WaterFurnace Envision and Intellizone control

Pear Blossom #1
Private Residence
4200 sq ft, Meridian Idaho
Retrofit: Removed existing (2) 80% propane furnaces & (2) 10 SEER A/C units

These homeowners experienced propane bills in excess of $700 per month prior to contacting us for a geothermal heat pump. Both propane furnaces were removed and replaced with a single WaterFurnace Envision and Intellizone control. We used the existing domestic water well for supply water, and drilled a separate discharge well which the owners will share with their neighbors system. The discharge well allows the water to be returned directly back into the ground.


WaterFurnace Synergy 3D unit and Intellizone control

Pear Blossom #2
Private Residence 3400 sq ft,
Meridian Idaho
Retrofit: Removed existing (2) 80% propane furnaces & (2) 10 SEER A/C units

Existing propane systems were replaced with a WaterFurnace Synergy 3D unit and Intellizone control. The Synergy 3D unit will provide heating, A/C, domestic hot water, as well as hot water for radiant floor heat. The Intellizone system allows for independent temperature control both upstairs and down. As with almost all (of our) open loop systems, no back-up electric heat elements are installed. This home is heated entirely with the geothermal heat pump at 427% efficient (as measured at start-up).


Open loop WaterFurnace Envision system

Pear Blossom #3
Private Residence 3500 sq ft,
Meridian Idaho
Retrofit: Removed existing (2) 80% propane furnaces & (2) 10 SEER A/C units

Open loop WaterFurnace Envision system. Again with the Intellizone multi-zone control. All the Envision systems feature R410A earth friendly refrigerant, variable speed blower motors, and 2-stage compressor operation. The system is extremely quiet and makes about as much noise as a standard refrigerator. As with all open loop systems, we install components in the plumbing package to ensure any water noise is kept to a minimum. This is significant for anyone considering an open loop. With well pressures at 60psi, the water noise can be much louder than the heat pump if not installed correctly.


Water Furnace Envision

Frozen Dog
Private Residence 2200 sq ft, Emmett Idaho
Retrofit: Removed existing 80% propane furnace and A/C

3 Ton WaterFurnace Envision. This homeowner installed an underground drainfield based on our input. Supply water is again from the domestic well (open loop). After running through the WaterFurnace, the water is injected into the drainfield ~ 5ft below the surface where it drains back into the ground. This is an effective and inexpensive way to discharge water with an open loop system. Performance depends on soil type in the area.

3 Ton WaterFurnace Envision system

Black Canyon
Private Residence
2200 sq ft, Emmett Idaho
New construction

3 Ton WaterFurnace Envision system. Ground water in this Emmett area is abundant and close to the surface which is excellent for open loop systems. This homeowner was able to discharge into a warm water slough on his property and save money in initial install costs. As with all our systems, the Hot Water Generator (HWG) is included. The HWG connects directly to a stand alone water heater. Whenever the unit is either heating or cooling the home, it is also injecting heat into the water heater to provide additional savings. This energy is absolutely free in the summer (heat is a by-product in cooling mode). After a month the customer said the same thing we’ve heard many times…”For some reason we’re keeping our house 2 degrees cooler than in the past? It just feels warmer and we’re comfortable there.” The system doesn’t dry the air like gas furnaces and provides more even heat due to longer run cycles. This makes the home feel warmer at the same temperature on the T-stat.

Retrofit: Removed existing 80% propane furnace and A/C

Replacing propane systems with a Geothermal Heat Pump has been a huge part of our business. The payback for a geothermal system when compared to the cost of propane is generally 2 years or less! The 30% Federal tax credit has helped homeowners even more. Homeowners receive a tax credit equal to 30% of the complete system install cost (with no cap). This along with the Idaho Power Incentive check ($1,000 written directly to the owners) basically cuts the cost of a system in half! We installed an underground drain field on this system as well.


Closed Loop Projects
Vertical Closed Loop – Donnelly

Cascade Lake – Vertical Closed Loop
Private Residence
5000 sq ft, Donnelly Idaho
New Construction – 2 geoexchange systems connected to common closed loop

This home is located right on Cascade Lake. Space restrictions didn’t allow for a pit with horizontal slinky loops. Instead a driller was employed to drill six vertical bore holes. Loop piping was then installed and grouted back to the surface. We fused the loops together into a header system that would ensure even flow through all six loops and brought the headers into the home. More below

Inside we installed two circulators, isolation valves, and connected to the water source heat pumps. As with all closed loop systems, the piping was then purged of air, freeze protected, and pressurized.

