Bosch Launches the New 20L Gas Water Heater Therm 5700

Take a Shower with Less Gas


  • Take a smart shower with plenty of water at a constant temperature
  • The breakthrough combustion technology sets a new trend for low-carbon and energy-efficient bathrooms
  • Multiple safety features give you the peace of mind when showering

Beijing — Bosch Thermotechnology recently launched a new 20L gas water heater – Therm 5700, for home use. Its design was inspired by Zugspitze, the highest peak of the Alps in Germany. As our “invented for life” slogan indicates, Bosch is committed to making our customers’ lives safer, more efficient and more comfortable through the innovations and services we supply. This fits in with the spirit represented by Zugspitze.

As a new product that is the most compact one among the 20L high-flow gas water heaters, Bosch Therm 5700 is extremely fastidious whether in terms of material selection or in terms of product structure. The glacier white body is simple but distinguished, whereas the flame-colored screen is warm and shining. This product combines the exceptional design philosophy with Bosch’s exclusive “magic technology” perfectly together to provide multiple safety features while allowing you to take a worry-free and comfortable shower with plenty of water at a constant temperature.

Since the first vertical gas water heater was born in 1894, Bosch Thermotechnology has been bringing Germany’s leading industrial designs, products, technologies and services to customers in more than 100 countries and regions around the world, and the brand has been praised by consumers for its professionalism and ingenuity generation after generation. Bosch Therm 5700 20L is low-carbon, efficient, safe and reliable with a high flow rate. It can meet the comprehensive needs of consumers.

Take an efficient and comfortable shower with this energy-efficient and low-carbon product

Bosch Therm 5700 20L comes with the sealed high-efficiency and enhanced burners, ensuring the complete combustion of gas, to reduce heat loss and save energy. Bosch’s exclusive smart segmentation technology supports the combustion of gas by three burners in two sections. The heater can automatically adjust water temperature based on the user’s needs, to avoid the unnecessary waste of gas. Thanks to the two energy-saving features, this product has an amazing thermal efficiency of 89%. It reduces the amount of gas used by 0.2m³ an hour compared to ordinary products, and can reduce carbon emissions by about 287kg a year. If you use the product for 8 years, you will be able to reduce carbon emissions by about 2,300kg, which is equivalent to planting more than 125 trees. While delivering solid benefits to consumers, this product can really save energy and reduce emissions from the very source. In this sense, it contributes to curbing climate change with technology and provides a great weapon for environmentalists.

Multiple hi-tech safety features give you the peace of mind

Bosch Therm 5700 20L is not just super energy-efficient. It also comes with multiple safety features, including the CO alarm, the forced-draft combustion system, the feature to avoid heating without water, and the antifreeze feature, to protect the user’s safety to the maximum extent possible. When the indoor CO level is above the standard, the detector would automatically activate the audible & visual alarm, immediately cut off the gas supply, and open the heater’s exhaust system to exhaust continuously to the outside until the concentration of harmful gases or combustible gases is reduced to the safe level. When it comes to electrical safety, gas safety or harmful gas monitoring, Bosch always attends to every detail, so that you and your loved ones can rest assured when taking a shower.

It’s like taking a shower of a five-star hotel style in a tropical forest

It’s worth mentioning that Bosch Therm 5700 20L adopts an advanced microcomputer smart control system, to automatically memorize the set temperature, and to produce up to 20L of hot water every minute, making this product the best choice for taking a comfortable shower. The proportioning valve controls the match between the pressurizer and the water flow servo valve, to ensure that water comes out at a constant temperature, and to avoid water temperature from becoming high at one moment and low at another due to unstable air pressure. The ultra-low water pressure activation feature enables people living in residential areas with a low water pressure to use the product on multiple spots of their home including bathroom and kitchen, so that they can take a comfortable shower at a constant temperature like in a five-star hotel. As the latest product of the large-volume Bosch water heaters, Therm 5700 20L is your best partner at home. This product is right for you whether you live with your parents or you already have your second child. It enables your entire family to enjoy an ultimate showering experience relaxed and worry free whenever you want it.
