Calculator for calculating the performance of the circulation pump

Cottages and private houses often are not connected to the centralized heating. That is why the owners themselves set different boilers and ovenBy which heat and accommodations. But little to properly mount heating system. It is also necessary, and select pumpWhich will cause the coolant to circulate through the pipes. After all of the circulation pump depends on the characteristics of efficiency of the system and its rapid heating. How can calculate the required performance? This will help an online calculator for calculating the performance of the circulation pump.

How to use online calculator

Use of the proposed program is quite simple. The first thing to do - is to specify the capacity of the boiler. This information can be found in its technical documentation and on the rating plate of the housing. After that indicates the type of heating devices, which are installed on the premises. It can be heating radiators, convectors Flush mounting or water warm floor. And finally, it remains only to press the button "calculate the required minimum pump capacity." That's all. The result will be indicated in m3/ H, as well as in l / min.

Some explanation of the calculations

All calculations are made by the online calculator, based on the following formula:

G = W / (Δt × Kτ)where

  • G- productivity, expressed in kilograms per hour;
  • W- estimated power boiler;
  • Δt - temperature difference in the supply and return pipes, i.e. essentially the amount of heat that is taken heat exchange devices (radiators, convectors etc.);
  • KÏ„ - coefficient taking into account the specific heat coolant.

If all the power is clear, then the other parameters needed clarification. For example the temperature difference in the average equal to 20 ° C for radiators, 15 ° C for convectors and 10 ° C for underfloor heating.

KÏ„ - coefficient taking into account the heat capacity of the coolant - if the draw water, it will be equal to 1.16.

The difficulty is that the calculations are obtained independent unit, which is not very convenient. That is why the online calculator and translates it into the m3/ч.

But having made the pump performance calculations can go to computing necessary pressure.
