How much heat does the home need?
Heat-loss forecasting
Thermal intelligence
A heat pump isn't a battery.
A home is.
Behind every heat pump is a system of pipes, floors, buffers and a building that retains heat. That's why we don't just control the device, but understand the thermal whole around it.

The invisible thermal battery
The biggest battery in the house sometimes isn't mounted on the wall.
An ordinary battery tells you exactly how much energy it holds. A home doesn't: it only reveals its state through temperatures, behaviour and time. Strooom continuously estimates that state, so we know how much heat is already stored and how much more can be added.

Five thermal questions
From physics to responsible flexibility.
Before shifting capacity, the Engine answers five questions about the thermal system. Only once those answers hold true do we know how much load can safely move right now.
How much heat is stored right now?
Building, floor, water and buffer
How fast does the home cool down?
Temperature decay over time
How fast does comfort recover?
Recovery curve and system response
How much load can shift right now?
Comfort-safe available flex
That's thermal flexibility: shifting heat in time, without anyone noticing.
Comfort limits
The resident notices nothing. The energy system does.
Within the resident's comfort preference, the Engine can heat slightly earlier when energy is cheap or clean, and pull back capacity when the grid or price calls for it. The temperature always stays within the range the resident has set themselves.
