Dandelion Hopes to Broaden Geothermal's Appeal

Posted by Jay Egg

An interview with the CTO of Dandelion reveals a multi-faceted strategy for mainstreaming geothermal heating/cooling into homes.

Before I launch into my interview with James Quazi, let me provide some relevant background.

Back in 2014, I found myself at the Long Island Geothermal F1 DandelionAirImageConference, and a local politician shared his thoughts on the new addition to the local building codes for geothermal heating and cooling systems.  I was impressed. Later on Bob Wyman asked me if I would come to New York City for a presentation on geothermal before members of the NYC Council.

In Bob’s work with Google, he had been looking for the best way to help the geothermal industry take off the way the solar industry had in recent years. Sometime in 2015, I got a call from James Quazi  (formerly of Solar City) in San Francisco, asking me some hard questions about the industry. While I’ve always been keen to offer the best solution to challenges, I cautioned about going too far. I shared that when consideration a car’s MPG efficiency, going from 12 MPG to 15 MPG would save an average citizen in the US $700 per year. Going from 30MPG to 60 MPG would save about the same (See chart/figure—Image Credit EIA). The point is clear, and in the case of geothermal heat pumps (GHPs), it’s important to find the balance point of cost & efficiency.F2 GPM Example

The 2nd point that I made to James was the need for a low margin assembly-line approach.  I shared my experience with US Homes (acquired by Lennar in 2000) in the early 2000s.  I had a friend that worked as a superintendent, & he had persuaded me to install HVAC systems in new homes for them.  But the price-point was about half what I was willing to accept. He kept on me, sharing with me that if I followed “a recipe” of sorts that we would developed together, I would be selling hundreds of systems a year with little effort. This meant going from a gross profit margin of 40%+, to a margin of about 5%.  In other words, he was proposing that on a $10,000 HVAC system, I’d put $400 in the bank (if I made no mistakes).

I accepted reluctantly, and I lost money at first. But, after a few months, we worked out some kinks, and the operation became rather F3 Luxury Geo (2)streamlined. Over the next year I installed more than a thousand systems at an average profit of just $400.  I employed a lot of people that made great money, and I put almost a half million dollars in the bank; and it was truly running itself. I told James Quazi this story, sharing that we had to build a “machine”, and cut the margins, and then we were on our way.

The 3rd item I shared is that we need is to switch geothermal loops to an infrastructure, or utility level service. I pointed out that people living in neighborhoods or apartments certainly are not expected to generate their own electricity, drill water wells, or bury septic tanks. Heating & cooling should be part of the energy infrastructure of a community. Heating, air-conditioning, and domestic hot water systems consume more energy than anything else in homes and businesses.  Geothermal utility grids provide a heat source and sink eliminating the high up-front cost of geothermal loops.

Here's my recent Interview with James Quazi:

JE: Why did Dandelion decide to design/manufacture a new geothermal heat pump?F4 BobWyman James Quazi
JQ: Dandelion’s mission is to help enable the widespread adoption of home geothermal. To do this, we needed to (1) manufacture a durable and high performance heat pump at a reasonable price, and (2) collect data and intelligence on system performance.

On the manufacturing side, we partnered with AAON to design and produce the Dandelion Air. Both Dandelion and AAON share the belief that automation in manufacturing reduces cost and increases durability. We also believe that time spent in the design phase solves lots of problems down the road (e.g. component layout for ease of servicing, etc). Lastly, both organizations also believe that sophistication should be held in a monitoring and control layer, rather than in the components.

The Dandelion Air is special because of Dandelion Monitoring. Dandelion Monitoring enables us to do a number things, including: 1. Automatically commission systems at the time of installation, which allows us to make sure each install job was done correctly, 2. Collect high-quality data on systems on an ongoing basis, 3. Monitor faults and troubleshoot remotely. This data will also help financiers get comfortable with financing home geothermal. With new capital, we can unlock more affordable ways for homeowners to get geothermal and enable widespread adoption.

JE: What do you think the impact will be on the geothermal heating and cooling industry in New York and beyond?

JQ: Geothermal is poised for explosive growth in New York, as the state and the utilities are putting programs in place to incentivize homeowners to switch over from fossil [fuel] heating. These incentives combined with the recently reinstated federal tax credit have created a highly favorable environment for geo. In this context, we aspire for the Dandelion Air to set a standard for monitoring, cost and convenience. To fully take advantage of the opportunity in New York and beyond, we all collectively need to ensure that high quality systems are being installed, that the performance of those systems meets or exceeds expectations, and that we can quantify that performance. JE: Can contractors buy the Dandelion Air? What is required (generally) to become part of the Dandelion Geothermal effort?

JQ: Due to demand and our relatively small team, we are only able to sell Dandelion Air to contractors that have partnered with Dandelion. Contractors who wish to become part of the Dandelion geothermal effort should fill out the following form on our website: https://dandelionenergy.com/installers/. We look forward to hearing from installers everywhere!

JE: Can you point to a particular point at which your team decided this step (design/manufacture of the Dandelion Air) would be beneficial?

JQ: When the founding Dandelion team was still at Google, where the project originated, we conducted a survey of geothermal heat pumps on the market. This involved performance testing, tear down analysis, and component costing. The realization at the end of this effort was that none had all the required features at a price point that was feasible for everyday homeowners. We then started a search for a manufacturing partner who shares our vision for bringing home geothermal into the mainstream. This is exactly what we found in AAON.

JE: Anything else you'd like to share?

JQ: We are incredibly excited about the opportunity for the industry as a whole, not just Dandelion. We see many contributing factors coming together that will propel the industry into the mainstream.

On a more personal note, I’d like to thank you (Jay Egg) for your influence on the way the Dandelion Air was developed. We spoke a few years ago when Dandelion was a very early stage project at Google. At that time you encouraged us to look for durable and cost effective solutions and resist the urge to fetishize components and features. That is exactly where we ended up. Thank you.
