The principle of operation of the comb for a water warm floor, the connection diagram and adjustment

A water-based underfloor heating system can do wonders for keeping your house warm and comfortable. The manifold, also known as the comb, is the central control unit at the center of this system. To make sure your house stays toasty warm throughout the winter, you need to know how this comb operates, how it connects to the different parts of your heating system, and how to adjust it for best results.

What then is the precise working principle of the water warm floor comb? In essence, the hot water that circulates through the underfloor pipes is distributed through the comb. It ensures constant warmth throughout your house by distributing hot water evenly to various zones or sections of the floor after receiving it from the boiler or other heat source. Consider it as the conductor of an orchestra, guiding the distribution of warmth to the areas that require it most.

Let’s now examine the comb’s connection diagram. The comb is usually linked to the main heating circuit, which consists of the circulating pump that circulates hot water throughout the system and the boiler or heat pump. It also links to the secondary circuits, which are the separate piping loops that run beneath every area of the floor. These connections, which vary based on your home’s layout and size, are essential for guaranteeing effective heat distribution.

The real magic is in fine-tuning the comb to run at peak efficiency. The majority of contemporary combs have a variety of valves, controls, and sensors that let you adjust the water’s temperature and flow to every area of the floor. With this customization feature, you can adjust the heating output to fit different rooms in your house, such as a busy living room or a comfortable bedroom. Finding the ideal balance between energy efficiency and comfort will allow you to have a warm house without going over budget.

To sum up, the water warm floor comb is an essential component of your underfloor heating system. You can make sure that your house stays comfortably heated all year long by being aware of its operating principles, connection diagram, and adjustment procedures. For the best warmth and effectiveness, make sure to give the comb the attention it needs whether you’re installing a new system or updating an old one.

In the world of home heating and insulation, the water warm floor system is a game-changer. Essentially, it works like this: a series of pipes are installed under the floor, carrying warm water. This heat spreads evenly across the floor surface, providing cozy warmth throughout the room. Now, the magic lies in the comb for this system. Picture it as the conductor of a symphony, directing the flow of water through the pipes. Its connection diagram is like a map, guiding the water where it needs to go. And when it comes to adjustment, think of it as tuning an instrument for the perfect harmony of warmth. By tweaking settings, you can ensure each corner of your home is just the right temperature. So, whether it"s a chilly winter morning or a brisk autumn evening, your water warm floor, guided by its comb, is ready to keep you snug and comfortable.

The principle of operation of the comb warm floor

The purpose of floor heating is to provide uniform warmth throughout the rooms by means of coolant circulating through pipes embedded in the ceiling design. Why a distribution comb TP is necessary

1. 2 pipelines are coming from the heat source – supply and reverse, and there are 10 or more warming loops. The water from the boiler must be distributed according to the contours, and not evenly, but in accordance with the need for heat.
2. Floor heating is a low -temperature heating system. The coolant heats up to a maximum of 55 ° C, and the work schedule lies in the range of 35–45 ° C. Providing this mode with the help of the boiler is difficult and uneconomical. Therefore, combs for a warm floor are used that regulate the temperature of the water.

You don’t always need the comb when there is floor heating. Well-known manufacturers (like Oventrop, Herz Armaturen, and Danfoss) provide straightforward, low-cost devices with mechanical thermal controllers for 1-2 heating contours. For instance, Unibox and Unidis wall installation local installation regulators are sold under the Overtrop brand.

The following components are part of the distribution unit’s base set:

• A collector of a warm floor for 2 or more discharge with thermostatic valves and flow meters (rotameters);
• cutting reinforcement (ball valves);
• automatic air vents for each collector branch;
• taps or traffic jams for emptying;
• thermometers;
• The cabinet is metal.

The collector is where the highways carrying the boiler’s coolant join, and it’s also where the warm floor contours’ eyeliner connects. Thermostatic valves, which can be manually or automatically controlled, are in charge of each loop’s heated water consumption. Rotometers mounted on the TP supply (or reverse) collector display the consumption value.

Citation. Collectors are constructed from premium plastic, stainless steel, and brass. Technically speaking, there is no difference between them, and plastic is 15-20% less expensive than metal.

The necessary components are added to the base set based on the comb’s selected principle of operation and the technique used to modify the warm water floor’s temperature. Suitable comb sets and regulation techniques in the collection We’ll give it more thought.

Adjustment of the amount (consumption) of the coolant

This is the most straightforward and affordable method of automatically controlling the flooring’s temperature. It entails employing specialized RTL thermal heads mounted on the collector thermostats to restrict the coolant’s flow through the contours. Here, the diagram that links the warm floor’s hinges to the comb is implemented without the need for a separate circulation pump, as shown in the picture:

The ability of RTL thermal heads to focus on the temperature of the coolant’s reverse flow rather than the ambient air is the foundation for the comb’s working principle.

The necessary reverse temperature, which is typically 40 °C, is set on the head of the device. Once it is, the passage section is blocked by the thermo-sensitive element pressing on the valve rod. The floor surface stops heating when there is less coolant flowing through the contour. Parts of the hot coolant from the boiler can enter the circuit when the water in the loop drops below 40 °C, causing the thermal head to release the stem once more.

The heating contours’ length cannot be greater than 60 meters in order for the pressure of the central circulation pump to overcome the hydraulic resistance of the heating contours. If not, the surface will warm up in an uneven manner similar to a room. Such a comb is easy to assemble for a warm floor, and can be done so with your hands if you’d like. In this video, expert Vladimir Sukhorukov will provide you with more information regarding the quantitative temperature control of TP on the collector:

High -quality (temperature) regulation of TP

The idea behind this method is to combine hot water from the boiler with cooled coolant from the floor heating system. Consequently, the contours receive coolant at a specific temperature of 35 to 45 °C. The mixing unit’s components are added to the comb’s base kit:

• additional circulation pump for a warm floor;
• a two- or three -way valve mixing hot and cooled water;
• Thermal head with a remote temperature sensor;
• Safety thermostat that controls the operation of the pump.

