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 designed especially meticulously.
Of all the existing types of wiring for double-circuit heating of a private house with a heated area above 110 sq. meters it is best to mount a two-pipe system.
The heating system includes:
- Boiler;
- Pipeline;
- Batteries;
- Fitting;
- Sensors;
- Valve.
Heating schemes for a private house
Schemes of a two-circuit heating system are divided into:
- Two-pipe and one-pipe;
- Top wiring or bottom wiring;
- With vertical or horizontal risers;
- With main water supply or dead-end;
- With natural circulation or forced.
The best type of heating a private house with a double-circuit boiler is a system with forced movement of the coolant, including a boiler, a collector, a pipe line, an expansion tank, and batteries. The water is driven by a pump.
Heating piping
Double-circuit private house heating system can be with one-pipe, collector or two-pipe decoupling system. The two-pipe system is more practical, it allows you to turn off any number of radiators if necessary. In addition, underfloor heating and heated towel rails can be connected to a two-pipe system. The expansion tank can be installed on the second floor.
According to the scheme of a two-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 are not suitable for laying heating mains, they quickly begin to rust.
The most expensive pipes for double-circuit heating in a two-story house are copper pipes. They do not rust and are very temperature and pressure resistant. Copper pipes are soldered together. You won't have to change them for the next 50 years, so they can be hidden in 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 temperature and pressure. But they can deform during operation and start to pass.
Sometimes stainless steel or galvanized pipes are used in a double-circuit heating system of a private house. They are mounted on a thread, but to make such a route requires skill and experience.
Heating boiler location
The boiler can be hung on the wall in the kitchen or closet. In this case, it must be borne in mind that when operating, the equipment emits a small hum. When installing a double-circuit heating of a private house, the boiler can be installed on the floor of the utility room.
