Eco Luxury is the new standard for consumers that want to support a sustainable lifestyle but don’e own their own property yet. Geothermal is a thoughtful way to use renewable energy elements to help save money, retain tenants, and overall cost competitiveness for developers.
Colorado is a great state to start a small business in. With low income-tax rates, low unemployment, and great entrepreneurial energy Colorado frequently ranks high in national rankings for doing business. Which are all fantastic to start a green business like ours. According to the Colorado Energy Office, Colorado ranked 6th in marketed natural gas and has the third largest natural gas reserves in the country. And according to the Energy Information Administration, Colorado ties for 45th for the average price of natural gas (per 1,000 cubic feet)- meaning it tied Alaska, Connecticut, New Hampshire, Oklahoma and Washington as having some of the most inexpensive natural gas prices in the country. Choose Energy reported that in June, Colorado ranked 7th cheapest in natural gas rates in the country. Doesn’t sound great for selling geothermal does it? I disagree and here is why:
One of the biggest comments we get when a client inquires with us about installing geothermal is that they want to reduce their carbon footprint. Younger generations are interested in reducing their impact on our planet, and are educating themselves on ways to do it. From electric vehicles to solar panels to recycling to geothermal, they are choosing to make a conscious effort to make the planet better for its future inhabitants. They want to reduce their reliance on fossil fuels and are figuring out that decarbonization is important to them. Geothermal allows them to reduce their carbon footprint and propel them towards the changes they want to make.
For other customers, installing a geothermal system is about reducing their utility bill and keeping their future monthly expenses down. As people are aging into their homes they want a system that will last, be comfortable and low maintenance, and save them money. Even with inexpensive natural gas prices in Colorado, many of our customers are still seeing a pay back of 5-8 years when they replace their dated furnace and air conditioner with a geothermal system. Federal tax credits and utility rebates don’t hurt either. One of our client’s called us the other day to tell us how excited he was to be getting a nice check back from his utility company because of his new geothermal system. The cost of his retrofit geothermal system after tax credits and utility rebates was comparable to what he would have paid for total replacement of a less efficient furnace and air conditioner.
As more and more municipalities set Clean Energy and Net Zero Carbon goals, geothermal presents utility companies, homeowners, developers, builders, and investors a means to meet high performing, sustainable development. For example in Boulder county, they have proposed a goal to require all new residential construction to be Zero Net Energy by 2022. More homeowners are educating themselves and realizing that geothermal is a great way to meet these needs. In the next several weeks we will be installing 9 geothermal systems in the Boulder area. Yet just driving to Boulder we probably will pass twenty-some drill rigs, work over rigs or wells in the 25 miles between us- reminding us that Colorado is still a top producer of natural gas. But in my opinion, this is starting to change.
Our state is amply supplied with both fossil fuel and renewable energy resources. And as a green business owner and geothermal industry defender the impact of cheap fossil fuels in our state keeps us advancing our installation game and best practices. We have had to build more compact, efficient and safe equipment and streamline our processes. Maximizing efficient drilling operations helps us keep costs down and present quality, affordable geothermal systems to our customers. We are on a mission to make geothermal accessible and economically viable to all homeowners. So, while natural gas is abundant and cheap in our state, we are upbeat to see homeowners educating themselves about a technology that can check all their boxes. Energy efficient, decreased carbon footprint, save money, safety, comfort, reliable, aesthetically pleasing, security, and no weather damage, corrosion or vandalism. We may not be the biggest and aren’t taking millions of investor dollars into our company, but we are bringing affordable geothermal to more homeowners and simplifying the process with our modern installation practices. We are a small, family owned company that has been providing quality geothermal systems for over 15 years based on our innovative approach and streamlined operation and will continue to provide affordable geothermal solutions to our customers.
Let’s be honest, there are more than 4 reasons to install the best heating and cooling system available, according to the EPA, but how many do you need when this system can give you piece of mind, comfort, and cost savings?
The perks of installing a geothermal system are endless, but lets start with these 4:
4. Geothermal is Clean & Invisible. What the……you ask? A great benefit of geothermal is it is clean, and you don’t even know it’s there. Clean, as in there is no onsite combustion of fossil fuel to heat your home. You may have a natural gas furnace that emits carbon monoxide, carbon dioxide, methane, volatile organic compounds as well as other nitrous oxides but geothermal does not. And invisible as in there is no loud, ugly, outside air conditioner ruining your beautiful outside aesthetics because inside, the (GSHP) ground source heat pump is operating quietly and efficiently. You know that loud hum you hear when your neighbor’s 12-year-old air conditioner kicks in while are enjoying the fruits of your labor in the backyard. It makes a difference!
