Due to the fact that the coolant in two-story houses needs to rise several meters higher, double-circuit heating in a two-story house needs to be especially meticulously designed.
Of all the existing types of wiring for double-circuit heating of a private house with a heated area above 110 square meters. meters is best to mount a two-pipe system.
The heating system includes:
- Boiler;
- Pipeline;
- Batteries
- Fitting;
- Sensors
- Valve.
Private house heating schemes
Schemes of a dual-circuit heating system are divided into:
- Two-pipe and one-pipe;
- With the top wiring or with the bottom;
- With vertical risers or horizontal;
- With main water supply or dead end;
- With natural circulation or forced.
The best type of heating a private house by a double-circuit boiler is a system with forced movement of a coolant, including a boiler, a collector, a pipe, an expansion tank, and batteries. Water is driven by a pump.
Routing heating pipes
Double circuit private house heating system can be with a single-pipe, collector or two-pipe decoupling system. The two-pipe system is more practical, it allows you to disable, if necessary, any number of radiators. In addition, underfloor heating, heated towel rails can be connected to the two-pipe system. An expansion tank can be installed on the second floor.
According to the scheme of the dual-circuit heating system, it is advisable to install risers supplying the coolant to the second floor near the boiler.
Choosing pipes for the system
Steel pipes for heating mains are not suitable, they quickly begin to rust.
The most expensive pipes for double-circuit heating in a two-story house are copper. They do not rust, are very resistant to temperature and pressure. Copper pipes are soldered together. They will not have to be changed in the next 50 years, so they can be hidden in the walls. The disadvantage of such wiring is that they are very expensive.
When heating a private house with a double-circuit boiler, metal-plastic or polymer pipes are most often installed. They are easy to install, withstand high temperatures and pressures. But they can be deformed during operation and begin to pass.
Sometimes in a double-circuit heating system of a private house, stainless steel pipes or galvanized pipes are used. They are mounted on the thread, but to conduct such a route, you need skill and experience.
Location of the heating boiler
The boiler can be hung on the wall in the kitchen or pantry. In this case, it must be borne in mind that when working, the equipment emits a small buzz. When installing double-circuit heating of a private house, the boiler can be installed on the floor of the utility room.
