You can make sure that your underfloor heating system operates effectively and gives you warmth and comfort during the colder months by arming yourself with the appropriate information and equipment.

Application area

Although floor warm systems are becoming more and more common in residential buildings, proper heating cannot be provided without a control valve. Three-salary crane: a device that modifies the water floor’s heating intensity. The water floor is covered in screed.

The valve is positioned as an independent device as well as in conjunction with a mixing-distribution node. Installing a multifunctional manifold in a small room (kitchen, bathroom, or toilet) is not worth the expense.

For such rooms, regulate the liquid’s volume and the temperature regime for a three-year-old thermosmes.

The primary usage areas are:

1. In the radiator heating system.
2. In the DHW system.
3. In warm floors.

Functions

The way that water heats floors differs greatly from battery-operated standard heating. The temperature of the water required for the sexual pipeline, which is located in the cement screed, must be significantly lower than that of radiator circulators. As a result, a three-seat running unit must be set up, in which the coolant will be raised to the appropriate level.

The primary purpose is to heat a liquid to a temperature that satisfies warm floor standards, which are between +35 and +55 degrees.

Device and principle of operation

The butt valve, which has three holes—two input and one output—is a tool for blending and controlling water flows. The heat-sensitive damper, which is positioned in the space between the input holes, controls how the heated and cooled liquid moves. These days’ gadgets come with control valves or thermograms.

The floor valve that controls heating operates continuously. The methodical procedure appears like this:

• Heated water is supplied to the first entrance – its temperature is determined in the valve;
• If the degree of water heating exceeds the required for warm floors, then the outlet of the cooled liquid from the return through the second hole opens;
• Inside the valve, a heated liquid with chilled;
• after receiving the desired temperature, the return is overlapped;
• The coolant through the output is supplied to the pipes of the warm floor.

Constant pressure in the highway is necessary for the thermal class to function properly.

If there is a thermal tank present, the liquid heats up in 15 minutes.When using an automatic tap that has a servo, heating takes place in 3 minutes.

Kinds

Automatic

The sensor can regulate the electric or thermal drive in an automatic crane.

Mixing node types:

• Simple – if the temperature rises, the liquid expands, the shutters are opened, cold and hot water are mixed.
• Three -bed valves with a thermostat with a remote thermostat for warm floors – more improved models. They are widespread, as they are accurate, and electricity is not required for their work. Average price from 500 rubles to 2500 r.

• Three -track valves for heating with a thermostat – they regulate the flows of heated and chilled water, as well as temperature control is carried out by a built -in thermostat. The expansion and narrowing of the holes occurs automatically, depending on the temperature of the liquid.

• With an electric drive (a drive with a magnet or a servo drive) – the damper in the valve is triggered under the influence of the electric motor, it is controlled by the controller, a signal from a thermal attempt arrives at it. They are simply connected, so they are widely used. But unreliability, their main drawback, as they depend on electricity. Their cost is higher than with a thermal tower, approximately 4 – 5 thousand rubles.

• With pneumo or hydraulic drive – are used more often in production, for devices with high pressure. Have a high cost, but their service life is longer.
• Electronic – adjustment is carried out by a built -in electric motor or a control element with a thermometer.

Materials of manufacture

The components of three-legged type T-lamb valves are as follows:

1. Brass – copper alloy with zinc additives. The product is not subjected to corrosion destruction, it is strong, durable. Sometimes these thermos mixers have a chrome or nickel coating, it protects against darkening. This option is most often used in a living room.
2. Bronze – copper alloy with tin additives. It is rare, although quality is no worse than a brass.
3. Stainless steel – excellent metal for the manufacture of regulatory products. Differs in durability, strength, resistance to corrosion. But the cost of devices from it is high, so they are not suitable for a private house.

Although carbon steel titanium regulators are available, industrial use is advised. Low strength is a drawback of silaumin valves, which are made of an aluminum alloy with silicon.

Life time

Advantages and disadvantages

Three-legged thermostatic mixing valves have a straightforward design, but they are also dependable and long-lasting. Their application enables precise and high-quality control over the heating level.

The devices are small and sealed. Additionally, keep the pipes and screed from overheating to prolong the system’s lifespan.

Although there are unquestionable advantages to crane adjustments, there are also a number of drawbacks:

1. Increase hydraulic resistance – this negatively affects the functioning of the node having more than one collector.
2. There is a risk of a large volume of hot coolant into the floor pipes. And this can lead to a leak and bullying of the system. Such problems more often arise at the time of starting the device.

Manufacturers

It is imperative to prioritize mixing valves sourced from manufacturers with a strong track record in the industry. These businesses consist of:

1. ESBE (Sweden) – occupies a leading position on the quality of products of this type. The valves are reliable, with a warranty period of more than 5 years.
2. Valtec -The Russian-Italian company, its mixing cranes have good characteristics at an affordable price. Warranty – 7 years.
3. Honeywell (America) – the priority of the mixers of this company is a convenient and simple installation. They are reliable, but expensive.

