Assumptions & Comments

• We assume your current standard shower uses 12 liters per minute.
• Your inlet water temperature is 10 degrees C.
• Your outlet water temperature is 60 degrees C.
• The amount of energy needed to heat 1 liter of water by 1 degree is equal to 1 kcal or 0,00116 energy. (Calculation based on the international unit system (IS). 
• The calculation of the CO₂ volume is based on the following: 1 kWh oil = 0.26 kg CO₂/1 kWh gas = 0.20 kg CO₂/1 kWh electricity = 0.60 kg CO₂
• *² 0,22 € is the EU-27 average price in the first semester of 2020 (a weighted average using the most recent (2020) data for electricity by household consumers) according to “Eurostat”. However, you can indicate your local price if known.
• This performance is based on the consumption measured over one year. However, the results may vary depending on external factors (sanitary installation, product assembly, etc.); for which Gjosa cannot guarantee the exact accuracy of the data.
