Wallies, Here it is, the days are technically getting longer, and I have an urge to build something, if not physically (an impossibility) then mentally, and on paper.
This system is going to be the ultimate system, because I'm willing to put some extra in up front that I know will have a terrible return on the investment(ROI) but will cause me to be a net zero energy operation in the long run. That combined with the fact that it will be my summer retirement home, in which I want to pay zero for my energy, dictate design, and sweat equity.
Starting from the bottom (septic system) and working our way to the roof, I would have three underground storage tanks. A standard septic tank with its walls lined, and connected to a water source heat pump. The e with 3/4" pex, insulated with 6" of XPS foam on the exterior heat pump would extract the sensible heat from the effluent tank and transfer it to a second underground super insulated tubed concrete storage tank. This tank would be the thermal RISE pre-heat , or waste heat recovery tank. It would pre-heat all incoming well water (40 degree worst case scenario). I figure I can recover around a 2.5 to 1 C.O.P., so for each BTU I get out of it, I get almost 3 back. Not a bad ROI...
There won't be ANY excess energy going to the leaching field in this home. I'll be capturing arobic, anerobic and thermal BTU's. That in and of itself will probably put a pretty good dent in my utility bill. Hang in there and wait until you see what the electrical source is, you'll love it.
The third tank will act as a Pre Cool or Pre Heat tank, depending upon the time of the season.
The above ground system will be an LP powered condensing , modulating thermal energy converter, whose combustion air inlet will be connected to the attic, where it will collect "free" BTU's that have landed on the roof and saturated the attic area.
There will be a solar thermal system that will be made of Ejaculated Tube Solar Collectors, connected to a large German tank with LOTS of upper and lower coil capacity.
There will also be a Hydrogen Fuel cell generator that will generate the power necessary for the physical plant only (Including WSHP's). When it is operating, it will also generate around 22,000 BTUh of thermal capacity with a maximum temperature approaching 180 degrees F.
There will also be a small solar thermal system that will he available for ANY thermal load within the compound.
Wherever I will have the need to pour concrete, I'm going to take advantage of the cheap, dependable thermal mass (12" thich slabs with copious amounts of input and output circuits on it). There will also be a small solar PV system for communications and internal control logics.
I will be connected to my local rural electrification program, and I can spin the meter backwards if I want to...
Did I forget any thing???
