Whether my customer lives in a condo or single-family home, I am certain these tankless water heaters can effortlessly keep up with their hot water needs.

Flexible Options

Tailor your system to your preferences and needs by selecting the fuel source that suits you best. The Eccotemp Builder Series is available in both liquid propane and natural gas, ensuring you have the flexibility to meet your individual requirements.


Natural gas is a cost-effective choice for water heating, often more budget-friendly than electricity. It provides a swift and reliable hot water supply, making it particularly well-suited for larger households. However, it's important to note that access to a natural gas supply line is essential, and availability may vary by region. If a gas line extension is required, there may be slightly higher installation costs.


Conversely, propane provides versatility and serves as a dependable alternative in areas without access to natural gas. It efficiently fuels your water heater, ensuring a consistent hot water supply. It's important to note that propane tanks need periodic refilling, which can lead to additional costs. Nevertheless, many homeowners appreciate the independence and self-sufficiency that come with having their dedicated fuel source.

Safety and Certification

Eccotemp’s Builder Series Tankless Water Heaters proudly hold CSA certification, a testament to their quality and safety. These units have undergone rigorous CSA testing and received approval for installation in the United States and Canada, up to elevations of 2,000 feet. However, it's important to note that installing the Builder Series at higher elevations may impact performance and isn't recommended. This certification underscores Eccotemp’s commitment to providing dependable and secure water heating solutions while aligning with the Department of Energy's mission to advance energy-efficient technologies and uphold the highest quality and safety standards.


Installation Requirements

Our tankless water heaters are designed for a trouble-free installation, offering user-friendly features like easy wall mounting and compatibility with a 110/120-volt UL-listed power cord. They include ¾-inch NPT water and gas connections, further streamlining the installation process. To ensure a proper installation, we recommend the use of steel gas lines. If you opt for a flex steel gas line, it's crucial that it's appropriately rated to prevent any operational issues. Specifically, for the Builder Series tankless water heater, a flex steel gas line with a minimum rating of 145,000 BTU for the 6.0 GPM variant, 170,000 BTU for the 6.5 GPM variant, and 180,000 BTU for the 7.0 GPM variant are required for proper operation, and a higher rating is preferred when possible. Additionally, we advise minimizing any 90-degree turns in your steel gas line, as each turn can reduce the maximum BTU output below the 180,000 BTU required for your Builder Series, potentially leading to gas error codes.


Ensuring a smooth installation process is essential for achieving the optimal performance and safety of your water heater. To prevent common installation mistakes like incorrect sizing, improper vent material, and overlooking the right gas line size, water connections, or electrical connections, it's crucial to adhere to the Manufacturer's Guidelines. If necessary, don't hesitate to seek professional assistance to sidestep these common pitfalls during installation. We also highly recommend the installation of a Service Valve Kit for periodic descaling and damage-preventative maintenance, which seamlessly connects to our EZ-Flush System Descaling Kit.


Venting

Selecting the right Indoor Tankless Water Heater entails careful consideration of venting, a crucial factor for both safety and efficiency. The 7.0GB Builder Series is exclusively designed for outdoor installation, eliminating the need for a venting system. In contrast, the 6.0GB and 6.5GB Builder Series are tailored for indoor use, requiring a 3-inch venting setup. Simplify installation with Eccotemp’s Stainless Steel 3" Horizontal Vent Kit or 3” Vertical Vent Kit (additional vent pieces may be needed). The horizontal kit enables exhaust gas venting through a sidewall, making it ideal for spaces with limited vertical venting options. Conversely, the vertical kit allows for venting through the roof, a suitable choice for multi-story buildings or situations where vertical venting is preferred. Selecting the appropriate vent kit guarantees the safe expulsion of combustion gases, contributing to the optimal performance and safety of your indoor tankless water heater.


Common errors in venting tankless water heaters, whether installed horizontally or vertically, can result in decreased efficiency and potential product harm. Condensation forms when hot exhaust gases cool upon exiting the vent, leading to moisture buildup.


In horizontal installations, an improper vent slope is a frequent misstep that can cause condensation to accumulate and flow back into your tankless water heater, potentially causing significant damage not covered by your manufacturer's warranty. That's why we always stress the importance of ensuring the correct slope away from your tankless water heater and recommend the installation of a Horizontal Condensation Drain Pipe (available separately) to mitigate this risk.


Improper horizontal installation: No drain pipe, wrong venting materials (must be stainless steel), no backflow preventer


In vertical installations, the correct venting setup is equally vital to safeguard your tankless water heater from potential harm. We strongly recommend the inclusion of a Vertical Condensation Drain Pipe in any tankless water heater installation, especially in areas where temperatures can fluctuate. Additionally, it's crucial to ensure the installation includes a backflow preventer, which acts as a barrier to prevent cold air from flowing back into your water heater, particularly during freezing temperatures and windy conditions. Lastly, it's advisable to have a properly sized drain pan positioned beneath your tankless water heater, ready to catch any water leakage in case of a break, freeze, or damage to ensure that your home remains protected.


Improper vertical installation: No drain pipe, no backflow preventer, no downward slope to avoid condensation returning to the water heater.


Tips and Tricks

Following the manufacturer's maintenance guidelines is crucial for extending the lifespan of your tankless water heater. Regular flushing is a key component in preventing mineral buildup and should be carried out at least once a year, although the frequency may vary depending on your water source. For those using well water, we highly recommend descaling your tankless water heater at least twice annually. Our purpose-built EZ-Flush System Descaler Kit is an invaluable resource specifically designed to address even the most stubborn buildup. By maintaining these consistent practices, you not only extend the life of your tankless water heater but also ensure its ongoing operational efficiency.
