Water heating system device in a country house

Any country house’s ability to remain functional and comfortable depends heavily on its ability to heat water effectively and consistently. An efficient water heating system is essential for cooking, heating radiators, and taking showers. We’ll examine the main parts and operation of a water heating system designed for rural homes in this post.

The water heater is the central component of any water heating system. The selection of a water heater is crucial for a country home, taking into account variables like the property’s size, fuel accessibility, and energy efficiency. There are several options to fit different needs and preferences, ranging from solar-powered systems to tankless models and conventional tank-based heaters.

For many homeowners in rural areas, particularly those who live in areas with severe winters, insulation is essential to preserving the effectiveness of their water heating system. In order to prevent heat loss and guarantee that hot water reaches its destination without requiring needless energy consumption, pipes, tanks, and the building itself should be properly insulated.

The distribution system is an additional important component of a country house water heating system. This comprises the pumps, valves, and pipes that move hot water from the heater to different locations around the house. For all taps and fixtures to have constant water pressure and temperature, this network must be installed and designed correctly.

Furthermore, a country home’s water heating system’s operational costs and environmental impact can be greatly decreased by incorporating renewable energy sources like geothermal heat pumps or solar thermal panels. By utilizing natural resources, these technologies offer a sustainable and environmentally responsible substitute for traditional heating techniques.

In conclusion, a country house’s ability to remain functional and comfortable depends on having a well-thought-out water heating system. Through meticulous component selection, adequate insulation, and consideration of renewable energy sources, homeowners can customize a dependable and effective system to suit their unique requirements and inclinations.

Ensuring effective heating and insulation is essential when installing a water heating system in a country home. In addition to offering comfort, a well-designed system lowers environmental impact and saves energy. In order to do this, take into account elements such as the kind of heating system (heat pumps or boilers), materials for pipe and tank insulation, and intelligent controls for efficient use. Optimizing the system’s lifespan and performance requires proper installation and maintenance. When used properly, a water heating system can effectively serve the needs of the home while also fostering comfort and sustainability over time.

How the system works

You should be aware of the layout and operating principles of water heating systems if you intend to provide heat for the building on your own. Any scheme consists of three parts:

• installation producing thermal energy and transmitting it to water;
• pipeline wiring;
• heating devices located in heated rooms.

Remark: Taps, balancing valves, mixing valves, and other controversial reinforcement are invariably a part of the wiring. The boiler may have additional equipment installed separately or as part of it, such as an expansion tank and circulation pump.

The system works on the basis of heat being transferred from the source to the heating devices through a liquid working body, such as regular water, which has a high specific heat capacity (4.18 kJ/kg • °C) and can absorb a lot of energy. Sometimes non-freezing liquid—an aqueous solution of propylene or ethylene glycol—is utilized. How does this take place?

1. Burning hydrocarbon fuel or consuming electricity, the installation heats the water to a temperature of 40 … 90 degrees.
2. Hot coolant moves through the pipes using a pump or naturally (due to convection) to water radiators.
3. The heat transfer occurs between the heating devices and the air of the rooms – the water flowing through the battery cools at 10-20 ° C, the atmosphere of the room warms up. Plus the hot surface of the radiator emits infrared heat radiation.
4. The cooled coolant returns through the highway to the heat generator, where it heats up again to the required temperature.
5. Excess water formed during thermal expansion enters a special container. When the temperature in the system drops, the liquid is compressed again and leaves the expansion tank.

Reference: At temperatures above 60 °C, there is an intense release of infrared heat from the battery surface.

One thing to keep in mind before heating is that the amount of water in the system has little to no effect on heating efficiency. This indicator only has an impact on how quickly the heat generator starts or stops heating or cooling the house.

We enumerate the following crucial attributes:

• the temperature difference at the inlet and output of the home heater, the maximum permissible – 25 degrees;
• Source power – should be selected by calculating thermal losses through the outer walls + warming up for ventilation;
• The flow rate of the coolant is the volume of water passing through the heating devices for 1 hour;
• The hydraulic resistance of the pipeline network along with the radiators, ideally, should not exceed 1 bar (10 m of water column).

In his video, Vladimir Sukhorukov, an expert, will explain the total volume of coolant in the pipes:

Types of boilers and other hot water devices

The installation that heats the working body (water) determines how efficient the heating system is in a private home. The appropriately chosen unit uses reasonably priced energy carriers to generate the necessary amount of heat for radiators and, if applicable, an indirect heating boiler.

An independent water system can function from:

• a hot water boiler using a certain fuel – natural gas, firewood, coal, diesel fuel;
• electric boiler;
• stoves on wood with a water circle (metal or brick);
• thermal pump.

Furthermore. Certain types of heaters combine two or more energy sources at the same time. Examples of these include coal and natural gas or firewood and electricity (a photo of one such heater is displayed below). Additionally, there are universal boilers that allow you to install a gas, pellet, or diesel nozzle.

