Heat Pump Selector

Which heat pump fits your project?

Start from a known design heat loss or run a quick preliminary screening. The tool compares the result only with verified technical model data available in our catalogue.

Step 1

Project inputs

If you already have calculated heat loss, use it. Otherwise the tool returns a screening range from heated area and building-envelope category.

Project inputs
Approximate net heated floor area in m².

Not an “AI guess”Deterministic engineering bands and transparent constraints.
Verified catalogueCandidate models come from published catalogue technical data.
Human final checkFinal selection follows review of the actual project.
Existing radiator retrofit: Keeping existing radiators? Screen their output at lower water temperature first. Open Radiator Checker
Buffer tank or hydraulic separation? Check active water volume, zone closure, multiple pumps and mixed-temperature circuits without applying a universal litres-per-kW rule. Open Hydraulic Precheck
