Geothermal Heat Pump
Ground exchange & COP. This multi-solver chains 2 solvers into a single guided workflow — run each step in order and carry the result forward.

Presets
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.

Presets
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.

Frequently asked questions
- What is the Geothermal Heat Pump multi-solver?
- Geothermal Heat Pump is a guided workflow that chains 2 individual PolySim solvers into one end-to-end analysis, piping each result into the next step.
- Is it free to use?
- Yes. Every step runs entirely in your browser using real numerics — no install, no account, no cloud cost. Custom or private solver packs are available as a paid service.
