In most cases, any heating system has three main parts, among them are pipe lines, heating radiators and a boiler, which is replaced by heating appliances. But systems of the latest generation are quite often equipped with other useful devices, among them a heat accumulator can be distinguished. Making it yourself at home is quite simple. With this addition, you can accumulate excess energy generated in the boiler and wasted. In most cases, these options are a metal tank, which is equipped with several nozzles located above and below. Heat sources are connected to the latter, while consumers are connected to the latter. Inside is a liquid that the owners can use for their own purposes.
Manufacture manipulations can be quite simple, for this you need to prepare a certain set of tools and materials, as well as be patient.
Design features
If you decide to make a heat accumulator with your own hands, first you need to familiarize yourself with the features and principle of operation of this equipment. The operation is based on the significant heat capacity of water. The boiler pipeline is connected to the upper part of the tank, the last of which receives hot water with the highest possible temperature. A circulating pump should be located below, which is responsible for selecting cold water and forcing it through the heating system. The liquid then flows back into the boiler.
In the shortest possible time, the previously cooled liquid is replaced with a freshly heated one. After the boiler stops functioning, the water in the system lines begins to slowly cool down. In the process of circulation, it enters the tank, in which the extrusion of hot coolant into the pipes begins. This allows you to provide space heating for a certain period of time.
The need to manufacture a heat accumulator
If you decide to make a heat accumulator with your own hands, you should know what functions it performs. It is worth considering that modern heat storage devices are quite complex devices that perform many functions. They provide housing with hot water, allow you to increase the efficiency of home heating systems to the maximum possible, while reducing financial costs for fuel. Among other things, the device is able to stabilize the indoor temperature.
SWith the help of this equipment, it is possible to combine several heat sources, enclosing them in a single circuit. The reverse task can also be done. A do-it-yourself heat accumulator is quite simply made. It will store excess energy generated by the boiler.
Disadvantages of a heat accumulator
If you decide to make a heat accumulator for a boiler with your own hands, then you need to take into account that it has significant drawbacks, among them we can highlight the fact that the water resource will depend on the volume of the installed tank. Capacity is a very limited concept, which is why water tends to run out. In view of this, owners of private houses quite often stock up on an additional heating system. The first drawback gives rise to the second: it is expressed in the need for an impressive area, which is required by more resource-intensive installations. This may be a separate room, which looks like a boiler room. Not every home has the possibility of arranging such a room.
Making a simple heat accumulator
If you need a heat accumulator, making this equipment with your own hands will be quite simple. It should be based on the principle of functioning of a thermos. The presence of walls that are not able to conduct heat does not allow the coolant to cool for a sufficiently long period of time. For work, you will need to prepare a container,volume of which is 150 liters or more. Scotch tape, a concrete slab, insulation material, as well as copper pipes will be needed. The latter can be replaced with heating elements.
Specialist recommendations
When making heat accumulators for heating with your own hands, at the first stage you need to think about how the tank will look like. Most often, a metal barrel is used for its manufacture, which can be found even in your own area. The final volume can be determined individually, but you should not use a container with a capacity of less than 150 liters. This is due to the inexpediency of the work.
Production technology
If you decide to make a heat accumulator with your own hands, the drawings of which can be drawn up on your own, at the first stage the selected barrel must be put in order. To do this, it is thoroughly cleaned, debris and dust are removed from the inside. If there are areas where corrosion has already formed, then this defect must be eliminated.
Now the master will have to prepare the thermal insulation, which will wrap the container. The insulating material is responsible for keeping the heat inside the barrel for a longer time. Mineral wool is excellent for a homemade device. She needs to wrap the container from the outside, securing everything with tape. Additionally, the structure is covered with sheet metal, which can bereplace with foil. With it, you need to carefully wrap the container.
Internal stuffing
If you make a heat accumulator from a barrel with your own hands, it is important to decide which of the options will heat the water inside. You can use electric heating elements, as well as a coil, through the last of which the coolant descends. The first option is quite complicated, and besides, it is unsafe. That is why it is recommended to refuse it. As for the coil, you can make it yourself using a copper tube. The diameter of the latter should be 3 cm, while the length can vary from 8 to 15 meters. A spiral is prepared from this element, which is then placed inside.
Final works
The upper part of the container acts as a heat accumulator in the manufactured model. From it it is necessary to start up a branch pipe. At the bottom, another pipe is mounted, which will be introductory. Cold water will flow through it. These components of the system must be supplied with cranes. On this we can assume that a fairly simple device is completely ready for operation. However, before use, it is important to resolve one issue that is related to fire safety. The rules state that the unit should only be placed on a concrete slab, and if possible, the structure should be walled off.
Features of the connection
If you are wondering howto make a heat accumulator with your own hands, then you need to familiarize yourself with the connection features. In transit through the entire container, a return pipeline must pass, at the ends of which an inlet and outlet should be provided. Initially, it is necessary to connect the container and the return of the boiler to each other. Between them is a circulation pump. The latter is installed on the second side, like a shut-off valve. The supply pipeline is mated using the same technology as the previous one, but now the installation of heat pumps is not performed.
