The heating system with natural circulation for a private home : a simple and economical

Advantages of heating with natural circulation for home

1. low cost.The low price of materials, installation and commissioning.The construction works without a pump, and hence reduced the cost of its purchase and payment of electricity.
2. Easy to install.Installation can be done independently, without the involvement of experts, because it does not require special skills.
3. long life.With proper installation is capable of serving more than 30 years.

Functional principle

heating medium under the influence of the temperature of the boiler is heated, its density decreases, and it goes up from their movement through the pipes.Passing pipes and radiators, the liquid temperature is lowered continuously, and when completing the circle, reaches the boiler, its temperature again below the water in the boiler.Accordingly, higher density, and it again pushes the hot liquid with a lower density.This happens continuously.The coolant does not stop its movement until the boiler is working.

Key elements of heating homes with natural circulation

standard set of elements is:

1. boiler;
2. pipes;
3. batteries and radiators;
4. Expansion tank;
5. Taps, valves;
6. Clamps.

How to mount

home heating system installing heating with natural circulation need to know and adhere to these rules:

1. All pipes should be placed under a bias towards water movement.

to the coolant could independently move through the pipes, they should be placed under bias.Optimum 0.005 M gradient.on linear meter pipe.

2. To a pressure tube was optimal, necessary to reduce the number of fittings, valves, filters and turns, as they provide additional resistance to gravitational pressure.Or increase the diameter of the pipe.

Two-pipe heating system wiring

two lines are applied at two-pipe heating wiring: feed, with hot water and receding, chilled.Turnpike connected in parallel, allowing you to regulate the temperature in each heated room.Two-pipe layout can be the top and bottom.

two pipe heating installation wiring:

1. steps up from the boiler conducting pipe and connect with the expansion tank;
2. Expansion tank set at the top of the entire structure (attic);
3. At the exit of the expansion tank, connect the supply line to the pipework;
4. We carry a tube of the wiring to the radiators and batteries;
5. from radiators and batteries derive the pipe to the return line, and from there to the boiler;
6. return pipe mount parallel supply line along its entire length;
7. Expansion tank supply the tube to drain excess fluid to drain.

Features install pipe heating system

-pipe heating wiring is easier and more cost-effective, due to the reduction in the number of pipes and radiators.

In this construction, the operation does not affect the location of the boiler and batteries.Even if they are placed at the same height, then the system will still function.

Expansion vessel capacity in this design may be only 25 liters.Fill the water it needs to be ¾ of the total volume and constantly monitor the water level.

Conclusions

Set in a small private house heating system with natural circulation - is the perfect solution.At the same time practical and convenient the system is ready to serve for many years.
