Dual-function condensing gas boilers - an effective solution for your home

Combination condensing gas boilers are modern heating devices.   They combine the functions of heating rooms and preparing domestic hot water . At Onninen, we offer a wide selection of these boilers. Models from leading manufacturers are available. Among them are Immergas, Termet, De Dietrich, Ferroli and Beretta. Each of these brands has unique features and advantages. This allows you to choose a boiler for the individual needs of the customer.

Dual-function condensing boilers are distinguished by their high efficiency. They use the heat of condensation of water vapor from exhaust gases. As a result, they use less gas than traditional boilers.   In practice, this translates into lower heating bills . This is especially important with rising energy prices. Many people ask us about saving options. Condensing boilers are a great solution here.

Why is it worth choosing dual-function condensing gas boilers?

The main advantages of dual-function condensing gas boilers are:

  • High energy efficiency - up to 109%
  • Lower gas consumption and lower bills
  • Compact dimensions - space saving
  • Quiet operation - comfort of use
  • Environmentally friendly - lower exhaust emissions

In everyday practice, we see a growing interest in these boilers. Customers appreciate their versatility and cost-effectiveness.   Dual-function boilers work well in both small apartments and large houses . They eliminate the need to install a separate boiler. This saves space and simplifies installation.

How to choose the right dual-function condensing gas boiler?

Choosing the right boiler is a key issue. It affects comfort and operating costs. Several factors should be taken into account when choosing. The most important are the heated area and the demand for hot water. The ability to adjust the boiler power is also important. This allows you to adjust the device's operation to current needs.

At Onninen we often advise on the selection of boilers. Our experience shows that it is worth paying attention to:

  • Boiler power - adjusted to the size of the house
  • Hot water efficiency - depending on the number of household members
  • Device efficiency - the higher, the lower the costs
  • Noise level - important when installing in residential premises
  • Control options - e.g. via the Internet or mobile application

Modern gas condensing dual-function boilers offer advanced functions . Many models have power modulation. They adjust their operation to current demand. Some boilers have built-in hot water tanks. They provide higher comfort of use.

When choosing a boiler, it is also worth thinking about the future. Hybrid systems are becoming increasingly popular. They combine a gas boiler with a heat pump or solar panels. Such solutions allow for even further reduction of heating costs.

Installation and operation of dual-function condensing gas boilers

Correct installation of the boiler is the basis for its efficient operation. At Onninen we recommend using the services of certified installers. This ensures safety and warranty.   The right place to install the boiler is also important . It should be dry and well ventilated. The boiler must also have access to a chimney or flue pipe.

The operation of a gas condensing dual-function boiler is simple. However, it requires regular inspections. It is recommended to perform them once a year. The inspection includes cleaning and adjustment of the boiler. This allows to maintain high efficiency of the device. It also reduces the risk of failure.

In everyday practice, we come across questions about operating costs. Condensing boilers are economical to use. They use less gas than traditional models. However, it is worth remembering a few rules:

  • Regularly check the pressure in the installation
  • Bleeding radiators before the heating season
  • Setting the optimal room temperature
  • Using Thermostats and Programmers

Proper boiler operation translates into its long service life . It also has a positive effect on the efficiency of the entire heating system. At Onninen, we offer not only boilers, but also accessories for their operation. These include filters, dirt separators and water treatment sets.

We recently completed a project for a large housing estate. Dual-function condensing gas boilers were used there. The effects were impressive. Residents noted significant savings on bills. The comfort of using hot water also improved.

Condensing gas boilers with two functions are the future of home heating. They combine efficiency, economy and ecology. At Onninen, we are convinced of their advantages. That is why we are constantly expanding our offer in this area. We invite you to contact our consultants. They will help you choose the right boiler for your needs.
