Duane's World
The scope of this project was easy. My furnace and air conditioner were in dire need of replacement. The firebox was already rusted through. I think that if I had kept the system, this would have been the year for a carbon monoxide lesson.

Bottom line was to replace the existing natural gas furnace and electric air conditioner.<P>

Geothermal on a Budget
Having become very frustrated with magazine articles where McMansion's were used to demonstrate the economies (''Our New Home is 100% Geothermal and the geothermal system only cost $ 350,000'') and vendor quotes (''your geothermal system will cost $ 47,000...$ 93,000), I decided to build a geothermal home ''on a budget''. Where the local HVAC company wanted $ 27,000 for the 5 Ton heat pump, installed, I took factory training, purchased the same pump from the factory for $4,700 and installed it myself.

Likewise, where radiant heating was quoted at between $30,000 and $ 45,000, we got a very detailed design and the complete installation kit from the great folks at www.nrt.com and installed it with a bit of help from the plumber. The result is a 6 zone radiant system operated by a Climate Master 5 ton (turns out to be much more than we needed, typical HVAC over-sizing...see graphs) water to water Geothermal Heat pump operating off our domestic water well. First year ran just over $ 1,200 for both heat and hot water. We expect to do better next year, since we're fixing all the sloppy air infiltration our awful builder didn't do properly.

Harvest House
We have a modern, sustainably-built home in Pullman, WA, which has recently received an NW EnergyStar certification. It was designed and built by Dyonne Davidson (IRIS Design Works) and R. Lane Brown. The exterior walls of the first level are FasWall blocks (R-26), coated on the exterior with a concrete-based stucco, and on the inside with a lime-based plaster (EcoStucco). The upper level uses double-stud or lattice-style construction to minimize thermal bridging, and is filled with open-cell foam (Demilec Sealection500) to R-36 and R-28, respectively. The unvented roof is filled with closed-cell foam (Demilec HeatLockSoy200) to R-40+ between the I-beam roof support. The majority of the windows are Atrium triple-pain vinyl windows (U value 0.22). The roofing material is a mechanically-rolled standing seam roof. The solar thermal system was designed and installed in collaboration with Todd Hoitsma from LiquidSolar of Bozeman, MT. We have eight 4x10 solar thermal panels at 23 degrees on a S-facing shed roof. The heat is transferred to a 350 gallon storage tank. The heat from this tank is used to heat domestic water in a Triangle Tube indirect water heater and used for space heating by charging a high-mass sandbed, which lies in an insulated foundation under the polished concrete slab flooring. Fourty-five percent of the glazing is on the S side (would have been more, except for a fantastic view to the East) with overhangs to provide shade during the summer months. During the winter months, this provides passive heating of the dark concrete floor slab. For backup space heating and domestic hot water, we have a Viessmann boiler (95% efficient).

Our Southington Residence
We have a ground source heat pump (GSHP) Envision Series from WaterFurnace that was installed in the fall of 2008 to heat & cool our home. The system has a closed loop with a pressurized GeoLink Flow Center FC2-FPT with two Grundfos pumps (TYP UP 26-99) and 3 vertical bores at 225 feet each with 1.25'' HDPE pipe. The geothermal loop is running with methanol diluted at 20%. The GSHP is controlled by a TZ-4 TotalZone Zone Control panel from Honeywell. The Envision unit is running with the IntelliStart component to preserve the life of the compressor,reduce light flicker, and diminish start-up noise from the unit by reducing the start-up current to just 30% of normal starting amperage.

We also have a Marathon (MR50245) 50 Gallon 4500 Watts Electric Water heater.

Our house was built in 2002. The house is 2500 square feet with 2'' by 6'' framing on exterior walls and R19 insulation. The attic has R30 insulation. The house has Andersen Windows with high performance glass.

The geothermal heat pump replaced an inefficient Hallmark oil fired furnace. The Marathon water heater replaced a Bock oil water heater. We have cut our dependency on fossil fuels as we no longer need oil to heat our home or our domestic hot water.

The WEL is helping us get a better understanding of how our system is performing and helps us monitor in greater detail our temperature sensor data and monthly heating and cooling costs.

Countryside house, with geothermal heat source, and forced air ducts.

I hope to monitor the behavior of the the geothermal unit,
and validate that it does not use the backup electric element too much.

As I am going to do some monitoring, I also intend to monitor many points in the house to see how well the whole setup is balanced.

Finally, I am also monitoring the electric current at many points, and I want to correlate all this.

Started operation in may, 2011. First logging setup completed in march, 2012.

