Petite Source's Electrical Consumption

As Petite Source is a responsible choice, it is economical in its water usage as well as its overall consumption, particularly electrical.

In the interest of transparency and clarity, here is a detailed calculation of Petite Source's electrical consumption cost.

 

Units reminder:

• Cost per kWh ~€0.25 (January 2024)
• 1 MWh = 1000 kWh
• 1 kWh = 1000 Wh (1 Wh = €0.00025)

 

Interior LED Lighting

The consumption of the LED color spotlight inside the pool is 10 Wh.

Electricity consumption calculation details:

10 Wh x €0.00025 x 24 h x 30 days = €1.8

For maximum usage, 24 hours a day over 30 days, the cost is €1.8.

 

Exterior LED Lighting

The consumption of the exterior color LED lighting is 19.2 Wh per linear meter (lm).

The perimeter of Petite Source is 8.6 m.

Electricity consumption calculation details:

8.6 lm x 19.2 Wh x €0.00025 x 24 h = €1 for 24 hours of lighting.

The exterior lighting is useful during nighttime periods. Therefore, for an average usage of 5 hours per day, the monthly cost of this lighting is €6.

 

Filtration Pump

Consumption: 180 Wh.

Electricity consumption calculation details:

180 Wh x €0.00025 x 24 h = €1.08 per day.

For maximum usage, 24 hours a day over 30 days, the cost is €32.

 

Electric Heater

Consumption: 2000 Wh.

Electricity consumption calculation details:

2000 x €0.00025 = €0.5 per hour

€0.5 x 12 h = €6 for a half-day.

 

Heating Up

On average, it takes 12 hours to raise the water temperature from 18 °C to 34 °C under the following conditions:

• with a foam cover
• ambient temperature of 18 °C
• no wind
• no sun

12 h x €0.5 = €6 + €0.50 (pump consumption) for heating up.

 

Electrical Consumption Table

To provide a concise and readable estimate of Petite Source's electrical cost, here is a table presenting various scenarios based on different durations and geographic locations.

You can read the detailed explanations of this table below.

To create this table, the following two factors were analyzed and considered:

1. the location of Petite Source's installation;
2. the usage period of Petite Source.

Note: In all cases, it is highly recommended to keep the foam cover on at all times for two main benefits:

• to maintain the water temperature;
• to prevent evaporation (essential in enclosed spaces).

 

Installation Location

Indoor Installation

Installing Petite Source indoors removes climate-related factors from the consumption calculation since the ambient temperature will in theory remain constant.

This environment, protected from cold and wind, is considered "favorable" in the summary table above.

 

Outdoor Installation

Outdoor installation of Petite Source involves considering various factors to calculate its electrical consumption.

Geographic area (country, region, department), exposure to wind and sun, altitude… Based on these conditions, we have defined 4 hypothetical outdoor environments from “favorable” to “extreme,” explained below.

Usage Period

Petite Source can be used year-round or during specific periods throughout the year (long weekends, school vacations, summer months, etc.)

 

Here are some hypothetical electrical consumption scenarios for water at 33 °C:

• Heating up ~€6.5 (see above).
• Filtration time for water at 33 °C is 24/7, costing approximately €1 per day.
• Maintaining the water temperature at 33 °C: the pump runs continuously, while the heater operates only to compensate for a drop of 0.5 to 1 °C. External environment conditions are therefore highly influential. We have studied the following 4 scenarios to help you anticipate Petite Source's operational cost.

 

Favorable Environment

Ambient temperature of 25 °C or higher with partial or full sunlight.

The heater will run from 0 to 3 hours a day. Assumed value: 1.5 hours of heating, or €0.75.

Daily cost (24h): ~€1 for the pump + €0.75 for heating = ~€1.75

 

Moderate Environment

Ambient temperature between 18 °C and 25 °C with partial sunlight.

The heater will run 3 to 7 hours per day. Assumed value: 5 hours of heating (€0.5/h) or €2.5.

Daily cost (24h): ~€1 for the pump + €2.5 for heating = ~€3.5

 

Unfavorable Environment

Ambient temperature between 10 °C and 17 °C with no sunlight.

The heater will run 7 to 11 hours per day. Assumed value: 9 hours of heating (€0.5/h) or €4.5.

Daily cost (24h): ~€1 for the pump + €4.5 for heating = ~€5.5

 

Extreme Environment

Ambient temperature 0 °C with no sunlight.

The heater will run 11 to 21 hours per day. Assumed value: 16 hours of heating (€0.5/h) or €8.

Daily cost (24h): ~€1 for the pump + €8 for heating = ~€9

 

Conclusion

Between the installation location, usage periods, and the four scenarios for maintaining the water temperature at 33 °C, it is clear that only a case-by-case assessment will accurately determine the electrical consumption of Petite Source.
