The two-pipe heating system of the house has the only drawback over the one-pipe one - it is the double amount of materials. As for the user parameters of heating a two-story house, the advantage is obvious.
Pros of a two-pipe heating system
In a private house, it is quite possible to equip a one-pipe system, however, all rooms will warm up unevenly. In the last radiator along the course of the coolant, the water comes up after it warms up all the previous ones. No matter how the heating main is laid: upper or lower, the water temperature in different batteries will be very different.
Double-pipe heating of a private house frees the owners from thinking about the temperature of the batteries. It is possible to lay pipes by ray method or horizontal. In any case, the water temperature does not differ in all radiators in the house. If desired, the owner can screw the coolant supply valve to the radiator and thereby make it cooler. With a two-pipe heating system at home, the entire heating main has the same water pressure, which means that you can take a weaker pump and it will cope.
Given the low hydraulic pressure of the water in the system, thinner pipes are also suitable for heating a two-story house.
With two-pipe heating system of a private house each of the radiators can be replaced, removed, cleaned and this will not affect the operation of the system in any way. 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 can cope with heating any number of floors, the main thing is to choose the right boiler power. In rare cases, it is installed with natural circulation. However, today this is not a very popular method that reduces the efficiency of the system, which is rare in modern heating schemes for a private house.
If a collector is installed
It is important to choose the right place for the manifold or manifold. The length of the route 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 two-pipe heating scheme of a private house, the pressure on the highway may change. This will complicate the setup of the system. The most optimal 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.
Heating pipes
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 as large as that for a one-pipe system. Naturally, this will increase the overall estimate. Pipes are suitable for polypropylene, metal-plastic or copper. But galvanized ones should not be purchased.