Idaho Geothermal Horizontal Bore – Ground Loops

South Slope
Private Residence
5800 sq ft, Emmett Idaho
New Construction

We installed two Carrier ground loop heat pumps in this large home. Pictured here is the horizontal bore machine used to install the loop piping. Instead of digging a pit for slinky loops, we decided to experiment with a horizontal bore machine. This machine can bore a 4” hole horizontally at ~10ft deep. After each 200ft run, the machine can turn the drill head back toward the surface, attach to our loop pipe, and pull it back into the bore hole. More below

Two pipes are pulled into the bore hole with a “U” bend fused onto the ends. The loop water flows out and back each bore hole absorbing heat from the earth and delivering it to the heat pump. Obvious advantage is saving landscaping or install loops under existing driveway, etc.

Idaho Geothermal Horizontal Slinky Loop

Private Residence 2200 sq ft,
Gooding Idaho
New Construction

This home employs a Climate Master geoexchange system and 4 Ton loop field. Also installed is an HRV (Heat Recovery Ventilator) which provides fresh air to the home while conserving energy. Exterior walls in this house are built from Structural Insulated Panels (SIP). The SIP’s provide excellent insulation and can be easily sealed to combat heat loss due to infiltration. More below

The result was an extremely tight and efficient home. This owner enjoys total energy bills that max out at ~$60 per month in the coldest part of winter. The pit is an odd shape because we encountered rock during excavation and had to change the lay-out.


Idaho Geothermal Slinky Loop Sweet Idaho

We were selected as the geothermal contractor to install the earth loop for this custom home in Sweet Idaho. It connects to two water-source heat pumps to provide heating, A/C, and all domestic hot water


Idaho Geothermal Ground Loop Emmett, Idaho

Private Residence 3800 sq ft, Emmett Idaho
Retrofit – Removed propane furnace, electric furnace, and two A/C units

Installing this ground loop was challenging due to the sloped hillside. You can see the soil contained a large amount of river rock which made for a tedious backfill process as well. We are often able to remove two separate heating systems in a home, connect the ductwork together, and install a single WaterFurnace geo unit. The Intellizone control plays a huge part in the ability to do this. This home is experiencing much less than half the heating bill from winters past.


Idaho Geothermal New Construction 11,000 SF Boise Idaho

Private Residence 7400 sq ft Residence, 3300 sq ft Woodshop, Office, Apartment Space
New Construction

This horizontal closed loop serves over 10,000 sq ft of heated space, domestic hot water, radiant floor, and hydronic air handlers. We installed a single WaterFurnace Envision to heat the 7400 sq ft home with four separate heating zones. A WaterFurnace E-Series water-to-water heat pump provides hot water which will heat the detached buildings and radiant floors. Both Geothermal Heat Pumps are connected to the same loopfield shown here. More below

This home is insulated with closed cell spray foam which significantly reduces the heating loads. The system maintained 72 degrees throughout the house in December 2009. Based on the total amp draw (and $.072/KWHr), the system could run 24/7 (on high speed) for an entire month and the power bill would never exceed $260 for heating. Obviously it won’t run constantly, and the owner will enjoy even lower heating bills for this very large home.


Idaho Geothermal Geothermal Heating Caldwell, Idaho

Private Residence 4200 sq ft,
Caldwell Idaho
New Construction

6 Ton water source heat pump and closed loop system. Zone controls allow three independent heating areas. The horizontal slinky loop configuration continues to be the most cost effective install in this area. Soil conditions and the heat load of the house always dictate the size of the loopfield. Depth is also a big factor. More below

We could install all our loopfields at a depth of 1ft, but it would be the size of a football field. The deeper you dig, the less pipe you need. Goal is to select the depth and loop length that is most cost effective to install. This customer keeps their home at 72 degrees 24/7 during the winter.


Idaho Geothermal Horizontal Closed Loop – Mountain Home Idaho

3,800 sqft new construction –
Mountain Home Idaho

The presence of lava rock will sometimes dictate the shape of your ground loop pit or trench. It certainly is not a show stopper though. We simply trucked in some clean top soil to bed our loop pipe. Once the slinky loops are covered, you can then backfill with the native soil / rock and be confident that your pipe is safe. This loop is serving a 5 Ton WaterFurnace Envision and a 3,800 sqft new home.
