Cost-effectiveness analysis: Carbon vs. heat pump

Start with a quick check (orientation) and, if required, request an individual cost-effectiveness analysis with upload (energy certificate/floor plan).

Note: The quick check is an orientation (bandwidths). For reliable values, we recommend the detailed inquiry.

Quick Check (Orientation)

Get a first assessment in 60 seconds: Electricity cost range & rough amortization at several electricity prices.

Living area (m²):

Energy standard (selection):

Electricity consumption carbon heating (kWh/year):

Space heating only (without hot water).

Electricity consumption heat pump (kWh/year):

If unknown: conservatively 300–700 kWh/a for very well insulated houses.

Additional investment heat pump (EUR):

WP incl. FBH/control/installation minus carbon system (typically €15,000–30,000).

Consider PV effect?

Typically, PV reduces the paid kWh difference.

For accurate analysis: Detailed inquiry

Result (range):

Electricity price	Additional consumption carbon vs. WP	Additional costs/year	Amortization (additional investment/WP savings)

Orientation: Simplified model. PV effect, user behavior, weather and system concept may vary. No funding commitment / no binding offer.
