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 24L unit support?

In most homes, 24L is ideal for one to two bathroom setups with normal household overlap. Real-world performance depends on incoming water temperature, pipework, shower heads, and whether multiple 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.
