Plan – Heat pump
Add a subsidy line (KfW) to the offer
Show the customer the expected grant, typically the KfW heat-pump subsidy in Germany, as a deduction on the offer.
Capture the existing heating and consumption
Record the customer's current heating system and its yearly consumption so the profitability comparison shows the heat pump against what they pay today.
Heat load indication
Decide whether building-envelope heat-load indication is the right sizing method — a real heat-pump sizing basis without running a full room-by-room scan.
Run a room-by-room heat-load calculation
Walk through every heated room of the building, validate walls, windows, radiators, and materials, run the DIN-EN-12831 calculation, and generate a report you can use for hydraulic balancing, radiator swap, and KfW funding.
Simple simulation (heat load)
The fastest of the three heat-load methods. It captures base building data and returns a simulation; use the deeper methods when you need a real sizing basis.
Add a heat pump to the offer
Attach a heat pump from your catalog to this offer, then add storage and heating-rod components as needed.
Size the heat pump (dimensioning table)
Size the heat pump against the building's heat load. The cold-weather handover point to the backup heating rod — the *bivalence temperature* — is set on *More settings*, not here.
More settings
Set the planned installation date and bivalence temperature for the heat pump on an offer.
