Frequently Asked Questions
Q1: Is this suitable for a 26L water heater?
A1: Yes, the "24L+" designation indicates compatibility with models exceeding 24L, including 26L units, thanks to its oversized heat exchange capacity.
Q2: How does this improve performance over original parts?
A2: It features enhanced fin design and larger heat transfer area, providing approximately 18% better efficiency and faster heating recovery.
Q3: What's the expected lifespan?
A3: With proper water quality and maintenance, it typically lasts 8-10 years, outperforming many standard exchangers.
Q4: Can this handle hard water conditions?
A4: The copper construction provides good corrosion resistance, but for areas with very hard water, a water softener is recommended to extend lifespan.
Q5: Is professional installation required?
A5: While designed for direct replacement, we recommend installation by qualified technicians to ensure optimal performance and warranty coverage.
