New: Three Mini Calculators for Quick Calculations
Three new mini calculators are now available on pv-calor.com. These focused tools deliver quick results for specific calculation tasks – without project creation and with minimal input.
What Are Mini Calculators?
Mini calculators are tools focused on a specific calculation. Unlike our full calculators (heat load calculator, heat pump calculator, solar calculator), they skip extensive input forms and deliver results immediately.
Ideal for:
- Initial estimates before detailed planning
- Single rooms instead of entire buildings
- Quick verification of estimated values
- Simple calculations without registration
The Three New Mini Calculators
1. Room Heat Load Calculator
The Room Heat Load Calculator calculates the heat load of a single room according to DIN EN 12831-1. It determines the required heating capacity for sizing radiators or underfloor heating.
| Input | Output |
|---|---|
| Room area and height | Transmission heat losses |
| External walls and windows | Ventilation heat losses |
| Building age / insulation standard | Reheat allowance |
| Adjacent rooms | Total heat load in Watts |
Typical applications:
- Radiator sizing during renovation
- Checking existing heating surfaces
- Quick estimate for a single room

2. PV Yield Calculator
The PV Yield Calculator calculates the expected annual yield of a photovoltaic system. Based on real PVGIS satellite data, it provides a location-accurate forecast.
| Input | Output |
|---|---|
| Location (postal code) | Annual yield in kWh |
| System power (kWp) | Specific yield (kWh/kWp) |
| Orientation and tilt | Monthly yield distribution |
Typical applications:
- Initial estimate before quote preparation
- Comparing different roof surfaces
- Plausibility check of installer quotes

3. Consumption-Based Heat Load Calculator
The Consumption-Based Heat Load Calculator determines a building's heat load from actual energy consumption. Instead of extensive building surveys, the annual consumption of gas, oil, or pellets is sufficient.
| Input | Output |
|---|---|
| Energy source (gas, oil, pellets, district heating, electricity) | Heat load in kW |
| Annual consumption | Full load hours |
| Building area | Specific heat load (W/m²) |
| Location (postal code) | Degree hours from PVGIS climate data |
Typical applications:
- Quick heat load estimate before heat pump planning
- Plausibility check of calculated heat loads
- Comparison with standard calculation per DIN EN 12831

Mini Calculators vs. Full Calculators
| Criterion | Mini Calculator | Full Calculator |
|---|---|---|
| Input effort | Minimal (5-10 fields) | Extensive (many rooms/details) |
| Accuracy | Good approximation | Standard-compliant precision |
| Project creation | Not required | Optional with saving |
| PDF export | Not available | Available |
| Multiple rooms | Single room | Any number |
| Recommendation | Initial estimate | Detailed planning |
