Vertical exchangers

Vertical exchangers - effective solutions for heating systems

Vertical exchangers are a key element of modern heating installations.   They ensure efficient heat exchange and storage of domestic hot water.   At Onninen we offer a wide selection of vertical heat exchangers from renowned brands. Our specialists will advise on the optimal selection of the device. We often come across questions about the differences between the types of heat exchangers. It is worth knowing that we distinguish single- and double-shell heat exchangers. The latter have an additional coil. This increases their versatility. It allows cooperation with various heat sources.

Types of vertical heat exchangers available in the Onninen offer

Our range includes various types of vertical exchangers:

• Single coil heat exchangers
• Bivalent heat exchangers (two coils)
• Heat pump exchangers
• Spiral exchangers
• Hot water tanks

We offer products from renowned brands such as Galmet, Kospel, Immergas and Biawar.   We especially recommend our own brand Onnline.   Its exchangers combine high quality with an attractive price. Our experience shows that they are highly appreciated by installers. They appreciate their reliability and ease of installation. Onnline exchangers work well in both single-family homes and larger facilities.

Criteria for selecting vertical exchangers

When selecting the right vertical exchanger, there are several key factors to consider:

• Tank capacity
• Heating power
• Type of heat source
• Number and type of coils
• Tank material
• Type of insulation

The proper selection of these parameters has a huge impact on the efficiency of the entire heating system.   At Onninen, we offer professional advice in this area. Our experts will help you choose the optimal exchanger for your specific needs. We take into account the specifics of the building and the preferences of the users. We often come across a situation where the customer plans to expand the system in the future. In such a case, we recommend bivalent exchangers. They enable easy integration of additional heat sources.

Practical applications of vertical exchangers

Vertical exchangers are widely used in various types of installations. In single-family houses, they are most often used to prepare domestic hot water. They then work with a gas boiler or heat pump. In larger facilities, such as hotels or sports facilities, cascade systems are used. They consist of several connected exchangers. This ensures a stable supply of hot water even with large, variable demand.

We recently completed a project for a large swimming pool complex. We used a system consisting of six Onnline vertical exchangers. Each had a capacity of 1,000 liters. This solution not only ensured efficient water heating, but also the flexibility of the system. This enabled the optimization of energy consumption depending on the current load of the facility.

In our daily practice we see a growing interest in heat exchangers for use with heat pumps.   These devices have a special coil design. It ensures optimal heat exchange at low supply temperatures. This is crucial for the efficiency of the entire system. Heat pump exchangers are often equipped with an additional electric heater. It is a safeguard in the event of very low outside temperatures.

It is also worth mentioning spiral exchangers. They are mainly used in solar installations. Their special design provides a large heat exchange surface. This translates into high efficiency with variable sunlight. At Onninen we offer spiral exchangers of various capacities. This allows you to choose the right device for both small home installations and larger systems.

We often come across questions about the durability of vertical exchangers. The material of the tank is crucial here. The most popular are enameled tanks. They provide good protection against corrosion at a moderate price. For more demanding applications, we recommend stainless steel exchangers. Although they are more expensive, they are characterized by exceptional durability.

Our experience shows that more and more customers pay attention to the insulation of heat exchangers.   This is understandable in the context of rising energy prices. At Onninen, we offer heat exchangers with high-quality polyurethane foam insulation. It ensures minimal heat loss. This translates into lower operating costs for the entire heating system.

In the case of modernization of existing installations, we often recommend hanging exchangers. They take up less space than free-standing models. This is especially important in smaller boiler rooms. Hanging exchangers are available in various capacities. This allows you to choose the right model for your specific needs.

Onninen, as a leader in the installation industry, constantly monitors the latest market trends. We notice a growing interest in intelligent energy management systems. That is why our offer includes heat exchangers adapted to integration with such systems. They enable remote monitoring and optimization of the entire heating installation.

We invite you to contact our specialists. They will help you choose the optimal vertical exchanger for your needs. We provide professional advice, fast order fulfillment and full technical support. With Onninen you gain not only a product, but a comprehensive solution for your heating system.
