Pumps for home heating

Types of pumps for heating systems

For space heating systems primarily use pumps with a "wet" or "dry" rotor.

Design "wet" circulating pump is quite simple: the impeller is in the fluid that is pumped pump.In this case, the fluid performs functions in addition to the heat transfer function and the motor cooling lubricates the pump parts.

The main characteristic of this design - the ability to displace air during start-up.The disadvantage of "wet" pump is efficiency, which does not exceed 50%.Such a circulation pump is installed in small, one-story residential buildings.

Types of pumps for heating systems

type pump "dry" rotor is mainly installed in multi-storey buildings, asit is designed to pump water in large quantities.The motor of this design is not in contact with the pumped water and installed directly into the pipeline.

Types of pumps for heating systems

The above characteristics will help you to choose a practical pump installation for your home.

Selection of pump for heating

In the selection and immediately prior to the installation of the circulating pump, bought him a man must make the appropriate calculations, and this is best done by a specialist.

The most important thing you need to know - is the amount of heat required for heating your home.To answer this question, consider the following:

  • How insulated floors and walls of the room;What
  • windows installed in the house and so on.

Recently went on sale adjustable pumps with built-in time switch and pressure control.These pumps are particularly suitable for dismantling or repairing an existing heating system, becausethey are perfectly adapted to the changes in the system.They also allow you to save power consumption.This pump system is designed to operate from DC at a voltage of 12-24 volts.

important factor in the selection of the pump is the material from which it is made.It is of paramount importance.If you pick up the pump for heating floors, it is best to take the pump casing which is made of stainless steel.This will prolong the life of the pump design, asthis material is more resistant to corrosion, in contrast, for example, iron.The great advantage presented at today's pump market is that the bearings and the shaft is made from a durable material - ceramics.

Installation circulator

Note that before installing the circulator, experts recommend installing a special booster tappet (tank), which is set to support the static pressure in the pipes.

The next step is to remove the excess air from the pipeline system.This is done as follows: the system is filled with water, is removed via the air valves for radiators.Then include boiler and pump.Next, open the radiator valve and allow the pump to run for a few minutes.After the pump is turned off again and removed from the air system.Then, if necessary, supplement the water system and make the reconnection.

Modern circulating pumps are easy to install and do not require special settings.There are two main installation circuit circulation pumps: two-pipe and one-pipe.

According to the diagram below to connect the installation produce functional chain from the valve and the pump.

In addition to all the above advantages of the circulation pumps, there is another - a democratic and reasonable price that will please any owner!
