Installation of Taco pumps and commissioning

In any case, whatever the Taco pump was not selected, the installation must adjust its operating point in all possible modes. When commissioning should be supplied to measure flow rate (determined by the speed of filling any container of known volume, such as barrels), produced by pressure (as indicated by pressure gauge on the top), and consumed with the current (measured current outputs with forceps).

These characteristics are reconciled with passport data Taco 006 pump in the catalog. By exceeding the operating parameters (typically some reserve capacity for example, provides for installation of filters) should cover the heating Taco Mixing valve at the outlet from the well, to create additional local resistance, sufficient to establish the correct operating point - mid-performance Q (H).

Electric water heaters. Features of the national economy.

Consider the work of electric water heaters from the standpoint of physics. In the first phase electric power is converted into heat, here efficiency depends mainly on the material of the radiant heating element (from the loss of electricity in it and from the heat). In the second stage heat is transferred from element to water (efficiency depends on the area of contact with the water element). At each stage, some of the lost energy. Depending on the type of device, the efficiency is in the range 0,9-1,0. The magnitude of the Tankless water heater efficiency is close to the similar figure of perpetual motion, ie to 1, but, unfortunately, the loss still exists.

In more simple models of Electrolux SL series there half-power mode, in which odderzhivaetsya low temperature of 55 ° C. To do this in the Tankless water heater installed two radiant heating elements on the 0,8 or 0,9 kW, pressing on the front panel of EVN, you can turn on the economy. These models of water heaters quite expensive.

There are general guidelines for the selection and mode of operation of any EVN. Do not choose too small storage water heaters. With long-term mode of operation is better to use higher-capacity unit, but at 60 ° C than at 85 ° C. Temperature 60 ° C guarantees:

* Gentle treatment for the reservoir and pipelines by using water saturated with chemicals causing corrosion;
* Less fouling, which destroys the protective layer inside the tank;
* Reduction of energy consumption to maintain the temperature of hot water.

The system is free from the air - it is reality. Hydraulic Spirovent Spirovent Air Superior has been designed specifically for effective de-aeration piping systems of tall buildings:
* For the central heating system with a static height of 15 m between the boiler and the highest point;
* For cooling systems with a static height of more than 5 m between the chiller and the highest point

New hydraulic Spirovent can be used in virtually any environment. Due to a significant volume of deaeration he quickly releases the system from the air for a considerable period of time. The principle of its action is that part of the water in its tank is exposed to low blood pressure. Through this dissolved air and gases are removed from the water and the output from the vent. In conclusion, subjected to degassing of the water is TACO pumped back into the system, where it again absorbs air bubbles and are available in water gas.
Benefits for professionals in the field of heating and users

# Deaerated water
# Safe and intact system
# Lifetime of the system
# Optimal heat transfer components of the system
# No noise
# Easy installation and operation

Accumulator for individual water supply systems

Outwardly, hydraulic accumulators are very similar to flanged expansion tanks like Extrol 15 or Extrol 30 of radiant heating systems. However, the appointment and service conditions have other, hence there is a positive difference.
First, the mode accumulator over loaded. In normal operation, its frequency response is from 5 to 15 times per hour with a well chosen volume accumulator. If the volume is chosen correctly, this value can increase up to 20-30 times per hour. Of course such an operation requires a reliable, flexible membrane which can withstand a large number of loads.
Secondly, hydraulic accumulators are used in household water supply systems, so the material must not be toxic and permitted for use with drinking water.
Thirdly, the water in the water supply system in most cases comes from a well or wells. It is saturated with oxygen, which is released and accumulates in the membrane. Therefore, large accumulators at the top of the diaphragm is pipe and valve for venting the air. The appearance of such accumulator presented earlier in Figure 5.
Fourth, hydraulic accumulators usually placed on the line of cold water in the water supply system, so in terms of the temperature at which they operate, the regime more sparing. Typically, the water temperature in the system can not exceed 30 ° C.
As expansion tanks of heating systems, hydraulic accumulators are filled with water is not completely. The volume of "issue" with the work accumulator water is less than the net volume expansion tank heating system.

The radiant heating system "warm floor"

One of the most common today is radiant floor heating. Most consumers find water "warm floor". As the coolant can be used and frost free agent, but the heat will still be water.
Let's look at one of the most common water floor heating systems, which is popularly called Stalinkas. It is a structure consisting of two-pipe routing and having an upper filling. Most often these systems are found in low-rise buildings Stalinist.
The main advantage of this system is its reliability. In addition, it requires in relation to a no maintenance. Ways to create Stalinkas only two:

* According to a parallel scheme
* According to the vector diagram
In the first case, the location of the heating system was determined by type of location of bottling. The system, made by a vector diagram, more often called - with a fair movement of coolant. Among other schemes, it is the most reliable. In addition, her work is characterized by constant uniform.
So, as mentioned above, the main advantage of this system is the uniformity of its heating radiators. That is, you do not have to wait until the required space heats up, going from room to room.
But despite this advantage in our days, the system is mainly used only in country houses. This is explained by the fact that her work is not possible at elevations above the fifth floor. This significantly limits the ability of the Stalinist heating system, but at the same time, does not make it less effective.
Order heating private houses can be in our company.
