Advantages and disadvantages of systems with circulation pump for heating

  1. high efficiency.Applications pump increases this figure as much as possible.
  2. Rapid heating of premises.Since water quickly getting on the system, do not need to wait a long time until the heat reaches the remote rooms, as is the case in natural circulation systems.
  3. Easy installation system.As the water moves through the pipeline under the action of the pump, then the installation does not need to follow the slopes and take care that there are no sharp turns and unnecessary obstacles.
  4. reliability.The application of modern pump will ensure the safety and reliability of the entire system.

Disadvantages

  1. dependence on electricity.
  2. fee for electricity.The pump consumes power and this entails additional permanent expenditure.
  3. high cost of equipment.

Selection of pump for heating

Selection of a pump for heating

When choosing guided by the circulating pump capacity of the heat required for heating.Calculate this figure can special organization or it can be done independently.The calculations are carried out according to formulas, but you can simplify the process and take advantage of typical projects.

In European countries, calculation is performed at the rate of 1 100 watts per square meter house, if it is 1-2 apartments, and 70 watts, if an apartment building.If damp indoor conditions, the rate was reduced to 30-50 watts.

In the CIS countries, according to the SNIP 2.04.07-86 *, should adhere to these indicators:

  1. for buildings less than 3 floors - 173 watts per square meter at temperatures down to -25 ° C and 177 watts per square meter at-30 ° C.
  2. For buildings with more than with 3 floors - 97 and 101 watts per square meter, respectively.

Installation pump: manual

Installing the pump : manual

Place the pump in the heating system can be their own hands.You will need: screw connections "American", bypass line, check valve, filter and tool kit.

sequence of instructions for installing the pump:

  1. Select the pump with suitable characteristics;
  2. circulation pump is mounted on the discharge line to the boiler;
  3. Before installing the boiler is switched off and cut off the shut-off valves;
  4. Set the pump on threaded connections (to the device at work to publish less noise, it is mounted horizontally);
  5. Mount filter and non-return valve;
  6. Set the cut-off valve in the case of repair (cuts off the device from the coolant).

Installing the pump : manual

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

Conclusions

conclusions
Installing the circulation pump in the system is appropriate, since such a system would be more advantages than disadvantages.If we make an autonomous power supply, the heating system with forced circulation of the shortcomings can be minimized.
