Hurlcon MX vs AstralPool MX Gas Pool Heaters – What's Changed and Why It Matters

For over a decade, the Hurlcon MX gas heater was a reliable and popular choice for Australian pool owners. With its compact size, efficient heating, and durable construction, it was often the go-to option for fast pool heating solutions. Today, the MX range lives on under a new name—AstralPool MX—but many pool owners still ask:

“What’s the difference between the original Hurlcon MX and the new AstralPool MX heaters?”

In this article, we compare the two models, highlight their differences in design and specification, and help you decide which version suits your pool heating needs.

A Bit of History: Hurlcon Becomes AstralPool

Hurlcon was an Australian company known for its high-performance pool and spa equipment. In the late 2000s, Hurlcon was acquired by AstralPool, part of the global Fluidra Group. While many product lines were retained, some—like the MX series—were re-engineered and rebranded under AstralPool.

The new AstralPool MX heaters maintain many of the core features that made the Hurlcon MX popular, but they also introduce important updates in size, capacity, and compliance.

What’s the Same?

Both Hurlcon and AstralPool MX heaters are:

• ✅ Gas-fired, high-efficiency pool heaters
• ✅ Designed for outdoor installation in Australian conditions
• ✅ Built with a compact footprint for tight installation spaces
• ✅ Compatible with standard 20mm or 25mm gas connections
• ✅ Designed for fast pool heat-up in residential settings

They’re both available in multiple output capacities to suit different pool sizes—from small backyard pools to large residential installations.

What’s Different?

📏 1. Size & Footprint

One of the most noticeable changes is the physical size of the units.

• Hurlcon MX units were more compact in length but taller in height.
• AstralPool MX heaters tend to be slightly longer and lower in height, giving them a squatter, more modern appearance.

Note: If you're replacing a Hurlcon MX with an AstralPool MX, double-check the dimensions—some installations may need slight repositioning.

⚙️ 2. Gas Input & Performance

The Hurlcon MX range topped out at 480 MJ/hr (MX500), while the AstralPool MX range currently peaks at 350 MJ/hr (MX400). If you're replacing a Hurlcon MX500, there may not be a one-to-one match unless you switch to a different line like the AstralPool ICI series.

💡 3. Product Line Structure

Hurlcon offered 7 models (MX125–MX500), whereas AstralPool offers 5 (MX150–MX400). This simplifies selection but may limit options for larger pools.

Replacing a Hurlcon MX Heater

Many Australian homeowners still use Hurlcon MX heaters, and most are now 10+ years old. If you’re starting to experience:

• Longer heating times
• Increased gas usage
• Age-related wear and tear
• Difficulty sourcing parts

…it may be time to upgrade. The good news? AstralPool MX heaters are compatible replacements in most cases, and HeaterFix can help you select the correct size based on your pool volume and usage.
