Raypak 100-10000665 Electric E3T Heater | 18KW

Raypak E3T 18kW Electric Pool & Spa Heater | 100-10000665

The Raypak E3T 18kW electric heater is built to deliver precise, dependable, and efficient heating performance for both pools and spas. Featuring advanced solid-state technology and digital control precision, it ensures stable water temperature and long-term reliability in both residential and light commercial settings. Designed for quiet operation and longevity, the E3T features titanium heating elements that withstand the corrosive effects of chlorinated and saltwater environments, significantly reducing maintenance needs and extending service life.

Compact yet powerful, the E3T’s NEMA 3R-rated enclosure enables flexible installation indoors or outdoors—even in tight equipment spaces. Integrated safety and protection systems include water-flow monitoring, freeze prevention logic, and temperature-based safeguards to prevent dry-firing, element burnout, or thermal shock. A high-visibility digital display provides live data for inlet and outlet temperature, flow rate, and system diagnostics—streamlining setup and troubleshooting for technicians.

Fully compliant with California Title 24 energy standards, the E3T offers an eco-conscious heating solution that meets the updated 2026 efficiency requirements. It’s designed to help homeowners and facility managers maintain consistent water comfort while reducing operating costs and staying ahead of upcoming regulatory changes—all without compromising Raypak’s renowned reliability.

Smart Digital Heating Control

Raypak’s advanced electronic control system gives users unmatched precision and insight into heater performance. The clear, full-text display eliminates the confusion associated with older units that rely on blinking indicators—each message is spelled out on the screen for easy interpretation. On the 18kW and 27kW models, a 12-character LCD provides detailed, expanded feedback for temperature status, alerts, and operation logs.

For automation integration, the E3T includes dedicated two-wire connectors, enabling compatibility with third-party control systems for remote management and scheduled heating cycles within larger pool automation networks.

Protection & Performance Engineering

Engineered for longevity, the E3T incorporates multiple automatic safeguards to prevent premature wear and protect internal components under varying water conditions.

Core protection systems include:

• Flow Protection: Automatically shuts off power if flow falls outside the safe 15–60 GPM range, eliminating dry-fire risk.

• Low-Temperature Mode: Prevents element shock during sudden cold-water influxes.

• Freeze Protection: Deactivates the system when inlet temperature drops to 32°F (0°C) to prevent freeze damage.

• Element Failure Detection: Continuously monitors the element’s condition, identifying degradation early to prevent breakdowns.

• One-Minute Restart Delay: Reduces cycling frequency, preventing burnout and extending component life.

Together, these systems ensure safe, steady, and reliable operation across a variety of environmental conditions.

Durability for Demanding Environments

Every E3T heater features titanium heating elements—providing superior corrosion and scale resistance even in saltwater or chemically balanced pools. The heavy-duty housing is designed for year-round exposure, with a NEMA 3R outdoor rating that supports installation in both mechanical rooms and open equipment pads.

Built for versatility, the E3T is ideal for spas, resistance pools, hydrotherapy setups, and small in-ground pools where consistent heating performance and uptime are critical. Its combination of strength, precision, and protection makes it one of the most reliable electric heaters available today.
