How to make a heat accumulator for heating with your own hands - design, device features

Thermal accumulator for heating

Often a heat accumulator for heating is called a heat accumulator and a buffer device. They are designed to accumulate excess heat from various sources (fireplace inserts, solar collectors, various boilers, heat pumps, etc.), and also serve as a hydraulic decoupling of large heat flows used for heating.

Thermal accumulators create a temporary balance between the production of heat sources and its use by consumers.

Where is a heat accumulator used and how is it designed?

A thermal energy storage device is nothing more than an insulated iron tank with pipes for connecting water heating lines. The buffer tank performs 2 functions: it accumulates excess heat and heats the house during periods when the boiler is inactive. The heat accumulator replaces the heating unit in 2 cases:

  1. When heating a home with a stove with a water circuit or a boiler that burns solid fuel. The storage tank works for heating at night, after wood or coal burns out. Thanks to this, the homeowner can relax in peace, rather than running to the boiler room. It is comfortable.
  2. When the heat source is an electric boiler, and electricity consumption is recorded using a multi-tariff meter. Energy at the night rate is half the price, so during the day the heating system is completely powered by the heat accumulator. It's economical.

Important point. Tank - hot water accumulator increases the efficiency of a solid fuel boiler. After all, the maximum efficiency of a heat generator is achieved with intense combustion, which cannot be constantly maintained without a buffer tank that absorbs excess heat. The more efficiently wood is burned, the less it is consumed. This also applies to a gas boiler, whose efficiency decreases in low combustion modes.

A storage tank filled with coolant operates on a simple principle. While the heat generator is heating the rooms, the water in the tank is heated to a maximum temperature of 80-90 ° C (the heat accumulator is charging). After the boiler is turned off, hot coolant from the storage tank begins to flow to the radiators, providing heating for the house for a certain time (the heat battery is discharged). The duration of operation depends on the volume of the tank and the outside air temperature.

Assembly diagram of a heat accumulator at the factory
How does a factory-made heat accumulator work?

The simplest factory-made storage tank for water, shown in the diagram, consists of the following elements:

  • the main tank is cylindrical in shape, made of carbon or stainless steel;
  • thermal insulation layer 50-100 mm thick, depending on the insulation used;
  • outer skin – thin painted metal or polymer cover;
  • connecting fittings embedded into the main container;
  • immersion sleeves for installing a thermometer and pressure gauge.

Note. More expensive models of heat accumulators for heating systems are additionally equipped with coils for hot water supply and heating from solar collectors. Another useful option is a block of electric heating elements built into the upper zone of the tank.

Thermal accumulator for heating

Review

These heat accumulators for heating boilers have a steel body and heat-resistant insulation on top. Underneath there are blocks that accumulate heat. They are made of composite material with high thermal conductivity, which are heated using heating elements.

Heat accumulates at night when reduced electricity rates apply. Then, during the day, it is used to heat the room.

For faster heating, a fan is built into the design.

Important: In order to regulate the room temperature, in other words to control the discharge, you need a built-in regulator, which is not included in the package, so it must be purchased separately.

There is a switch on the front panel, thanks to which it is possible to manually adjust the charge volume.

In order to be able to set the charging start and end time (during the energy payment benefits are valid), it is necessary to install an electric siren (signal) or a timer. It's also not included in the kit. It can be purchased for an additional fee.

Technical indicators

  • Power value, kW – 2.0;
  • Dimensions, mm – 650x605x245 (HxWxD);
  • Weight, kg – 118;
  • Operating temperature range, degrees - +7-+30;
  • Manufacturer – Germany;
  • Mounting type – floor;
  • Warranty period – 3 years.

The purpose of the model is to regulate the output of heat received from one or another source of heat for effective heating of the room.

Device

There is a tubular heater inside, made of high-quality steel. It heats the stones, which are capable of accumulating heat; they release it, cooling naturally, to the air passing through them under the influence of a fan.

By installing a sensor in a room, you can regulate heat with high precision, saving (due to the built-in battery) a significant portion of electrical energy.

Comfort mode is set by the power regulator.

TOP 8: HAJDU AQ PT 500

Thermal accumulator for heating

Hajdu buffer storage tanks (also known as heat accumulators) are designed to supply hot water to a closed heating system. Depending on the type chosen, heaters using gas and fuel oil, boilers using solid fuel and biomass for operation, solar panels and fuel pumps can be connected to them.

The volume of such heating structures supplied to the retail chain varies from 300 liters to 870.

