What is Thermal Engineering?: Course Fees 2025, Subjects, Top Colleges, Admissions

Thermal Engineering is a popular specialisation within Mechanical Engineering that revolves around the concepts of how thermal energy or heat is generated, transferred, and utilized for various purposes like the generation of power, optimal heating and cooling, and overall energy management, both at homes and in industrial settings, reducing the loss of energy and impact on the environment.

The duration of Thermal Engineering courses varies on the basis of the course level at which you're planning to pursue the course. At the UG level, most of the colleges offer integrated BTech-MTech courses that have a general time span of 5 years in India. Coming to the PG level, a plethora of colleges offer the M Tech in Thermal Engineering course with a duration of 2 years, which gives you advanced-level knowledge of the field and acts as an entry point for a rewarding career journey.

For UG courses in Thermal Engineering, you should get at least 50 to 60% marks in Physics, Chemistry, and Mathematics subjects, which may differ from one college to another. For example, for an Integrated BTech Mechanical engineering + M Tech Thermal Engineering at the IITs, you should have at least 75% marks in your Class 12 board exams.
Further, for PG courses like M Tech in Thermal Engineering, you must have at least 55 to 60% marks in graduation. Other than meeting the eligibility criteria, you also need to clear relevant entrance tests with excellent marks.

To get admission to Thermal Engineering courses at some of the best colleges in India, you should start by checking the eligibility requirements and make sure to meet them. Appearing for the entrance tests and scoring outstanding marks and rank in the exam is also quite important.

Another crucial step is to fill out the college application forms without fail before the registration window gets closed. After the exam results are out and you've got your marks and rank, you need to apply for the counseling process via the online portal.

You must go for the counseling process, where you'll be given a seat according to your marks and rank in the exam. After getting the seat, you need to go to the college and pay the Thermal Engineering course fee and get your seat confirmed.

A few colleges may offer admission on the basis of Class 12 merit, for which you must check the respective college websites to have better clarity.

The admission process for M.Tech Thermal Engineering can easily take up 3 to 5 months from the entrance exam to the final seat allotment. This is because every college has to complete a lot of formalities before giving admission to the students. The basic steps include entrance examination, college application, result announcement, cutoff release, college counseling, seat allotment, course fee payment, document verification, and final admission confirmation.

When it comes to pursuing Thermal Engineering in India, you can take several entrance tests for securing admission to some of the best colleges in the country offering courses in this field at the UG and PG level.

You can check the number of colleges that accept certain exam scores and then decide the exam they would like to appear for afterwards:

Note: Some colleges accept multiple entrance exam scores.

GATE exam is conducted only once a year to offer admissions to master's and PhD programs at top institutions, such as IITs and NITs. Qualifying GATE exam also paves the way for technical jobs in in PSUs. This year, IIT Roorkee conducted the GATE 2025 exam on Feb 1, 2, 15, and 16, 2025 in two sessions - morning and afternoon. 

GATE qualifying cutoff is the institute eligibility cutoff, and on the other hand, the GATE admission cutoff ensures a call for admission at IITs, NITs, IITs, and CFTIs. Check below in detail:

GATE Qualifying Cutoff: It is the minimum mark a candidate must score so that he or she is eligible for admission. But this does not mean that a candidate is selected for admission. Actually, it is fixed before the announcement of GATE results. It is announced by the conducting IIT and available on GOAPS. It includes qualifying marks for each paper.

Admission GATE Cutoffs: It is the final opening and closing rank score fixed by the participating institutes for the selection of candidates. It is to be noted here that meeting the admission GATE cutoff does not mean that the candidates will be selected for admission. It is fixed after the GATE result date. It is declared by the individual participating institutes and available on their respective counselling portals (CCMT/ COAP).

Total 120 questions will be asked in the AP PGECET question paper. All the questions are Multiple Choice Questions. Solving question papers helps candidates successfully clear the AP PGECET 2025 exam. Each question carries one mark, and there is no provision for negative marking. The questions will be asked in the English language.

If you are someone who wishes to get in-depth knowledge of the foundational concepts of mechanical systems and thermal energy transfer and utilization and wants to earn a dual degree in 5 years, which includes theory classes and skill-based learning via lab work, this could be a go-to course option for you. This also turns out to be a cost-effective option that can lead to promising earning opportunities in the long run.