You can purchase a ready-made mixing node with a pump and connect it to a warm floor with a comb in place of the provided set of parts. Such Danfoss nodes, intended for 9 and 13 kW of thermal power for floor heating, are depicted below the figure:

The following is the connection diagram for a warm floor comb with a thermogol and a two-way valve:

1. At the heating stage, a two -way thermostatic valve installed on the supply line is in an open position, passing the entire coolant into the floor heating system.
2. When the water temperature reaches the set value (usually 45 ° C), the liquid in the flask of the overhead temperature sensor expands and acts on thermal tanning tanks. The latter presses the rod of a 2-year thermostatic valve.
3. Due to further temperature growth in the boiler line, the valve overlaps the flow completely. The coolant circulates inside the underfloor system, encouraged by its own pump.
4. After cooling the water in the contours of 1-2 ° C, the liquid in the flask of the sensor is compressed and the valve opens, mixing a portion of hot water from the outside into the contours. So the temperature of the coolant at the exit from the comb to warm floors is maintained at a constant level.
5. The task of the invoice thermostat of security is to stop the work of floor heating in an emergency, when water with a temperature of more than 55 ° C gets into the contours. The thermostat turns off the circulation pump and the servo drive control unit (if any). The working scheme of the comb with a mixing knot is shown in the figure:

Note: When all warming contours abruptly closed due to automatic regulation and there was nowhere to pump water (work on a closed valve), the bypass valve depicted in the circuit is used to launch the coolant in a circle through the bypass.

Three -way valve diagram

An accurate and more seamless coolant temperature adjustment results in a mixing unit equipped with a 3-track valve. After that, the camshaft operates somewhat differently because mixing takes place inside the valve rather than in the supply collector. The work algorithm is the same as in the prior instance; the only difference is that regulation happens more precisely and continuously. The diagram displays the comb device with a three-way mixing valve:

The following methods are used to control the mixing node:

1. Manually. The handle on the valve is fixed in 1 position, the flows are mixed in unchanged proportions. This is a primitive and unproductive method, since the heat consumption by a floor heating system is a variable.
2. Automatically from a thermogram with a remote temperature sensor. Mixing thermal class with a pressure rod is used. With a decrease in the temperature in the reverse manifold, the heat -heading releases the valve rod and the hot coolant going from the boiler (shown above in the diagram) is mixed.

Although the suggested approach is the most expensive in terms of parts, installation, and configuration fees, it is also the most successful.

Management of heating contours

If additional automation tools are not established, the coolant’s flow rate remains unchanged with high-quality temperature regulation. Without them, the supply/reverse manifold’s valves and rotameters—which control the amount of water flowing through the circuit—must be adjusted by hand. On the other hand, thermal valves can be operated automatically and under control.

The way the system operates is as follows: each room has wired or wireless thermal controllers that are connected to a single control unit (controller) and track the temperature of the air. He uses servo drives to open and close the valves on the underfloor heating comb in response to signals from indoor thermostats. The diagram illustrates how the controller can simultaneously regulate the radiator system and floor heating in this manner:

Apart from controlling temperature in conjunction with thermostats, the controller is capable of several intriguing functions:

• respond to changes in weather conditions on the street;
• to warm up the necessary premises in advance to the given time;
• disconnect heating with warm floors in unused rooms;
• control remotely through GSM communication or Internet.

In addition to making residents feel more comfortable, the use of servo drives and automation tools lowers the cost of heating a private home by 15-20% while also saving money on energy payments.

A comb for a warm floor with your own hands

There are two ways to make the feed and reverse manifold yourself to save money, since the camshaft assembly for warm floors can be expensive:

• Collect a knot of brass or plastic tees intended for heating.
• independently solder the comb of polypropylene.

Thermostatic valves and other components must be purchased in accordance with the chosen regulation scheme in both situations. The thread is used to connect the tees, and polypropylene fittings are welded together. There are a lot of compounds; therefore, every joint needs to be made with reliability to prevent leaks in the future. When making a comb out of polypropylene, it’s important to connect the parts as soon as possible while withstanding the heating process.

The primary disadvantage of making your own warm floor combs is how hard it is to fine-tune and adjust them in the beginning without flowers. Because the heat loss in the rooms varies, the coolant flow rate will need to be randomly determined even if the pipe lengths in the contours are the same.

To maximize the performance of your water warm floor system and guarantee effective heating in your house, you must be aware of how it works. Understanding how the water warm floor comb works will help you better understand how heat is dispersed throughout your room. The comb is an essential part that controls the warm water flow via the pipes under your floor to create a comfortable atmosphere.

For a water warm floor system to be installed successfully, connection diagrams are essential. These schematics offer a visual aid by showing how each part joins together to create a working heating network. When pipes are connected correctly, water flows through them smoothly, distributing heat evenly across the floor. It is essential to carefully follow the diagram during installation to prevent issues and get the best possible performance.

The last stage in optimizing the comfort and effectiveness of your water warm floor system is adjustment. You can adjust the heating to fit your preferences and the unique requirements of each room by adjusting variables like the water temperature and flow rate. With this customization, you can minimize energy use and maintain a comfortable indoor climate, which will ultimately save you money and resources.

To sum up, knowing how the comb works, carefully observing connection diagrams, and making the required modifications are essential to maximizing the efficiency of a water warm floor system in your house. You can guarantee effective heating, improve comfort, and make a positive impact on a more sustainable living environment by becoming proficient with these components.
