These are real pages from the book. The table of contents is the full one: 8 parts and 60 topics.
You're on a new site. The rig is parked, there's a water well near the property line, and you have to stake the first bore. How far does it have to be from that well?
The setback rules are in the manual, spread across paragraphs. The distances change with loop depth, with the type of well and with the state. You read it last night, and by morning it's gone.
In the book, site layout is one drawing: the house, the well, the property line and the bores, with the distances marked on it. Minnesota example: 35 ft from a water well for loops deeper than 15 ft, 10 ft if shallower. There's also a note to check your own state's code.
The rest of the job works the same way: the ground in cross-section, HDPE fusion, the 100 psi pressure test, the three jobs grout does, the trench back to the house. Each one has its own page.
You look at the layout, see the distances and stake the bore. No digging back through the manual.
The system, geology, drilling the bore, HDPE and fusion, pressure testing and insertion, grouting, headers and purging, and exam review: 64 pages, all illustrated.
Think of it this way:
The loop is fused and on the reel. Before it goes down the bore, you have to test it. What pressure, and for how long?
You open the page on testing and see the U-bend drawn with the gauge on it: at least 100 psi for one hour, before insertion, with the code it comes from (Uniform Mechanical Code) and a note to check what your state requires.
Same with the ground in cross-section, setbacks on site, why HDPE is fused and not glued, the three jobs of grout and the trench back to the house: each one has its own page.
Geothermal Loop Driller Illustrated is 64 pages in 8 parts, one topic per page, all drawn, with a full exam review and field checklists at the end.
What you see drawn, you don't have to memorize.
What a vertical closed loop does, how it compares with open and horizontal loops, the whole job in one sequence, who does what, heat transfer basics, and codes, permits and certification.
The ground in cross-section, unconsolidated vs. consolidated formations, aquifers and the water table, thermal conductivity, reading cuttings, filling in the well log, and problem formations.
Site layout and setbacks, bore spacing and depth, mud rotary, air rotary and DTH hammer, sonic and dual-rotary, bentonite and polymers, lost circulation, and the annulus.
Why HDPE, reading the print line, SDR and pressure rating, pipe sizes, the U-bend, butt, socket and electrofusion step by step, and a good joint next to a bad one.
Why you test before it goes down, the hydrostatic test setup, reading the gauge, filling with water, weighting and inserting the loop, the tremie pipe, and what to do when it won't go down.
What grout has to do, bentonite, thermally enhanced and cement-based grouts, mixing in the right order, bottom-up tremie grouting, volume calculation, and top-off and surface seal.
Trenching to the house, parallel vs. series, the reverse-return header, manifolds and vaults, flushing and purging, antifreeze, the final pressure and flow test, and as-builts.
The job on one page, key numbers and formulas, terms you need to know, pre-drill and loop-and-grout checklists, the most frequent mistakes, and how to use the book before the exam.
At the end of the book: Exam review with key numbers, formulas and terms, plus pre-drill and loop-and-grout checklists.
Test yourself on geology, fusion, pressure testing and grouting, and see why each answer is right, so you can find your weak spots before exam day.
The most frequent mistakes on the job shown before and after, plus one-page cards for grout, fusion and pressure tests you can print and keep in the truck.
📄 This is a digital PDF book sent to your email: nothing is printed or shipped.
PDF by email: We email you Geothermal Loop Driller Illustrated as a PDF, together with the two free books. It's a single payment: no installments, no extra charges.
Coming from water wells or HVAC, you get the whole closed-loop job in the order it happens on site, one drawing per step.
You review geology, fusion, pressure tests and grout one page at a time, then check yourself with the practice questions.
You keep the numbers and checklists handy, printed and in the truck, for when a setback or a test pressure needs a second look.

Yes. It isn't a beginner's book and it doesn't teach you how to run a rig or a heat pump. It lays out the closed-loop side (layout, fusion, pressure testing, insertion, grout, headers, purging) one drawn page at a time, in job order. Coming from HVAC, the bore side is the part you'll use most.
From the NGWA CVCLD exam content, IGSHPA design and installation standards, CSA/IGSHPA C448, ASTM F2620 and D3035/D3350, and state well construction codes. It's written for U.S. jobs, in feet, psi and gallons. Setbacks and test rules change by state, so state numbers are shown as clearly marked examples, and every standard is flagged so you can check it against your state's current code.
No. It's an independent illustrated study book. It isn't published or endorsed by NGWA, IGSHPA or any state agency.
No. It helps you review and organize what you learn in training and on the job. It doesn't give you a certificate or continuing education credits: certification comes only from your certifying body. Your state's code and your certifying body always come first.
No. They're written for this book, in exam style, with the answers explained. They're not official exam questions.
The book and both bonus books come as PDFs by email, sent to the address you enter at checkout.
No. It's a one-time payment, not a subscription. You pay once and get the book and both bonus books as PDFs by email.
