Bypass in the heating system : benefits and features

bypass the heating system - what is it?

Wikipedia gives the following definition: Bypass - bypass line processing units, used to transport a variety of media (liquid, gas) and parallel to the shut-off control valves.

Bypass is a pipeline that bypasses (parallel) portion of the heating system.Bypass with two sides (input and output) is surrounded by cranes.Valves mounted on the pipe segment under the pump, between input and output bypass.The whole structure should be placed horizontally and can be equipped with a filter.

Bypass performs the following functions:

1. Adjusting the coolant;
2. acceleration of the process of filling and emptying a water heating system;
3. Allows repairs without stopping the flow of coolant in the system.

Install bypass and circulation pump is recommended on the highway receding.This technique allows you to create more favorable conditions for the operation of the equipment and extend their service life, as the heat transfer medium, reaching them will cool down, and thus the bypass and the pump will not come into contact with high temperatures.

Bypass in the heating system: components.Rod cranes

This type valves can be used in the heating system, but do so very rarely.This is due to the method of the overlap of the lumen, leaving a small inner diameter, which significantly reduces the rate of coolant flow and leads to additional heat losses.But these cranes have one advantage - they can be repaired by replacing worn components.

Ball Valves

The heating ball valves are used more often.Their use does not lead to additional heat loss, since they do not affect the rate of coolant flow.But the disadvantage of these valves is the inability of the repair (in case of breakage it must be replaced with new).Also, ball valves should be used regularly (Example 1-2 times a year), to the main element of this design - the ball does not "take a strong liking" to the seal.

Valves

ball valves and check valves used in bypass as a shut-off valve.

The main difference between these elements is the ability to reverse the valve to operate without human intervention.

But if we take into account the quality and service life, you should give preference to the ball valve as a check valve can quickly come into disrepair under the influence of the coolant chemical and mechanical (rust particles) impurities.

Filter and its role in the system

structure consisting of a bypass and circulation pump, it is necessary to provide a mechanical filter.It is a mesh which retains particles of debris such as scale, rust, scale, and a special tank.The filter should be periodically removed and cleaned.

Filter feature in the segment: the input valve - pump.And mounted sideways down.

Advantages Bypass: conclusions

If the system with the natural circulation has malfunctioned, you can return it to work by setting the circulation pump and the bypass.This can be done independently and without much effort.Installation of this system has such advantages:

1. High efficiency;
2. Rapid heating of premises;
3. Easy installation;
4. reliability.