The most common method of arranging gas, electric, and solid fuel heating in cottages is through boilers. The remaining heat generators are wall and stationary, with the latter made exclusively for the floor. The high cost of fuel is the reason diesel units are used less frequently. A comprehensive guide examines the process of selecting the ideal water heatership boiler.

Stove heating works well for heating garages, summer houses, and small residential homes between 50 and 100 m² when paired with contemporary radiators or water registers. One drawback is that the water is uncontrollably heated by the heat exchanger inside the stove. It’s critical to maintain forced circulation in the system to prevent boiling.

Citation. Such schemes were previously made by gravity using an open expansion tank and no pump. Steel pipes with an internal diameter of 40–80 mm were used to weld highways and registers. The pipes were laid with a gradient of 3-5 mm per meter to improve gravity. Because the system did not fear boiling, heating was referred to as steam.

The former Union’s member states lacked widespread use of thermal pumps. Reasons:

• The main problem is the high cost of equipment;
• Due to the cold climate, apparatuses of the "Air-Water" type are simply ineffective;
• Geothermal systems "Earth – Water" are complex in installation;
• Electronic blocks and compressors of heat pumps are very expensive to repair and maintenance.

Units have a payback period longer than 15 years because of their high cost. However, the installations’ efficiency (3–4 kW of heat for every kWh of electricity used) draws artisans who are looking to salvage handcrafted equivalents from abandoned air conditioners.

Water heating devices

The building’s heating components include:

• traditional radiators installed under window openings and near the cold walls, for example, on the north side of the building;
• pipe contours of floor heating, otherwise – warm floors;
• skirting heaters;
• Intra -polling convectors.

The least expensive and most dependable model on the list is the water radiator heating system. It’s possible to install and connect the batteries on your own; the key is to accurately determine the number of sections based on power. The room’s lower zone has weak heating, and the devices’ visible locations aren’t always in line with the interior decor. These are the drawbacks.

Based on the material of manufacture, all radiators that are currently for sale are categorized into four groups:

1. Aluminum – sectional and monolithic. In fact, they are cast from silumin – an aluminum alloy with silicon, are the most effective in the speed of heating.
2. Bimetallic. A complete analogue of aluminum batteries, only inside is a frame of steel pipes. The scope of use is multi -apartment high -rise houses with central heat supply, where the coolant is supplied with a pressure of more than 10 bar.
3. Steel panel. Relatively cheap monolithic radiators made of sheets of stamped metal plus additional nuting.
4. Cast iron sectional. Heavy, warm -intensive and expensive devices with original design. Due to decent weight, some models are equipped with legs-to hang such a "accordion" on the wall is unrealistic.

Note: In terms of contemporary design performance, we are discussing cast-iron radiators. MS-140 batteries, which are of the Soviet type, are obsolete in every way.

Steel devices are in high demand because they are affordable and, in terms of heat transfer, the thin metal is not all that inferior to silicon. Cast-iron, bimetallic, and aluminum heaters come next. Decide which you prefer.

The design of the warm floors

The following components make up the floor heating system:

• heating contours of metal -plastic or polyethylene pipes flooded with cement screed or laid between the lags (in a wooden house);
• Distributive collector with flow meters and thermostatic valves to regulate the flow of water in each loop;
• mixing node – circulation pump plus the valve (two- or three -way), which maintains the temperature of the coolant in the range 35 … 55 ° C.

The boiler is connected to the judge and collector knot via the feeding and reverse highways. Water that has been heated to 60 to 80 degrees is mixed into the contours using a valve as the coolant that is circulated cools down.

The most economical and comfortable way to heat a space is with warm floors, but installing them will set you back two to three times as much as a radiator network device. The picture displays the best heating option: batteries adjusted by thermal hungs plus floor water contours.

Convectors skirting and intra -floor

The layout of both types of heaters is comparable to that of a water heat exchanger, which consists of a copper coil with thin plates arranged in ribs. The floor’s heating component is enclosed by a decorative casing that resembles a baseboard from the outside, with openings left for air to flow through at the top and bottom.

The case beneath the clean floor level houses the heat exchanger for the intra-fire convector. Certain models have low-noise fans installed, which improves the heater’s efficiency. Coolant is supplied via pipes buried beneath the screed in a covert manner.

The devices that have been described are well-integrated into the room’s design, and subterranean convectors are an essential feature close to the transparent, glass-only outer walls. However, typical homeowners are not in a rush to buy these gadgets because:

• Copper-aluminum radiators of convectors-the pleasure is not cheap;
• For a full heating of the cottage located in the middle lane, you will have to put heaters around the perimeter of all rooms;
• intra -floor heat exchangers without fans are ineffective;
• The same products with fans publish a quiet monotonous rumble.

Thus, the convector is a helpful device in certain locations where it is challenging to install regular batteries. However, it is excessively costly to heat an entire building using such devices.

Radiator network – 4 methods of pipe wiring

There are four primary schemes used for setting up heating in private homes:

• one -pipe, it is also “Leningrad”;
• two -pipe shoulder (otherwise – dead end);
• two -pipe passing;
• collector.

