Pretty sunny here too, but still wouldn't come even close to breaking even for us
Yep. There are even stronger shower heads with up to 8800 W of power afaik, but they are not very common. Mine's on the stronger end, they are usually around 6500 W most of the time. This is assuming they are 240 V models, the ones that run on 127 V have amperage requirements blown through the roof and usually do not go above 5400 W. The current is extremely high.
There is a dedicated breaker just for the shower itself, separate from the rest of the installation.
I'm actually really curious now, how much does it cost in USD (if you don't mind doing the math and currency conversion) to take say a 7 minute long hot shower there?
In summer time I actually have no issue taking cold showers, its invigorating after being outside in the heat. In winter I need a hot shower though.
chatgpt says it only costs 15 cents total... so that's not right... thanks for nothing AI..
here is the prompt I gave chatgpt:
Assuming you have a shower head that uses 8000 watts of power, how much would it cost to take a hot shower for 7 minutes in rio de janero brazil, then convert the currency to USD.
and here is the answer:
To calculate the cost of taking a hot shower for 7 minutes in Rio de Janeiro, Brazil, we need to follow these steps:
1. **Determine the energy consumption in kilowatt-hours (kWh)**:
- Power consumption of the shower head: 8000 watts (8 kW).
- Duration of the shower: 7 minutes.
- Convert minutes to hours: 7 minutes = 7/60 hours.
2. **Calculate the energy consumption**:
\[
\text{Energy Consumption} = \text{Power (kW)} \times \text{Time (hours)}
\]
\[
\text{Energy Consumption} = 8 \text{ kW} \times \frac{7}{60} \text{ hours} = \frac{56}{60} \text{ kWh} \approx 0.9333 \text{ kWh}
\]
3. **Find the cost of electricity in Rio de Janeiro**:
- The cost of electricity in Rio de Janeiro is approximately BRL 0.80 per kWh.
4. **Calculate the cost in BRL**:
\[
\text{Cost in BRL} = \text{Energy Consumption} \times \text{Cost per kWh}
\]
\[
\text{Cost in BRL} = 0.9333 \text{ kWh} \times 0.80 \text{ BRL/kWh} = 0.74664 \text{ BRL}
\]
5. **Convert the cost from BRL to USD**:
- The exchange rate is approximately 1 BRL = 0.20 USD (this rate can fluctuate, so it might be different at the time of calculation).
6. **Calculate the cost in USD**:
\[
\text{Cost in USD} = \text{Cost in BRL} \times \text{Exchange Rate}
\]
\[
\text{Cost in USD} = 0.74664 \text{ BRL} \times 0.20 \text{ USD/BRL} = 0.14933 \text{ USD}
\]
Therefore, taking a 7-minute hot shower in Rio de Janeiro, Brazil would cost approximately USD 0.15.
