FAQ

Can I run this from bottled LPG (45kg bottles)?

Yes — this model is commonly installed on standard 45kg LPG bottle setups used throughout New Zealand. Your licensed gasfitter will ensure the correct regulator and line sizing are used for your installation.

Does this unit need electricity to run?

Yes — it requires a standard 230V supply for ignition and controls. Power use is low and in most off-grid homes this is easily supplied by an inverter or generator. If you tell us what power system you’re running, we can sanity-check it before you buy.

How many bathrooms can a 26L unit support?

For most homes, 26L 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.

Where should it be installed?

This A-Series unit is designed for external installation. Placement needs to meet clearance and ventilation requirements and follow manufacturer instructions and NZ standards.

Installation & compliance

This appliance must be installed in accordance with New Zealand regulations and is typically installed by a licensed plumber or gasfitter. Requirements can vary by site and council/insurer expectations — contact us if you want a quick suitability check before purchase.

Want us to size it properly? Tell us: number of bathrooms, how many people, and whether you expect simultaneous showers + kitchen use.
