|The WEL monitors our vacation / future retirement log home in the beautiful mountains of SW Colorado. I installed a 3 ton geothermal water to water system to provide hot water for the in-floor heating used in the garage and basement floors, along with a 5 ton geothermal water to air system that provides hot and cold forced air to the main and upper floors of the house.|
|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>
|This is our second RE home. The first was passive solar. This one is a Cape Cod. The Waterfurnace E-Series is doing a good job. Spend time to get a good installer, we didn't. Evacuated tubes are the best investment that we have made. 175 tubes on the roof heat a 650 gallon tank. PV is fun to watch, but way too expensive to get a payback. Connecticut needs to force the Grid to pay us $0.50/KW, instead of the wholesale rate of $0.11.|
Our total investment of $50K will take about fifteen years to achieve some balance. But, that was not our goal. Our goal was to show that it could be done today.

Currently there is just data with no graphics. Honestly there probably will never be. Expressions are still a work in progress.
Rusty Nail Workshop
|This WEL is being used to monitor the operation of a typical family in a split-level home. For heat, the house has a natural gas forced air furnace with an electric heat pump, both installed in 2009. It also has an air conditioner (15.5 SEER, installed 2009). Hot water is provided by a tankless water heater. A 2.1 kW photovoltaic solar array was installed in August of 2012. Typical output of the PV system is about 1800 kW (max).|
|This is a 2500 sf average constructed 20 year old home which is heated/cooled with a ground source heat pump (GSHP). The 4-ton heat pump is a H050 Hydron Module using a non-pressurized closed ground loop. The ground loop consist of four 500' high-density polyethylene (HDPE) thermoplastic pipes. The pipes are buried in four 100' long trenches at an average depth of six feet coiled in a horizontal slinky loop configuration.|
Bob & Kathy's House
|Our Victorian style all electric home was built in 1986 using available insulating materials and HVAC technologies that existed at the time of construction. Specifically, the home was insulated using 2x6 walls with fiberglass batt insulation with 1 inch double foil faced PIR (polyisocyanurate) foil taped panels placed on the interior walls, covered with sheet rock (R28). The attic space was insulated with blown in fiberglass (R40) with a polyethylene vapor barrier. We also used triple glazed high R windows, inset and insulated the band joists for both the first and second floor, and confined the forced air duct work, plumbing, and electrical to interior walls and used low profile surface outlet boxes at the base board to keep the perimeter walls intact.|
The original A-A heat pump continues to serve us well for both heating and A/C. A number of years ago we added a pellet stove that we use when the outside temperatures drop. The pellet stove can easily heat the entire house even when the outside temperatures are 0 F (we turn the heat pump off).
I'm currently investigating the installation of a geothermal W-A heat pump for the future.
|Solar / Wind / Geo Thermal system|
|This is a 3 bedroom 1800sq' chalet style home. (Its 2100sq' when calculating heat loss due to high cathedral ceilings. It is in-floor heat throughout. No air handlers and no cooling (yet). Heat source is a 3 ton water to water heat pump (Nordic by Maritime Geothermal) coupled to a ground loop of 1800' (3 - 600' loops). Also has a de-superheater for domestic hot water. The house has a lot of solar gain and quite sheltered from the north wind. I've been monitoring it manually for a year, now with Phil's equipment I can do it automatically and remotely.|
Mountain Top House
|Our house is new construction built in 2005. About 6,500 sq ft. We use two Geothermal Heat Pumps - one water to air for A/C and second floor heat and one water to water for radiant heat to first floor, second floor master bedroom/bath, basement and garage. The water to water unit also preheats the domestic hot water and is supplemented by a Bosch tankless propane water heater. We also have a hot water recirculation system currently set up with a timer and thermostat.|
As you can see from my graphic the monitoring system is still under construction and I will continue to add sensors, etc. (So much fun -driving my wife crazy!)

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 it 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 oversizing...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.

