What is the Warmduscher Project?
The Warmduscher is a clever, retrofittable heat exchanger designed to recover up to 40% of the residual heat from shower wastewater and transfer it back to the incoming fresh water. Imagine… while you’re enjoying your shower, this device quietly captures heat that would otherwise be lost, making your hot water usage way more efficient. It’s super easy to install—no need for a contractor—so both homeowners and renters can jump on board. Plus, all Warmduscher products are crafted with minimal plastic, aiming for durability that lasts forever. In just about 10 minutes, you can have it set up and start saving energy.
Main Benefits of Using Warmduscher
Here’s the lowdown on why this heat exchanger is a game-changer:
- Recovers up to 40% of energy from shower wastewater
- Installation takes only 10 minutes—no professional needed
- Reduces hot water consumption by pre-heating cold water by 10-15°C
- Can save up to 100€ per person per year, especially with electric instantaneous water heaters
- Minimizes CO2 emissions by cutting down energy use during showers
- Made with as little plastic as possible for long-lasting use
- Flexible options available: Original model with bamboo cover, bathtub retrofit, and different lengths of fall pipe heat exchangers
How Does the Warmduscher Work?
The magic lies in its simple yet effective design. Cold water is diverted and passed through a heat exchanger where warm shower wastewater flows over it. This process heats the incoming cold water by 10 to 15 degrees Celsius before it even reaches the mixing valve. So, less hot water is needed to reach your perfect shower temperature. The water heater doesn’t have to work as hard, which means less energy consumption and lower bills. And since there’s no power connection or contact between fresh and wastewater, it’s safe and eco-friendly.
Different Models for Different Needs
Warmduscher offers a few tailored products to fit various setups. The Original model comes with a high-quality bamboo cover and is perfect for retrofitting existing showers. For those with bathtubs, there’s a flexible Warmduscher designed specifically for that. And if you want to install it in your fall pipe, the Showersave heat exchanger comes in different lengths to suit your plumbing. This variety means almost anyone can find a Warmduscher that fits their home and lifestyle.
Energy Savings and Environmental Impact
Showering is actually the second largest energy consumer in most households, and it generates a significant amount of CO2. The Warmduscher tackles this head-on by recovering heat that would otherwise go down the drain. By using this device, households can significantly reduce their energy consumption and carbon footprint. Plus, the savings add up over time—imagine saving up to 100€ per person every year just by installing this simple gadget. It’s a win-win for your wallet and the planet.
