📌 Key Specs

Based on official Raypak data:

• Model Series: E3T (0018 / 0027 / etc.)
• Type: Electric resistance pool heater
• Heating element: Titanium (corrosion-resistant, saltwater compatible)
• Power supply: 240V single-phase (most models)
• Efficiency: ~100% (all electricity converted to heat)
• Water flow range: up to ~60 GPM
• Control system: Digital LCD with diagnostics
• Installation: Indoor or outdoor rated

🔥 Available Sizes (heat output)

Common E3T models:

• ~37,000 BTU class (small spa / hot tub)
• ~61,000 BTU class (medium spa / plunge pool)
• ~80,000–100,000 BTU class (larger spa systems)

(BTU is “heat output equivalent” — electric heaters are rated differently but behave like continuous-output heaters.)

⚙️ Key Features

✔ Fully digital control panel (temp + diagnostics)
✔ Titanium heating element (very corrosion resistant)
✔ Works with saltwater pools
✔ Built-in flow sensor (prevents dry firing)
✔ Freeze protection
✔ Compact wall-mount design
✔ Quiet operation (no combustion)

🧠 How it works (simple)

• Water flows through a heating chamber
• Electric current heats titanium elements
• Heat transfers directly into water
• No gas, no flame, no venting required

👍 Advantages

• 🔌 Easy installation (no gas line needed)
• 🧂 Safe for saltwater pools
• 🧱 Compact equipment pad footprint
• 📊 Accurate digital temperature control
• 🔧 Lower maintenance than gas heaters
• 🌿 Clean operation (no emissions)

⚠️ Limitations (important)

• ⚡ High electricity usage (expensive to run for large pools)
• 🐢 Slower heating compared to gas heaters
• 🏊 Best for spas / small pools (not large 20k+ gallon pools)
• 🔌 Requires heavy electrical wiring (often 30–60A circuits)
