Boiler, tank, buffer storage
The hot water supply is key to a comfortable home. The boiler, tank and buffer storage all offer an ideal solution for storing hot water, but they all have their own advantages and disadvantages. In our online store you will find a wide selection of well-priced boilers, indirect storage tanks and buffer tanks, so that you can find the type that best suits your needs and your heating system.
It is not enough to produce hot water, you also have to store it.< br />Bargain boiler, use of indirect storage tanks for storing hot water, bath water, without heat exchanger, with 1 or 2 heat exchangers.
Buffer tank, tank for storing large amounts of hot water, for auxiliary heating without a heat exchanger, with 1 or 2 heat exchangers, domestic hot water storage (tank in the tank) or fresh water module, i.e. a built-in stainless heat exchanger in addition with ribbed pipe.

Boiler, tank, buffer storage: hot water storage simply and efficiently
Discover our affordable buffers and indirect tanks, which are ideal for storing hot water and bath water in a convenient and efficient way. The boilers and storage tanks are made of high-quality materials and provide the possibility to install one or even two heat exchangers.
Why is hot water storage important?
- The demand for hot water fluctuates during the day, so it is important to have a reserve from which we can take the required amount of hot water at any time.
- Hot water storage can result in energy savings, as the boiler does not have to run continuously to maintain the temperature.
- The stored hot water ensures comfortable showering, bathing and washing dishes.
Indirect storage with heat exchanger:
- The indirect storage is a thermally insulated tank in which the water is not heated directly, but through a heat exchanger.
- The water circulating in the heat exchanger absorbs the heat of the heating system, so the boiler does not need to consume extra energy to heat the water.
- HMV storage = Domestic Hot Water storage or boiler
Buffer storage:
- The buffer storage is a large, thermally insulated container that stores the thermal energy of the heating system.
- The stored thermal energy can be used for heating, domestic hot water production, or even swimming pool heating.
- Enables the heating system to work more efficiently and can result in energy savings.
It is not enough to produce heat in a solar collector, it is also necessary to store the heat. An indirect storage is required for heating and storing water for use (bath water), since we do not circulate tap water in the collector, but antifreeze or, in the case of Gravikol, alcohol.
The indirect storage means that inside the tank there is a long tube spiral, i.e. a heat exchanger, in which the liquid heated by the solar collector circulates. This long tube spiral then heats up the cold water in our boiler.
You can also buy a boiler equipped with 2 heat exchangers, the lower one is the heat exchanger of the solar system, and the upper one it is heated by a boiler, cirque or open-water fireplace.
Some tanks do not have a tube spiral, but so-called mantle heating, i.e. a tank within a tank, the outer thin the solar hot liquid flows in a layer, heating the inner tank. This is usually a feature of collectors that can be installed horizontally.
An electric heating insert can be ordered for the majority of domestic hot water storage tanks (DHW), and in some it is standard equipment.
The buffer tank is distinguished from the indirect tank by the fact that it has a simple, non-surface-treated steel tank, which only needs to be filled with water once. Nevertheless, it does not rust if it is continuously filled with water.
A boiler, firebox, fireplace or heat pump is connected directly to it and the hot water obtained from this flows through the radiator and underfloor heating.
If we only heat it traditionally and this water also circulates in the heating system, then there is no need for a heat exchanger. However, if I want to connect a solar collector to it, then I need a pipe snake, in which case the buffer storage already has 1 heat exchanger.
Why is it necessary?
Antifreeze circulates in the solar collector system, and this must not mix with the water of the heating circuit, since it contains tap water, antifreeze is unnecessary. The solar collector heat exchanger is at the bottom of the buffer tank, since the cold water is stratified at the bottom of the tank, and the heated water will flow to the top. This heat exchanger is at the top, since the warm water collects in the upper part of the buffer tank, which then heats this upper
pipe snake.
