Advantages and disadvantages of gas, coal and hot water equipment: gas water heater biggest advantage: popular, as long as a few hundred dollars you can install! Disadvantages: not environmentally friendly, easy to be poisoned by improper use! There is the risk of explosion. Advantages and disadvantages of solar hot water + electric auxiliary equipment: 1) Solar water heaters: The main advantage: the weather is sunny, hot water free of charge; main drawback: rainy days without hot water, little water pressure, summer and winter too little, controller easy bad; in fact, the solar water heater must configure the "Power-assisted", otherwise can not be used in winter; secondly, because the solar hot water heaters can be up to 100 ℃, and the temperature difference between the cold water, bathing in the bath, the others can not be used hot or cold water, because once the use of hot or cold water, the water pressure will change, there will be "hot and cold" phenomenon, sometimes even a "hot man" situation. (2) Water Heater: The main advantage: at any time can be used for hot water; Disadvantages: costs of electricity, water less, may be a shock, take up interior space, installing multiple units; electric heaters waste electricity we all know, a electric water heater consumes 10 kWh of electricity a day; less water reserves is its weakness, under normal circumstances, the next bather to wait half an hour; if the water heater capacity expansion, it is very occupied interior space, and the bathroom The area itself is not large, it will seem crowded; electric water heaters require periodic renewal is for security reasons, are prone to leaking old appliances we all understand, once the water heater leakage, it will directly cause death; relative solar water heaters, electric water heater "hot and cold" phenomenon better, though not "hot people", is very uncomfortable. Advantages 武汉胜 Hao air source heat pump water heating equipment energy-saving: General Xianning hotels large amount of water, but we set a ton of water heating costs is between 7-15 yuan. Security: a full range of security protection: overpressure, overtemperature, press overload, phase sequence, antifreeze, use of worry. Control: All intelligent microcomputer control system, the user can optionally operate, no special care. Environmental protection: no emissions, no pollution, low-carbon environment. Quiet: conduct damping process, low speed winds fan the amount of work for you to create a good and comfortable environment. Katsuhiro engineering machine 9 core strengths 1. Siemens control of the control unit by Germany's Siemens components, more secure and reliable. Control of water projects are intelligent operation. In order to ensure the accuracy of control and can protect the legitimate operation of the device, and effectively extend the life of the equipment. 2. High-performance compressor heat pump compressor is the "heart", Katsuhiro the best use of technology dedicated compressor heat pumps - United States, "Copeland" smart scroll compressor, the service life of up to 20 years. 3. coaxial tube heat exchanger domestic hard water, water ca +, mg + ion content, will be difficult to peel off after the formation of heat scale attached to the inner wall of the heat exchanger, seriously affecting the efficiency of heat transfer. Katsuhiro Technology avoids time problems using coaxial tube type efficient heat exchanger. The German ultra-low temperature technology DHW Germany's ultra-low temperature technology to work in more than -20 ℃ environment, especially for the Chinese complex climate. 5. Remote control from the heat pump system is not affected, comprehensive water monitoring system status, time to meet customer demand for hot water at different times. 6. The multi-stage energy absorbing system regulating energy adjustable, depending on the environment and use case, adjust the heating capacity of the system, more energy efficient and reliable. 7. power and memory use, such as a power failure, the unit based upon the original mode after the call, convenient worry. 8. Intelligent defrost technology DHW Germany's Intelligent defrost technology, the system automatically collect and determine the extent of the heat exchanger frost, defrost reasonable, to avoid the unit energy loss occurs due to frost-defrost. 9. COP value Katsuhiro Technology ultrahigh energy efficiency and reliable data, COP value close to 4.5 parts of engineering machine. Higher than the national standard closer to 20%. Air to water heaters use a very wide range, hotels, guesthouses, home, school, hospital, staff quarters, kindergartens, hospitals, barber shops, nursing homes, spas and the like.