There are many varieties of them:

  • AQ PT series (empty tanks);
  • AQ PT C (with coil);
  • AQ PT C 2 (combined).

Device

The inside surface of the tank is not covered with a protective anti-corrosion layer, which is why it is recommended to fill the tank with water exclusively for heating.

Additionally, thermal insulation for the structure is purchased, since the package does not provide it. It is made of soft polyurethane foam. Its thickness is 100 - 120 millimeters.

For the manufacture of the casing, artificial leather was chosen. The insulation and casing can be quickly removed if the device does not fit through the door. Without them, there is no such problem even if we are talking about a heat accumulator of maximum volume.

Installation at the place where the device will be used is carried out in the same way, without them. With such designs, no unforeseen situation will arise.

They are quite capable of providing the space with warmth. At the same time, the efficiency of the generated energy increases many times.

Options

  • Manufacturer – Hungary;
  • Weight – 99 kg;
  • Warranty – 3 years;
  • LxH – 650x1675 mm;
  • The highest possible pressure in the tank and storage tank is 3 bar and 0.3 MPa;
  • The installation size of the heating element, water and temperature sensor is 1″1/2, 1″1/2 and 1/2.

How to make a heat accumulator with your own hands

This question arises when a person finds out the price of such equipment, depending on the number of coils and the material of manufacture, it ranges from 400-1500 cu. Which is not affordable for everyone.


Device diagram

TA is a cylindrical or rectangular container made of metal. The dimensions are determined by the required volume obtained as a result of the calculations given earlier. Wall thickness 2-3 mm.

The sheet is cut using a plasma cutter, grinder, guillotine or welding machine. It is also sewn together using welding. Maximum weld quality is ensured by gas welding, but inverter welding can also achieve the desired result. In any case, the quality of the welds will need to be checked under pressure of up to 4 atmospheres. The end walls of the cylinder are closed with flat metal circles of the same thickness.

Steel or stainless steel

Today on the market you can purchase such containers from both black steel and stainless steel. Manufacturers claim that it is worth taking only the last option since it is not subject to corrosion, but it also costs 2-2.5 times more. What to choose? In fact, there is no money for stainless steel, feel free to take ferrous metal. A thickness of 3 mm will last for many years, since this container is constantly filled with water and the oxygen it contains is not enough for corrosion to form.

The only problem is that when the water is drained, dampness remains inside for a certain time. But the metal thickness reserve is enough for this not to be a problem. From my experience: heat accumulators have been in operation for about 10 years, no problems with corrosion were found during the audit.

A curved smooth or corrugated pipe acts as a heat exchanger. Purchasing a magnesium anode will eliminate the danger of quickly covering the structure with corrosion.


Example drawing

It is necessary to prepare a drawing in advance and mark the inlet and outlet openings for inserting the heat exchanger and two more connections to the main circuit. Input on top, output on bottom. Fittings cut into the walls. Two additional holes with pipes must be made in the bottom and top cover. One for draining the coolant, the second for the air vent (will eliminate excess pressure inside the tank).


To ensure that the container, especially if the shape is not cylindrical, does not swell after filling, stiffening ribs are installed around the perimeter, at a distance of 320-380 mm from each other (outside the tank). They are made from a metal strip 3 mm thick. Inside, each ring is tightened by two diametrical wall reinforcements, perpendicular to each other. The same is done with the end walls (the amplifier connects the centers of the circles).

The entire structure is welded. Supports will be required for installation. They will be fitted to the bottom. In these places, additional stiffening ribs from the same strip are attached to the outside of the tank so that the bottom does not deform under the weight of the tank. The fittings are threaded (if the connection to pipes is planned to be made using couplings). This can be done before installing them on the TA.

As an alternative, a welded contour connection is used. This is inconvenient from a maintenance point of view. If the TA fails, the pipes will have to be cut. The coupling can be unscrewed, and after repair, everything can be re-installed. If alloys of non-ferrous metals are used as a coil, argon welding will be required.

When the system involves the use of several heat exchanger spirals, they are installed one inside the other. That is, the diameter of the first is less than the diameter of the second. A design with an arrangement one above the other is possible, if the height of the ceilings in the room allows it.

The material for the tank can be carbon steel with an anti-corrosion coating applied by galvanic method. It's cheaper than making a stainless steel tank. But the latter will last longer. The only weak spot is the welding seams. It's better to process them. Naturally, the welding machine must be able to weld stainless steel.


