Strapping solid fuel boiler: the correct scheme with a boiler and with a heat accumulator

Having an efficient system is essential for both cost-effectiveness and comfort when it comes to heating our homes, particularly in colder climates. Solid fuel boilers are a common choice because of their dependability and affordability. However, correct installation is essential to maximizing its effectiveness and guaranteeing peak performance. In this post, we’ll examine the proper method for strapping a solid fuel boiler, paying particular attention to two crucial configurations: one that just includes the boiler and the other that also includes a heat accumulator.

Let’s first review the fundamentals of a solid fuel boiler. These boilers provide heat for your house using solid fuels like coal, wood, or pellets. Since they need manual fuel loading, unlike gas or oil boilers, they are a popular option in places where such resources are affordable and easily accessible. In order to ensure effective heat distribution, the boiler must be properly strapped to your home’s central heating system.

The basic method of strapping a solid fuel boiler without a heat accumulator is to connect it directly to the heating system. With this configuration, heat can be transferred instantly from the boiler to the underfloor heating system or radiators, providing warmth when needed. To avoid overheating and preserve system integrity, safety precautions like temperature controls and pressure relief valves must be included.

However, adding a heat accumulator to the strapping scheme has additional advantages, especially in terms of comfort and energy efficiency. A heat accumulator, sometimes referred to as a thermal store, serves as a buffer, holding onto extra heat produced by the boiler for use at a later time. By progressively releasing the stored heat to the heating system when required, boiler operation frequency can be decreased and fuel efficiency can be maximized.

It is essential to design the strapping scheme with a heat accumulator with the right size and placement. Without sacrificing its efficiency, the accumulator should be able to hold enough extra heat. Furthermore, the heating system’s well-planned arrangement guarantees effective heat distribution and reduces energy loss during transfer.

In conclusion, correct installation is crucial, regardless of whether you go with a straightforward strapping scheme that only includes the solid fuel boiler or decide to add a heat accumulator for increased efficiency. You can get the most out of your heating system and maximize its cost-effectiveness by adhering to the right scheme and taking safety, sizing, and placement into consideration.

Boiler Only Setup Boiler with Heat Accumulator Setup
This setup includes only the solid fuel boiler. This setup involves both a solid fuel boiler and a heat accumulator.
The boiler heats water directly, which is then circulated through the heating system. The boiler heats water, which is then stored in a heat accumulator tank for later use.
It"s a simpler system but may lack efficiency in maintaining consistent heating. This setup allows for better heat distribution and more efficient use of the solid fuel.

Peculiarities of solid fuel boiler operation

This kind of heater has advantages and disadvantages just like any other equipment.

  1. Do not require connection to the power supply network, that is, they are considered autonomous systems.
  2. Affordable price of the equipment.

The use of these kinds of boilers is thought to be economically viable given the low cost of fuel.

The minuses are responsible for the following:

  1. Fire protection of the surfaces adjacent to the unit is required.
  2. Control of the combustion process is rather complicated.
  3. Lack of automatic fuel supply, although if desired, this issue can be solved.
  4. It is desirable to ensure low humidity in the room where solid fuel is stored.

The TTCO works on a straightforward principle: heat is released when wood or other raw materials burn in the furnace. This heat then heats the water that is circulated through the pipes. Special devices are used to remove the combustion products created during this process from the equipment. The gases go through the chimney, and the mineral part (ash and soot) go through the ash pan and soot collector.

Whether you’re using a solid fuel boiler system with a heat accumulator or a boiler alone, we’ll go over how to set it up properly in this article. For effective heating and to make sure your house stays warm throughout the winter, choosing the appropriate strapping scheme is essential. We’ll break down each step, discuss why it matters, and provide advice on how to set everything up as best you can. The comfort and energy efficiency of your home can be greatly improved by knowing the proper strapping scheme, whether you’re thinking about replacing an outdated system or installing a new one.

Purpose of strapping

Similar to other equipment, TTC requires proper component integration and peripheral connection to function as a single unit.

The following tasks are carried out by the TTCO’s strapping:

  1. Reduction of negative impact on others in case of any emergency situation.
  2. Uniform distribution of the allocated heat throughout the heating system circuit.
  3. Reduction of the periodicity factor in the operation of the TFCS, associated with the unevenness of fuel combustion.

Boiler operation becomes safer and more efficient as a result of all these factors.

What elements make up the strapping

There is just no single scheme of connection and equipment for all heated buildings. As a result, a separate project is completed before beginning the home’s heating system installation.

The following is a list of requirements for the piping:

  1. Boiler.
  2. Radiators or batteries.
  3. Expansion tank.
  4. Pipes (cast iron, copper, steel, polypropylene).
  5. Fittings and fixtures (including Maevsky cocks and pressure gauges).
  6. Circulation pump (if forced movement of the heat carrier).
  7. Bypass lines.
  8. Thermostat.

Rules of boiler piping

The HTCOs must be correctly tied in for the heating system to function as a whole in an efficient and dependable manner.

It is imperative to consider multiple significant points:

  1. In order to avoid condensate formation, the temperature difference between the supply and return should not exceed 20°C.
  2. Installation of pressure gauges will allow to control the pressure within the limits specified in the instructions to the equipment and regulatory documents.
  3. To maximize efficiency, connections should be sealed.
  4. It is not allowed to use combustible materials in the elements of piping.
  5. In order to avoid scale formation and clogging of pipelines leading to equipment failure, the cleanliness of the heat transfer medium must be ensured.
  6. If the building is higher than one floor, forced circulation of the coolant should be used.

Typical schemes of piping

Despite having many similarities, every home and boiler room are unique, necessitating the development of a unique project for proper heating plumbing. These projects follow standard schemes that represent the fundamental views of system installation under various circumstances.

