    No, you can do as many units as your pumps can handle and the BTU's your loop is designed for. I have a 7500 sq foot home with 4 geo systems on one loop. Two for water heating and two for air.

    Seriously, I would LOVE for you to show me where you can purchase an XC80 online because i have never found one. Trane is probably one of the best at ensuring their equipment does not make it online....

    Not really correct information. The XC80 is a better ratings match with some AC and heat pump systems and the TCONT 803 is a good thermostat match for it. While the XC80 works best with a...

    The other option is to still do the 4 ton dual stage but add a dehumidier to the house to help control the humidity during the AC season yet provide 95% of the heat in the heating season.

    So is the 53,000 BTU per hour for the whole home or is that part of the garage and basement. Or is it that the garage and basement are an additional 35K BTU per hour.

    Woah, they installed it without authorization or anybody being home? I would tell them to come pick up their unit and then get the heck off your property, this seems VERY shady or you are not telling...

    For a block load people are going to need to know. Length and height of all walls and what direction they are facing and how much insulation is in them, then the sq footage of windows on that wall....

    Garrett, i had a chance to look over the proposals that Greg provided for you, after talking to him it sounds like the ductless really is the way to go. He did not look at the ducts because he was...

    In our Portland Climate dehumidifiers are fairly rare, but there are a few options that could be looked at. Honeywell and Aprilaire both make good units specifically for this reason but can be spendy...

    I will have to talk to my system designer that came out to see what their consensus was but if we are doing ductless then looking at the ductwork isn't going to add much since they will be abandoned....

    Living in Oregon is not to cheap, but we also pay much more than $20 for a top tech, our best guys made $60K last year. $20 would be for a retro installer with minimal experience or a top new...

    The variable speed trilogy is very new, i think it has only been available for a month or two so who knows how good it is. I do know that climatemaster inflated their ratings to make it "look" like...

    A trilogy 30 or? The Trilogy 30 is not even in the same class as the 7 Series/Sycamore.

    Geostar Sycamore is made at the WaterFurnace factory and is identical as far as I can tell. The area where you have differences is in the number of dealers and tech/warranty support. WaterFurnace...

    It is not the 25' extra of trench, it is more so that the ingrams design said 3 x 100' coils so 300' of pipe in the trench at 100' long typically a slinky is going to be 800' of pipe in a 125' trench...

    First of all I would not trust ANYTHING from Ingrams in that video. Every system I looked at there seems to have a very short loop. Typical amount of pipe is 800' per ton for trench, 600' per ton for...

    Based on everything I am reading and without seeing the unit I think you are setup very well and are setup for optimal savings and comfort. With most geo systems don't worry about setting back the...

    How did you come up with a 2 degree swing saves you $30 a month over a 1 degree swing? That is pretty much impossible.

    There are about 100 variables for how many KW/hr you use for those systems, it depends on high stage or low stage, entering water temps, flow rate size etc....

    That flow rate is low, more water is better and if somebody designs to be in between first and second stage water flow they are wrong, you design for full capacity water flow. If I can not get at...