As an additional equipment, you can install an electric heating element. By turning it on, you will reduce the startup and warm-up time of the system. Control and measuring instruments will also not be superfluous (thermometer, coolant level controller, etc.). A safety air release valve is used as a device to ensure the safe operation of the heat accumulator. Such a system is reliable, durable and unpretentious.

Coil manufacturing


To manufacture this element, a copper tube with a diameter of 20-30 mm is used. The shape should be cylindrical, since they are always a weak point in systems with constantly circulating water.

To make such a spiral structure, you can use a simple device in the form of a wooden-plywood frame on which a tube is wound.

Threaded fittings must be welded or soldered on both edges of the tube for further connection to the system. For soldering, it is best to use soft solder.

TOP 7: HAJDU AQ PT 1000 C

Thermal accumulator for heating

Description

The tank of this heat accumulator is designed for 1000 liters. The device is designed to work together with a solar collector and a solid fuel boiler.

The buffer design, in addition to storing excess heat generated by a solid fuel boiler or any other alternative energy source, can redirect it to a heat accumulator.

Among such additional sources, solar batteries are actively gaining popularity, the cost of which is not as high as it might seem.

Their advantage is that they supply practically free heat all year round, even with little lighting. Even in cloudy weather, the heating system can receive tens of kilowatts of energy from them.

Design

Inside the Hajdu AQ PT 1000 C tank there is a heat exchanger in the form of a spiral. Its area is 4.2 square meters. The coolant heated by the sun's rays, flowing through the coil, gives off its heat, which is directed to the heating system for heating.

The coolant is supplied and removed through pipes that are located on the same vertical line, which is important because boiler room space is saved.

The dimensions of the device allow it to function in tandem with a solid fuel boiler, whose power is 25-35 kW.

Important: the system that ensures the accumulation of heat by a buffer capacity is only capable of functioning in a heating system with a forced cycle, and is not suitable for a gravity system.

The designers of the Hoidu brand did not limit themselves to the described function of the device, i.e. the ability to accumulate heat. Therefore, they provided a technological hole that makes it possible to install 2, 3, 6, 9 - kilowatt heating elements. The importance of this solution is the ability to increase the time between downloads. This was appreciated by those living in country cottages and dachas.

We recommend:

  • Portable phone chargers: advantages, features, price - TOP 7
  • Thermal accumulators: purpose, features, price - TOP-6
  • TOP 6: inexpensive solar collectors for heating and heating swimming pools, prices and where to buy

Now they can load cheap heat, i.e. load the energy storage device at a discounted rate. There is no need to insert an electric boiler into the heating system, because the heating elements heat the storage tank directly, releasing the heat accumulated during the night into the system during the day.

To ensure that the price of the heat accumulator is affordable to a wide audience of users, the developer does not equip it with external insulation, which can always be ordered as an option, just like heating elements.

Inner surface

On the inside, the walls do not have an enamel coating, like boilers with indirectly heated water heaters, so heat accumulators are not recommended for use in hot water supply.

Choosing a heat accumulator

TA is chosen when designing a heating system. Heating engineers will help you choose the right heat accumulator. But, if it is impossible to use their services, you will have to choose yourself. It's not difficult to do this.

Heat accumulator for solid fuel boiler

The main criteria when selecting this device are considered to be the following:

:

  • heating system pressure;
  • volume of buffer capacity;
  • external dimensions and weight;
  • equipping with additional heat exchangers;
  • possibility of installing additional devices.

Water pressure (pressure) in the heating system is the main indicator. The higher it is, the warmer it is in the heated room.

Taking this parameter into account, when choosing a heat accumulator for solid fuel boilers, attention is paid to the maximum pressure that it can withstand. The heat accumulator for a solid fuel boiler, shown in the photo, is made of stainless steel and can withstand high water pressure. Buffer capacity

The ability to accumulate heat for the heating system during operation depends on it. The larger it is, the more heat will accumulate in the container. Here you need to take into account that raising the limit to infinity is pointless. But if there is less water than normal, the device simply will not perform its heat storage function. Therefore, to correctly select a heat accumulator, you will have to calculate its buffer capacity. We'll show you how it's done a little later.

Buffer capacity volume. The ability to accumulate heat for the heating system during operation depends on it. The larger it is, the more heat will accumulate in the container. Here you need to take into account that raising the limit to infinity is pointless. But if there is less water than normal, the device simply will not perform its heat storage function. Therefore, to correctly select a heat accumulator, you will have to calculate its buffer capacity. A little later we will show how it is done.

