The two-pipe heating system of the house has the only drawback to the single-pipe system - it is a double amount of materials. As for the user parameters for heating a two-story house, the advantage is obvious.
Advantages of a two-pipe heating system
In a private house, it is quite possible to equip a single-pipe system, however, all rooms will be heated unevenly. In the last radiator along the coolant, water is suitable after it has warmed all the previous ones. Whatever way the heating main is laid: top or bottom, the water temperature in different batteries will be very different.
Two-pipe heating of a private house frees owners from thinking about the temperature of the batteries. You can lay pipes by the radiation method or horizontal. In any case, the water temperature does not differ in all radiators of the house. If desired, the owner can fasten the coolant supply tap to the radiator and thereby make it cooler. With a two-pipe heating system at home, the same water pressure in the entire heating main, which means that you can take a weaker pump and it will cope.
Given the small hydraulic pressure of the water in the system, thinner pipes are also suitable for heating a two-story house.
With double pipe private house heating system each radiator can be replaced, removed, cleaned and this will not affect the operation of the system. To carry out such manipulations with a one-pipe system, you will have to stop the boiler, drain the water.
One, two floors or more?
Two-pipe heating of a private house to cope with the heating of any number of floors, the main thing is to choose the boiler power correctly. In rare cases, it is mounted with natural circulation. However, today this is not a very popular method that reduces the efficiency of the system, rare in modern heating schemes of a private house.
If a collector is installed
It is important to choose the right place for the collector or comb. The length of the track with a two-pipe heating system of a private house to each battery should be approximately the same.
If this parameter is not taken into account in the scheme of two-pipe heating of a private house, the pressure on the highway can vary. This will complicate the setup of the system. The best option for installing a collector with a two-pipe heating system of a two-story house is in a place equidistant from each of the batteries.
Pipes for heating
It should be noted that the number of pipes required for laying a route with a two-pipe heating system of a two-story house will be twice that for a single-pipe system. Naturally, this will increase the overall estimate. Pipes are suitable polypropylene, metal-plastic or copper. But galvanized should not be purchased.
