You don't want to be in the middle of the fingerpointing between the designer and the installer when things don't work out. You need one party to...
As we all know, to get to 5 BTU/sqf you need to invest $$$ and you get quickly to the point of no return. We built about 30 net zero houses per...
I think you are missing the big picture here. Geothermal makes the most sense in new builts, since it avoids the costs of a conventional systems...
You can prioritize on the spa for 1/2 hour, or one hour, the house usually has enough thermal mass not to significantly cool down. Can't help...
Figure 2 is usually a conventional piping, Figure 3 is direct to load piping. That way you do not mix the hottest water in the buffer tank with...
Well, indeed not using a titanium heat exchanger for a salt water pool is a major error. Not understanding pressure drop is is also a major error....
Not sure if I agree here. Just saw this. We are building a lot of net zero houses, new construction, and geo makes a lot of sense. The key is to...
Samsung makes a water source HP with multiple heads
Depending on the design of the radiant floors. New built well insulated house, with protruded aluminum plates under tile floor: 85F degrees max...
http://welserver.com/WEL0877/ We have built similar systems, with a NDW doing both floor heat and pool heat. See link above. There is nothing...
Concerning that a contractor states that vertical is more efficient than horizontal. One can make a horizontal system much more efficient than a...
So if you go with 8x 600 ft loops, instead of 6 x 800 ft, your total system pressure drop with go up by 25%, usually meaning 25% higher pumping...
Looplink is very good for the loops, but does not represent the energy use and the associated operating costs very good. It overestimates the air...
There is some silliness here behind Massachusetts and methanol. they want you to report when 2 gallons of ethanol get spilled, and they banned...
"The results suggest that keeping design pressure loss relatively low, as suggested by Mescher (2011) is more important than keeping the flow...
"105 LWT and 96LWT in afternoon" I assume that you mean 105 LWT and 96 EWT. Still pretty high. It also seems that your ductwork might not be well...
I have seen freeze up when the loops were under the leach field, but only 1-2 ft below. Keep in mind, during freezing conditions, your frost line...
Yep...you don't gain much, you get to the point of no returns. You can get a NSW, but the one designed for portable water (with a double walled...
yes, the 25-124 has lesser max pressure than the 32-140. It is usually 0.5 gpm less, not really relevant.\ If I were you, I would run 10 lines...
Well,.... I do design for geo, and if you put the geo right underneath, it is an issue. Just make sure you don't blame geo when your septic system...
