Heating Engineer (Boiler Technician) Resume Examples
A heating engineer resume gets a call when a service manager sees the systems you can actually fix (gas and oil boilers, hydronics, furnaces), your call volume and first-time fix rate, your EPA 608 and NATE credentials, and a clean driving record. Below is a full example plus apprentice and commercial versions.
Heating engineer resume example (residential and light commercial hydronics)
A fictional technician, written the way a service manager reads. The systems come before the duties, the call numbers are in the bullets, and the licenses sit in their own block because dispatch cannot send you out without them.

Skills
What a service manager checks in the first minute
The person reading is usually a service manager who needs a truck filled before the heating season starts. They are checking whether they can dispatch you unsupervised, and how soon.
- Which systems you can actually work on. Gas boilers, oil boilers, steam, hot water, condensing, forced air, heat pumps, radiant. A resume that says "HVAC systems" tells a hydronics shop nothing. List the fuel types and the distribution types.
- Whether you can be sent alone. First-time fix rate, callback rate, calls per day, and whether you have carried an on-call phone. These say more about employability than any adjective.
- Licenses and cards. EPA 608, NATE, plus whatever your state, county or city requires for gas work. Dispatch is a legal question before it is a skills question.
- Driving record and availability. A clean license, comfort with an on-call rotation and willingness to work the October to March crunch matter more in this trade than in almost any other.
“Tell me what you can commission on your own and how often you go back a second time. If a resume gives me the boiler brands and a callback percentage, I book the interview before I finish the page.”

Licenses, EPA 608, NATE and manufacturer training
This is the block a service manager reads first, so put it near the top if your license set is strong. Use the exact names.
- EPA Section 608 Technician Certification: legally required to buy or handle refrigerant. Type I, II, III or Universal. Say which. Even pure heating shops usually want it because technicians cross over to cooling in summer.
- NATE certification from North American Technician Excellence: Core plus a specialty such as Gas Heating, Oil Heating, Hydronics Gas, Air Conditioning or Heat Pump. List the specialty, not just "NATE certified".
- State, county or city licensing: requirements for gas fitting, mechanical and boiler work vary a great deal across the US, and some cities license separately from the state. Name yours with the issuing authority and expiration, and check your own state and city requirements before you claim to meet them.
- Boiler operator or stationary engineer licenses: issued by some states and cities for operating pressure vessels above a threshold. Relevant for commercial and institutional plants.
- OSHA 10 or OSHA 30 Construction, and EPA Lead-Safe Renovator (RRP) if you work in homes built before 1978.
- Manufacturer training: Weil-McLain, Burnham, Navien, Rinnai, Lochinvar, Buderus, Carrier, Trane. Naming the brands you are trained on is one of the strongest signals on this resume, because shops carry specific lines.
- In the UK, gas work legally requires registration with the Gas Safe Register. That registration does not transfer to the US, so if you trained there, list it as past experience and add the US credentials you now hold.
Add your driver's license status and whether you have a clean record. Almost every posting in this trade asks, and candidates who leave it out get asked in the screening call anyway.
The equipment list that does the real work on this resume
Service managers hire for the systems on their route. A short, specific equipment block often beats the whole skills section. Group it so a reader can scan it in five seconds.
- Heat sources: cast iron and steel gas boilers, oil-fired boilers, condensing and modulating boilers, combi boilers, warm air furnaces, indirect and tankless water heaters, unit heaters.
- Distribution: hot water baseboard, cast iron radiators, one-pipe and two-pipe steam, radiant floor with PEX manifolds, zone valves and zone panels, circulator pumps, expansion tanks, air separators.
- Controls and safeties: aquastats, low-water cutoffs, pressure relief valves, vent dampers, outdoor reset, thermostats and zoning controls, ignition modules, flame rectification.
- Test instruments: combustion analyzer, manometer, multimeter, clamp meter, inspection camera, CO monitor, smoke tester for oil, draft gauge.
- Fabrication: copper soldering and press, black iron gas pipe, PEX and PEX-AL-PEX, threading, CSST where permitted locally.
