Calculation of the heating system of a private house program

An effective heating system is essential for keeping your house warm during the winter. For both comfort and energy efficiency, choosing the appropriate heating system is essential when building a new home or remodeling an old one. We’ll explore how to use a program to calculate a private home’s heating system in this post, so you can make well-informed decisions to keep your house warm without going over budget.

Comprehending your home’s heating requirements is the first step in the computation process. A number of variables come into play, including the house’s size, insulation levels, weather, and individual preferences. Choosing the right heating system to suit your needs will be made easier with a careful evaluation of these variables.

Accurate estimates based on multiple parameters are one of the main advantages of using a program to calculate your heating system. These programs consider things like fuel sources (gas, electricity, solar), distribution techniques (ductwork, radiators), and heating system type (such as forced-air furnace, heat pump, or radiant floor heating).

When selecting a heating system, efficiency is a crucial factor. You can find the most cost-effective and environmentally friendly heating solution by using a program to estimate your home’s heating requirements. This guarantees that you will not only be warm and cozy but also use less energy and pay less in utility bills.

Furthermore, a lot of heating system calculation programs now have user-friendly interfaces and intuitive features thanks to technological advancements. This facilitates easier customization and optimization of the heating system design and opens up the process to both professionals and homeowners.

Step	Description
1	Measure the dimensions of each room in the house.
2	Determine the insulation level of walls, windows, and doors.
3	Calculate the total area to be heated in square meters.
4	Choose the desired indoor temperature for each room.
5	Consider the climate zone of the location.
6	Find the heat loss coefficient (U-value) for the building materials.

12	Adjust the heating system size if necessary to meet the heating needs of the house.

Practical use of programs for calculating heating

Finding the amount of thermal energy needed for each room is the goal of the heating system calculation. This is required in order to set the number of heating devices that correspond to the desired power. The total heat power for every room is also determined in the event that a boiler is to be used to heat the house through a water system.

These values are expressed and computed as the building’s total thermal losses as well as the losses in individual rooms. They are made up of heat losses via walls, ceilings, doors, windows, and other openings. In this instance, consideration must be given to the qualities of thermal insulation as well as the thickness of the materials and structures that allow for the exchange of energy with the outside world. The climatic zone and the standards for thermal losses for a variety of building types—domestic, residential, kitchen, bathroom, and corridor—are also taken into consideration. The same number of coefficients are used and a large number of different factors are considered.

When it comes to water heating, the most precise computations also take into account the layout of the pipe wiring and the radiator placement in each room. Remember that heating does more for the house than just provide warmth; it also provides hot water for various purposes. Every private residence has a kitchen with a sink, a bathroom, a shower, and maybe even a jacuzzi. For all of this, you need hot and cold water. As a result, energy requirements for heating the coolant must be considered for these objectives.

It goes without saying that the calculation of heating is laborious and challenging to do by hand. As a result, unique programs like Audytor Sankom SP, KAN (OZC), Overtrop CO, CJSC Stream, and others have been created. These programs can be downloaded for free or paid. They enable you to simplify the heating system calculation, account for all relevant factors, and eliminate involuntary errors.

Any program that calculates heating from the above must have an image of every room in the house as well as the wiring layout, including strapping, two- or single-pipe systems, the input of the structure’s requested characteristics, and other data. Even though modern designers use these software products, this option is still difficult for a non-professional.

Calculation program for averaged indicators

The internal heating system’s design

Simultaneously, programs and algorithms for calculating average indicators have been simplified. They are simple to use and provide enough accuracy to calculate the house’s heating needs.

The formula shown below is one possibility:

Qt: The room’s or the homes’ thermal losses in Tuesday

100 W/m 2 is the average specific amount of losses, or W.

S is the area in m 2 of the whole house or a particular room.

Z1 is the heat loss coefficient through windows, which varies based on the kind of glazing and has the values listed below:

• Ordinary double glass – 1.27.
• Double -glazed window – 1.0.
• Triple double -glazed window – 0.85.

The heat loss coefficient through walls, or Z2, varies based on the type of wall and the level of thermal insulation.

• Poor isolation – 1.27.
• Insulation with a thickness of 150 mm or a wall of 2 bricks – 1.0.
• Thermal insulation is good – 0.85.

Z3 – considers how thermal losses are influenced by the proportion of a room’s floor area to its glazing (windows) area. In turn, he is equal to:

Z4 is based on the average minimum temperature and takes the climate zone into consideration. What’s it worth?

Z5 – considers the quantity of walls that are close to the road. Is not:

• For one wall – 1.1.
• Two walls – 1.2.
• Three walls – 1.3.
• Four walls – 1.4.

