How to heat indoor heaters: principles, types and purchasing guide
With the arrival of winter, indoor heaters have become a must-have heating equipment for many families. This article will introduce in detail the heating principles, common types and purchasing suggestions of indoor heaters to help you choose a suitable heater.
1. Heating principle of indoor heater

Indoor heaters mainly convert electrical energy or fuel into heat energy, and transfer heat to the indoor space through different heat transfer methods (convection, radiation or thermal conduction). The following are common heating principles:
| Heating method | Principle | Applicable scenarios |
|---|---|---|
| Resistance heating | Electric current passes through the resistor to generate heat, and the heat is transferred through air convection or radiation. | Small space, local heating |
| Infrared heating | Direct heating of objects and human bodies through infrared radiation | Open space, rapid heating |
| heat pump heating | Using the reverse Carnot cycle principle, heat is absorbed from the outside and released into the room | Large area, energy saving needs |
| gas heating | Burning natural gas or liquefied gas to produce heat | Outdoors or in a well-ventilated room |
2. Common indoor heater types
According to the heating principle and design, indoor heaters can be divided into the following categories:
| Type | Features | Advantages and Disadvantages |
|---|---|---|
| electric heater | Resistance heating, small size, portable | Advantages: low price, easy to use; Disadvantages: high power consumption |
| Youting | Heat dissipation through heating oil medium, slow temperature rise but good heat preservation | Advantages: safe and stable; Disadvantages: bulky, long warm-up time |
| infrared heater | Directional heating, instant heat | Advantages: Quick heating; Disadvantages: Limited irradiation range |
| Heater | The heated air is blown by a fan | Advantages: Even heating; Disadvantages: Noisy |
3. How to choose an indoor heater
When purchasing a room heater, consider the following factors:
| Considerations | Description |
|---|---|
| Power | Generally, 1500W-2000W is selected for 10-20㎡ space. |
| security | Choose a model with dump power-off and overheat protection |
| Energy efficiency | Pay attention to energy efficiency levels and select first-level energy efficiency products |
| noise | For bedroom use, low-noise (<40 decibels) products are required. |
| Function | Consider additional functions such as timing, remote control, and constant temperature |
4. Precautions when using indoor heaters
1. Keep a safe distance: Keep a safe distance of at least 1 meter around the heater to avoid approaching flammable materials
2. Regular cleaning: especially the filters of heaters, clean them at least once a month.
3. Avoid long-term use: it is recommended to turn off every 4 hours to prevent overheating
4. Pay attention to ventilation: good ventilation must be ensured when using gas heaters
5. Child protection: Families with children should choose models with protective covers.
5. Recommendations for recent popular heater products
| Brand | Model | Features | price range |
|---|---|---|---|
| Beautiful | HFY20B | Graphene heating, intelligent constant temperature | 500-800 yuan |
| Dyson | HP09 | Heating and cooling, air purification | 4000-5000 yuan |
| Gree | NDY18-X6022 | Dumping and power-off, saving energy and electricity | 300-500 yuan |
Summary: Choosing a suitable indoor heater requires considering many factors such as space size, usage requirements, and safety performance. I hope this article helps you find the best heating solution during the cold winter months.