If your route is mostly steam, say so in the headline. Steam heating is a shrinking skill in most of the country, and shops that have steam buildings on the books will call a candidate who names it.
Apprentice, helper or trade school graduate
With no heating seasons behind you, the resume has to prove three things: you have the card, you can hold a meter, and you will show up at 6 a.m. in February.
- 1Get EPA 608 before you apply. It is inexpensive, it is the first filter, and having it already puts you above most other entry applicants.
- 2Count your school hours: "640 lab hours on gas heat, electrical and refrigeration" is real training, so write it as a number instead of naming the program only.
- 3List everything you have physically done, even as a helper: pulled a burner assembly, replaced an ignitor, changed a circulator, ran PEX, cleaned a chimney base, carried boilers up basement stairs.
- 4Put reliability facts on the page: clean driver's license, no restrictions, comfortable on call, able to lift 75 pounds, own hand tools.
- 5Add any adjacent work that transfers. Plumbing helper, appliance repair, auto mechanic and electrical helper all read well, because they show meter work, fault finding and customer contact.
Format, length and posting keywords
One page. Reverse chronological. No photo and no date of birth. Trade employers scan for license names and equipment, so keep those in plain text rather than in a graphic or a sidebar column.
- Mirror the posting language: boiler, hydronic, forced air, condensing, combustion analysis, gas piping, brazing, EPA 608, NATE, service call, callback rate, preventive maintenance, on-call, no-heat.
- Larger mechanical contractors and utilities use applicant tracking systems, so use one column, standard headings, and a PDF named FirstName-LastName-Heating-Technician.pdf.
- Put licenses and certifications above education. Your license is the reason you can be dispatched; your certificate is background.
- Give truck-level facts: service area, calls per day, whether you ran your own truck, and the software you invoiced in (ServiceTitan, Housecall Pro, FieldEdge).
- If your work is seasonal, group the summers rather than leaving gaps. Many heating technicians do cooling or construction in summer, which is normal and worth naming.
Frequently asked questions
What does a heating engineer do, and what should the resume emphasize?
Installs, services and repairs heating systems: gas and oil boilers, furnaces, hydronic distribution, controls and safeties. The resume should emphasize which fuel types and system types you handle, your diagnostic work (combustion analysis, meter testing, safety checks), and how many calls you complete without a return visit.
Is a heating engineer CV different from a US heating technician resume?
The content overlaps almost entirely; the conventions differ. A US resume is one page, has no photo, no date of birth and no marital status, and uses US license names such as EPA 608 and NATE rather than Gas Safe registration. Keep the UK term out of your US headline except as a one-line note about where you trained.
Do I need EPA 608 if I only work on boilers?
Not for the boiler work itself, since EPA Section 608 covers refrigerant handling. In practice most employers still want it, because heating technicians move onto air conditioning work in summer and the certification never expires. It is cheap to get and removes an objection.
What skills should I put on a heating technician resume?
Combustion analysis and CO testing, gas and oil burner setup, boiler and furnace diagnosis, hydronic piping and balancing, gas pipe sizing and pressure testing, control and safety wiring, brazing and soldering, plus the dispatch software you use. Then name the boiler brands you are factory trained on.
How do I write a heating resume with no experience?
Lead with your EPA 608 card, your trade school lab hours as a number, and the specific tasks you have done as a helper. Add reliability facts most employers ask about anyway: clean driver's license, ability to work on call, comfort with basement and crawlspace work, own hand tools.
Should I list first-time fix rate and callback rate?
Yes, if your shop tracked them and you can quote the target you were measured against. An 88% first-time fix rate against a company target, or a 4% callback rate, is the fastest way to show you can be sent out alone. If nobody tracked it, use calls per day and on-call weeks instead.
How long should a heating engineer resume be?
One page for almost everyone in this trade. Two pages only if you also carry commercial plant responsibility, project management or a supervisory license set. Keep older helper and install roles to two or three lines each.
Should I combine plumbing and heating on one resume?
Combine them if you are applying to a plumbing and heating shop, which is common in the Northeast, and lead with whichever the posting names first. If the employer is a pure heating or HVAC service company, keep plumbing to one line under skills so it does not dilute the heating story.