3. Geothermal gives you comfortable heating, cooling, and can even pre-heat your domestic hot water heater! Simply put, in the winter warmth is drawn from the ground through a loop carrying a water solution to a heat pump (GSHP) inside your home. The GSHP concentrates the Earth’s thermal energy and transfers it to air circulated through duct work or radiant heat in flooring. In the summer, the process is reversed and heat is extracted from the air inside your home and transferred back to the ground. As an added bonus, the waste heat from the compressor can be used to preheat water for your hot water heater! That’s comfort and cost savings!
2. Did you know that having solar or geothermal is not an either/or scenario but are actually a great compliment to each other? As you already know, solar power is using the sun to create power and geothermal systems can be a great compliment to them. A geothermal system can save you money because for every unit of energy used to power the system, 3-5 units are supplied as heat. Where a fossil fuel furnace may be 78-80% efficient, a geothermal heat pump is about 400% efficient! So you can power your home and heat pump with the sun and heat and cool it with the bountiful, stored energy in your yard! Planned correctly, you can get to net zero, where the total amount of energy used by hour home on an annual basis is roughly equal to the amount of renewable energy created on site. Check out more about that here!
1. Geothermal will save you money! Until December 31, 2019, the federal government is offering renewable energy tax credits for geothermal heating and cooling systems. The credit is a 30% tax savings for installations through the end of December 2019. It starts to decrease in 2020. This tax credit coupled with energy efficient operation of a geothermal system yield big savings for homeowners! Also, utility companies are offering exclusive rebates for installing energy efficient equipment. For example, in Colorado, United Power and Tri-State G & T are offering $200/ton and $500/ton respectively! An average 3000 square foot house might have a 4-ton ground-source geothermal system in it, yielding a rebate of $2800! Add in the federal tax credit and homeowners are seeing great savings that quickly offset the initial difference in purchase price.
The perks of having a geothermal system are abundant and now is a great time to get an energy efficient, environmentally friendly, ecoluxury geothermal system for a price close to a conventional system!

We are often asked what the geothermal installation process is like and if it’s messy. YES! A resounding yes is the answer to this question!! Homeowners are surprised when they see how much equipment rolls up in front of their home, but are even more surprised at our efficiency and streamlined process and how quickly we can be in and out. There is a lot that goes into installing geothermal- a drill, skid steers, a grout plant, an air compressor, stacks of drilling rods, an excavator, loops, holding tanks, hoses, water, I could go on and on. We invest in our company to make sure we are mastering leading technology as we pride ourselves on the quality of services we commit to our clients. Our process and equipment have been designed to ensure safety of our employees and a quality and efficient installation for our clients.
At Colorado Geothermal Drilling we are known for specialized installation in compact spaces. Now imagine- we have to drill three 300-foot holes in a front yard like the picture here. That’s nearly 1 football field per borehole! The good news is- a job like this will usually take us less than a week from start to finish.
So the process is going to look something like this: Equipment is brought in with several trailers and trucks. Our crew will strategically set up equipment and prepare for drilling.
We will locate where the loops will be installed to make sure we stay clear of gas lines, water lines, electrical lines, fiber optic, sewer, and sprinklers which will impact our drilling locations. Keep in mind we have these located ahead of time because we want to make sure our crew stays safe. However, it is not unusual for a sprinkler line to be cut as these typically are easy to fix and often transverse throughout a yard.
After loops are installed we must excavate around the loops and dig a trench to manifold all of the loops together to bring into your home and to your geothermal heat pump. High density polyethylene pipe (HDPE) is used and is heat fused together to form joints stronger than the pipe itself.
Once all loops are fused we will bury everything and bring your yard back to grade. We are not landscapers so we don’t lay sod, rock, or plant trees. Most homeowners either do it themselves or hire a landscaper to come back in and lay sod or take the opportunity to update their landscape. After the project is finished most people have no idea that geothermal was just installed and that their neighbor just became the next Genius Geothermal Homeowner!
One of the best things about your geothermal system, besides the energy efficient heating and cooling, is that you no longer have an outside air conditioner making noise and ruining your outdoor aesthetics. Your close proximity neighbors will notice how quiet it is and you will be enjoying the quiet sounds of nature, as it was intended.
