    I think I may have stumbled my way into a viable idea on this topic: Rather than use the Geo as the final domestic water heater, I should use it on the preheat tank. Sort of.

    Tell me what you...

    This has me looking at things again and I thought I would add this wrinkle: if I use the existing water heater as the buffer tank and leave it powered (propane) it could effectively serve as an...

    I'm in the home stretch of designing this project (yes, I'm a little slow on it). I have 4 distinct designs that I've settled on (that will find use beyond just this project).

    My "best" design...

    Here's a question I should probably already know the answer to - if you use a dedicated water-to-water unit for the domestic hot water, do you need some kind of heat exchanger between the domestic...

    Question for you guys. I would like to offer the HO the option of generating all their Domestic hot water via Geothermal (with some kind of electric or propane backup). They currently have a 75...

    So the first call for cooling starts running the Geo in cooling mode, but don't you have 50 or so gallons of hot water to get changed over to cold first? Or is the "switch to cooling" something you...

    What type of pipe insulation are you using there?...

    What type of pipe insulation are you using there? Forgive me if it should be well known. I see you are a fan of B&D products - assuming you're doing heating and cooling with water to water units? ...

    I've used the QT non-pressurized flow center for all my installs and love it - I'm going to be trying out their prefabbed pvc manifold with the mechanical fittings for my next one - should save a bit...

    I don't have firsthand experience with it, but what makes you say Arzel's system is superior?
    How many zones are you looking at (2 or 3)?
    Have either of the contractors talked about bypass or...

    If I'm thinking of this the right way, JCT, I would need to have two buffer tanks for conditioned water - one for the hydronic side that would stay hot year round that could serve the floor and...

    So as I'm continuing to research this I discovered that water to water units aren't 2-stage which sort of makes my ideas for how to apply a single larger unit for all my purposes a bit harder or just...

    A couple of things - thanks for the heads up on water temps - I have done a w2w geo yet so I wasn't sure what to expect. I do plan on using the desuperheater with a buffer tank for the domestic -...

    How do you handle domestic hot water in that situation? Do you use the Desuperheater with a buffer tank and then another powered (propane or electric) unit for production? I see the benefit for...

    I actually watched that video earlier today. it looks like a nice installation, although it doesn't have a hydronic radiant application that I can see. Are you using one of the marathon tanks as a...

    Well, unfortunately for the HO, they're on Propane. They've currently got a 73gallon natural draft propane water heater, so while geo hw production might be marginal, it is still far better than...

    In our climate we have a greater heating load than cooling so I size a 2 stage unit for 95% of the heating load and provide some form of auxiliary or backup heat - either gas furnace or electric...

    The synergy system is interesting as is your suggestion of dedicated water-to-water. In theory, if the synergy system is sized to the heat load of the house, the combined radiant and forced air need...

    Yep, in Norwest Indiana/South Chicago where we're at, the higher SEER AC units simply won't pay for themselves in cooling before they die. It has to be a comfort decision to get 2 stages. Now, if...

    Did you get a quote for a variable speed furnace, or is it just a 2-stage? If you're fighting temp differences between the floors, a varialbe speed blower motor running all the time will help...