La maison de Normand et Denise
I installed the WEL to monitor real time energy consumption and the performance of my 2 ton GeoConfort two stage geothermal unit, desuperheater and a heat pump HRV.
GeoConfort geothermal two stage heat pump (2 tons): The unit is undersized due to utility room size constaints but I compensated with an oversized vertical loop 540 feet deep using 1 1/4'' polyethylene tubing with 25% methanol. I will try to lower the antifreeze concentration in the future. I keep a constant ambient temperature day/night using 1 cycle per hour.
DHWH: The two element hot water heater (11 years old) will be replace with a three element unit shortly. The lower element is on a timer and operates only once a day in the early morning hours to kill any bacteria and is deactivated from around December to March when the desuperheater heat is sufficient.
Tonn-Air heat pump HRV (3/4 ton): When installed in the spring, it will run automatically on demand and will be controlled by CO2 levels and/or air quality monitors and humidity sensors in bathrooms. The compressor will only operate in cooling mode and in heating mode only on the coldest winter days.

3,265 sf home under construction with 3-ton GeoComfort closed loop GSHP. Horizontal loop field is 3200' of 3/4'' HDPE in four, flat slinky runs buried at 7 feet in poor soil. Trench lengths are 87 feet long by 42'' wide, and wing outward at 180° from two header pits near front and back of house. All slinkies encased in one foot of compacted, fine silt that holds water very well. At the 2-foot level above each trench, 4'' diameter, laser-leveled leach pipes in drain rock (covered by industrial fabric and buried) deliver downspout and surface drainage to ''water'' the trenches, keeping the loop pipes surrounded by wetter, more conductive silt.

System will also contain three ducted zones w/thermostats, a de-superheater loop to a two-tank DHW system, timed circulation to hot water use points, heat recovery ventilator, electronic air filter, and humidifier.

All electric home in a 13¢/kwh environment at 5852 heating degree days. ASHRAE winter design temperature for this Sierra Nevada 3500' mountain location is +10°F. Projected total cost in January is $170 or less for heat, hot water, lights, refrigeration, cooking, and laundry. That's $5.20/100sf/month.

Geo Monoflo Cottage
Two 360-ft vertical closed loops provide the geothermal source for a Bosch 2-stage 3-ton water-to-water heat pump, whose unbuffered output is fed directly into the home's original 2-branch loop of 10 cast iron radiators at 9 gpm by two Grundfos Alpha ECM circulators. Maximum radiative capacity is ~30,000 Btu/hr, at 125°F LLT, which is adequate for this 1400-sf stucco cottage. In practice, LLT and radiator temperatures rarely exceed 115° and 110°, respectively. A backup oil-fired boiler can be cut in on exceptionally cold nights or during power failures. A 4.6-kW rooftop solar array yields ~3,000 kWh per year, enough to cover most of the geosystem's power consumption. Inquiries: LFP87@verizon.net

Our Cool House
The Birth Place of the Web Energy Logger (Posting Since 2005)

Rather than building a traditional ''Energy-Hog'' home, or even a non-traditional Energy-Efficient home, our new home is a unique fusion of energy efficient techniques, and environmental sanity.

Our goal was to create a home that uses the sun, earth and water to create a pleasant living environment where we can enjoy the wildlife, and which also reduces our demands on non-sustainable resources.

Ground Source Geo Heating And Cooling
Fox Hill
Instrumentation Coming Soon.

By adding Solar PV (10 KW) to our roof and replacing the natural gas furnace (4 Ton) with a ground source heat pump, we stopped burning ancient hydrocarbons (fossil fuels) for our home (2011). When we transitioned to a plug-in hybrid EV(Volt) in 2012, we stopped buying gasoline for most of our transportation (i.e. local trips under 40 miles). It is possible to live comfortably without fire. That's cool.

(Haven't found the energy solution for our long distance travel yet - hydrogen hybrids?).

Five ton (single compressor - R410A) ClimateMaster water/water (vertical loop) heat pump (with HWG)in lakeside garage/apartment addition (completed 2016) to existing log house. Seven sub floor zones and 1 FirstCo air coil (heat/cool with 15 kW backup electric heat in 3 stages). HBX ECO - 0550 outdoor reset controller sets reservoir target according to outside temperature to match load and optimize COP (warmer OAT --> lower ELT --> less heat to envelope + higher COP). Main Reservoir: 72 Gal.; HWG reservoir: 36 Gal.

Electric load (addition, main house, boat storage shed) monitored by eGauge. Backup by Kohler 48 kW generator with load shedding.

Objective: Installer clearly did not understand much about heat pumps. Goal is to determine whether my fixes are such that the system is performing as it should. And keep an eye on my electric bill.

Danville, PA
2300 SF bi-level house, 1000 SF is a lower level with 2/3 below grade. Built in 1981, we purchased in 1991.

In 1998 had a Waterfurnace Premier2 installed. This 2.3 ton geothermal heat pump, with a desuperheater, replaced baseboard electric heat and a coal stove. The ground loop consists of two 175' deep vertical boreholes, with a 20% methanol mix, protected to 15º F. In 2016 we replaced the electric water heater with a GE 50 gallon hybrid tank.

Our overall goal, just trying to be smart with our energy usage.
