Product Details
Description
Nanrun NRTHC dual-tube electric pool heater adopts industrial durable construction, power range 21~40KW, built with flow switch only, designed for medium & large residential pools, water parks and high-load commercial scenes.
Product Core Advantages
High-efficiency Dual-tube Heating Structure
Dual heating tubes expand the heat exchange area, accelerate heating speed and balance water temperature distribution. It maintains stable constant temperature operation for large pools and water parks with large circulating water flow.
Industrial-grade 304 Stainless Steel Construction
The whole unit is made of 304 stainless steel, resisting corrosion from chlorine-containing pool water. It effectively avoids rust and water leakage during long-term continuous operation to extend service life.
Integrated Safety & Digital Monitoring System
Fitted with a water flow switch that automatically stops heating when water flow disappears to prevent dry burning. A built-in digital display shows real-time water temperature, and fault indicator lights support rapid inspection and maintenance.
Key Upgrades (vs Single-Pipe Heaters)
- Larger heat exchange area realizes faster and more uniform heating effect.
- Two tubes share thermal load to reduce component loss and extend service life.
- It supports stable long-term operation under high-load and large-flow conditions.