The Energy Efficient Barry Household
|The Barry house has been an ongoing experiment in renovating a 1968 bungalow into an energy efficient home for a sustainable future. We continue to monitor all electricity usage, heat loss and renewable energy gains. The house has passive solar design, insulation to R-20 or greater in the walls, R-65 or greater in the attic, outside and inside foundation insulation. An air source heat pump is used for heating with extra heat on really cold days from a high efficiency Opel wood insert fireplace. Solar thermal is used for hot water heating and a drain water heat recovery system is in place to recapture drain water heating. Our family of 6 attempts to use hot water on sunny days and match our usage to production to optimize efficiency. We also monitor all electricity usage through a TED 5000. The whole house is an ongoing R&D experiment in validating true cost efficiencies and value from renewable energy and from changing patterns of usage. So far, we have validated that this is the right thing for all of us to be doing and that payback comes in many more ways than simple investment returns. If you are thinking of doing this - do it! And if you want help, just ask!|

Freedom Won Solar Heater
|This solar water heater uses the Freedom Won patented technology and provided 74% of the heat energy this family used in 2011. It is fully automatic, off-grid and includes an automatic heat dissipater. The features include:|
- Three twenty-tube evacuated collectors.
- An integrated PV panel mounted on the thermal collector that energizes the variable speed circulating pump
- An automatic heat dissipater that is controlled by a thermostatic valve configured to limit the solar fluid to 200F.
- An internal-coil 80 gallon stainless tank preheats potable water with solar energy which then flows into a conventional gas water heater for additinal heating if necessary.
- The array is wall-mounted on a south-facing brick chimney that receives good exposure most of the year although it is shaded by the neighbouring home in the winter.
- There is no electronic controller.
- It uses 50% propylene glycol, 50% water for the working fluid.
It works great - when the sun shines it heats water. There is nothing for the homeowner to adjust, no annual maintenance and no reliance on grid electricity. It will not overheat or freeze-up; it just works.

Niagara Escarpment Geothermal
|This architecturally designed house sits right on the Niagara Escarpment with stunning views over Lake Ontario. The oil fired boiler was replaced in the fall of 2010 with a state of the art geothermal system designed and built by Buffalo Geothermal. The vertical heatexchanger (installed by Nothnagle Drilling) consists of 2 boreholes, each 400ft deep into the bedrock of the Niagara Escarpment. The Hydron Revolution HWT 070 2-stage water-water heatpump provides the entire heat load for the radiant floors as well as year around domestic hot water.|

Melrose Solar Thermal
|A solar thermal system that serves domestic hot water and space heating needs.|
|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).|
|I have been a fan of the WEL for sometime now. We recently had a Geothermal heating/cooling system installed and I wanted a way to better monitor performance.|
5/2012 We have just installed a 7.65 KW PV system. We are hoping for this to cover 70% of our kwh usage throughout the year.

|We have a 4-ton 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. |
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.
We have been researching the WEL for awhile. We are hoping to get a better understanding of how our system is performing and monitor in greater detail our temperature sensor data and monthly heating and cooling costs.

|We have 3kW of PV that supplies all our electricity (plus ~10%), and solar water heating by butlersunsolutions.com. It's a two-tank system with two 40-gallon tanks connected so they can convect naturally to heat the upper (pilotless, gas-fired) tank. The bottom tank has the BSSI solar wand heat exchanger that heats the tank from a 32 sq.ft. collector on the roof.|
The gas water heater is on a timer that only allows it to fire up 5pm-6pm, and 3am-4am. So when we use water in the morning, the solar system has a chance to reheat it before the gas kicks in, and if the tank is not still warm after the evening usage, the gas comes on in the early AM so we have hot water in the morning. This appears to reduce the gas operation by quite a bit, over and above the savings from not having a pilot light.
In mid-2011, I installed a BSSI DeltaT+ controller that turns off the PV-powered pump if the collector is not warm enough. This avoids almost all energy losses from circulation in the morning or evening when the collector is cold.
23 May 2012: I installed a sensor so I can now measure and record output from the solar electric (PV) system as well as the solar hot water system. The sensor cost about $10 in parts.

|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.

We are Andrew, Julien, Josh and Kevin and we are Team 3 of Dalhousie's mechanical engineering design class! We are designing a completely autonomous system which will use the output power of several solar panels to heat domestic hot water. When the water is up to temperature, the excess power will be used to charge a bank of batteries. In theory, with PV panels, every kWh of energy can be used.

|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.
