As the originator of China's bathroom heating equipment, AOPU developed the first three-in-one bathroom electric heater for heating, lighting and ventilation in China, and named it "bath bomb". Aopu is a leading enterprise in this field and participated in the formulation of the national standard for bath bombs as the main drafting unit. From 2001 to 2014, Aopu occupied the first place in the domestic bath bomb market for 13 consecutive years.
 
AOPU mainly uses air heating type, and has a small number of lamp heating and double heating products. The price of air heating is between 700-3000 yuan, and the low-end series is equipped with a single nuclear power engine, with a compact fuselage structure and low operating noise. The high-end model is equipped with dual nuclear power engines, supports independent operation of ventilation and heating, and provides a drying effect when used together, which is enough to cope with the rainy and humid weather in the south, and the price of these models is high, such as bath MAX series QDP6026 and QDPX6526 are priced at 2499 yuan and 3999 yuan respectively.
 
AOPU has done a particularly good job in electrical overheating protection. The national standard requires the air heater to set a temperature extreme, and when the temperature of the PTC component exceeds this value, the power supply will be cut off by itself. At the same time, when the internal temperature of the fuselage reaches 65°C, the PTC element will stop heating, and the temperature of the fuselage will continue to work after the temperature of the fuselage decreases to a certain extent. The design not only provides more effective safety protection, but also saves energy by eliminating the warm-up time after reopening the product.
 
Rich functions are also a highlight of Opple. In addition to the common wireless remote control, real-time temperature display and other configurations, AOPU also involves functions such as automatic bathing, two-stage dimming, and remote control. In recent years, the bath MAX series QDP6024BS has been launched, with automatic bathing and remote control, the built-in sensor can sense the indoor temperature, after turning on the automatic bath, the bath bomb will switch between ventilation and air heating mode by itself due to indoor changes, without manual operation. Remote control is often used for preheating, and the practical type is average. The price of this model is 1399 yuan, which is cost-effective.
 
If the bathroom space is not large, you can consider the classic series QDP2218A, with a heating power of 1700W, a 10W lighting in the center of the panel, and complete basic functions. 2218A adopts ordinary ceiling, suitable for most roofs, the body weight is about 4.2kg, gypsum board and wood board ceiling can bear load, the opening size is 300×300mm, which belongs to the common ceiling size, new installation and replacement are very convenient, the current price is about 1150 yuan, is quite economical and practical model.
 
The warm type of the lamp of Aopu adopts NBSS bulb, the shell is a No. 11 hard explosion-proof glass with strong thermal stability, and the filament is made of double spiral tungsten filament, which emits a low color temperature of the light, soft and not dazzling. In the explosion-proof test, its reliability is higher than the 5 (±1) °C cold water shock required by the national standard. The evergreen FDP5010D is equipped with four NBSS bulbs, two-stage temperature control, and a long rocker switch, which can be operated with wet hands and high safety. However, the warm time of the lamp should not be too long, and the bathing time should be controlled when using.
 
In terms of installation, Aopu has a complete range of models, the product line covers ordinary ceilings, integrated ceilings and wall-mounted products, among which the air heating is mainly installed in the ceiling, the size specifications are 300×300mm, 300×600mm, the installation cost is 50 yuan, the lamp heating has both ceiling and wall hanging two installation methods, considering that some old houses have no ceiling, the wall structure is easy to loosen, it is recommended to use wall-mounted lamp heating. It should be reminded that the bath bomb is a high-power product, and it needs an exhaust duct, which is much more difficult to install than the lighting category, so it is best not to install it yourself. Before purchasing, you need to measure the height of the mezzanine between the ceiling and the roof to determine whether the bath bomb is allowed to be installed, and you need to reserve ventilation openings, and if it is an ordinary suspended ceiling, you also need to prepare fixing materials.
