Gas boilers - an effective source of heat for every home

Gas boilers are one of the most popular heating solutions . They are efficient and economical. They provide thermal comfort all year round. At Onninen we offer a wide selection of gas boilers. Our offer includes devices from leading manufacturers. We supply condensing and conventional boilers. We also have sets with boilers and accessories.

Our customers often ask about the differences between boiler types.   Condensing boilers are currently the most modern solution . They use heat from exhaust gases. Thanks to this, they achieve efficiency even above 100%. They are more economical than traditional models. They are especially useful in new buildings. Conventional boilers, on the other hand, are a simpler and cheaper option. They are useful in older buildings.

Gas boilers - a wide range of leading brands

In the Onninen assortment you will find boilers from renowned manufacturers. We offer devices from the De Dietrich, Immergas, Termet, Bosch and Wolf brands. Each of them has its strengths. De Dietrich is famous for innovative solutions. Immergas is synonymous with reliability. Termet offers a good price-quality ratio. Bosch is German precision. Wolf stands out for its energy efficiency.

Our experience shows that customers appreciate the diversity of the offer . Thanks to this, they can choose a boiler that is ideally suited to their needs. Some look for simple and economical solutions. Others focus on advanced functions and design. At Onninen, everyone will find the right model. We provide professional advice when choosing.

Gas boilers - how to choose the right model?

Choosing the right boiler is a key issue. It affects comfort and heating costs.   When choosing, there are several important factors to consider . The most important are:

  • Surface area and volume of heated space
  • Demand for domestic hot water
  • Type of heating installation
  • Available space for boiler installation
  • User Control Preferences

In everyday practice, we encounter various situations. For a small apartment, a compact dual-function boiler is enough. A large single-family house requires a more powerful device. Sometimes the best solution is a boiler with a domestic hot water tank. It all depends on individual conditions.

Onninen recommends considering condensing boilers . They are more expensive to buy. However, in the long run, they bring savings. They use less gas. They are also more environmentally friendly. This is important in the context of rising energy prices. It is worth investing in an effective solution.

We recently completed a project for a large housing estate. The developer opted for De Dietrich condensing boilers. The choice fell on the MCR3 model in the dual-function version. The devices proved to be excellent. Residents praise the low gas bills. They also appreciate the quiet operation of the boilers.

In the case of modernization of older buildings, the situation is more complex. It is often necessary to adapt the installation. Our specialists advise on optimal solutions. Sometimes it is better to choose a conventional boiler. Other times it is worth investing in the modification of the heating system. It all depends on the specific case.

Gas boilers - accessories and control systems

Modern boilers are advanced devices with a wide range of functions . Much depends on the selection of appropriate accessories. At Onninen we offer comprehensive solutions. Our range includes:

  • Room and weather regulators
  • Chimney kits
  • Hot water exchangers and tanks
  • Remote control systems
  • Internet modules

Special attention should be paid to controllers. Modern controllers significantly increase the comfort of use. They allow precise temperature management. They allow programming of the boiler's operation. Some models offer control via the Internet. This is a convenient solution for people who travel often.

Our observations show that customers are increasingly asking about smart systems. They want to be able to control their heating via smartphone. Such solutions are offered by Bosch and Wolf, among others. Their controllers work with popular voice assistants. This allows for even more convenient management of home heating.

At Onninen, we focus on comprehensive service . We offer not only boilers, but also complete sets. They include a boiler, controller and hydraulic equipment. This is a convenient solution for installers. All components are selected and ready for installation. This saves time and minimizes the risk of errors.

Many customers ask us about heat exchangers. This is an important element of the heating system. A good exchanger ensures efficient preparation of hot water. We offer plate and tube models. Each type has its advantages. We will advise which solution will be optimal in a specific case.

Onninen provides full technical support. Our specialists are available to help at every stage. We advise on the selection of a boiler and accessories. We help in the event of problems with installation. We organize training for installers. Thanks to this, they have up-to-date knowledge of the latest solutions.

Gas boilers are our specialty . We have many years of experience in this industry. We know the specifics of the market and the needs of our customers. We focus on proven solutions and innovations. Thanks to this, we can offer optimal products for each investment. We invite you to contact us and take advantage of our knowledge.