Living with a geothermal system is an exceptionally quiet, comfortable, energy efficient, and environmentally friendly experience. If you don’t already know the benefits- I will take this chance to share them with you again:
Geothermal provides enhanced comfort, improved indoor air quality, natural aesthetics (no loud ugly outdoor equipment), safe heating because there is no onsite combustion of fossil fuels, no worries about carbon monoxide, fuel/gas leaks or spills, or fumes, reduced noise, minimal maintenance, no weather damage or vandalism, reduced greenhouse gas emissions, reliable, ‘green’ technology recognized by LEED.
Colorado Geothermal Drilling works with homeowners, builders, HVAC contractors and designers to provide the best geothermal design and installation to meet the client’s needs.

A rudimentary explanation and suggestions on how to live greener and cleaner from an Average Green Energy Enthusiast, Geothermal Gossiper and Carbon Footprint Tiptoer
With media coverage of popular buzz words like ‘climate change’, ‘be green’, ‘environmentally friendly’, ‘carbon neutral’, etc. it can be difficult to manage and comprehend the ever-changing renewable energy mantra.
Having a Net Zero home is increasing in popularity as more people want to reduce their reliance on fossil fuels and the grid and build sustainable, efficient homes. The definition of net zero means “the total amount of energy used by the building on an annual basis is roughly equal to the amount of renewable energy created on site”, according to the World Green Building Council.
One of the first things to consider if this is attainable for you is to evaluate your utility energy usage and determine effective ways to reduce it. This part is often overlooked by consumers since residential solar and wind are marketed so heavily to easily and quickly turn your home into a clean energy burning machine. While these renewables will absolutely offset you reliance on the electrical grid, it is also important to examine your current energy usage and determine ways to decrease it.
“After all, decreasing your overall energy usage saves you money and can help control the size of the renewable system you want to install”
Two thirds of the average home’s energy bills come from heating, cooling, and hot water. You are spending a lot of money to heat and cool your home and heat your hot water heater! Do you have the most efficient system installed? A geothermal system is the most energy efficient heating and cooling system there is. Check out this video for a quick explanation here. It uses heat from the earth, by way of geothermal loops to heat and cool your home. Simply put, in the winter warmth is drawn from the earth through a loop carrying a water solution to a heat pump inside the home. The heat pump concentrates the earth’s thermal energy and transfers it to air circulated through duct work or to radiant heat in flooring. In the summer, the process is reversed and heat is extracted from the air inside your home and transferred to the big heat sink in your yard (the earth) by way of the geothermal loops. As an added bonus, the waste heat from the compressor can be used to heat water for bathing, cooking, washing, etc. Sounds fantastic doesn’t it? There’s more!
Another great benefit of geothermal is it is clean and you don’t even know it’s there! Clean, as in there is no onsite combustion of fossil fuels in your home! And invisible as in there is no loud, ugly, outside air conditioner ruining your outside aesthetics in the summer and inside, the heat pump is about the size of a furnace yet operates quietly and efficiently. So you get quiet, comfortable, safe, efficient, environmentally friendly because you are reducing your carbon footprint, AND saving money. A geothermal heat pump can save you money because for every unit of energy used to power the system, 3-4.5 units are supplied as heat. Where as a fossil fuel furnace may be 78-90% efficient, a geothermal heat pump is about 400 percent efficient!
To continue to plan a comfortable, energy-efficient home and decrease your overall energy usage try installing LED lights and Energy Star rated appliances. Take a good look at how you live in your home. Focus on what you really you use and how to make it as efficient as possible. For those of you that love your gas stove, I challenge you to try an electric induction cook top. Every bit as efficient as gas but safer! You can live with out natural gas hooked up to your home!
Installing energy efficient doors and windows, and adding adequate insulation in your exterior walls and roof also can keep your utility bills down. You may want to also evaluate passive solar building design where you look at windows, walls, and floors and their ability to collect, store, reflect and distribute solar energy in the form of heat in winter and reject solar heat in the summer. This too will aid you in achieving a net zero home and decrease the overall size of your renewable system(s) as well as your impact on Mother Nature.
Eight years ago we retrofitted our 4773 square foot (including 75% finished basement) home in suburban Denver. The home was built in 2000 with conventional construction, nothing over the top as far as insulation, windows, and efficiency go.
