What is the Difference Between Condensing Boilers and Condensing Combi Boilers ?

Heating systems play a crucial role in ensuring the thermal comfort of residences, workplaces and complexes such as sites, hotels, hospitals, schools, plazas, constructions, shopping malls, swimming pools, gyms and sports halls where high-volume central heating is needed. Within the scope of that, heating systems differ according to the energy sources they use, the way they distribute the energy being produced and their technical working principles. Therefore, although the concepts of condensing combi boiler and condensing boiler often seem to be interchangeable in our daily life, these two types actually have slight differences. Both of them obtain the highest efficiency from fuel by using condensing technology; but they differ from each other according to their structures, capacities and usage areas. In this article, we will briefly discuss the differences between the condensing boiler and the condensing combi boiler. 

  

What is a Condensing Combi Boiler ? 


A condensing combi boiler is a device used in the heating system by recovering the heat and water vapor generated when burning gas. Condensing combi boilers provide condensation of water vapor by cooling the gas before entering the chimney. By means of that, the released heat is transferred to the heating system. Condensing combi boilers have a higher efficiency rate than conventional combi boilers. They also are eco-friendly solutions thanks to reducing CO2 emissions. Condensing combi boilers are generally preferred in residential buildings and meet both heating and hot water needs. Full condensing combi boilers save energy thanks to their high efficiency. However, the capacity of a combi boiler is usually limited to a certain capacity and it is usually designed to meet the needs of a single dwelling. 

  

What is a Condensing Boiler? 

A condensing boiler, like a condensing combi boiler, is a device used in the heating system by recovering the heat and water vapor produced when burning gas. However, condensing boilers have a larger capacity and longer life than condensing combi boilers.  Ecodense condensing boilers  are divided into three main categories: Wall Hung Type, Floor Type and Roof Top Series Condensing Boilers 

Wall-type condensing boilers are smaller in size and mounted on the wall. Floor-type condensing boilers are larger in size and are placed on the floor. On the other hand, Ecodense Roof Top series condensing boilers are designed for outdoor usage and roof applications; these condensing boilers provide heating solutions for large-scale buildings and facilities such as shopping malls, office and plaza buildings, health and accommodation facilities.  

  

Within the regard of that, condensing boilers are designed to high heat transfer at wider areas and are often used in commercial and industrial areas. The capacity of these systems has a wide range to heat spaces of various sizes, from residential dwellings to large commercial buildings and industrial facilities. For example, the 150 kW wall-type condensing boiler of Ecodense product range is ideal for heating very extensive spaces. Additionally, all Ecodense condensing boilers are suitable for cascade operations and usage. This feature enables even aging with sequential operation, which means that the workload between the boilers is shared, extending the service life of the products. Moreover, Ecodense condensing boilers meet energy requirements at high power levels with low fuel consumption. 


To sum up, the differences between condensing combi boiler and condensing boiler can be listed as follows: 

  

  • Condensing combi boilers are devices that can meet both heating and hot water needs. Condensing boilers, on the other hand, are devices that can only meet heating needs. It is also necessary to use a boiler or water heater to meet hot water needs. 

  • Condensing combi boilers are generally installed in decentralized systems. Therefore, heat generators are separately mounted for each apartment. Whereas condensing boilers are usually used in centralized systems, meaning that there is a single heat generator providing total heat for the whole building. 

  • Condensing combi boilers are smaller and wall-mounted. Condensing boilers are larger and are wall or floor mounted. 

  • Condensing combi boilers have a lower capacity and shorter lifetime. Condensing boilers have higher capacity and longer life. 

  • Condensing combi boilers are more affordable and easier to install than boilers. Condensing boilers require higher budgets and are more complex to install. 

Condensing Combi Boiler vs. Condensing Boiler, Which One Should I Prefer? 

Below are some situations to consider when choosing a condensing combi boiler or condensing boiler:  

  

The size of the area to be heated: It may make more sense to choose a condensing boiler for heating large areas. 

  

The need for hot water: If you need a lot of hot water or if you want hot water constantly, it may be more advantageous to choose a condensing combi boiler. 

  

Budget: If your budget is limited or you want to keep the investment costs low, it may be more economical to choose a condensing combi boiler. 


Efficiency rates: Efficiency rates are almost the same for condensing combi boilers and condensing boilers, but the thermal efficiency rate may be slightly higher for condensing boilers.  

  

In conclusion, the difference between a condensing combi boiler and a condensing boiler depends on the locations, capacities and needs & demands. Both heating equipment offer high energy efficiency using condensing technology, but their usages and capacities are peculiar. When choosing the best option, one should take into consideration the heating needs & demands, the characteristics of the existing system and the costs. As explained in our article, condensing combi boiler and boiler prices may vary depending on the capacity and different technical features of the model. Ecodense's full condensing combi boiler and condensing boiler models with innovative premix technology offer a high level of value and comfort of use in terms of energy efficiency.
