## Exam Details

The Nevada **C-37A Solar Water 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 includes the following subject areas:

- **Piping**
- **System Design**
- **Pumps and Storage Systems**
- **Collectors**
- **System Valves and Controls**
- **Safety**

Candidates should prepare for a combination of code-based plumbing questions and practical solar thermal questions. The Uniform Plumbing Code is particularly useful for piping, materials, water-system provisions, fittings, supports, valves, and related installation requirements.

System-design questions require candidates to understand how solar collectors, piping, circulation, storage tanks, pumps, controls, and heat-transfer components work together to provide heated potable water.

Collectors, pumps, storage, valves, and controls should not be studied in isolation. Each component affects system operation, and exam questions may require candidates to understand relationships among several parts of the system.

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 maintaining that pace.

## Open Book Test

The Nevada C-37A Solar Water Heating Contractor examination is an **open-book test**.

The reference included in this package that is allowed into the trade examination 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**

Candidates should use the Uniform Plumbing Code regularly throughout preparation. Become familiar with the table of contents, index, definitions, chapter organization, tables, exceptions, and cross-references.

Open-book testing is most effective when candidates already understand how the code is organized. Searching the entire book for every question can use too much time, especially when the average pace is approximately two minutes per question.

For questions involving piping materials, fittings, supports, valves, potable water, or connections, identify the technical subject first and then use the index or table of contents to narrow the search.

Questions involving collector operation, solar thermal system design, storage, pumps, controls, or jobsite safety may rely more heavily on knowledge developed before test day.

## Licensing Steps

1. **Confirm the C-37A classification.** Make sure Solar Water 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-37A classification.
4. **Submit the Nevada contractor license application.** Complete the applicable application and supporting documents.
5. **Receive examination eligibility.** After the applicable application and qualification requirements are addressed, proceed with required testing.
6. **Prepare for the C-37A 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-37A** as the Water Heating subclassification under the broader C-37 Solar Contractor classification.

The C-37A scope covers the **installation of systems for the collection of solar energy to heat water for potable uses**.

The classification does not authorize installation of pipes or fixtures other than **water heaters and storage tanks designed for the use of the water so heated**. Candidates should understand this scope limitation when studying for the trade examination and when evaluating the type of work authorized by the classification.

C-37A work can involve solar collectors, circulation piping, pumps, storage tanks, heat exchangers, valves, controls, insulation, and related components used to collect and transfer solar energy into potable water heating systems.

Because the classification involves potable water, plumbing-code knowledge is especially important. Candidates should be comfortable working with applicable Uniform Plumbing Code provisions involving materials, water systems, piping, fittings, supports, valves, and connections.

The C-37A 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.

## Reference Books

- **Uniform Plumbing Code, 2018**
The exam-room-approved reference supports preparation involving potable water systems, piping materials, fittings, supports, valves, connections, water heaters, storage, and related plumbing code requirements relevant to solar water heating installations.
- **Code of Federal Regulations - 29 CFR Part 1926 (OSHA)**
The study-only reference supports preparation involving construction safety, fall protection, ladders, personal protective equipment, tools, electrical hazards, material handling, and other jobsite safety topics.
- **Solar Water and Pool Heating Design and Installation Manual**
The study-only reference supports preparation involving solar thermal system design, collector layouts, circulation, piping, pumps, storage tanks, valves, controls, heat transfer, and installation practices relevant to solar water heating.

## Exam Room Approved Books

- **Uniform Plumbing Code, 2018**
Uniform Plumbing Code, 2018 is the exam-room-approved reference included in the Nevada Solar Water Heating Contractor (C-37A) Exam Book Package. Candidates should practice locating potable water, piping, materials, fittings, supports, valves, connections, water-heating, and related plumbing provisions efficiently.

## Test Information and Study Materials

A strong Nevada C-37A preparation plan should begin with complete **solar water heating system design**. Candidates should understand how solar collectors, piping, pumps, storage tanks, heat exchangers, valves, and controls operate together rather than treating each component as an isolated subject.

Follow the movement of thermal energy through the system. Understand how solar energy is captured at the collector, transferred into water or another working medium, circulated through piping, stored when necessary, and ultimately used to provide heated potable water.

**Piping** should receive substantial 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 rather than only during the final days before the exam. Repeated use helps candidates become more familiar with how the code is organized.

Practice locating code requirements by topic. Begin with a question involving pipe material, identify the key term, use the index, and locate the corresponding section. Repeat the same process with fittings, supports, valves, water heaters, storage tanks, and potable water provisions.

**Definitions** can be important because plumbing terminology may have a specific code meaning. Understanding the definition 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.

**Exceptions** can modify a general requirement. Candidates should read the surrounding code language carefully before selecting an answer.

**Cross-references** may direct the candidate to another section containing additional requirements. Practice following them instead of assuming the first section contains the complete answer.

**Collectors** are a core solar water heating component. Candidates should understand collector function, arrangement, mounting concepts, orientation, circulation, and how collectors transfer solar energy into the working fluid.

Review how collector configuration affects flow and how multiple collectors can operate as part of a larger thermal system.

**Pumps** should be studied in relation to circulation. Candidates should understand why pumps are used, how they move fluid through collectors and storage systems, and how improper circulation can affect performance.

**Storage tanks** are specifically important in solar water heating because solar energy availability and hot-water demand do not always occur at the same time. Candidates should understand how storage supports system operation.

## More on test Information and Study Materials

**Heat exchangers** may be used to transfer thermal energy between separate fluid circuits. Candidates should understand their purpose and the basic relationship between the collector loop and potable water.

**System Valves and Controls** should include shutoff valves, check valves, balancing devices, temperature controls, differential controls, and other components used to regulate operation and circulation.

**Safety** preparation should include roof access, ladders, elevated work, personal protective equipment, tools, material handling, hot surfaces, electrical control components, and other construction hazards.

The **Code of Federal Regulations - 29 CFR Part 1926 (OSHA)** should be used during preparation to build retained safety knowledge because it is not allowed into the trade examination room.

The **Solar Water and Pool Heating Design and Installation Manual** can help connect multiple C-37A exam topics. Use it to review collector layouts, piping configurations, pumps, storage, controls, valves, circulation, heat-transfer concepts, and complete system operation.

Because this manual is not allowed into the exam room, active recall is useful. After reviewing a system diagram, close the book and explain the flow path and purpose of each major component from memory.

**Potable water** considerations should receive careful attention because the C-37A classification specifically covers systems used to heat water for potable uses.

Candidates should understand the relationship between the solar thermal system and the water-heating and storage components authorized by the classification.

**Heat transfer** is central to solar water heating. Understand how solar radiation becomes usable thermal energy and how that energy moves from the collector into the water-heating system.

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

**Insulation** helps reduce unwanted heat loss between the collector, storage system, and final water-heating application. Candidates should understand why solar thermal piping is insulated and how outdoor exposure affects system performance.

**Thermal expansion** should also be considered in systems exposed to elevated temperatures. Pipe movement, materials, supports, and system design can all affect installation.

A useful study schedule should divide preparation among Piping, System Design, Pumps and Storage Systems, Collectors, System Valves and Controls, and Safety.

## More on test Information and Study Materials

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

Timed UPC lookup drills can improve open-book performance. Choose 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 code requirements, while many practical solar water heating questions require retained technical knowledge.

When a practice question is missed, identify the reason. The issue may involve weak trade knowledge, unfamiliar terminology, slow reference navigation, or difficulty understanding the relationship between multiple system components.

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