Bosch from Germany is the world's largest supplier of automotive technology and has a strong reputation in a wide range of sectors, including industrial technology, consumer goods and energy. In the field of household appliances, Bosch Home Appliances is one of the home appliance brands with the highest market share in Europe, and in 2014 it acquired the home appliance business of Siemens. Bosch has been involved in the Chinese market since 2000 and has now expanded its business scope to major cities across the country, with several large-scale production sites.
 
The wall-hung boiler can be divided into two types: conventional wall-hung boiler and condensing wall-hung boiler, the latter has more than the former with a set of efficient heat recovery system, and adopts the full premix ratio adjustment method, so as to recover and utilize the waste heat in the flue gas, which is energy-saving and environmentally friendly. The newer Bosch conventional wall-hung boilers include the Gaishi 7000, the New Eurostar and the European Elite MINI series, with a thermal efficiency of more than 90%, compared with most conventional wall-hung boilers, Bosch products can convert gas into more heat per unit of time, which has the advantages of energy saving and environmental protection, and at the same time effectively controls the noise of the machine operation, so that people are not disturbed. In addition to the conventional models, Bosch also focuses on three series of condensing wall-hung boilers: European Aristocracy, European Classic, and European Perfection, all of which have a thermal efficiency of more than 100% and harmful emissions that reach the highest European standard of Class 5.
 
The L1P20-G7000W 24KW in the Gasgoo 7000 series is a cost-effective dual-purpose furnace priced at 8600 yuan, which can be used as a heating appliance and can also supply domestic hot water at a constant temperature. In addition to the elegant and stylish appearance, the L1P20-G7000W limits energy consumption to a controllable range, with a thermal efficiency of 93%, and provides two modes of energy saving/comfort, which is convenient for users to switch to the most suitable temperature with one click.
 
It is also a household dual-purpose furnace with outstanding performance, and the price of the original imported new Eurostar WBN6000-24 C is lower than that of L1P20-G7000W 24KW. Compared to the previous Eurostar wall-hung boiler, the new Eurostar has expanded the supply range of domestic hot water, but it has not been optimized too much in terms of noise control and heating temperature range. This product is known for its superior thermal efficiency, especially at partial load, which allows it to save about 10% of fuel compared to ordinary products, and the operation interface adopts an atmospheric and soft LCD screen.
 
Even consumers who are new to wall-hung boilers must have heard of the wall-hung boiler type of "plate exchanger". Compared with another type of casing wall-hung boiler, the plate exchange machine realizes the heat exchange process between heating water and domestic hot water through the plate heat exchanger, which has the advantages of stable water temperature, not easy to scale, convenient maintenance and replacement, and the thermal efficiency is higher than the former. The New Eurostar WBN6000-24 C is such a plate changer that provides instant hot water, with a compact and space-saving all-in-one design for a comfortable and convenient experience, and the core component is an imported SIT gas valve, which is superior to ordinary products.
 
The price of the condensing wall-hung boiler is much more expensive than the regular model, and the price of the Bosch European aristocratic ZWB35-3A23 is more than 20,000 yuan, which is suitable for large apartments or villas. With the application of advanced condensing technology, the thermal efficiency of European nobles can reach 106%, meeting the national level 1 energy consumption standard. Its unique WB5 heat exchanger is made of aluminum-silicon alloy and manufactured by sand casting process, which can easily meet daily needs with compactness and corrosion resistance, supplemented by high-strength fin design, so that the heat exchange area has been increased to a large extent.
 
All of its products are controlled to operate below 38 decibels, and the quiet performance is the top level in the industry.
