How many bathrooms can a 26L unit support?
For most homes, a 26L continuous flow unit is suitable for medium to large households and can handle multiple hot water outlets. Real-world performance depends on incoming water temperature, pipework, shower heads, and how many outlets run at once.
Is this LPG model suitable for off-grid use?
Yes. LPG is a common choice for off-grid and rural properties. You’ll still need the correct gas supply setup and compliant installation for your site.
Can I run this from bottled LPG (45kg bottles)?
Often, yes — but the bottle setup, regulator, line sizing, and expected demand all matter. If you’re unsure, tell us your location and typical usage and we can help you confirm suitability before purchase.
What’s the difference between LPG and Natural Gas (NG)?
This listing is for the LPG model. Natural Gas units are configured differently and aren’t interchangeable without the correct model and compliant setup. If you need NG, choose the NG version of this product.
Where should it be installed?
This A-Series unit is designed for external installation. Placement needs to meet clearance and ventilation requirements and comply with relevant standards and manufacturer instructions.
Mains Power Requirement
This Rinnai Infinity A-Series model does require a 230V mains power supply to operate. Electrical power is used for electronic ignition, controls, and temperature regulation.
For off-grid properties, this is typically supplied via a suitable inverter or generator capable of providing a stable 230V output. Power consumption is low, but a continuous and reliable supply is required.
If you’re unsure whether your power setup is suitable, please contact us before purchase.
How do I choose the right size?
Size depends on household size, number of bathrooms, and whether you expect simultaneous hot water use. If you tell us your setup (baths/showers/outlets and how many people), we can point you to the most suitable option.
