Main Frequently asked questions How to connect a buffer tank to a solid fuel boiler

Схема підключення буферної ємності до твердопаливного котла

Heating is always a hot topic, given the rise in tariffs. And recently, more and more often consumers of solid fuel equipment are encouraged to install a buffer tank in the system. This is really a huge advantage in saving money and time for the maintenance of solid fuel equipment. It is ideal to connect the buffer tank to the boiler at the same time when installing a solid fuel boiler.

A solid fuel boiler and a heat accumulator in tandem have their advantages in heating. You can have the simplest solid fuel boiler, without modern modifications, but with the use of a tank in the system, its operation will give a head start to any long-burning boiler, or at least will not be inferior in the comfort of maintenance and will correctly consume heat, reduce the number of approaches to the furnace chamber and fuel costs.

The main reasons for connecting a buffer tank:

    The need to save costs;
Increase heat transfer;. And here the question often arises, "How to connect a heat accumulator to a boiler?".
In order for the installation of the buffer tank to be safe and the heat accumulator to serve effectively, you need to know some of the nuances of the connection. What we will talk about next.

How to connect a buffer tank?

First of all, it is worth considering that the buffer tank is quite large and it is ideal to prepare the room for it at the design stage of the building. It is also better to install a solid fuel boiler with a buffer tank immediately.But this is not always the case. Based on this, manufacturers began to produce them round and flat, which makes it easier to place them in a finished building, where there may not be enough space.

To connect a heat accumulator in the heating system, it is important to correctly calculate the capacity of the tank. And therefore, there is a special calculation formula.

Q = m * cp * (T2-T1), in which

    m is the mass of the coolant used in the tank;cp is the specific heat capacity of the liquid accumulated in the heat accumulator;T2 and T1 - the average temperature of the coolant in the tank before and after heating.
There is also a calculation of the buffer capacity. So it is customary to consider the volume in the ratio of 30-50 liters of capacity per 1 kW of boiler.

What is important to know during installation:

    The vertical buffer tank is allowed to be connected only in rooms with a positive temperature.
  1. Installation and commissioning must be performed by a specialized company.
  2. Water should be used as a coolant.
  3. After the first start-up, check the connection points for leakage. The heat accumulator must be grounded in accordance with the requirements of NPATO 40.1-1.21-98 & laquo;Rules for the safe operation of electrical consumer installations& raquo;. Grounding is carried out through a special bolt M8x25, which is located at the bottom of the heat accumulator.
  4. It is also best to insulate the buffer tank. This will allow better heat accumulation and prevent burns.
The sequence of installation of tank insulation:

The removable insulation is exposed to ambient temperatures. When installing in a cold room, it is necessary to heat the insulation to 20-25 ° C. Here are some schemes for connecting a heat accumulator to a solid fuel boiler!

I hope that we have answered the question "How to connect a heat accumulator?" and that it was useful to you! Not always the easiest way is the most effective. You need to look wider and make economic calculations.

Don't forget about safety measures and the fact that a good manufacturer always describes important information in the product manual. It will also help you to set up the equipment correctly. Therefore, the information from the manufacturer should not be ignored! And then the connection will be easier!