External dimensions and weight. These are also important indicators when choosing a TA. Especially in an already built house. When the heat accumulator for heating has been calculated and delivered to the installation site, a problem may arise with the installation itself. In terms of overall dimensions, it may simply not fit into a standard door opening. In addition, large-capacity heating units (from 500 liters) are installed on a separate foundation. A massive device filled with water will become even heavier. These nuances need to be taken into account. But the way out is easy to find. In this case, two heat accumulators are purchased for solid fuel boilers with a total volume of buffer tanks equal to the calculated volume for the entire heating system.

Equipped with additional heat exchangers. If the house does not have a hot water system or its own water heating circuit in the boiler, it is better to immediately purchase a heat exchanger with additional heat exchangers. For those living in the southern regions, it will be useful to connect a solar collector to the heat exchanger, which will become an additional free source of heat in the house. A simple calculation of the heating system will show how many additional heat exchangers it is desirable to have in the heat accumulator.

Possibility of installing additional devices. This implies the installation of heating elements (tubular electric heaters), instrumentation (control and measuring instruments), safety valves and other devices that ensure uninterrupted and safe operation of the buffer tank in the device. For example, in the event of an emergency extinguishing of the boiler, the temperature in the heating system will be maintained by heating elements. Depending on the volume of heating of the premises, they may not create a comfortable temperature, but they will certainly prevent defrosting of the system

The presence of instrumentation will allow timely attention to possible problems that have arisen in the heating system

TOP 5: S-Tank AT 300

Thermal accumulator for heating

Review

The purpose of the design is to accumulate heat given off by various sources and organize multivalent heating systems. This means that if it is necessary to combine work from two or more heat sources (a carbide boiler, for example, with an electric or gas boiler), the model will be quite effective.

Tank

The device for storing heated water is made of carbon steel. For the heating system, it acts as a hydraulic separator and improves the flexibility of the latter.

Pairs perfectly with the following boilers:

  • solid fuel;
  • using biomass as fuel;
  • pellet;
  • electrical;
  • gas.

And also with heat sources:

  • fireplaces with water jackets;
  • fuel pumps.

Insulation

It is made using NOFIRE technology and environmentally friendly polyester material, 100% recyclable. Insulation thickness 70 mm. Its main advantage is considered to be high heat transfer and fire resistance (class B-s2d0 according to European standards).

The tank is also protected from the outside, for which the developer uses plastic lining (up to 1000 l) and fabric lining (more than 1000 l), the color range of which is very diverse.

The top of the tank is painted with high temperature resistant paint. The internal walls do not allow paint to be applied according to existing requirements. Optionally, a zinc-containing composition can be applied to the inner walls. This is done in order to store hot water.

Hole size

To connect instrumentation devices, holes with 1 ½ “internal threads are provided, turned to each other at right angles.

Recommendations for choosing a battery manufacturer for UPS for boilers

To choose the right battery for the UPS of gas heating boilers, we will consider the best manufacturers of AGM and gel batteries in three segments:

  1. Budget.
  2. Average.
  3. Premium
  • The best batteries for UPS of gas boilers in the budget price segment are models of the Energy brand. These batteries are manufactured in China under Russian control. The production line of Energy batteries for UPS boilers contains less than 10 models. If it is necessary to obtain greater capacity, several Energy batteries can be connected in parallel.
  • Delta batteries are the best choice of UPS batteries for boilers in the mid-price segment. Delta brand batteries are produced at large Chinese factories of the Vision group of companies. The quality of products is controlled by Russian Delta Battery engineers. The produced range of Delta AGM and gel batteries contains more than 10 different lines, each of which contains dozens of models with capacities from 1 Ah to 3000 Ah .
  • In the premium segment, the best batteries for uninterruptible gas boilers are models from the Yuasa brand. The batteries of the Japanese company Yuasa are manufactured in Taiwan, which ensures high quality products. Yuasa batteries have proven themselves to be the best, both in terms of reliability and the number of charge-discharge cycles. However, their price is approximately twice that of similar Delta models.

We recommend choosing Delta AGM batteries .

TOP 4: S-TANK AT AT-1000

Thermal accumulator for heating

The storage tank, which occupies 4th place in the TOP-10, serves the same tasks as those described above - accumulating heated water.

