Heating

One of the most important aspects in the process of heating design is the installation process, which directly affects the performance of the equipment. But many owners of apartments and country houses do not always correctly carry out this process, which leads to constant repair. In this article we will consider only the correct connection of the radiator to the heating systems.

Instrument connection options

Perhaps, it’s worth starting with the ways of laying heating pipelines, which is why the connection pattern of the radiator directly depends on the heating.

There are two ways of laying pipelines for heating:

Monotube - wherein the coolant is fed through a pipe to the radiators of heating, fixed successively one after the other and, having washed them, returns to the source of heating. As a rule, at 20-30% of the length of the route is already considerably cooled coolant.
Twin tube - consisting of two independent pipes: the supply and return, and in this case, the coolant involves a parallel connection of heating elements.

Modern battery designs are mostly equipped with four possible pipeline installation points (two upper and two lower). Therefore, connecting radiators to various systems is possible in several ways.

Very convenient, if you live in your home, when designing to hide pipes under the floor covering - you will get a small section of the “warm floor” system

One way connection

The most common way to install a heating system can be called a one-sided option when it comes to apartment buildings.

This scheme of connecting a heating radiator provides for the connection of pipelines on one side of the device:

The supply pipe is usually connected to the nozzle at the top.
Reverse is fixed at the bottom position.

The photo shows a version with one-sided arrangement of pipes.

Note! With one-sided connection of the radiator with the change of the places of the supply and return circuits, the loss of heat transfer of the system up to 7% is possible.

The one-sided layout of the battery pipeline necessarily includes a jumper connecting the “flow” and “return flow” in front of the device. Dismantling this jumper with your own hands is extremely undesirable, since it can disrupt the operation of the entire central heating system.

The heat transfer coefficient can also reduce the unjustified increase in sections of the device, more than 12-15 pieces due to the weakening of the heating of the remote area.

Diagonal connection

For products with the number of sections exceeding 15 pieces, the diagonal connection scheme of steel radiators will be the most optimal.

According to this scheme:

The supply pipeline is mounted to the device at the top, on the one hand.
Diverting at the lowest point, on the other hand.

The coolant, being distributed from the top down and diagonally, ensures uniform heating of all parts of the radiator. Violation of the principle of supply and return connection may entail a decrease in heating power from heating products by 40-50%.

A diagonal connection may not seem the most attractive, but for many homes this solution is the most optimal.

Note! For maximum effect, a diagonal connection is used in two-pipe heating systems.

If the calculations were incorrect, then there is a high probability that near the end of the movement of fuel it will lose half of its heat

Bottom connection

An acceptable scheme for connecting radiators in a private house is the lower arrangement of pipes. The process consists in connecting pipelines from different sides of the device at its lowest points. Possible loss of battery power in such a connection scheme of 12-14% can be adjusted by installing air valves through which air is removed from the system.

It will also help to increase the efficiency of heating with lower radiators - the installation of a circulating pump heating.

Tip! It is recommended to install shut-off valves in the places where the devices are connected to pipelines. This will allow to carry out repair work or dismantle and replace the failed battery without shutting down the entire heating system.

The nuances of installing and connecting radiators

Regardless of what the fixing scheme was chosen pipes with batteries, there are a number of rules for the installation of devices, by adhering to which you can create an effective heating system.

The installation instructions for radiators recommend the following:

Batteries should be installed directly under window openings, or near door openings (in private homes) - since these parts are the main sources of heat loss.
When installing the battery, it is necessary to adhere to the normative distances from the device to the appropriate structures:

At a height of about 100-120 mm from the floor.
The distance from the wall is 20-50 mm.
Below the window sill 100 mm.

The window sill should not overhang over the battery, otherwise there may be a loss of instrument power up to 4-5%.

If the heater is placed in a niche on the wall, the additional loss of heat transfer efficiency will be about 7%.

Maximum power loss occurs when trying to decorate the device:

About 10% with partial shielding.

Up to 20% with full screen closure.

We advise you to listen to the recommendations of experts, because the cost of oversight in installation and connection - reducing the efficiency and cost of heating your home.

Conclusion

We hope that the above information will help you understand and install the heating system devices correctly and without any problems. After all, if everything is done properly, then you can not spend money for many years and not think about the upcoming repairs, costs and time, which is better to spend on your family and rest.
