Separate food, water, heating and communication needs from loads that can wait.
The 6 topics below use ten different property contexts. Select the setting whose operating boundary matches your situation, rather than assuming a whole-property rating from a small appliance example.
H2OME is in early development. Its 10 kW output figure is a design target, not a proven specification. There is no confirmed price, certification, commercial availability or guaranteed runtime in this guide.
In Australia, check connection questions with your electricity retailer and distributor. Use electrical professionals holding the licence required in your state or territory, and ask the local council about relevant siting, building and water-use requirements. Energy Made Easy covers New South Wales, Queensland, South Australia, Tasmania and the Australian Capital Territory; outside those jurisdictions, check the relevant state or territory consumer energy comparison resource. Compare your actual tariff and charging window, not an assumed national rate. This guide does not claim to know a particular state's approval process.
Refrigeration demand varies with cabinet size, door openings, loading and room conditions. The electric supply is only one part of food protection; temperature records, safe handling and a decision about disposal remain important when operation has been interrupted. Measure each appliance rather than assuming two refrigerators use the same energy.
A pump-backed water supply needs both an electrical survey and a water reserve survey. Measure running input, controller demand and the typical time needed to replenish the pressure tank. A water tank can decouple the timing of pumping from the timing of household use, but only if its usable volume and water quality are known.
Some on-site wastewater systems depend on pumps, aerators or controllers. Their required schedule is determined by the system design and servicing instructions, not by a generic household backup checklist. Obtain the existing documentation and ask the service provider which functions can pause and which need continuity.
List the full connection chain: router, optical terminal if present, handset base, mobile charging and any local network equipment. A battery in a laptop does not power the router, and a powered router does not guarantee that upstream infrastructure or a mobile cell site is operating.
Electrical heating can dominate an essential-load set. Record the equipment type, operating input and which occupied room genuinely needs heating. Heat-pump performance and demand depend on conditions; a brochure efficiency figure is not a guarantee of the power draw in a particular outage.
Where medical equipment depends on electricity, the clinical contingency plan comes first. Ask the clinician and equipment provider about required supply quality, supported backup arrangements, alarms and when to move to another location. Do not infer a safe operating period from an appliance label or a household calculation.
Ask us about H2OME, tell us about your property or register your interest in the proposed system. We are in early development. No payment or purchase commitment; contacting us does not guarantee a pilot installation.
