Buffer tanks serve as a reservoir for heating water, which is heated by a heat pump or other heat source. By accumulating energy in the form of hot water, the buffer guarantees a smooth and efficient supply of heat for heating the house or utility water.

Characteristics of the buffer with a coil
The coil, which is an integral part of many buffer tank models, acts as a heat exchanger, allowing for a smooth flow of heat from one medium to another. Heat buffers with a coil facilitate the integration of various heat sources, such as solar panels or a solid fuel boiler. This increases the flexibility of the heating system and the investor can use available energy sources more effectively.
However, buffers of this type have disadvantages. Their initial cost may be slightly higher. They also require more space in the boiler room. It is also worth remembering that a buffer with a coil is not useful in every installation. It works well in installations using different heating circuits or equipped with additional heat sources. In the case of energy-efficient houses with underfloor heating as the only heating system, a buffer is not necessary.
Characteristics of buffer without coil
Coilless buffers are ideal for installations with a single heating circuit, where the heat pump is the main source of heat for heating the house. They enable efficient storage of excess heat when the heat pump is operating at full capacity and the demand for heat is low. This allows for the optimization of the pump's operation, which results in energy savings and reduced operating costs.
Heat buffers without coils are particularly useful in houses with underfloor heating as the only heating system. They allow you to maintain a constant temperature of the heating water in the system, which ensures comfortable and even heating of the rooms.
Using buffers without coils, you can also use two electricity tariffs, which makes the savings on bills even greater. The buffer tank can also work with a photovoltaic installation, allowing you to store excess electricity in the form of hot water, which allows you to heat your home at night without having to use electricity supplied from the electricity network.
How to choose the right buffer?
The choice between a buffer with a coil and a variant without a coil should depend on the specifics of the specific heating installation. The former works best in systems equipped with different heating circuits with different heating water temperatures or different heat sources.
A buffer without a coil, on the other hand, is best suited for installations with a single heating circuit - especially where the heat pump is the main source of heat. Such a buffer has a purely accumulation function, allowing for the storage of excess heat and optimisation of the pump's operation. There is no need to transfer energy from one circuit to another.
Buffer tanks at the Onninen wholesaler
In the offer of the Onninen installation wholesaler you will find a wide selection of buffer tanks, among which you will surely find a model adapted to the specifics of a given device.
Roth Thermotank Quadroline TQ-T buffer tank
This is the world's first pressure-resistant buffer tank. The Roth Thermotank Quadroline TQ-T buffer tank is manufactured using composite technology (glass fiber reinforced plastic) with an aluminum anti-diffusion layer. The model is compatible with all types of heat sources, primarily heat pumps, gas and oil boilers, and solar installations.
Galmet SG buffer tank
Buffer tank GALMET SG(B)1000L designed for storing demineralized boiler water. Thanks to the coil, it can be supplied from several sources. Hard polyurethane foam or soft detachable polyurethane foam provide a very low heat transfer coefficient. The Galmet SG tank can operate at a maximum pressure of 0.3 MPa2.
De Dietrich BT300 buffer tank
The De Dietrich BT300 buffer tank is designed to operate at a maximum operating pressure of 0.3 MPa3. Made of the highest quality materials, it works well even in installations operating in the most difficult conditions.
A properly selected buffer will increase the efficiency of the entire heating system, contributing to energy savings, comfortable heating and environmental protection. It is worth consulting the decision with a professional installer or employees of our wholesaler.