Open type system with natural circulation

This is the most widely used scheme, sometimes referred to as gravitational. It has benefits and drawbacks of its own.

  1. Efficient operation.
  2. Simplicity of installation.
  3. Relatively low cost.
  4. High safety.
  5. Autonomy.

The gravity scheme necessitates the installation of an expansion tank to collect excess coolant because heated water has a tendency to expand.

  1. Difficult to manage.
  2. The need for constant monitoring of the system.
  3. Increased fuel consumption.

The return inlet to the boiler in an open system needs to be at least 0.5 meters below the radiators.

Closed system with natural movement of the coolant

On the return pipe, a diaphragm tank must be installed as opposed to open circulation. Its size must be 10% larger than the system’s total heat transfer fluid volume in order for it to operate efficiently.

In order to be able to relieve pipelines of excessive pressure (more than 2 atm).) It is necessary to install and link a safety valve to the sewage system.

System with forced circulation

The use of a pump characterizes a forced circulation system. This guarantees that the temperature is constant throughout. Additionally, pipeline slope can be reduced by using circulation equipment.

Provide bypass lines that avoid the equipment in the event of a voltage drop or pump failure in order to keep the heating system operating as intended. A circulation pump is placed on the return for security and to improve the operational longevity and dependability.

Scheme with buffer tank

The purpose of the heat accumulator-based solid fuel heating boiler scheme is to prevent the working fluid from boiling and to maintain a steady temperature within the system (because the TTC is not well controlled, constant fuel and draught control is necessary).

A hermetically constructed tank placed between the boiler and the customer is the heat accumulator. The gadget works on the principle of storing extra heat in its own volume, which it can then release into the system as needed.

A mixing unit, a three-way valve equipped with a temperature sensor, controls the coolant temperature.

Circuits with three-way valve

There is a circuit for an emergency supply of cold water to the heat exchanger or to a special coil installed inside the equipment to further prevent the heating boiler from overheating.

The equipment inside the heat-exchange apparatus that includes a temperature sensor and a three-way valve allows this unit to operate. The sewer system receives the heated water discharge.

With installation of indirect heating boiler

Any connection scheme can be used to pipe a solid fuel boiler with an indirect heating boiler. To provide hot water, cold water is heated in a boiler.

Every appliance that uses hot water has its connection to the system made in parallel with the water heater. Here, it’s crucial to keep in mind that, in order to maximize efficiency, the unit should have a three-way valve that can be used to cut off the water output if it hasn’t heated up yet.

Collector circuit

Collectors are used to connect multiple heating branches in parallel at the same time. For instance, when linking multiple floors’ worth of radiators—each with its own branch—and underfloor heating to a single unit. д.

The use of manifolds (combs) offers up a wide range of options for modifying the system, improving efficiency and reliability despite the apparent complexity.

What are emergency and control systems for?

By adding emergency and regulation units to the plan, the heating system can be secured.

  1. Protection against overpressure.
  2. Thermoregulation.
  3. Protection of equipment from excess heat.
  4. Prevention of condensate formation.

How they are connected

It is essential to install the nodes correctly in order to guarantee that they qualitatively serve their intended purpose.

The emergency section consists of:

  1. Safety valve. Used for overpressure relief. It is installed on the supply outlet of the boiler.
  2. Heat exchanger. Used to prevent overheating of the boiler. Installed either in the boiler design by the manufacturer or on the hot water supply pipe.
  3. Bypass. Used to prevent overheating and boiling of the coolant. Must be installed in units with pumps and auxiliary equipment.

A pressure regulator and a thermostat, both mounted on the return, control the system. They function to prevent pressure rise and to keep the system’s temperature constant.

Nuances of strapping installation

Maevsky cocks are fitted in all heating schemes, barring open ones, at the highest points in order to extract air.

In order to guarantee the system’s functionality, a few details need to be considered:

  1. The surface for boiler installation should be strictly horizontal.
  2. The size of the base – the size of the unit + 10 %.
  3. An expansion tank should be used in any heating system with a boiler.
  4. The preferred connection of devices – threaded connection.
  5. Connection of the heating unit should only be carried out using steel or copper pipes.

Selecting the appropriate solid fuel boiler strapping plan is essential for effective home insulation and heating. Understanding your options will help you optimize your heating system for maximum efficiency and economy, whether you choose to use a boiler by itself or in conjunction with a heat accumulator.

It’s crucial to make sure that the boiler is installed and sized correctly when thinking about the scheme with just the boiler. For the house to have uniform heat distribution, the boiler should be positioned in the center. Additionally, to reduce heat loss and increase efficiency, the piping system must be properly insulated. To guarantee the boiler’s longevity and peak performance, routine maintenance is also required.

A heat accumulator integrated into the system has various advantages, such as improved heating flexibility and energy efficiency. The boiler’s excess heat is stored in the heat accumulator and is subsequently released gradually as needed. Over time, this lowers the frequency of boiler firing and helps to maintain a more stable temperature inside the house, saving money and fuel.

The right planning and execution are essential when putting a heat accumulator scheme into action. Installing the accumulator in a spot that promotes effective heat distribution and matching its size to the household’s heating requirements are essential. Minimizing heat loss and optimizing energy savings also require insulating the accumulator and nearby pipes.

In conclusion, careful planning and installation are crucial for the best possible heating and insulation of your home, regardless of whether you choose to integrate a heat accumulator or stick with a scheme that simply uses a solid fuel boiler. You can design an economical and efficient heating system that will keep your house toasty and cozy all year long by being aware of the benefits and drawbacks of each option.
