Fraction of Carnot

A heat pump does not make heat — it moves it, so it can deliver several kilowatts of warmth per kilowatt of electricity. The coefficient of performance is that ratio, capped by the Carnot limit T_hot/(T_hot − T_cold). The colder it gets outside, the harder the pump works and the lower the COP — but even at freezing it beats a resistance heater several times over.

▶ Run in Python

Data Inspector

COP7.74

Carnot max COP15.5

Heat per kW power7.7 kW

vs resistance heater7.7× better

Governing equation

COP_{Carnot} = \frac{T _{h}}{T _{h} - T _{c}} = \frac{294.1}{294.1 - 275.1} = 15.5

Reading this result: At 2°C the pump delivers about 7.7 kW of heat per kW of electricity — roughly 7.7× a resistance heater — because it moves heat rather than making it.

Heat flows through a wall like current through resistors in series. Each layer's thermal resistance is its thickness over its conductivity; adding them gives the total R-value, and the heat flux is the temperature difference divided by it. Insulation, with very low conductivity, dominates the R-value — the steep temperature drop shows where it does its work.

▶ Run in Python

Data Inspector

Total R-value2.71 m²K/W

U-value0.37 W/m²K

Heat flux9.6 W/m²

Governing equation

R = \sum \frac{L _{i}}{k _{i} A} = 2.71 \frac{m ^{2} K}{W}, Q = \frac{Δ T}{R} = 9.6 \frac{W}{m ^{2}}

Reading this result: The insulation layer carries the most thermal resistance, so the temperature falls most steeply across it. A total R-value of 2.71 m²K/W lets 9.6 W/m² flow for this 26°C difference.
