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 content 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 examination category with 15 questions. Candidates should spend substantial preparation time understanding how collectors, piping, pumps, storage, heat exchangers, valves, controls, and heating distribution components function together as a complete solar thermal system.

Piping represents 10 questions and is one of the most important areas for Uniform Plumbing Code use. Candidates should be comfortable locating requirements involving pipe materials, fittings, joining methods, supports, routing, valves, and connections.

Collectors accounts for 7 questions. Candidates should understand collector function, arrangement, circulation, mounting concepts, and how collectors connect to the rest of a solar space heating system.

Pumps and Storage Systems and Safety each account for 5 questions, while System Valves and Controls accounts for 3 questions.

With 45 questions in 1.5 hours, candidates have approximately two minutes per question on average. Efficient code navigation and strong retained trade knowledge are both important for managing that 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 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 is most effective when candidates already know how to locate information. Searching the entire code for every question can use too much time, especially when the average pace is about two minutes per question.

For questions involving pipe materials, fittings, supports, valves, connections, or other plumbing requirements, identify the technical subject first and then use the index or table of contents to narrow the search.

Questions involving solar system design, collectors, pumps, storage, heat exchangers, controls, or safety may rely more heavily on retained trade knowledge. Candidates should therefore use the Uniform Plumbing Code as a targeted code reference rather than a substitute for broader technical preparation.

Licensing Steps

1. Confirm the C-37B classification. Make sure Solar Space Heating matches the type of contracting work the business intends to perform.
2. Identify the qualifying individual. The contractor application must identify the person responsible for satisfying the applicable qualification requirements.
3. Prepare qualifying experience information. Organize the work-history documentation applicable to the C-37B classification.
4. Submit the Nevada contractor license application. Complete the applicable application and supporting documentation.
5. Receive examination eligibility. After applicable qualification and application requirements are addressed, proceed with required testing.
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 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. Equipment used for pools is excluded from the C-37B Solar Space Heating classification.

Typical C-37B work can involve solar collectors, circulation piping, pumps, storage tanks, heat exchangers, valves, controls, insulation, and related thermal equipment used for space heating applications.

Understanding how those components operate together is important because the examination tests complete system concepts rather than only isolated components. The exam outline combines 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 work together as a complete solar space heating system rather than memorizing each component separately.

Follow the path of thermal energy through the system. Understand how solar energy is captured by the 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 is one of the strongest areas for direct Uniform Plumbing Code preparation. Candidates should review pipe materials, fittings, joining methods, supports, routing, insulation, valves, and connections.

The Uniform Plumbing Code, 2018 should be used throughout preparation rather than only during the final days before the examination. Repeated use helps candidates become more familiar with the structure of the code.

Practice locating code requirements by topic. Start with a question involving pipe material, 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 plumbing terminology may have specific code meanings. Understanding those definitions can help determine which requirement applies to an installation.

Tables should receive regular attention. Important requirements involving materials, supports, sizing, or installation conditions may appear in table format rather than paragraph text.

Exceptions can modify a general requirement. Candidates should read surrounding language carefully so they do not overlook conditions that change how a rule applies.

Cross-references may direct the reader to another section containing additional requirements. Practice following those references rather than assuming the first section contains the complete answer.

Collectors accounts for 7 questions. Candidates should understand collector purpose, layout, orientation, mounting concepts, circulation, and how collectors integrate with the rest of a solar heating system.

Review how collector arrangement can affect flow and how thermal energy moves from the collector into the working medium.

The C-37B scope involves systems that may heat water or air. Candidates should understand that solar space heating can use different thermal-transfer approaches depending on the system design.

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

Review how pumps move fluid through collectors and piping and how storage can allow collected solar heat to be used later when needed.

Heat exchangers deserve focused study because they are specifically included in the C-37B scope. Candidates should understand their purpose and how they transfer thermal energy between separate parts of a heating system.

System Valves and Controls accounts for 3 questions. Candidates should review shutoff valves, check valves, balancing devices, temperature controls, differential controls, and other components that regulate operation.

Safety accounts for 5 questions. Candidates should prepare for practical hazards involving roof access, ladders, elevated work, piping tools, hot surfaces, electrical control components, lifting, and other construction activities.

Because this package contains only the exam-room-approved Uniform Plumbing Code, candidates should make sure their broader preparation also covers solar system design, collectors, pumps, storage, heat exchangers, controls, and safety through technical study materials and trade experience.

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 heating a structure.

Storage is an important design consideration because solar energy availability and space-heating demand do not always occur at the same time. Candidates should understand the general role of thermal storage in a complete system.

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

Freeze protection can be relevant because collectors and piping may be exposed to outdoor temperatures. Candidates should understand general system-design approaches used to protect exposed components from damaging conditions.

Insulation helps reduce unwanted heat loss between the collector, storage system, heat exchanger, and heating load. Candidates should understand why solar thermal piping is insulated and how outdoor exposure can affect performance.

Thermal expansion should also be considered in systems exposed to elevated temperatures. Materials, supports, and system layout all affect how pipe movement is accommodated.

A useful study schedule should follow the examination 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 actual 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 multiple 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.
