By design, the typical heat accumulator is a steel tank with fittings at the top and bottomat t

he same time is the end of the coil made of copper tubing.The lower tubes are connected to the heat source, the top - with a heating system.Inside the unit is a liquid, which the user can use to solve problems relevant to him.



The principle of operation of the unit is built on a high heat capacity of water.In general, heat storage mechanism of action can be described as follows:

  • into the side wall of the vessel two pipes embedded.After one enters in the cold water tank on the water pipe or tank through a second heated heat transfer fluid is given in the radiators;
  • upper end of the coil installed in the tank, connected to the cold water pipe boiler, the lower - from the hot nozzle;
  • circulating through the coil, hot water heats the liquid in the tank.After turning off the boiler, heating the water in the pipes starts to cool down, but continues to circulate.On admission to the thermal receiver pushes accumulated there cool the hot liquid coolant in the heating system, so that the space heating continues for some time (depending on the capacity of storage) even when the boiler.

Important!To ensure the coolant flow system is completed with a circulation pump.

Key features heat store

The principle of heat storage

The principle of heat storage

storage tank has many useful features, including:

  • providing user with hot water;
  • normalization of temperature in the heated rooms;
  • improving indicators of efficiency of the heating system with a simultaneous decrease in the heating costs;
  • the possibility of combining several heat sources in a single circuit;
  • accumulation of excess energy, which produces copper, etc.

For all their advantages heat accumulators are only 2 drawback, namely:

  • resource accumulated warm liquid is directly dependent on the amount of used tank, but under all circumstances it is strictly limited and ends fairly quickly, so it is necessary to consider the issue of resettlement moreheating system;
  • more volume drives require a lot of space for installation, for example, a boiler room.

Installation scheme

Build a simple storage tank

simplest heatdrive operates on the principle of the thermos.The walls of the installation is carried out almost no heat and allow the water to stay warm for quite a long time.

To assemble this unit, we will need the following tools:

  • tank.The volume is adjusted individually, according to their needs and capabilities.Objective least - 150 l;
  • material for insulation.Excellent mineral wool;
  • adhesive tape;
  • copper tube coil manufacturing;
  • concrete slab or formwork boards and grout.

heat store can be collected on the basis of iron barrels.Volume, as noted above, is chosen individually, but to use a tank capacity of less than 150 liters is not much point.

first step

barrel Prepare for further work.If it is an old vessel, thoroughly cleanse it from various contaminants, and we clean the corrosion.

second step

wraps the outer walls of thermal insulation material.Well suited mineral wool.Wrapped insulation barrel is further wrapped with tape in several layers.

third step

envelops tank foil wrap.For fixing material also using adhesive tape.sheathe insulated sheet metal design, if desired.

fourth step

Making the coil through which the coolant will be transported.To do this, use the copper tube length of 8-15 meters (depending on the volume of the selected drum) and a diameter of about 20-30 m. Bend the tube into a spiral and place it inside the tank.The coil is connected to the boiler.Hereinafter, this coil will be heated and heat to give the resulting water in the tank.

fifth step

Making connections in the side walls of the storage device.After one pipe to the tank will be supplied cold water, go through another hot.Nozzles equip cranes for quick shut off water flow.

sixth step

Set the heat accumulator and carry out the connection.

For a better understanding of the order of the storage tank connection look at the diagram.

Important!The barrel can be put only on the slab of concrete.We buy the finished product or the molded base yourself.

Review process for you connect the drive to the heating system operating with 1 boiler.In the case of a larger number of heating units, the circuit substantially more difficult.The system will have to be equipped with pressure sensors and temperature and explosive safety valves, etc.By the assembly of this unit is only recommended to start with the appropriate skills and proper experience.

Heat accumulators effectively show themselves when used in a wide variety of heating systems.In each case, such a drive allows you to save on heating.

The most common thermal batteries equipped with solid-fuel heating system.The plant will contribute to a more economical fuel consumption and heating efficiency, as well as prevent premature wear of the radiators.

also want to heat storage and electric heating system, especially in regions with double-tariff electricity.At night, when the electricity is sold to the consumer at a more affordable cost, the battery will accumulate heat.During the day it will be possible for some time, turn off the boiler and storage tank flushing forces.

drives used in multi-loop heating systems.Thanks to them is provided between the distribution of the coolant circuits.Mounting of fittings can be formed at different heights, allowing to receive water heated to different temperatures.

few words about modernization



If necessary, the collected thermal battery can be easily upgraded us.There are several ways.

  1. We can install an additional heat exchanger from the bottom, through which energy is accumulated, the resulting solar collector.News for modern systems using solar energy for space heating.
  2. We can divide the inner space of the container into several interconnected sections that provide a more pronounced water stratification temperatures.News for multi-loop systems.
  3. We can slightly increase the budget and to perform thermal insulation polyurethane foam tank walls instead of mineral wool.This material will further reduce the heat loss.
  4. We can increase the number of nozzles and connected to the heat storage more complicated heating system, built on the basis of several independent circuits.News for heating systems serving large houses with the help of high-power boilers.
  5. We can install an additional heat exchanger for water accumulation.It can be used for various household and economic needs.
