There are a wide variety of wall mounted boiler products on the market, with various parameters and promotions that are dazzling. In fact, the key to choosing the right equipment lies in understanding several core questions: how much hot water does your home need? How about the insulation of the house? What are your daily usage habits? Follow this guide step by step analysis to ensure that you avoid detours.

Step 1: Understand the real needs of the family

There are several bathrooms in the observer's room. If there is only one bathroom and the area does not exceed 200 square meters, choosing a 24 kW unit is basically enough. But if there are two bathrooms or more than five people living in the house, especially those who like to take showers, it is recommended to have a model with at least 28 kilowatts, otherwise there may be an embarrassing situation of insufficient hot water.

The age of the house is also important. Newly built houses usually have insulation layers on their exterior walls, calculated at a standard of 100 watts per square meter; The insulation of the old house is much worse, and the power should be estimated at 120 watts per square meter. If you want to install a wall mounted boiler in an old house, it's best to first check if the exterior walls have insulation layers. If not, adding insulation layers can save a lot of gas costs.

Step 2: Calculate the long-term usage cost

Take a piece of paper and record the number of heating days, house area, and natural gas unit price for each year at home. For example, if you use 300 days a year for heating, a house of 100 square meters, and natural gas costs 3 yuan per cubic meter, the annual gas cost is approximately 900 yuan: 300 days x 100 square meters x 3 yuan/square meter ÷ 1000=900 yuan. At this point, it is necessary to compare the prices of conventional furnaces and condensing furnaces - if the condensing furnace is 3000 yuan more expensive and can be used for 10 years, the additional cost per year is equivalent to an extra 1 yuan per day, but the saved gas cost can make up for the difference in two years. Of course, the specific situation also depends on the local gas prices and the insulation of the houses.

Step 3: Installation details determine the experience

Installing a wall mounted boiler is not just about finding a spot to stick it on the wall. If the farthest bathroom in your home is more than 15 meters away from the wall mounted boiler, it is recommended to choose a model with zero cold water function, otherwise you will have to wait for half a minute every time the water faucet is turned on, which seriously affects your quality of life. If you want to install zero cold water, remember to plan the pipeline route in advance to avoid damaging the wall during later renovations.

The position of the smoke exhaust pipe needs to be carefully considered. The smoke pipe of a regular wall mounted boiler cannot exceed 7 meters in length (including bends), while the smoke pipe of a condensing boiler can be extended to about 13 meters due to the need to discharge hot water. When installing, be careful not to bend the smoke pipe too much, otherwise it will affect the combustion efficiency. In addition, the condensed water generated by the condenser must be discharged into the sewer, and it is necessary to confirm in advance that there is a drainage outlet near the installation location.

Step 4: Intelligent configuration enhances comfort

Nowadays, wall mounted boilers can be connected to mobile apps. In winter, you can turn on the heating before going home and warm up as soon as you enter. This remote control function, although not a necessity, can make life more convenient. If the home is equipped with underfloor heating, it is recommended to choose a model that can automatically adjust the water temperature, which can ensure comfort and save gas. However, it should be noted that wall mounted boilers without intelligent functions may be more prone to malfunctions. Remember to confirm the warranty policy for accessories before purchasing.

Step 5: Ensure good after-sales service

Buying a wall mounted boiler should not only be based on price, but also on after-sales service. First tier brands usually have a complete machine warranty of more than 5 years, and core components such as burners can be guaranteed for 10 years; Small brands may only have a warranty of 3 years, and repair parts are particularly expensive. It is recommended to choose brands that provide free on-site installation and regular maintenance services, which are worry free and cost-effective. Finally, a reminder that regular cleaning of scale can prolong the use of wall mounted boilers by 3-5 years, and this maintenance fee is definitely worth spending.

By following these principles, you will definitely find a good wall mounted boiler that is both warm and cost-effective. Remember, professional selection is not about who knows the parameters better, but about tailoring according to one's own actual situation