Shortly after moving in we had a blower door test done and learned about where we had insulation inefficiencies throughout the home. We added more insulation to the attic taking it from an R-30 to R-60. The basement was unfinished at the time so we made sure it was adequately insulated as well and increased the minimal R-13 insulation to a R-21. We also had all ductwork sealed which reduced air leakage from 20% to less than 3%.
For the geothermal residential retrofit we drilled eight 300-foot loops on the North side of the home. We planned ahead and added additional loops for a future 1990 square foot metal shop we were going to build in the next few years. All eight loops were manifolded into a common header and connected to the 5-ton geothermal water to air heat pump in the home as well as a 5-ton geothermal water to water heat pump for the shop. The pumping system utilizes high efficiency ECM pumps that save approximately 70% of the energy typically used with a common pumping system.
The shop was built with radiant tubing in 5 inches of concrete all spaced 6 inches apart and batt insulation in the walls and ceiling at R-25. There is a total of just under 4000 feet of 1/2 inch pex tubing for the radiant floor heating system. Sixteen loops approximately 250 feet long each made up the radiant floor which allowed the geothermal system to operate at a lower temperature for heating and reduces heating costs in the worst months of the winter. The shop averages about $20-30 per month while the house averages about $60 a month for heating and cooling. The only natural gas used in the home is for 2 gas fireplaces, used for aesthetics only.
The comfort level and overall aesthetics of the geothermal system are what we as homeowners love the most. The three level home can easily be warmed up or cooled down very quickly, is quiet and extremely comfortable. And with lots of outdoor family time, the loud, outside air conditioning condenser is not missed! Installing the most energy efficient heating and cooling system can be done in all types construction. Retrofits are very successful and will save the homeowners money when designed and installed appropriately.

Geothermal has been a big part of our life for nearly 20 years. Who would have thought that the little barn in Northwest Iowa that we hosted our wedding reception at, and used geothermal to heat and cool it, would play such an integral roll in our lives? I mean, who spends the bulk of the visit to their wedding reception venue hanging out in the mechanical room talking to the owner about how geothermal works and how it’ll keep this old barn with 150 people in it cool on a hot July evening in steamy, humid Iowa?
This guy. This Mechanical Engineer I met at Iowa State University and married 18 years ago. Little did we know that the geothermal system in that old barn set the stage for our passion, mission, and goals of building a small family geothermal business in the Rocky Mountains.
After a few years designing HVAC and geothermal systems Dan knew that he wanted to get out of the office and back to designing, building, and operating equipment. He loves processes and coming up with ways to improve geothermal installation to make it more safe, efficient and streamlined. His engineering degree came in handy when designing aspects of his drilling equipment. Dan’s engineering knowledge mixed with his drill operating experience has made him an unusual and rare occurrence in the geothermal industry. He frequently works with architects, engineers, designers, HVAC contractors, builders and clients to help guide them to the geothermal system most appropriate for their heating and cooling needs. Dan’s comprehensive understanding of geothermal design and installation, our specially designed equipment and our personnel allow us to successfully and repeatedly complete numerous geothermal jobs.
Over the years Colorado Geothermal Drilling has successfully designed and installed over 500 geothermal projects in Colorado and surrounding states. Our set-up is unique as we are able to access compact areas with our equipment, setting us apart from other drilling operations. With our vast knowledge of geothermal design and installation we can provide customers with valuable information, answering any questions, and providing the best energy efficient system to fit the clients’ needs. Colorado Geothermal Drilling strives to master leading edge technology and pride ourselves on the quality of services we commit to our clients. In fact, we have installed geothermal systems for our competitors.
We don’t just talk the talk, we walk the walk too. We truly believe geothermal is the most energy efficient heating and cooling system available and have put it in our homes as well. Within 10 days of moving into our current house we set up the drilling equipment and installed our system. We have plans to install it in rental properties Kari owns and manages as well. What some see as scary upfront costs, we see as a great way to manage utility bills for many years to come. Installing geothermal in rental properties is a great way to save money, reduce our carbon footprint, and have a comfortable and long lasting system with very little maintenance to worry about. We can’t wait to get rid of the big propane tank on our next property!
Over the years we’ve done some really great projects. From wineries to fire departments, nature centers, military bases, art galleries and net zero homes. Educating people on the outstanding benefits of geothermal is one of things we love most to do and I hope to continue sharing these with people in the future. Like I’ve said before, one of the greatest things about geothermal is you can’t see it, but because of that so many people don’t know about it and how fantastic it is! Now is the time to really get the word out on geothermal!
