Storage tanks, exchangers, buffers

Tanks, exchangers, buffers - key elements of efficient heating systems

In modern heating installations, tanks, exchangers and buffers play an extremely important role.   They ensure efficient storage and distribution of domestic hot water and support the operation of the entire system.   Our company offers a wide selection of these devices from renowned manufacturers.

In our assortment you will find products of brands such as Galmet, Kospel, Ferroli or Immergas. We especially recommend solutions of the Onnline brand, which is our own brand. Its products combine high quality with an attractive price.

Types of tanks and exchangers available in the offer

We offer a variety of types of devices tailored to individual customer needs:

• Single and dual function heat exchangers
• Hot water tanks with capacities from 100 to 500 liters
• Heat exchangers for use with heat pumps
• Heat buffers
• Enameled or stainless steel exchangers
• Standing and hanging devices

Our experience shows that it is crucial to properly select the capacity and type of device for a specific installation.   That is why we always advise clients individually, taking into account the specifics of their heating systems.

Criteria for selecting tanks, exchangers and buffers

When choosing the right device, there are several important factors to consider:

1. Demand for domestic hot water
2. Type of heat source (gas boiler, heat pump, solar installation)
3. Available installation space
4. Required energy efficiency class
5. Investment budget

We are often asked what tank capacity will be optimal.   In practice, tanks with a capacity of 200-300 liters work well for the average family.   However, for larger households or commercial premises it may be necessary to use units with a capacity of 500 litres or more.

It is worth paying attention to bivalent exchangers, which enable cooperation with two heat sources. This is particularly useful in hybrid installations, combining, for example, a gas boiler with solar collectors.

In our daily practice, we see a growing interest in heat pump systems. For such installations, we recommend special exchangers dedicated to cooperation with these devices. They ensure optimal performance and energy efficiency of the entire system.

Innovations and trends in tank and exchanger technology

The heating industry is constantly developing, and with it the devices available on the market are evolving.   Currently, we are observing a trend towards solutions with high energy efficiency, marked with class A or higher.   Manufacturers are using increasingly better insulating materials, which translates into minimizing heat loss.

Recently, in a project for a large housing estate, we used tanks with a built-in electric heater. This solution provides an additional source of heat during periods of peak demand or in the event of a failure of the main heating system.

Many customers ask us about the possibility of integrating tanks with building management systems. Some models offer such functionality, which allows for remote monitoring and control of the device. This is especially useful in commercial facilities or smart homes.

In the case of office reorganization, we most often encounter the need to use compact solutions. That is why our offer also includes small hanging exchangers, ideal for installation in tight technical rooms.

Our experience shows that investing in a high-quality tank or heat exchanger pays off relatively quickly thanks to savings on energy costs.   That is why we always encourage customers to choose devices with the highest efficiency class available, even if this involves a slightly higher initial cost.

Onninen especially recommends enameled steel exchangers with additional anti-corrosion protection in the form of a magnesium anode. This solution ensures long-term and failure-free operation of the device, which is confirmed by the opinions of our customers.

In the context of rising energy prices, tanks with a built-in spiral coil are becoming increasingly popular. They enable efficient use of heat from low-temperature sources, such as heat pumps or solar collectors.

When selecting devices, we always take into account the specifics of a given installation. For example, in the case of solar systems, the use of double-coil exchangers is crucial. The lower coil then cooperates with solar collectors, and the upper one with an additional heat source.

In facilities with a large but irregular demand for hot water, heat buffers are useful. They allow for the storage of surplus energy and its use during periods of increased consumption, which translates into higher efficiency of the entire system.

Regardless of the solution chosen, correct installation and regular maintenance of the device is crucial.   That is why, in addition to selling products, we also offer professional technical advice and service. Thanks to this, our customers can enjoy trouble-free operation of the installation for many years.

We invite you to contact our specialists who will help you choose the optimal solution tailored to the individual needs of each client. Together we will find the best device that will provide the comfort of hot water while optimizing operating costs.
