Home / New Zealand guides / Site assessment / Equipment and service access: Compact apartment
New Zealand planning guidance for a specific property and load boundary. Ask about common-property consent and separation. H2OME remains in early development.
A proposed system needs a safe route for delivery, professional servicing and emergency response. Record gate widths, steps, occupied walkways and vehicle patterns for assessment. Think about the ordinary service visit as well as the initial placement of equipment.
Do not publish generic clearances or move equipment based on an online checklist. Required space and separation depend on the actual design and professional risk assessment. Everyday storage, vehicles and public access can change after installation, so the operating boundary needs an owner.
Cooking appliances, tumble drying and communal services are outside this illustrative essential load set.
Shared walls, common switchboards and building rules matter as much as the demand inside the flat. A resident does not control the lift, communal pump or fire systems simply because they can list their own appliances.
In a compact apartment, map the route used to check refrigerator, assumed time-averaged input separately from the service route for proposed energy equipment. Ordinary appliance access should not require entry to a restricted equipment area, even during the 6-hour base window.
Ask about common-property consent and separation. An apartment may be unsuitable for on-site hydrogen equipment. Do not infer suitability from low electricity demand; building permissions, safe separation and professional assessment come first.
All numbers below are hypothetical teaching inputs, not measured appliance specifications or product performance. The topic-specific extra load is separate from the base set; omit it if your real inventory already counts it. This worksheet does not include conversion overhead, protection design or a contingency allowance.
For a compact apartment, assume the selected base loads average 0.13 kW for 6 hours: 0.13 × 6 = 0.78 kWh. Separately, an additional service-area light draws an assumed 30 W for 2 hours: (30 ÷ 1,000) × 2 = 0.06 kWh. The combined illustrative demand is 0.84 kWh.
Lighting demand can be counted; the safe working arrangement still needs a professional assessment.
For arithmetic only, if the complete storage chain had a hypothetical 30% round-trip efficiency, delivering 0.84 kWh would require 0.84 ÷ 0.30 = 2.8 kWh of charging input. This is not a measured H2OME efficiency or recovery result. Ongoing demand during charging would add to the required input.
Base operating window: 6 hours. Extra illustrative load: An additional service-area light, 30 W for 2 hours. Replace every input with a measured or professionally established value.
In New Zealand, discuss supply arrangements and connection questions with your electricity retailer and distributor. Ask the local council about relevant siting, building and water-use requirements. Use appropriately qualified electrical and hydrogen professionals, and refer workplace safety questions to WorkSafe guidance. This page does not establish a consent or compliance outcome.
For medically dependent people in New Zealand, register with your electricity retailer, the company that bills you, and keep that registration current. Re-register when switching retailers; ask the retailer how the distributor is informed and what clinical confirmation is needed. Follow the clinician and equipment provider's contingency plan. Registration does not guarantee uninterrupted electricity, and H2OME is not a substitute for that plan.
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.
Hydrogen is an energy store, not free energy. Grid input, wind and micro-hydro are the charging options considered here. Each requires its own supply assessment. Do not install hydrogen equipment, modify fixed wiring, bypass protection or improvise a connection from this guide.
These official resources provide energy, consumer and technical background. They are not endorsements of H2OME, proof of its performance or a substitute for site-specific professional advice.

No. The 0.84 kWh total is an illustrative demand worksheet, not a runtime result. Actual appliance measurements, usable storage output, starting demand, conversion overhead and reserve limits are needed. The 10 kW design target is not demonstrated output capability.

Use the worksheet to brief the relevant professionals, not to install, modify or operate hydrogen equipment.
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.
