The boiler is responsible for heating and hot water in most houses in Korea. The average service life of a boiler is not precisely defined, but if it has been used for more than 10 years depending on the method of use, it is considered time to replace it. As a result, in residential boilers that have been used for more than 10 years, major parts such as the control box, fan motor (blower), thermostat, and heat exchanger, which are the main board of the boiler, wear out one by one, causing frequent A/S of the parts. do.
Boiler Replacement Costs and Types of Gas Boilers for Homes 보일러 교체비용
Let’s take a look at a typical residential gas boiler. 좋은뉴스
Recently, boilers mainly used in houses such as apartments and villas are often gas boilers using city gas, and oil boilers are often used when living in the outskirts of the city. In the case of gas boilers, condensing boilers and general boilers are sold separately, and the difference between condensing boilers and general boilers is due to the number of heat exchangers. Conventional boilers have one heat exchanger, whereas condensing boilers have two heat exchangers.
The term condensing in boilers comes from the dictionary definition of ‘compress’, which means that the heat that escapes is recirculated and used once, reducing energy use and increasing thermal efficiency. As much as it can be reused compared to the used fuel, the thermal efficiency is good compared to the used fuel, so the fuel cost can be reduced to that extent. However, condensing boilers are sold at a higher price than regular boilers.
My house is also using a condensing gas boiler, and although it is not the effect of saving energy up to 28% that the boiler company says, I personally feel that city gas fuel costs are reduced by 10-15% compared to the previous general gas boiler. Could. However, it should be taken into account that the initial purchase cost is 30% to 50% higher than that of ordinary boilers.
Major home boiler companies in Korea are Rinnai Korea, Kiturami Boiler, Kyungdong Navien, Daesung Celtic, etc. The prices of home boilers for each type generally sold are similar, but the boiler companies mentioned above are relatively expensive in order. . Rinnai Korea’s boiler is sold at the highest price among similar types of boiler models, and Daesung Celtic’s home boiler is sold at a relatively low price.
Area of the house according to the boiler capacity
In the case of boilers, models and prices differ depending on the boiler capacity. In general, the boiler capacity is classified into 13K, 16K, 20K, 25K, 30K, etc., and the capacity is expressed as the amount of hot water produced by burning fuel (heating). . In general, capacity is also related to house equilibrium, and 13K means that it has a heating efficiency of 13,000 kcal/hour. In other words, it means that 13,000 kcal of heat can be generated in 1 hour, and in general, it means the heating output that can raise 13,000 L of water by 1 ℃.
The area of a house according to the boiler capacity has relative variables depending on the amount of hot water used by household, but in general, apartments and villas of around 20 pyeong have a capacity of 13K, apartments of 25 pyeong have a capacity of 16K, apartments of 32 pyeong have a capacity of 20K, and apartments of 40 pyeong have a capacity of 25K. Choose your boiler. Of course, the large capacity of the boiler compared to the area of the house means that there is no big problem even if there is a lot of temporary hot water usage. However, on the contrary, it also means that a lot of fuel is consumed, so the increase in fuel cost is inevitable.
Boiler replacement cost, cheap replacement
Boiler replacement costs vary greatly depending on the region and the replacement company. In general, when a boiler is replaced using a joint purchase of an apartment or a joint purchase of a company, it is about 450,000 to 500,000 won (cash price) based on 16K. Since an additional cost of 30,000 to 50,000 won is incurred for each boiler capacity stage, 13K costs 400,000 to 450,000 won and 20K costs 500,000 to 550,000 won. Of course, as mentioned above, the boiler replacement cost is a concept that includes the replacement engineer’s labor cost in addition to the boiler price.
Boiler replacement costs according to boiler capacity average between 30,000 and 50,000 won, and depending on the boiler manufacturer, the average difference between 20,000 and 30,000 won also occurs. For example, if Rinnai Korea’s 16K product is 550,000 won, cricket is 530,000 won, Kyungdong Navien is 520,000~530,000 won, and Daesung Celtic is 480,000~490,000 won. Here, the approximate calculation is correct considering that the difference between the large and small boiler capacity is generally about 30,000 won. You can choose the brand and capacity according to your personal situation, and in my case, I tend to use the Kyungdong Navien series, which has good cost-effectiveness.
If so, if the existing boiler is replaced with a 13K Kyungdong gas boiler in an apartment or villa of around 20 pyeong (16-21 pyeong), the average cost is about 400,000 to 450,000 won depending on the region and company. Occurs. Of course, it is based on cash payment, and in most cases, 10% VAT must be paid when a cash receipt is issued.
Boiler replacement cost should be documented when calculating transfer tax with proof
Boiler replacement costs are included in house repair costs for capital gains tax reduction if capital gains tax is incurred when selling a house. Therefore, it is a good idea to keep receipts for boiler replacement costs even in order to reduce transfer tax costs that may occur in the future. Therefore, if possible, it is recommended to issue a credit card or cash receipt and use the receipt as proof when calculating the transfer tax cost.
Online shopping mall boiler sales advertisement (basic installation fee of KRW 150,000)
How to reduce boiler replacement costs
1. Utilize a joint purchase of an apartment or a trading company for a management office
The first way to replace a boiler at low cost is to use a joint purchase of an apartment boiler. In general, large-scale apartments have a boiler group purchase replacement advertisement leaflet attached, or through an apartment management office or tenant association, you can find a company that replaces them at a lower price than when you replace them individually. In this case, the cost of replacing 13K and 16K general boilers is usually between 400,000 and 500,000 won. Depending on the boiler brand and capacity upgrade, an additional cost of around W30,000 will be incurred.
2. Additional payment of basic installation fee after purchasing online shopping mall
The second method is to purchase a boiler through an online shopping mall. In this case, you should not blindly select a boiler just because it is cheap. If you purchase a boiler online, you will usually receive a separate installation fee, and in this case, even if the boiler is cheap, there are many cases where additional installation and option costs are requested, so in some cases, the purchase is more expensive than a joint purchase of a boiler. Therefore, when purchasing a 13K and 16K general-type boiler online, the boiler purchase cost is set at an average of less than 300,000 won (around 250,000 ~ 300,000 won) by using online shopping mall coupons for the regular price of 300,000 won, and the installation cost is at least It is good to decide on a purchase within the basic installation cost range of 120,000 won to 150,000 won.
In case of maximizing the use of the shopping mall itself, in the case of 13K~16K boilers, replacement can be done at around KRW 350,000. When purchasing online shopping malls, there is an advantage in that you do not have to pay additional VAT for cash receipts or credit card use, and you can provide proof of necessary expenses for transfer tax by only paying an additional 10% VAT only for basic installation costs.
