Exam Details

The Nevada C-37B Solar Space Heating Contractor examination contains 45 questions. Candidates are allowed 1.5 hours to complete the examination and must answer 32 questions correctly to pass.

The examination is divided into the following subject areas:

• Piping: 10 questions
• System Design: 15 questions
• Pumps and Storage Systems: 5 questions
• Collectors: 7 questions
• System Valves and Controls: 3 questions
• Safety: 5 questions

System Design is the largest section of the examination with 15 questions. Candidates should spend substantial preparation time understanding how collectors, piping, pumps, storage, heat exchangers, valves, controls, and distribution components function together in a complete solar space heating system.

Piping represents 10 questions and is one of the most important areas for Uniform Plumbing Code preparation. Candidates should understand pipe materials, fittings, joining methods, supports, routing, insulation, valves, and connections.

Collectors accounts for 7 questions. Candidates should understand how solar collectors absorb thermal energy, how fluid or air moves through the collection system, and how collector arrangement and circulation affect performance.

Pumps and Storage Systems and Safety each account for 5 questions. System Valves and Controls accounts for 3 questions. These categories may be smaller individually, but together they represent a significant portion of the test.

With 45 questions in 1.5 hours, candidates have approximately two minutes per question on average. Efficient reference use and strong retained trade knowledge are both important for managing the examination pace.

Open Book Test

The Nevada C-37B Solar Space Heating Contractor examination is an open-book test.

The reference allowed into the trade examination and included in this package is:

• Uniform Plumbing Code, 2018

The following references are included for study but are not allowed into the trade examination room:

• Code of Federal Regulations - 29 CFR Part 1926 (OSHA)
• Solar Water and Pool Heating Design and Installation Manual

The Uniform Plumbing Code should be used regularly throughout preparation. Candidates should become familiar with the table of contents, index, definitions, chapter structure, tables, exceptions, and cross-references.

Open-book testing works best when candidates already know where to look. Searching through the entire code for every question can consume too much time, especially when the average pace is approximately two minutes per question.

For questions involving pipe materials, fittings, supports, valves, or plumbing connections, identify the technical subject first and then navigate directly to the most likely UPC section.

Questions involving solar system design, collectors, pumps, storage, heat exchangers, controls, and safety may depend more heavily on retained knowledge developed during preparation.

The OSHA reference and Solar Water and Pool Heating Design and Installation Manual should therefore be used to build technical understanding before the exam rather than as test-room lookup tools.

4. Submit the Nevada contractor license application. Complete the applicable application and supporting documents.
5. Receive examination eligibility. After the application and experience requirements are addressed, the qualifying individual can proceed with the required testing process.
6. Prepare for the C-37B trade examination. Study piping, system design, pumps and storage systems, collectors, system valves and controls, and safety.
7. Practice Uniform Plumbing Code navigation. Use the 2018 UPC regularly so open-book lookups become faster and more familiar.
8. Prepare for Nevada contractor business requirements. Complete the applicable contractor business and law preparation required for licensing.
9. Complete the required examinations. Take the applicable trade and business examinations.
10. Complete remaining licensing requirements. Finish the other applicable requirements associated with contractor license issuance.

State Requirements

Nevada identifies C-37B as the Solar Space Heating subclassification under the broader C-37 Solar Contractor classification.

The C-37B scope covers the installation of systems for the collection of solar energy to heat water or air which is then used to heat structures housing persons, animals, or inanimate objects.

The scope includes storage, piping, and heat exchangers. It excludes equipment used for pools, which is addressed under the solar pool heating subclassification.

C-37B work can involve solar thermal collectors, circulation piping, pumps, storage tanks, heat exchangers, valves, controls, insulation, and related equipment used to move collected thermal energy into a structure-heating application.

Candidates should understand how the individual components of a solar heating system interact. The examination outline reflects this system-based approach by testing System Design, Piping, Collectors, Pumps and Storage Systems, System Valves and Controls, and Safety.

The C-37B trade examination is one part of Nevada contractor licensing. Applicants must also satisfy applicable qualification, application, business, financial, and other licensing requirements before a contractor license is issued.

Test Information and Study Materials

A strong Nevada C-37B preparation plan should begin with System Design because it represents 15 of the 45 examination questions.

Candidates should understand how solar collectors, piping, pumps, storage tanks, heat exchangers, valves, controls, and heating distribution components function together rather than memorizing each item separately.

Follow the path of thermal energy through the system. Understand how solar energy is captured by collectors, transferred into water or air, moved through the system, stored when necessary, and ultimately used to heat a structure.

