Today, many homeowners prefer the systems of domestic heating, which played a leading role with warm water sexes. Using heat a heat transfer fluid, it is possible to achieve high-quality performance in the heating housing. The very design of the heating system is already at first glance gives every reason to believe this way of heating efficient. The operating principle of water sexes is fundamentally different from the traditional methods of heating. In this situation, the functionality of each important element, and device included in a single set of equipment.
Quality work of the heating system depends on how well-coolant flow rate in the pipelines of water sexes. With this task cope underfloor heating collectorsWhich together with flowmeter provide a rational distribution of boiler water in heating circuits. What is the process a bunch of "collector - meter", the importance of its functions, and how does it work? We will try to learn more details of these and many other issues.
Underfloor heating and a place which occupies a manifold with flowmeter
The peculiarity of both underfloor heating systems lies in the fact that the heated heat transfer fluid, moving along the heating circuit, transmits some of the thermal energy of the floor surface. Thus, due to the floor heating heat is transferred air mass circulating inside the building, in the upward direction. Feeding warm water in the heating circuits, the intensity and flow deals with a range of devices including:
- three-way valve;
- circulation pump;
- collector.
Control over the distribution of the coolant provides a flow meter for floor heating. This device plays a key role in the work of the entire pumping and mixing group. Collector for underfloor heating designed to supply hot water and collecting coolant exhaust for further use in a pipeline system of the heating system. The pump-mixing unit mixes the hot water flowing from the heat source, with coolant returned to the loop - the return line. On this principle of action is based functionality and efficiency of the heating floors.
Along with work safety valves, flowmeters are designed for adjustment of the coolant temperature in the water circuits of individual floor. With these devices provide the necessary volume of treated water supplied to the warm water system of the floor. In other words, the track number of the equipment in the water coolant heat conductor, hence, functionality of the entire heating system.
The functionality of the meter
Flowmeter or, if you give a complete definition of this node, float flowmeter, at first glance, the usual mechanical device. The basis of the product design includes a plastic body (there are models of brass), within which is placed a float polypropylene. The housing is equipped with a transparent bulb in which scale marking is applied. Movement of the float up and down inside the device indicates a specific value on the scale at which it is possible to judge the volume of the coolant circulating in the piping system - whether it is sufficient to complete the work of heating contours.
From the point of view of the theory, the heating system can work without this device. In this case, the need to manually adjust the volume of the water entering the loop, based on personal feelings when you change the room temperature.
On a note: the sound of running pump and underfloor heating intensity can judge the degree of usefulness of the coolant supply hot heating circuits.
Refuse flowmeter use in underfloor apparatus is fraught with the following problems:
- separate water circuits are supplied with coolant floor excluding singularities premises, whereby the value of the floor surface temperature of the heated rooms will vary;
- consumption of energy used for heating devices (electricity or gas) is increased.
For example, you plan to heat both the bathroom and the children's room. Autonomous gas boiler to heat the water bath and child alike, in a temperature regime. However, the bathroom smaller in size, and it will require less heating boiler water, than to supply the underfloor heating in the nursery. To achieve an optimal coolant supply underfloor heating in every room, you can use the meter. Consequently, due to the operation of this device will be able to get in the bathroom and children's room for individual comfort temperature values.
Commending the work of the device and the principle of action can draw the following conclusions:
- the device operates completely autonomously, without requiring additional power source;
- meter working principle allows you to create the optimum coolant flow for heating circuits, significantly reducing the energy consumption of heating devices;
- instrument design provides visual control over the amount of water in the pipeline;
- manifold with flow meters for underfloor heating facilitates control over the operation of the whole system is easy to install and undemanding maintenance.
Important! Mounting is carried out strictly in a vertical position, simply screwing the device in a special slot collector. Fixed unit with the union nut.
On a note: mounting a floor heating, try to get the same heat lines The length of all the water circuits - despite possible differences in the configuration, it greatly simplifies the adjustment of the entire heating system and allows for optimal temperature parameters.
The principle of operation of the flowmeter. Installation and setup
When installing and connecting the collector circuits of underfloor heating meter is placed on the collecting comb, into which waste water flows. When the coolant temperature reaches a predetermined value, in the reverse of the reservoir valve is triggered, narrowing or completely blocking the lumen for receipt of water. System to work on this scheme, pumping and mixing unit and manifold equipped with thermostats.
To the water level in a transparent flask coincide with divisions in the horizontal scale, the instrument must occupy a vertical position. Therefore, for normal operation controlling group header should be set using plumb bob or spirit level, ensuring a strictly horizontal components equipment. Installing a collector with disabilities can cause improper operation of heating equipment.
Important! Finishing facilities, the installation of the collector enclosure may damage the individual mixing element group, so the heating units and devices must be arranged compact.
Installation and adjustment devices is performed in accordance with instructions for installation and operation, generally in the following sequence:
- using the key screw flowmeter in technological hole modular manifold portion;
- rotating flask meter counterclockwise, prepare the instrument for operation;
- dismantle the plant protector (usually in the form of a ring);
- set desired pressure by turning clockwise brass ring in the housing to the desired point - will place the float arrangement adapted to demonstrate the alignment;
- to prevent mechanical damage to the device to close the ring of special brass plate;
- check the operation of the device as part of the whole heating system.
Finally
During operation of the water floor heating bulb meter at the collector should be available visual inspection and, if necessary, maintenance.
Each water circuit connected to the collector, equipped with an individual flow meter.
On the heating quality and functionality of the system water sexes device selection models are not particularly affected - subject to the rules installation and operation of underfloor heating equipment can achieve the necessary indicators installing any equipment quality performance.
