generally bored in solid granit. I have no useful experience for solving a sand...
Since geochallenged resurrected this thread, I'll post an update. The system has now operated for 3 heating seasons without drama or mishap. This...
I can't speak to contamination (well, uh, I can - it's bad), but low production isn't necessarily a deal breaker for standing column. My standing...
I echo Eric's points and bring up one more. Pump and dump with a return/dry well is not a fool-proof solution. The increased load on your supply...
Do I understand that you only have 40 feet of water in your well? No easy way to say it - that's not going to work, nor has it ever worked. I...
Ha! Funny. Then again, I did buy top-of-the-line and I'd probably do it again given the opportunity. I'm also very proud of my total system...
O.K. that makes sense - take the efficiency hit at the top end, where you're already taking it anyway. Size the loop field for upper loads +...
Whoops - I read, "does not change the amount of fuel used". Houston, I have understanding :)
I don't think I follow. Granted you can't get a free lunch - but show me a single speed pump properly sized for a full load that isn't an energy...
Sorry - the royal "you" or "them" selling me, I did not mean you personally :) The problem with a 70% turndown and constant speed pump is that...
Sure, $75 in pumping energy isn't too bad - but my entire 6 month New Hampshire heating bill this winter was only $310. As unit COP goes up,...
Damn! There goes my 99 cent profit! Hmmm...I run a semi-open loop...so maybe I can still cater to the 0.00001 percent of customers running...
Really good point, Eric. Unless you can dial down the pumping energy, real world COP won't be nearly as good as it is on paper at 30% loads....
I can easily cover the heating loads with 2 tons. Cooling is another problem - it's not tonnage, it's delivery. With the current plan, the only...
A slightly different take O.K. - with the input here, here's how this could be simplified further. Use common plumbing practices i.e. zone...
Separate names with a comma.
