⚙️ 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)

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

👍 Advantages

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

⚠️ Limitations (important)

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