Z6: Losses coefficient through ceiling, which varies based on the kind of room above the computed:

• The attic is cold – 1.0.
• The attic is warm – 0.9.
• Heated room – 0.8.

The Z7 model considers the height of the room ceilings.

Utilizing a floor-mounted gas cast iron boiler for heating

Now let’s finish the rough computation. Assume that the house has four 18 m 2 adjacent rooms. each possessing two outer walls. In every room, there are two double-glazed windows and a 20% floor to ceiling ratio. Three-meter-tall ceilings, brick walls, and a chilly attic above the rooms. The street has a temperature of -25°C. Since all of the house’s premises share the same parameters, you can quickly calculate the thermal losses of the entire structure using the data above. The building’s total area is S = 18 × 4 = 72 m 2.

Additionally, the coefficients are as follows: Z1 = 1.0, Z2 = 1.0, Z3 = 0.9, Z4 = 1.3, Z5 = 1.2, Z6 = 1.0, and Z7 = 1.05.

Qt is equal to 100 W/m. Two x 72 m 10614 W is equal to 2 x1.0x1.0x0.9 × 1.3 × 1.2 × 1.0 × 1.05.

Therefore, a boiler with a capacity of roughly 11 kW is needed to heat a house, for example.

The program that uses this formula for heating calculations is as follows. It only takes adding the necessary parameters to the appropriate fields to get the desired outcome.

Conclusion

The apartment’s radiator

The program’s and the suggested formula’s heating calculations rely on the use of average indicators. The approximate power of a private home’s heating system can be determined using this method. It is required to get in touch with specialist design organizations when dealing with complex heating, such as pool heating, air conditioning, and ventilation, as well as when calculating the heating system of production facilities and catering organizations.

When estimating using average indicators, it is acceptable to choose heating equipment approximatively. Similarly, it is wise to supply a specific amount of generator power rather than paying for the design organization’s services. because design services could be more expensive than other costs. In every situation, coordination with experts is required for the final complete set of the heating and equipment system.

3 features of the hydraulic calculation of the heating system of the house

Calculations: what are it and how to conduct them

This is a challenging phase in the heating system design process: hydraulic calculation. Using the same scheme, the heating structure calculation is performed for wooden or brick structures.

These days’ systems are built with premium components and let you monitor and manage even the smallest temperature variations.

By utilizing contemporary schemes, you can lower energy usage and improve design efficiency.

In order to calculate the hydraulics of pipelines, the following information is gathered:

1. The heat balance of heating buildings is calculated.
2. The type of heat exchanger is selected and the arrangement is performed.
3. A type of pipeline and reinforcement is selected.
4. The design drawing is performed. The graphic type of scheme displays thermal loads and distances of sites for calculating.
5. The circuit circulation circulation is mounted, which represents the closed ring.

You can obtain the following information through calculation:

• selection of the right section of pipes for the design of the structure;
• ensuring the hydraulic stability of equipment in different areas of heating;
• Pressure and water flow rate during the system.

The computation’s primary goals are to choose the pipeline line’s cross section and calculate pressure drops to help choose the appropriate pump.

The following steps make up a basic pipeline’s hydraulic calculation:

1. If the capacity of radiators is known, then a drawing of arrangements is made.
2. The consumption of the coolant and the diameter of the line is determined.
3. The calculation of the hydraulic resistance of the pipeline and the choice of the pump.
4. The volume of fluid in the design and dimensions of the expansion capacity is calculated.

The coolant flow rate is calculated using the following formula: G is equal to 860Q/t. Simultaneously, G represents the coolant flow rate, Q the battery power, and t the temperature differential between the supply and reverse lines. Shevelev tables are used in hydraulic calculations to find the pipes’ cross-section. Depending on the coolant flow rate, they show the diameter value.

In addition, indicators like the power of the pumping apparatus, a drop in temperature, and an indicator of pressure losses must be considered when calculating the water supply.

The heating system of a two-story building

The printing features are not included in this program. There are three projects available in the free version.

One crucial element of the regulatory framework is thought to be the pipeline pressure calculation. Precise data will be needed in order to select the appropriate control valves. This determines how the design is designed.

A good example of calculation for one (horizontal) and two -pipe heating system: resistance in the pipeline

The process for completing hydraulic calculations is shown in the calculation example. The pipeline system’s section with the highest heat loss is chosen. For instance, a basic heating system is employed. It has batteries and a boiler in it. There are ten radiators in the design.

The diagram was previously divided into areas. The pipes’ cross-section remains constant at every location. The pipeline line that runs from the boiler to the first device is included in the first section. The distance between the first and second batteries is included in the second. The remaining ones are split similarly.