But it’s important to keep in mind that even top-notch products won’t allow the system to operate correctly if they’re installed incorrectly.

How to choose the right?

Choosing a three-way valve from specialty stores is advised. After selecting a model, you must expand upon its features. When purchasing a gadget, you require:

• study all the documentation – warranty, manufacturer certificate, installation and operation instructions;
• give preference to bronze or brass instruments – they will not expand when heated;
• Publish from the capacity of the valve – this parameter must correspond to the productivity of the boiler;
• Pick up a valve with a cross section, which exactly coincides with the size of the floor pipes, with a mismatch you will have to buy adapters.

It’s crucial to remember that the apparent coincidence between the valve’s input and output diameters does not indicate anything about its bandwidth. The size of the holes’ internal section has an impact on this. The documents that go with it specify this parameter.

The size of the heated room must be taken into consideration when selecting a device; for large spaces, an automatic device is advised as it can maintain the right temperature. It doesn’t make sense to overpay for a more complex model because he will function well in small rooms that are sufficiently simple to use a thermogram.

It’s important to visually check the item for chips and cracks before purchasing. The interior of the gadget should be golden if it is made of brass.

Investing in automated equipment will make the adjustment process easier. Additionally, software that is readily available will configure the temperature while accounting for the day and time of the week.

In the realm of home heating, a three-way valve plays a crucial role in ensuring efficient warmth distribution, especially for underfloor heating systems. This valve has become a go-to solution for homeowners aiming to optimize their heating while minimizing energy costs. Understanding its types, such as mixing and diverting valves, is essential for selecting the right fit for your system. Additionally, familiarizing yourself with connection diagrams simplifies the installation process, making it less daunting. Proper installation not only ensures the valve"s longevity but also guarantees that your warm floor operates at its peak performance, offering you cozy comfort throughout the chilly months. Whether you"re retrofitting an existing system or planning a new installation, grasping the basics of a three-way valve can make a world of difference in achieving a snug and energy-efficient home.

Using the scheme where the valve is a component of the distribution unit is necessary if the area is large.

It will guarantee that the sexual heating device runs continuously and that the water entering the floor has the appropriate volume and temperature.

Here is the connection diagram:

• The pump is installed on the supply pipe, it will pump heated coolant from the source;
• Then the temperature sensor is installed, it will control the degree of heating;
• At the next stage, a three -way valve is attached – it mixes the coolant to a given degree;
• A crane is placed on the reverse circuit, through which chilled water will enter the three -way device.

In other words, the floor pipes below will receive the heat carrier that has been heated to the necessary temperature.

Connection diagrams depending on the design

Furthermore, there are differences in the design and direction of the device’s coolant between the connection diagrams:

1. L-shaped – the product is equipped with two holes with the side and one round below of the case. The heated liquid is supplied to the side entrance, and the cooled into the lower. After mixing, water moves into the floor branches through another side hole.
2. T-shaped – both streams, cold and hot, fall into the mixer through the side entrances. Mixed coolant is sent to the floor along the central lower output.

When planning a three-position valve installation, it’s important to consider how the valve will fit into the highway’s binding.

Installation and connection of a three -way valve to a warm floor

Attaching a three-way valve to a heated floor is a simple task that can be completed with your hands. The most important thing is to follow the instructions in the attachment.

The letters stand for all inputs and outputs:

• A – entrance for heated coolant;
• C – input hole for chilled water;
• Ab – output.

Keep in mind that disassembling the device might be necessary before connecting it, so you should be able to get as close to the node as possible.

Materials and tools

You must gather the required tools before installing the valve. It will be necessary to have two wrenches, pliers, ri-type gaskets, and tape FUM.

The course of work

This is how the work appears:

1. The fittings are cleaned from the ends of the pipes from pollution and burrs.
2. The same procedure is done with valve nozzles.
3. Checking for gaskets in the nut is carried out.
4. Then the nuts are wound on the nozzles and delayed – but not much. Two keys participate in this procedure – one to twist the nut, the second to hold the valve.
5. A mechanical filter is installed in front of the valve.

It is important to check that the valve outputs are connected correctly to the following: a for hot water, b for a bypass from the return, and AB collector for floor taps.

Winding up a plumbing or fum tape is advised to guarantee the tightness of joints.

System check

It needs to be checked in the work in addition to the mixing tap being installed correctly. A heated coolant that has reached 25 degrees is used to test the system. A day is the crimping time.

You can fill the screed after you’ve checked.

Common installation errors

The most frequent mistake made when installing a three-way valve is to connect the feed and return floor’s contours incorrectly. For instance, when the input hole is connected to the floor circuit pipes.

Consequently, one must pay close attention, as indicated by the letter designations at the mixer’s outputs. Hole confusion prevents the device from working.

In order to comply with the manufacturer’s instructions regarding the spacing between straight sections prior to and following the screw, it is also essential to precisely follow those instructions. The regulator’s ability to function will be compromised in the event that this rule is broken.
