1. Oil-filled electric heater

Oil-filled heater is a kind of safe and reliable space heater popular in recent years. It is mainly composed of special heat conduction oil, metal heat dissipation shell, electric heating tube, thermal protection element, power supply board, display board , thermistors, temperature control components, power switches, work instructions, etc.; portable oil heater is generally welded from cold-rolled plates, equipped with anti-fall switches and components; Wall-mounted oil-filled heaters are generally made of cast aluminum heat-conducting shells. They are the optimal combination of radiation and convection heating methods. They are one of the main products of electric heating systems.

Advantages: The biggest feature of the oil-filled heater is that it has a large heat capacity. During the heat preservation period, it can still continue to heat the indoor air. Even if the power is suddenly cut off, it will maintain the temperature for a long time; no light, no oxygen consumption, odorless, and no harmful gas , No electrical running noise, low surface temperature, generally not more than 75-85℃, even if it touches the surface, it is not prone to burns. It is safe for the elderly, children, pets, it is suitable for heating needs of various indoor environments such as bathrooms, bedrooms, living rooms and offices.

The oil heater has a long preheating time and is not suitable for immediate use.

Disadvantages: The oil heater has a long preheating time and is not suitable for immediate use; the power is large and the energy consumption is high. If the filling is not good, it is easy to cause the solder joints to crack and leak oil, and the smell of oily smoke during work.

2. Aluminum convection room heater

Aluminum convection plate heater is aluminum shell, plate-type low-temperature heating body, surface heating, rapid formation of hot air curtain, thermal convection and far-infrared heat radiation, the unique internal cavity structure of aluminum plate heater, divides the air into uniform small chambers, can Effectively heat the air in the small cavity by fully conducting and radiating the heat energy, reducing the turbulence of the inner cavity, allowing the heated air to flow out quickly along the wall of the small cavity, improving the convection efficiency; low-temperature convection technology, natural, gentle, it doesn't need too much high temperature and does not make people feel too dry.

Advantages: The biggest feature of aluminum convection room heater is that it heats immediately when it is turned on, low temperature heating, energy saving and low consumption, high thermal efficiency, low surface and air outlet temperature, no light, no oxygen consumption, no smell, and no harmful gas , No electrical operating noise, it is suitable for heating in various indoor environments such as bedrooms, living rooms, offices, and commercial spaces.

Disadvantages: Cooling quickly, no heat storage, cold when shutting down, it needs to be turned on for a long time and kept at low temperature, if the product structure is unreasonable, there will be abnormal noise and affect sleep; If the heating body is configured unreasonably, the surface and outlet temperature will be too high, the convection effect will be poor, and the human body will feel hot.

3. Thermal inertia ceramic plate heater

Thermal inertia ceramic plate heater are generally made of magnesia brick, silicon carbide, and stone plates, which are glued, pressed or sintered into a block heating body by embedding electric heating resistors, and are equipped with aluminum heat dissipation shells or steel flat shells. Heater products with heat convection, heat radiation, or forced convection have a slow heating speed, but have good heat storage effects. They are more suitable for families with elderly and children at home. The ceramic plate heater is an efficient regenerative heater with uniform heat distribution. The metal alloy with excellent thermal conductivity ensures the uniform temperature of the hot surface and eliminates the hot and cold spots of the equipment.It has the advantages of long life, good heat preservation performance, strong mechanical properties, corrosion resistance, anti-magnetic field etc. It has the characteristics of non-oxygen consumption, non-oxidation, and non-dry mouth and tongue, and can deodorize and keep the indoor air fresh.

Advantages: Ceramic plate heaters are characterized by large heat capacity and good thermal inertia. In the heat preservation state, they can continue to output heat and continue to heat the indoor air. Even if the power is suddenly cut off, the output will remain for more than 1 hour; it is odorless and no harmful gases. No light, no oxygen consumption, no electrical operating noise. The surface temperature is low, and it is not easy to burn. It is safe for the elderly, children, and pets. It is suitable for the indoor heating needs of large spaces such as living rooms, living rooms, offices, and businesses. Wall-mounted use is more conducive to improving convection efficiency and is one of the core products of centralized electric heating.

Disadvantages: The ceramic plate electric heater is heavy, not suitable for moving use, and it has a long preheating time, slow heating, and is not suitable for short-term use when it is turned off and used in small indoor spaces; There will be a peculiar smell when used for the first time, and an unreasonable configuration will cause a dry feeling.