Piping represents 10 questions and should receive significant attention. Review pipe materials, fittings, joining methods, supports, routing, insulation, thermal expansion, valves, and connections.

The Uniform Plumbing Code, 2018 should be used throughout preparation. Regular navigation practice can help candidates locate code requirements more efficiently under examination conditions.

Practice using the UPC by topic. Start with a question involving pipe materials, identify the important term, use the index, and locate the applicable provision. Repeat the process with fittings, supports, valves, and connections.

Definitions can be important because code terminology may have a specific meaning. Understanding the definition can help candidates identify which requirement applies to a particular installation.

Tables should receive regular attention. Important requirements involving materials, support spacing, sizing, or installation conditions may appear in tables.

Exceptions can change how a general rule applies. Candidates should read surrounding code language carefully instead of stopping at the first sentence that appears relevant.

Cross-references may direct the reader to another section containing additional requirements. Practice following these references so the complete requirement is understood.

Collectors represents 7 questions. Candidates should understand how solar collectors absorb energy and how collector orientation, arrangement, mounting, circulation, and connections affect system operation.

Review the differences between collecting heat into a water-based system and collecting heat into an air-based system. The C-37B scope includes solar energy used to heat either water or air before that energy is used to heat a structure.

Pumps and Storage Systems accounts for 5 questions. Candidates should understand circulation pumps, storage tanks, thermal storage concepts, heat exchangers, and the relationship between available solar energy and heating demand.

Review how storage can allow heat collected during one period to be used later and how pumps maintain circulation through collectors, piping, and heat exchangers.

System Valves and Controls represents 3 questions. Candidates should review shutoff valves, check valves, balancing devices, differential controls, temperature controls, pressure-related components, and other devices that regulate system operation.

Safety accounts for 5 questions. Use OSHA 29 CFR Part 1926 to prepare for hazards involving roof access, ladders, elevated work, personal protective equipment, tools, electrical components, lifting, and other construction activities.

Because the OSHA reference is not allowed into the trade examination room, candidates should build retained safety knowledge during preparation.

The Solar Water and Pool Heating Design and Installation Manual can help candidates connect multiple exam topics. Use it to study collectors, system layouts, circulation, piping, pumps, storage, heat exchangers, valves, and controls.

Because the manual is not allowed into the examination room, active recall is useful. After reviewing a system diagram or technical topic, close the book and describe the flow path and purpose of each major component from memory.

Heat transfer is central to solar space heating. Candidates should understand how solar radiation becomes usable thermal energy and how that heat is transferred into water or air for building heating.

Heat exchangers should receive focused study because they are specifically included in the C-37B scope. Candidates should understand their purpose and how thermal energy can move between separate fluid circuits.

Storage is another important concept. Solar energy availability and space-heating demand do not always occur at the same time, so storage can be an important part of system design.

System flow should also receive attention. Proper circulation affects collector performance and heat delivery, making balanced flow an important practical consideration.

Freeze protection can be relevant because solar thermal components and piping may be exposed to outdoor temperatures. Candidates should understand general methods used to protect exposed equipment from freezing conditions.

Insulation helps reduce heat loss between the collector, storage system, heat exchanger, and heating load. Candidates should understand why insulation is important and how outdoor exposure can affect system performance.

Thermal expansion should also be considered in systems exposed to elevated temperatures. Pipe movement, material characteristics, and support methods can all affect installation.

A useful study schedule should follow the exam outline. Spend the largest blocks of time on System Design and Piping, followed by Collectors, Pumps and Storage Systems, Safety, and System Valves and Controls.

Once individual topics become familiar, move into mixed-question practice. The examination can shift quickly from a piping requirement to a system-design question, collector concept, storage issue, control question, or safety topic.

Timed UPC lookup drills can improve open-book performance. Select a plumbing topic and practice locating the applicable requirement within a limited amount of time.

Do not expect the Uniform Plumbing Code to answer every question. The UPC is most useful for targeted plumbing requirements, while many practical solar space heating questions require retained technical knowledge.

When a practice question is missed, identify the cause. The issue may involve weak system knowledge, unfamiliar terminology, slow code navigation, or difficulty understanding how components interact.

Correcting the underlying weakness is more useful than memorizing one answer. This approach builds stronger preparation for unfamiliar questions on test day.

Time management should also be part of preparation. Answer familiar questions efficiently, use the UPC for targeted lookups, mark difficult questions, and return to them after completing items that can be answered more quickly.
