How to choose the right heating method?
1. Metal heating tube
No matter what shape the electric heating tube is, it is inevitable to be immersed in water, and the contact area with water is only the surface area of the heating tube.
Advantages: low equipment cost, fast heating, high thermal efficiency
Disadvantages: low service life, poor safety after scaling, high failure rate, high maintenance frequency, need to match softened water
2. Non-metallic tube heating
The non-metal heating actually completes the separation of water and electricity, which improves the safety. At the same time, the problem of scale and power attenuation cannot be avoided.
Advantages: Moderate investment, good stability, separation of water and electricity
Disadvantages: slightly lower thermal efficiency, average energy-saving effect, and loud heating noise
3. Electromagnetic heating
A good heater, the water is magnetized during the heating process, the contact area between the magnetic wire and the container is large, which promotes the metal to heat itself, the heat is uniform, and the power does not decay during the basic use process. Currently, it is the most energy-saving and practical heater in the world.
Advantages: high thermal efficiency, stable machine, long service life, high safety, complete separation of water and electricity, no need for softened water
Disadvantages: high initial investment cost, complex control system, high requirements for power supply voltage stability
4. Photoelectric heating
The comprehensive heating tube is flattened, the glass tube is metallized, and the water and electricity are separated, which can effectively reduce the generation of scale and heat in all directions, which is better than other components in practical applications.
Advantages: Separation of water and electricity, never corroded and durable, completely eliminates potential safety hazards, overcomes scaling problems and control problems of electromagnetic heating
Disadvantages: high equipment investment cost, large shape, inconvenient installation
5. Air source heat pump heating
Use the heat energy in the air to heat the water, and use a small amount of electricity to collect and transport the heat energy in the air to the water. As long as there is air, it can be heated and provide hot water at 60°C.
Advantages: In the southern region, the thermal efficiency is as high as 300%, energy saving and high efficiency
Disadvantages: high investment cost, too much dependence on the environment, basically unable to operate in the northern winter, the compressor is easy to burn out under high temperature and high pressure, and the transportation process is vulnerable.
6. Plate heating
The use of high-quality resistance wire and thermal insulation material is fully enclosed heating, which not only ensures high thermal efficiency, but also ensures the separation of water and electricity, good thermal conductivity and long service life.
Advantages: reasonable investment, high thermal efficiency, separation of water and electricity, safe and reliable, long life
Disadvantages: The market is immature, the products are not common, and the after-sales service cannot keep up.
7. Cavitation hydrodynamic heating
This product is a brand new heat source equipment. Use liquid "cavitation phenomenon" to generate powerful shock waves and convert them into heat energy
Advantages: small size, simple structure, easy installation, long service life, liquid heating temperature up to 98 ℃
Disadvantages: The investment is too large, not suitable for small area heating
8. Coal-fired gas heating
Compared with the traditional heating method, the thermal efficiency is low, and the advantages and disadvantages of environmental protection and energy saving will not be explained. I believe everyone has a lot of opinions on this.
