Prevention of systems of water heating in private house
Every summer, the urban heating network carried out a complex of actions for repair and testing of backbone networks. Autonomous system of water heating is no exception, on the contrary, they require even more attention. About summer service water heating we will cover in this article.
The warm season is the suitable period to drain from the heating system coolant, diagnose equipment and boiler to check the piping system. Faults easier to resolve in the idle time of the heating system, than to deal with the cold in case of failure of equipment in the winter.
The composition and procedure of preventive maintenanceTo maintain efficiency of water heating there is a range of activities. Certain types of work carried out with varying frequency.
Annually:
Routine inspection of gas boilers. Health check automation. Test alarms the boiler room. Inspection/cleaning of chimneys. Examination of the heating pipe.
Once in 3-5 years can also be carried out:
System test high pressure. Chemical flushing system. Replacement of the coolant. Calibration of devices in the market. It is clear that the frequency of carrying out certain activities — especially individual concept. For example, when used in the heating of well and borehole water is recommended to conduct an annual washing without chemicals, but if there is a plunger pump — annually to test the system pressurized. More specific recommendations give manufacturers of equipment and organization, mount system.
Drain and replace the water, inspection of piping and fittingsto avoid corrosion of steel pipelines, they are kept constantly filled with water. This rule does not apply for systems with plastic pipes, however, if the boiler has a heat exchanger made of black iron, allowed the discharge of water only when the closed valves on the pipes direct and reverse flow.
The water is drained for replacement or flushing the system, repair of pipelines and connections. The inspection of pipelines starting from the boiler and follow the circle, starting with the straight pipe flow. Leaks are often local and periodic in nature, most of them are not detected during the heating season. However, to detect the location of the leak can be the characteristic marks: the white or rusty plaque, divorce from the small puddles of water, the color change of the reeling sealant. Even with weak signs of leakage should Repack eviction or connection or to seal radiator sections.
Replace the water in the heating system is in the final stages of prevention, it is recommended before the beginning of each new heating season no later than 30-40 days in advance. The water from the system is drained and washed from the pipes formed deposits by applying pressure at the top point of the path through the pipe direct injection. Automatic washing liquid is drained until it is lightening, then the system is filled with water through a pipe bottom feeder under slight pressure.
Boilers and automaticelectric boilers Maintenance includes inspection of the heating elements, the audit of the launcher equipment and the hauling of the electrical connections. The heating elements are removed from the bulb, remove the loose scale deposits and remove the crust of plaque cleaner. The starters should be addressed to bring silver-plated contacts to Shine a skin-nulevkoy. All connections of cables and wires need to let go 2/3 of the clamp and tighten again.
Comprehensive maintenance of the boiler can only be performed by a specialized organization, but a lot depends on the owner. First of all, be sure to implement:
When you comprehensive the doctor will perform all these actions, and adjust the fuel delivery set up and test automation, analyze the composition of the exhaust gases.
Service solid fuel boilers includes the first comprehensive cleaning of the furnace, the pyrolysis chamber and flue channels. Cleaning is carried out with a wire brush, removing metal deposits and scale, but not clearing the surface to a Shine. This does not apply to heat exchangers: the surface must be as clean as possible.
Chemical flushing of the system and how to dothe Regularity of the chemical flushing depends on the quality of the water used. Many do not wash the system with a special coolant, which is normal. But the use of water associated with the formation of scale and other deposits that reduce the efficiency of heat transfer and significantly increase fuel consumption.
System flushing is performed by means of a special pumping installation, which can be rented. Wash the system with a special solution of cleaning chemicals, which are chosen according to the type of pipes, radiators and heat exchanger material in the boiler. In private cases, the boiler is washed separately.
When flushing it is important to close the valves all accessories: expansion tank, pumps, bleed valves, etc. At one point the ring of the pipeline has to be shut down and on both sides of the shutter are arranged pipes for connecting the flush pipes.
Rinsing is carried out in two stages: first pumped up the system with chemical for 40-60 minutes, then wash away the chemicals with clean water several times.
Test high blood pressureQuite often, after washing, open the small leaks on the pipe connections. To ensure their absence, a system experiencing high pressure. Usually it is 0,4–0,6 MPa. For pumping the incompressible fluid in the system is used plunger pump.
The test pressure hold for at least 20 minutes, during this time, conducted an inspection of joints and welds, concealed pipework are checked for hearing. If during the tests the pressure has not fallen by more than 0.01 MPa, the system meets standards of integrity.
Hydraulic tests carried out immediately after washing when disconnected from the system and the additional equipment.
Preparation and replacement of coolantIn most of the Autonomous heating systems acts as a coolant with tap water and it's not quite right. Unprepared water contains large amount of salts and oxygen, which causes scale deposition and metal corrosion.
The best option for heating systems — collected rainwater. Possible use of water after treatment by reverse osmosis or boiling. Also in sale you can find special inhibitors that block the effects of salts and oxygen, but such tools are very specific to use with certain pipe materials, gaskets and radiators. In the General case, a good solution is to set the heating the simplest to recharge the filter system. published