Note: Two schemes may be combined in a two-story cottage. As an illustration, install a collector system on the first floor and mount wiring with a coolant passing course on the second. But these kinds of fixes aren’t always appropriate.

By today’s standards, every scheme on the list is made sealed. Depending on the temperature, the water in the pipes is under pressure between 0.5 and 3 bar. A closed-type expansion tank with a rubber membrane inside is installed. Forced circulation from the electric pump is a requirement for the system to function.

Because of the convective fluid course, Leningradka and a two-pipe dead end diagram can operate without a circulation pump. The idea is as follows: hotter, less specific mass water moves up against colder, more severe water. However, pipes of larger sizes (Ø32–80 mm) mounted at a specific slope are required in order to execute and create a groove.

Because collector and passing ring wiring, also known as the Tichelman loop, requires the forced pumping of water to function, it is always completed in a closed manner. Examine each plan in greater detail.

One -pine -packed connection option

At first glance, the system appears straightforward: one highway is positioned horizontally along the building’s exterior walls, to which all of the radiators are connected, along with both eyeliners. The cooled coolant returns to the common pipe after passing the first battery, combines with the hot material, and enters the subsequent heating device. As a result, the coolant used in each radiator after that gets colder.

1. The diameter of the main pipe is not less than 20 mm (internal passage), which corresponds to the outer size of the metal -plastic 26 mm, polypropylene – 32 mm. The indicated section remains the same throughout the length of the pipeline.
2. The number of batteries in 1 branch is a maximum of 6 pcs., Otherwise, you will have to build up the diameter of the diluting pipe to 32-50 mm. Installation becomes more complicated and rises by 15-20% (minimum).
3. Since less heated water comes to distant radiators, their heat exchanger surface should be increased by 10 … 30%, adding the number of sections.
4. Manual or automatic adjustment of the duct through 1 heater affects the operation of other devices, since the temperature and water consumption in the general highway changes.

Citation. In Soviet buildings, vertical single-pipe systems are used to maintain the Leningradka principle where batteries connect to risers. When organizing gear, similar schemes—albeit smaller—are employed in two-story private cottages.

For summertime and residential homes up to 60–100 m², a single-pipe closed water heating system is appropriate. There is no issue with two floors because the pump is involved and the system is split into two ring branches that converge on tees close to the boiler.

Two -pipe schemes – ring and dead end

The separation of hot and cooled coolant into supply and reverse lines distinguishes these collapses from one another. Here, two pipes connect to the batteries; first, water enters the radiators and then returns to the boiler through the second pipe. There are two systems used to heat houses:

1. With a dead end circuit, the coolant goes along the highway to the last device, then returns through the return – flows in the opposite direction.
2. In the ring loop of Tichelman, water does not change the direction of movement after leaving the battery. That is, the coolant in both highways flows in one direction.

Furthermore. One or more dead end branches, or shoulders that are either the same length or differ, make up the first system. The second is shaped like one or more closed rings coming together to form the boiler.

Benefits of connecting two pipe batteries:

• small diameters of the highways – 15-20 mm (internal);
• All radiators are filled with the coolant of the same temperature;
• There are no restrictions on the number of heaters on the 1st line;
• The system is amenable to automation and adjustment, change in consumption or a complete shutdown of one battery does not affect the work of the neighboring ones;
• Correctly collected passing wiring is well balanced hydraulically;
• low cost costs.

Building a dead end circuit by hand is simple because it is easily balanced and "forgives" careless mistakes. The Tichelman loop makes things more difficult because, in a one-story building, the double highway will undoubtedly cross the front door opening, necessitating bending it over the tops or from below under the floors.

Collector system

Here, the distribution crest near the building’s center is where the radiator connections are arranged using the radiation method. It has a two-pipe connection to the boiler, and each battery has a feed and return line of its own. Radiator eyeliners are placed under the lower floor ceiling or concealed in the floor screed to reach the devices via the quickest route.

Note: Automatic air vents mounted on the comb are used to remove air from hidden pipelines.

The modern wiring equivalent of a dead end system that maintains its dignity is called a radiation scheme. There are further benefits:

• pipes, eyeliners and a cabinet with a collector are hidden inside building structures, so the scheme is suitable for any interior solutions;
• The convenience and ease of regulation (balancing), the controls are located in one place – the distribution cabinet;
• If you equip the thermostatic valves of the combs of servo drives and put an electronic control unit, then you can fully automate the water heating of the building.

Heat-insulating shell-protected stitched polyethylene pipes with an internal diameter of 10 mm are used to connect the heaters to the collector. Depending on the number of users, a highway with a diameter of 26–40 mm is laid from the boiler room to the comb.

Negative aspects of radiation wiring

• In a living house, it is difficult to carry out pipelines to radiators – to open the screed or cut out the string;
• high cost of materials and work;
• The circuit does not work without a pump;
• The line laid inside the concrete monolith cannot be redone or replaced.
