Tanks for oil boilers

Oil boiler tanks - the key to efficient heating

At Onninen we specialise in supplying the highest quality tanks for oil boilers.   Our products guarantee safe and efficient storage of heating oil. We offer a wide range of solutions tailored to the various needs of our customers.

Oil boiler tanks are a key element of the heating system. They provide constant access to fuel and maintain its appropriate quality. In our offer you will find both single-wall and double-wall tanks.

Types of oil boiler tanks available at Onninen

Our range includes two main types of tanks:

• Single-wall tanks - an economical solution for smaller installations
• Double-walled tanks - providing additional safety and environmental protection

Single-wall tanks are a popular solution in single-family homes.   They are lighter and cheaper than their double-walled counterparts. However, they require an additional catch basin. Double-walled tanks have a double wall. This increases the safety of storing heating oil.

In everyday practice, we observe a growing interest in double-walled tanks. Customers appreciate their increased safety and compliance with environmental protection standards. These tanks are particularly recommended for installation in basements or garages.

Accessories for heating oil tanks

Onninen's comprehensive offer also includes the necessary accessories:

• Fuel level indicators - allow for constant monitoring of the oil level
• Basic connections - necessary to connect the tank to the installation
• Series connections - allow you to connect several tanks

Fuel level gauges are a key element of every oil installation.   They allow you to constantly monitor the oil level in the tank. This way, you can avoid situations where there is a sudden lack of fuel. Our offer includes both simple mechanical indicators and advanced electronic systems.

Basic and serial connections are elements often omitted when planning the installation. However, they are essential for the proper functioning of the system. Our connections are characterized by high quality of workmanship and durability. They ensure a tight and safe connection of the tank to the heating installation.

Selecting the right tank for an oil boiler

Choosing the right tank is a key decision when designing a heating system. At Onninen, we provide expert advice in this area. When choosing a tank, several important factors should be considered:

The tank capacity should be adapted to the fuel demand.   A tank that is too small requires more frequent refilling. A tank that is too large generates unnecessary costs. Optimal capacity selection ensures comfort of use and economical operation.

The location of the tank is very important for choosing its type. For tanks placed outside, we recommend double-walled models. They provide better insulation and protection from weather conditions. Internal tanks can be single-walled, but require an additional catch basin.

It is also worth paying attention to the material the tank is made of. Our offer includes steel and plastic tanks. Each solution has its advantages. Steel tanks are more resistant to mechanical damage. Plastic ones are lighter and resistant to corrosion.

Our experience shows that customers often underestimate the importance of accessories. A properly selected fuel gauge or connection system can significantly increase the comfort of use. That is why we always recommend a comprehensive approach to the subject.

At Onninen we offer tanks for oil boilers from renowned manufacturers.   Among them are our own brands: Onnline and FXA. These products combine high quality with an attractive price. They are the result of our many years of experience in the industry.

We recently completed a project for a large office complex. The client needed an efficient and safe heating oil storage system. We used a set of double-walled tanks with a total capacity of 20,000 liters. The system was equipped with advanced fuel level indicators and automatic refilling.

When modernizing older heating systems, we often come across questions about the possibility of replacing the tank. This is a great opportunity to improve the efficiency of the entire system. Replacing an old, single-wall tank with a modern double-wall model brings tangible benefits.

Oil boiler tanks are not only an element of the heating system.   It is also an investment in safety and environmental protection. Modern tanks are equipped with systems that prevent leaks. This minimizes the risk of soil and groundwater contamination.

At Onninen, we regularly train our staff in the latest oil tank technologies. This allows us to provide expert advice at every stage of the project. From selecting the right tank, through its installation, to subsequent operation.

Many customers ask us about the possibility of connecting tanks into batteries. This is an excellent solution in the case of a larger demand for fuel. Our series connections allow for the safe and efficient connection of several tanks into one system.

Oil boiler tanks are products with a long service life.   With proper maintenance, they can serve for many years. That is why it is worth investing in high-quality solutions. At Onninen, we offer products that meet the highest quality and safety standards.

When reorganizing the heating space, we most often encounter the need to optimize space. Our tanks are available in various shapes and sizes. This allows for efficient use of available space without compromising capacity.

Onninen recommends regular inspections of oil boiler tanks. This allows for early detection of potential problems and extends the service life of the installation. Our specialists can perform a comprehensive inspection and advise on maintenance.
