Exam Details

The Nevada C-37D Solar Pool 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 category with 15 questions. Candidates should spend significant preparation time understanding how solar collectors, piping, circulation, heat exchangers, pumps, valves, and controls work together as a complete solar pool heating system.

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

Collectors accounts for 7 questions. Candidates should understand collector function, layout, circulation, mounting considerations, and how collectors connect with the rest of the solar pool 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-37D Solar Pool 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 works best when candidates already understand where information is likely to be located. Searching the entire code for every question can consume too much time, especially when the average pace is about two minutes per question.

For questions involving pipe materials, supports, fittings, 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 system design, collectors, pumps, 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 as a substitute for broader solar pool heating preparation.

Licensing Steps

1. Confirm the C-37D classification. Make sure Solar Pool 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-37D 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-37D 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-37D as the Heating of Pools subclassification of the broader C-37 Solar Contractor classification.

The C-37D scope covers the installation of collectors, piping, and heat exchangers used to heat swimming pools and spas with solar energy.

The classification does not authorize plumbing swimming pools or installing their equipment. Candidates should therefore understand that the classification is focused on solar heating components rather than general pool plumbing.

Typical C-37D work can involve solar collectors, circulation piping, heat exchangers, valves, controls, and related components that transfer collected solar energy into swimming pool or spa water.

Understanding how those components operate together is important because the examination tests system concepts, not just isolated parts. The outline combines System Design, Piping, Collectors, Pumps and Storage Systems, System Valves and Controls, and Safety.

The C-37D 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.

  This exam-room-approved reference supports preparation involving piping systems, pipe materials, fittings, supports, valves, connections, and related plumbing requirements applicable to solar pool heating installations.

Exam Room Approved Books

• Uniform Plumbing Code, 2018
  This is the exam-room-approved reference included in the Nevada Solar Pool Heating Contractor (C-37D) Books Allowed into Exam Package. Candidates should practice locating piping, material, fitting, support, valve, connection, and related plumbing provisions efficiently.

Test Information and Study Materials

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

Candidates should understand how solar collectors, piping, pumps, heat exchangers, valves, and controls work together as a complete solar pool heating system rather than memorizing each component separately.

Follow the path of heat through the system. Understand how solar energy is absorbed by the collectors, transferred into the circulating medium, moved through piping, and ultimately delivered to the swimming pool or spa.

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 make the organization of the code more familiar.

Practice locating code requirements by topic. Start with a question involving pipe material, identify the key term, use the index, and locate the appropriate section. Repeat the process with fittings, supports, valves, and connections.

Definitions can be important because technical plumbing terms may have specific code meanings. Understanding those definitions can help determine which requirement applies.

Tables should receive regular attention. Important information involving materials, supports, sizing, or installation conditions may appear in table form rather than narrative text.

Exceptions can modify a general requirement. Candidates should read the surrounding code 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 instead of assuming the first section contains the complete answer.

Collectors accounts for 7 questions. Candidates should understand collector purpose, layout, mounting concepts, orientation, circulation, flow relationships, and how collector arrays connect with the rest of the solar pool heating system.

Review how collector arrangement can affect system flow and how solar energy is transferred from the collector surface into the working fluid.

Pumps and Storage Systems accounts for 5 questions. In solar pool heating applications, candidates should understand pump relationships, circulation, and how heated water moves through the system.

Review how proper circulation affects the ability of collectors and heat exchangers to transfer thermal energy efficiently.

System Valves and Controls accounts for 3 questions. Candidates should review shutoff valves, check valves, balancing devices, bypass arrangements, 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 study plan also covers solar pool heating system design, collector layout, pumps, heat exchangers, valves, controls, and safety through technical study resources and trade experience.

Heat transfer is central to solar pool heating. Candidates should understand how solar radiation is converted into thermal energy at the collector and how that energy is transferred into pool or spa water.

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

Heat exchangers are specifically part of the C-37D scope. Candidates should understand their purpose and how they can transfer thermal energy between different fluid circuits when used in a system.

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

Insulation is important because unwanted heat loss can reduce system performance. Candidates should understand why solar thermal piping is insulated and how outdoor exposure can affect insulation considerations.

Thermal expansion should also be considered in piping systems exposed to elevated temperatures. Materials, supports, and layout all influence 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, pump issue, control question, or safety topic.

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

Do not expect the Uniform Plumbing Code to answer every question. The code is most useful for targeted plumbing requirements, while many practical questions depend on retained solar pool heating knowledge.

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

Correcting the underlying weakness is more valuable than memorizing a single 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.
