After entering autumn, the demand for heating equipment in households gradually increases, and fully premixed condensing wall mounted boilers have attracted the attention of many consumers due to their energy-saving and high-efficiency characteristics. However, there are many types of fully premixed condensing wall mounted boilers on the current market, and many people often feel confused when choosing a fully premixed condensing wall mounted boiler due to the complexity of information, not knowing which aspects to start from. In fact, as long as you master a few key points, you can more clearly avoid common problems in purchasing and find a fully premixed condensing wall mounted boiler that is suitable for your own use and cost-effective.
1、 Prioritize core performance to ensure heating and hot water experience
The core performance of the fully premixed condensing wall mounted boiler directly affects the daily user experience, which is also the primary consideration when purchasing. This can be discussed from two dimensions:
1. Combustion efficiency: Identify the advantages of high condensation technology
The core competitiveness of fully premixed condensing wall mounted boilers lies in the "condensation" technology, and high-quality products can improve combustion efficiency by recovering heat from flue gas. When making a purchase, it is important to focus on the thermal efficiency value of the product. Fully premixed condensing wall mounted boilers that meet national standards usually have a thermal efficiency of over 90%, and some high-quality products can even exceed 105%. It should be noted that true full premixed technology can fully mix gas and air in advance, reduce harmful gas emissions, and avoid energy waste. Long term use can significantly reduce gas costs.
2. Temperature control accuracy: adapted to different scene requirements
Whether it is winter heating or daily water use, temperature control accuracy is crucial. A good fully premixed condensing wall mounted boiler can achieve precise temperature control of ± 0.5 ℃, avoiding problems such as sudden changes in temperature during heating and large fluctuations in water temperature when using water. For example, in winter, different spaces such as living rooms and bedrooms have different temperature requirements. Products with zone temperature control function can independently adjust the temperature of different rooms by connecting multiple thermostats; In the water usage scenario, precise water temperature control can ensure stable water flow temperature during washing and vegetable washing, improving user comfort.
2、 Pay attention to energy consumption and energy-saving design, and reduce long-term usage costs
Although the fully premixed condensing wall mounted boiler itself is more energy-efficient than traditional wall mounted boilers, there are significant differences in energy-saving design among different products, which directly affects the subsequent cost of use. When purchasing, attention should be paid to the following two points:
1. Thermal efficiency stability: avoid efficiency decline after long-term use
Some fully premixed condensing wall mounted boilers have high thermal efficiency during initial use, but as the usage time increases, the efficiency will significantly decrease due to internal component wear or scaling issues. When making a purchase, you can check whether the product is made of corrosion-resistant heat exchanger materials (such as stainless steel, oxygen free copper, etc.), which can reduce scale adhesion, extend the service life of the heat exchanger, and ensure long-term stable thermal efficiency. Meanwhile, products with automatic cleaning function can regularly clean internal impurities, further maintaining efficient operation.
2. Intelligent energy-saving function: adapted to household usage habits
Nowadays, many fully premixed condensing wall mounted boilers are equipped with intelligent energy-saving functions, such as timed power on/off, timed temperature control, and remote control through mobile apps. For example, office workers can set the heating temperature to be lowered during weekdays and automatically heated up one hour before returning home, which not only does not affect the user experience but also reduces energy consumption; Mobile remote control allows users to adjust device status through their phones at any time when they forget to turn off their phones, avoiding unnecessary energy waste.
3、 Inspect installation and after-sales service to ensure long-term stable use
The installation professionalism and after-sales guarantee of fully premixed condensing wall mounted boilers are directly related to the service life and safety of the equipment. These two links are often overlooked, but they are crucial:
1. Installation team: Choose a professional service team
The installation of fully premixed condensing wall mounted boilers involves multiple stages such as pipeline layout, smoke pipe installation, and water pressure commissioning. Improper installation not only affects the effectiveness of use, but may also pose safety hazards. When making a purchase, it is necessary to confirm whether the brand provides an officially certified installation team. Professional installers will develop a reasonable installation plan based on factors such as the house layout, orientation, and insulation situation. For example, smoke pipes need to be tilted at the specified angle to avoid rainwater backflow; Pipeline connections should be properly sealed to prevent water or gas leakage.
2. After sales guarantee: Clearly define the scope of warranty and response speed
Equipment malfunctions are inevitable during use, and comprehensive after-sales support can make users more worry free. When making a purchase, it is important to inquire about the warranty period of the product. Typically, the warranty period for the entire pre mixed condensing wall mounted boiler is 2-5 years, while the warranty period for core components such as heat exchangers, fans, water pumps, etc. may be longer. At the same time, understanding the response speed of the after-sales team, such as whether 24-hour hotline service is provided and how long it takes to arrange for maintenance personnel to come to the door after a fault is reported, can reduce the impact on daily life when equipment problems occur.
4、 Match product adaptability based on actual family needs
The suitable fully premixed condensing wall mounted boilers vary depending on the size, water demand, and housing structure of different households. Blindly pursuing high power or high configuration may actually result in waste:
1. Floor Area: Accurately match power size
The power of the fully premixed condensing wall mounted boiler needs to be adapted to the floor area of the house. A low power will result in insufficient heating effect, while a high power will increase energy consumption. Generally speaking, households with a building area of 80-120 square meters can choose products with a power of 24-28 kW; Families with an area of 120-160 square meters can consider products with a capacity of 28-32 kW; If the house area exceeds 160 square meters or there are multiple bathrooms using water at the same time, it is recommended to choose high-power products with a capacity of 32kW or more to ensure that heating and water needs are met simultaneously.
2. Water quality adaptation: avoid scale affecting equipment life
The hardness of water quality varies greatly in different regions. Areas with harder water quality are prone to scale formation, which can adhere to the surface of heat exchangers and affect thermal efficiency, even leading to equipment failure. When making a purchase, you can pay attention to whether the product has water softening function, or consult the merchant if they provide a matching water purifier to reduce scale formation from the source. In addition, if the house is renovated from an old house, it is necessary to check in advance whether the original pipelines are compatible with the fully premixed condensing wall mounted boiler, and upgrade the pipelines if necessary to ensure the normal operation of the equipment.
Choosing a fully premixed condensing wall mounted boiler is not necessarily better if it is more expensive, but rather based on one's own heating needs, usage habits, and household conditions, taking into account the four key points of core performance, energy consumption design, installation and after-sales service, and adaptability. Only by grasping these key factors can we select products that meet our needs and are economically practical, making winter heating more comfortable and worry free, and achieving higher cost-effectiveness even with long-term use.
