One dwelling's radiators, fed from a plant across a water coupling. It is a single component and that is the point: a radiator is rated, not modelled — the EN 442 output at 75/65/20 °C and a characteristic exponent, with no geometry. Twelve kilowatts at that rating carries a 2.6 kW flat on 40 °C water, which is the low flow temperature a heat pump wants. That four-to-one multiple is the whole cost of a low-temperature retrofit: the same flat on a 70 °C boiler needs a third of the radiator. Published as an example; the figures below are solved from this model.

Solved from this example's own model each time the page loads — the same numbers a supplier's page shows for their machine.
