Can the system handle high demand when the property is full?

Yes. Every 100UP system is sized for maximum occupancy — not just who’s living there today.

The 100UP Way: 5 kWh for the house, plus 5 kWh per person by bedroom capacity. A 4-bedroom install is engineered for up to eight people — heating, hot water, cooking, appliances running together.

That covers family visits, Airbnb guests, changing household size, and resale — a buyer isn’t inheriting a system that only worked for two people.

Full house, full load — that’s the scenario we design for.