Description

  • The material used for the body is carbon steel;
  • Country of origin: Belarus;
  • Weight – 131 kg;
  • Height – 2035 mm;
  • Diameter – 92 cm;
  • Volume – 1000 l;
  • The pressure in the tank and the highest temperature are 6 bar and 95 degrees.

Thermal accumulator for heating

The buffer heat accumulator does not have a heat exchanger. Its volume is 1000 liters, which allows the device to be used with 6-10 kW boilers intended for small areas. A low-power solid fuel boiler is most suitable for the specified volume of coolant.

The structure is protected on top by 70 mm of thermal insulation, which is closed with a plastic casing with an aluminum latch for ease of transportation, installation and dismantling. There are 8 holes with one and a half inch internal threads for supplying and discharging boiler water.

The pipes are turned at an angle of 90 degrees and located at different heights for the convenience of connecting different heating circuits and installing the storage tank in a corner.

In addition to them, there are 4 more half-inch holes, which are intended for thermomanometers and temperature control sensors. The pressure inside the working area is 6 bar. It is sufficient for the normal functioning of the drive.

Price

Multi-circuit heating systems with heat accumulators

Another indisputable advantage of the storage tank is the potential ability to operate it as a hydraulic arrow (read: “Hydraulic arrow for heating”).
This function is very necessary, since due to the fact that the tank body is equipped with at least four pipes, it becomes possible to select coolant with the desired temperature at one or another level of the storage tank. This will make it possible to equip a high-quality high-temperature circuit equipped with radiators, as well as heating with low temperatures, such as in a heated floor.

However, we should not forget about pumps that have heating control circuits, since the temperature at different levels of the storage tank at different times of the day is known to be different.

At the same time, the function of the pipes is not limited to outlets for heating circuits. Several boiler systems equipped with different types can be connected to one heating accumulator.

Homemade heat accumulator: advantages, design, connection diagram to the heating system

Among craftsmen, improving the heating system has recently become one of the most popular topics. The material used for the heat accumulator is 200 liter metal barrels, containers for technical fluids and even ready-made solutions - barrels from decommissioned fire trucks and army water-oil heaters. At the same time, the latter options are considered the most preferable - the containers already have thermal insulation and sufficient volume. So, from an AC-40 fire truck, the tank has a capacity of 1.5 tons, an army trailer holds 1 ton of water.

When designing, different calculation methods are used, but the fastest and easiest is to use an online calculator, into which you just need to substitute the requested indicators.

At the same time, despite the apparent simplicity of correctly calculating and installing a heat accumulator for a solid fuel boiler, it is also important to correctly select other equipment - pumps, valves, taps, electronic control devices.

Short review

The best model TOP-10 is recommended for use in various types of heating systems.

Stainless steel is used to make a cylindrical storage tank. Therefore, the device will serve for a long time, reducing heating costs.

Advantages

The model has enough of them:

  • simple maintenance and installation;
  • fast heating of water, independent of conditions;
  • protection against overheating, so operation is permitted even in commercial buildings;
  • unique parameters and versatility, the choice of which is determined by the size of the heated room;
  • continuous heat accumulation thanks to built-in heat exchangers;
  • compatibility with heat supply sources of any type.

Additional thermal insulation can improve efficiency. The insulation can be polyurethane foam or mineral wool, which slow down the cooling of the coolant.

By using a combined heating device you can significantly reduce costs. Each user can maintain a comfortable temperature by choosing a heat storage device based on parameters such as power, design features, volume, etc.

Characteristics

  • Manufacturer – Belarus;
  • Weight – 105 kg;
  • Size in diameter – 78 cm;
  • Height – 157 cm;
  • Tank volume – 500 l.

Advantages of using thermal accumulators

The installation of a heat accumulator is aimed at achieving the following goals:

  • The boiler can be heated at any convenient time;
  • The laying of each subsequent batch of fuel can be postponed for some period of time;
  • The amount of fuel spent on heating the building will be reduced.

A buffer tank (heat accumulator) built into the boiler allows you to maintain a comfortable microclimate in the house and at the same time reduce fuel consumption for heating. If such a system is supplemented with sensors and thermostats, the savings will be maximum - when a certain temperature is reached, the heat supply to the heating circuit simply stops.

DIY buffer tank for a solid fuel boiler

The energy generated by the boiler will be stored in a heat accumulator until it is needed. As soon as this happens, heat will begin to flow directly into the heating, bypassing the boiler. Increasing the battery capacity will extend the battery life of the heating system.
