You will need
- 1. Circulation pump,
- 2. apparatus for welding pipes
- 3. shut-off valves,
- 4. electric cord,
- 5. plug.
Install the circulation pump is recommended with a horizontal shaft. If you are installing a pump with a vertical shaft (i.e., motor up) possible accumulation in the air, which will prevent lubrication. Installation of the pump can be made on the return pipe and the feed pipe is heating the house. Except during installation possible mechanical tension!
Pick a place where you will install the pump. You need to choose it given the fact that in the future access to the pump was not difficult. Install the pump after all the work on the system, so installing it should be the final step in the installation of the heating system. If heating is used, it should be thoroughly washed.
Cut off the pipe where you plan to install the pump, and weld to the connection for valves. Before the circulating pump and after it it is necessary to install isolation valves – this is for convenience in removing the pump for cleaning or repair. Consider also the removal of air, if you want the pump to work long and reliably.
Weld the pump in the following sequence: shut – off valves- pump – shut-off valves. During installation observe the flow direction of the water or other coolant, as well as directional arrows on the pump casing. After finishing the welding work, check the tightness of the seams and fill the heating system coolant.
Connect the power cord to the pump. The electrical connection of the pump should be made with consideration of all applicable technical rules and regulations. The minimum distance of the electrical cable between the axes of the contacts must be 3 mm, and the cross-section not less than 0.75 sq. mm Cable shall be provided with a switch or plug. Turn on the cable in the socket.
Advice 2: How to connect the indirect heating boiler
Before you connect the indirect heating boiler, make sure that the volume you had selected correctly. So one person is done the rate of 40 liters. If your family consists of 4 people, you need to install a boiler of indirect heating volume of 160 liters.
You will need
- - screwdriver;
- - gas key;
- - FUM tape;
- - gas key;
- - electric drill;
- plastic chopiki;
- - screws 100-150 mm.
Install boiler indirect heating to the wall in the same room where the Central heating boiler. Ideally, a boiler can be two feet from the boiler.
Most of all boilers in this category have five outputs for different connections. Starting from the bottom, plug in the boiler indirect heating pipe with the cold water pre-installing check valve.
To the second hole, connect the supply to the heating system, and the third is his return. By the fourth hole, connect the channel of recirculation of hot water, which set the circulating pump of low power. This will allow even to the most distant points of demand to receive hot water from the tap immediately after their discovery.
To the fifth, the top hole, connect the channel of hot water. Be sure to install a hot water accumulator (its volume is calculated according to the volume of the boilerand indirect heating) and a security group.
Temperature sensor the boilerand connect with a circular pump, the feed from the boiler coolant. Produce earthing the boilerand indirect heating, to avoid short circuits.
Picking up the indirect heating boiler, be sure to consider the capacity of the heat exchanger of the boiler, as if the power of a boiler is greater than that of the boiler, then you risk to remain without heating. The capacity of the heat exchanger of the boiler should be adequate pump capacity.
With the installation of wall-mounted boiler of indirect heating secure him so that his bottom was higher than the top point of the boiler and radiator. If you do not allows the layout of the room, try to approximate its location to the ideal, since the lower it is, the slower will heat up the water in it. If you decided to install indirect heating boiler, please note that the temperature of its lower part is equal to the return temperature of the heating system.
Advice 3: Where to put the pump in the heating
A circulation pump is installed in the heating system of private homes in order that heat is evenly distributed in all pipes and registers. The device not only helps to equalize the temperature in the heating system, but to eliminate the air tube.
Pick up in store the circulation pump of necessary capacity depending on the area of heated space and the material from which made the pipe. The most easy-to-install device with a "wet rotor", the installation of which is directly on the pipe. In order to extend its lifetime, purchase the optional filter.Determine the location of the tie-in pumpand heating system. It is recommended to install it on the return pipe (return line) in front of the boiler. Make the bypass, the so-called "bypass". Its diameter must be smaller than the diameter of the main pipe. Install the pump on the bypass so that its shaft is in the horizontal position. Position the module of the device when installing the terminals up. Mount on both sides of the pumpand ball valves. It is necessary to simplify removal and repair if necessary. At the top of bypass install automatic or manual air valve. It is required to remove the accumulated air in the system. Embed the filter into the system, placing it before the pumpohms. It will help to prevent the ingress into the device mechanical particles in the water.If the heating system uses a diaphragm tank, mount the circulation pump you need in the return line, as close as possible to the expansion tank. If necessary, it can be installed on the feed pipe, in this case cutting vertical check valve. After finishing the plumbing work, connect the device to the mains. Pour the water into the heating pipe, open the valve and return the system to flush until the tap not going in the water without mechanical impurities particle.Before starting the pumpand with manual adjustment rotational speed must razvodit. To do this, open a valve to release air, then turn the device on, wait five to ten minutes and then off again responderte it. This must be done every time when starting it up.
