Zodiac JXi 370MJ Gas Heater - Maximum Heating Power When You Need It
The Zodiac JXi 370MJ Natural Gas Heater is designed for pool owners who need strong, immediate heating performance, especially for larger pools or frequent spa use.
Unlike heat pumps that heat gradually, the JXi delivers instant heat, making it ideal for:
- Quickly heating large pools before use
- Rapid spa heating
- On-demand heating without running the system continuously
With 370MJ of output, this model provides significantly more heating capacity than the 200MJ version, making it better suited to larger pools or higher heating demands.
✅ Compact Design with Easy Installation
Despite its higher output, the JXi 370MJ maintains the same compact footprint as the smaller model.
It fits on a standard 61 × 61 cm equipment pad and remains relatively lightweight at around 53 kg, making it easier to install compared to traditional gas heaters.
The 180° rotatable top allows flexible plumbing configurations, helping reduce installation complexity and additional costs.
✅ Efficient and Cleaner Operation
The JXi series combines strong performance with efficient operation.
With an 83% thermal efficiency rating, the heater converts a large portion of gas into usable heat, reducing energy waste. The low-NOx design also helps minimise emissions, meeting modern environmental standards.
This makes the JXi 370MJ a practical choice for those wanting powerful heating with responsible energy use.
✅ Simple Controls and Smart Integration
The digital control interface makes the heater easy to operate and monitor.
You can:
- Adjust pool and spa temperature quickly
- Access system diagnostics
- Track runtime and heating cycles
The unit is also compatible with AquaLink and iAquaLink systems, allowing seamless integration into automated pool setups for convenient remote control.
Who This Heater Is Best For
The Zodiac JXi 370MJ Natural Gas Heater is ideal for pool owners who need maximum heating power with fast response times.
It is particularly well-suited for:
- Large residential pools
- Pools and spas requiring rapid heat-up
- Homes that use the pool on demand rather than continuously heated
- Installations where space is limited but high output is needed
- Users wanting simple controls with automation compatibility
For those who want strong, reliable heating with immediate results, the JXi 370MJ offers a powerful and compact solution for modern pool setups.
