You also may have wondered just exactly how much you are paying for your shower or your bath. In addition to the actual cost of the water, the total cost of a litre of hot water depends on the kind of energy used (gas, electricity or solar) and on the kind of appliance you use.
As such, for every litre of hot water, you need to factor in:
The five most widely used appliances are:
The table below gives you an idea of the total cost of hot water for each appliance:
|Type||Cost per shower||
|Cost per bath||
|Instantaneous gas-fired water heater||0.356 €||519 €||0.806 €||1176 €|
|Dual purpose gas-fired heater||0.317 €||462 €||0.767 €||1119 €|
|Electric boiler||0.690 €||1007 €||1.030 €||1503 €|
|Thermodynamic boiler||0.550 €||803 €||1.060 €||1547 €|
|Solar boiler||0.520 €||759 €||0.790 €||1153 €|
Our calculations are based on the following parameters:
Lastly, the energy bonuses granted by Bruxelles Environnement may turn this hit parade on its head, making the solutions that are most expensive to start out with rewarding over time.
|Please note that these calculations only look at the cost element, not the ecological cost. The solar solutions are obviously most beneficial to the environment.|
