Common problems in old houses: lack of pipe spacing, limited wall structure

Every time you step into an old house that bears the marks of time, you will always feel a unique nostalgic atmosphere, but behind this beauty, there are often many headaches hidden in the kitchen. The most common problem in older buildings is that the installation needs of modern kitchen appliances are not taken into account when designing, especially the pipe configuration of the range hood. Many traditional apartments have tight pipe spacing in the kitchen and limited wall structure, which are important factors affecting the smoke exhaust effect. Imagine installing your newly purchased range hood with high expectations, only to realize that the exhaust pipe needs to bypass beams, avoid water pipes, or pass through a tight mezzanine space.抽油煙機推薦

In the process of renovating old houses, we often encounter the dilemma that the structure of the walls cannot be changed at will, especially the load-bearing wall parts cannot be easily destroyed. At this time, professional evaluation is required to find the best pipeline path. Some older homes have kitchens inside the building, far from the exterior walls, which means that the smoke pipes need to travel longer distances. Some apartments have the problem of sharing pipes, and if neighbors also use the same pipes, there may be a situation where the smoke exhaust interferes with each other. These are the key points that must be prioritized when renovating an old home, which is why experts always emphasize the importance of planning ahead.

There are three key points in pipeline design: shortest distance, minimum elbow, and appropriate pipe diameter

When it comes to getting the best performance out of your range hood, tube design is the key to success or failure. After years of practical experience, we have summarized the three most important design principles: minimum distance, minimum elbow, and appropriate pipe diameter. Firstly, the length of the smoke exhaust pipe directly affects the smoke exhaust efficiency, and with each meter of length, the wind pressure decreases accordingly. Ideally, the total length of the exhaust pipe from the exhaust hood to the outdoor exhaust port should not exceed 3 meters.

The number of elbows is an invisible killer that affects the smoothness of the smoke exhaust. Each 90-degree elbow is equivalent to an increase in the length of the pipe by 1-2 meters, which significantly increases wind resistance. If you have to turn, it is recommended to use a 45-degree elbow instead of a 90-degree elbow to effectively reduce wind resistance. The choice of pipe diameter should match the size of the exhaust port of the range hood, with common diameters being 15 cm or 18 cm. The larger the diameter of the pipe, the better, but it should be noted that if the diameter of the pipe is too large, the wind speed will decrease, which will affect the smoke exhaust effect. In this list, special attention is paid to the compatibility of pipe diameters in each model to ensure that it can be adapted to different installation conditions in older houses.

Special solution: booster fan, dual motor system

If it is very difficult to change the state of the pipeline in an old house, then special technical solutions are needed to break through the restrictions. Booster fans are one effective solution because they are like adding a booster to the smoke exhaust pipeline to maintain sufficient air pressure over long distances. It is particularly suitable for situations where the kitchen is located in an apartment and the smoke exhaust pipe needs to be bypassed over long distances, such as when it needs to be discharged from the living room or balcony to the outside. When installing a booster fan, pay attention to the choice of a location, usually in the middle of the pipeline, to maximize the boost effect.

Another option worth considering is a range hood with a dual motor system. Traditional single-motor designs often seem inadequate in the face of complex pipeline conditions in older homes. The dual-motor system provides more powerful and stable suction power and maintains excellent smoke extraction performance even if the pipeline is slightly imperfect. In this round, we have selected several dual-motor models designed for harsh environments, but these usually have intelligent air pressure adjustment function, which can automatically adjust the output power according to the actual smoke exhaust resistance, which is both energy-saving and efficient. For residents living on high-rise floors, it is especially important to choose a model with a check valve design that can effectively prevent strong wind backflow, as the issue of wind pressure balance also needs to be considered.抽油煙機推薦

Ability to communicate with designers: clearly state the requirements for use

In the process of renovating an old house, the quality of communication with the designer directly affects the final result. When discussing kitchen design, many people often focus solely on visual elements such as cabinet style and countertop materials, neglecting the most important functional plan. To ensure a smooth range hood installation, you must first clearly communicate your cooking habits to the designer. If you frequently use Chinese fast stir-fry, you should emphasize the importance of smoke exhaust efficiency. If you frequently use large pans, consider the installation height and coverage of the range hood.

We recommend doing your homework before meeting with a designer to understand your specific needs. You can prepare a list of daily cooking frequency, frequently used cooking methods, and oil fumes that you are particularly concerned about. At the same time, it provides the exact dimensions of the kitchen, including details such as ceiling height, window position, and existing plumbing configurations. During the discussion, don't be afraid to ask professional questions, such as pipe diameter specifications, reserved maintenance space, etc. Professional designers will provide you with appropriate information based on your needs, and clearly show the pipeline direction and installation details in the blueprint. Don't forget to ask your designer to provide you with 3D simulation drawings to get a more intuitive understanding of what your finished product will look like and save you the hassle of making subsequent changes.

Suitable for renovating old houses

After detailed pipeline planning and demand analysis, the final step is to choose the right range hood. For the special conditions of the old house, the following types are especially recommended: Firstly, the diagonal deep coverage range hood can effectively expand the smoke collection range, which is especially suitable for families who frequently stir-fry. The high flexibility of installation and the relatively loose requirements of pipeline configuration make it the first choice for renovating old houses. The second is the hidden lifting range hood, which can perfectly blend into the style of the whole kitchen, can only be lowered when needed, does not take up much space, is beautiful and elegant, especially suitable for old apartments with limited space.

For older houses with low floor heights, we recommend an inverted T-shaped design that is thin and does not feel oppressive. If you have a really small kitchen space, you can consider a professional side suction type, which is installed directly on the wall and does not take up any vertical space. The installation of an old house often requires professional technical support, and choosing a brand with a complete service network can save you a lot of worries, so when it comes to choosing a brand, you need to pay special attention to after-sales service and warranty terms. Finally, no matter which type of range hood you choose, it is important to ensure that its airflow and air pressure meet your actual needs, and in general, it is recommended to choose a model with an airflow of at least 15 cubic meters per minute to effectively address the smoke exhaust problems that may exist in older homes.
