Saving water is a necessity, but also an opportunity. With devices like Acqua Tempus, you not only care for the planet, but you can also significantly reduce your water and gas bills.
Now, one of the most common questions among those thinking about installing it is:
💡 How long will it take to recover my investment?
In this article, we explain how to calculate the return on investment (ROI) of Acqua Tempus, with real-life examples for homes, vacation apartments, and hotels.
ROI (Return on Investment) measures how long it takes to recover what you paid for a device thanks to the money you save with it.
Formula Basic:
ROI (in months) = Cost of the device / Monthly savings obtained
For example, if Acqua Tempus costs €180 and saves you €20 per month between water and gas, your ROI would be 9 months.
According to data from the INE and Aigües de Barcelona:
In addition, around 60% of the energy cost of the hot water is spent heating it. That is, you're not only paying for water, but also for energy or gas.
| Type of expense | Average per shower | Monthly cost (2 showers per day) |
|---|---|---|
| Water | €0.07 | €4.20 |
| Energy (heating water) | €0.25 | €15 |
| Total | €0.32 | €19.20 € |
(Estimated figures based on average household rates for 2025)
Acqua Tempus is a smart shower timer that automatically turns off the water when the maximum set time is exceeded.
For example, you can limit your shower to 5 minutes, which means:
And best of all: without affecting user comfort. Ideal for both family homes and vacation homes or gyms, where controlling consumption is more difficult.
Monthly savings: approximately €18–20.
Device cost: ~€180.
Payback: 9–10 months.
Monthly savings: €12–15.
Payback period: 12–14 months.
Furthermore, the savings are greater if you have an electric water heater, since hot water is more expensive to consume.
€3 per day = €90 per month per shower.
If you install an Acqua Tempus (€180 per unit), you'll pay for it in just 2 months.
From there, it's all about sustained profit and savings.
In addition, it helps comply with water and energy efficiency policies, which are increasingly valued in sustainable accommodations and communities.
Installing an Acqua Tempus is one of the fastest and most effective ways to:
💧 In most cases, it pays for itself in less than a year, and from then on, it only generates savings.