The following is how radiator temperature is lowered. A portion of the heat in the first device is provided by the coolant, which drops by 1 kW. In this instance, thermal energy reaches a value of 10 kW on the first segment before declining.

The formula for calculating the coolant flow rate is q = (3.6*Que)/(C*(tr-to)).

In addition, C is the water’s specific heat capacity, and Que is the segment’s thermal load value. The value of this indicator never changes. 4.2 kJ/kg*C is the value.

TR is the fluid’s temperature at the station’s entrance, and to is its temperature at the output.

The system’s hot fluid moves at a certain ideal speed. It is between 0.2 and 0.7 m/s. In the design, traffic jams arise from the air if the figure falls.

It is important to take into account the material that the water line is made of when calculating speed accurately. The product’s inner surface roughness has an impact on speed.

Both a single-pipe and a two-pipe scheme are taken into consideration independently for circuit selection.

In the first scenario, the riser with the most equipment is chosen for the computation. For calculation, a loaded outline is chosen in a double-circuit structure. Since this element’s resistance is higher than the others’, calculations are made based on it.

The size of the pipeline is determined by a special estimate. In this instance, the scheme’s segments are all summed up. In a particular area of the structure, the coolant releases thermal energy, which is equal to the heat transfer of the pipeline line.

It is advisable to utilize specialized software for the planning and execution of the heating project, as it enables precise calculations of the structure’s thermal and hydraulic indicators.

The efficiency of the regulatory system is impacted by the application of accurate computations. A private home’s heating system can only be hydraulically calculated by a qualified professional.

Calculation of heating of a private house

There are multiple steps involved in the heating system calculation process.

Step 1. Calculation of heat loss at home

To calculate the required power for the boiler, the heating system, and each radiator independently, this data will be required. Use our online heat loss calculator to accomplish this. They must be computed for every room in a house that has an external wall.

Analysis. We obtain the specific heat loss in WT/sq.m. by dividing the computed heat loss of each room by its quadrature. They typically range from 50 to 150 W/sq.m. If your indicators differ significantly from those shown above, there may have been a mistake. The rooms on the upper floor lose the most heat, followed by the rooms on the first floor, and the rooms in the middle floors lose the least heat.

Step 2. The choice of temperature regime

It is preferable to use the 75/65/20 temperature regime for computations as it conforms with EN 442—the European standard for heating. Selecting it will ensure you never make a mistake. t.To. The majority of imported boilers are set up for it. There are also uses for low-temperature heating regimens.

Step 3. Selection of radiator power

You must select heating radiators based on the amount of heat loss that the rooms receive. Heat transfer tables for the most popular heating appliances in the CIS can be found on this website and can be adjusted for varying temperatures. Select the appropriate manufacturer by opening the "radiators" tab on the menu on the left.

Step 4. Hydraulic calculation

This stage’s work is boiled down to selecting the pipes and the circulation pump’s specifications. Hydraulic parameter calculation is a tedious process requiring specialized knowledge. For individual homes, selecting the pipe diameters in accordance with the table at the bottom of the Hydraulic calculation of the heating system page suffices. The following will be ensured by the table-based selection:

– pipelines with no noise;

– the rejection of their significance (assuming the heating system is installed correctly);

– The boiler will have an adequate circulation pump built in;

Step 5. Selection of the boiler

Maintaining efficiency and comfort in your private home requires knowing how to calculate the heating system correctly. Homeowners can make educated decisions about the size and kind of heating system they require by adhering to a structured program.

Evaluating the house’s thermal properties is one of the first steps in the calculation process. This entails taking into account elements like building materials, window quality, and insulation levels. Homeowners can measure these components precisely to ascertain the amount of heat loss in their building, which is essential for choosing the right size heating system.

It’s time to think about the available heating options after the heat loss has been computed. This could include more modern technologies like heat pumps or radiant heating in addition to more conventional systems like boilers and furnaces. Every option has advantages and disadvantages, so it’s critical to consider aspects like cost, environmental impact, and energy efficiency.

Sizing the heating system appropriately for the home comes next after selecting one. While undersized systems might find it difficult to heat the space sufficiently, oversized systems can result in inefficiency and higher energy costs. Making use of software applications or seeking expert advice can help guarantee that the system is appropriately sized for maximum efficiency.

Ultimately, keeping the heating system operating efficiently requires routine maintenance and observation. Regular inspections and maintenance can help detect problems early on and save expensive repairs later on. Monitoring energy consumption can also reveal important details about the effectiveness of the system and possible areas for development.
