variety of equipment for stationary direct electric heating allows you to make the optimal choice for each room, depending on its functional purpose.
So, hallway, corridors and stairways better use of electric convectors - is the most cheap and easy mountable equipment.In the bathroom, toilet, sauna and kitchen can accommodate waterproof convectors or underfloor heating (but you can do both at the same time).
for bedrooms and children's rooms should be fine ceiling longwave infrared heaters that are simultaneously warm the floor, the carpet on it and the bed.But in the living and dining rooms is better to combine convectors and infrared panels.This allows you to create zones of increased thermal comfort.
When the house is a "winter garden" or something similar, that in these areas it is best to install infrared heaters, which create a natural microclimate for plants and energy savings.
If the house or apartment found freezing, s
What should be the power of electric heaters for summer cottage, not operated in winter?
better home insulation, the less heat loss and heating costs.Therefore, the heating power depends on the thermal insulation of the house and is calculated by experts.But on average it is 2 times smaller than is required for heating the house winter.
Question: What are the advantages of direct electric heating?
Answer: in one way or another polluting all kinds of heating, except electrical.Exhaust ventilation and pumps lead to additional noise and vibration.Leakage of gas and diesel fuel, coal dust adversely affect the respiratory tract and mucous membranes of man.In addition, the risk of fire or some other emergency situations when liquid and gaseous fuels is significantly higher than the electric heating.Leakage of toxic anti-freeze is dangerous to human health and can also cause serious damage to the building.
Modern electric heating systems do not desiccate air.Radiant infrared heaters and a "warm floor" does not create convection currents of air and dust.
Question: What are the characteristics of oil coolers?
Answer: Oil heaters are one of the most popular household heaters.By the way, all of the electric heaters with radiators called only this group.Generally radiators - a view of the heating system in the form of a container filled with a liquid (water or oil), which is a heating element.
operating principle of these options are relatively simple: inside a body made of steel or aluminum alloy is mineral oil, which is heated by the heating element.The device has the same metal edges as a conventional central heating radiator.Heating of the premises occurs gradually, the warmest spot - right next to the heater.
Many foreign manufacturers of products equipped with temperature controls, thermostats, timers and a fan, accelerating heat transfer.The power of oil heater is 1-2.5 kW.The temperature of the heating element and the housing are sometimes the same (more than 100 ° C), which is not very pleasant for the consumer - you can get burned.
Question: What is heater?
Answer: heater is used for primary or secondary space heating, domestic heating in the open air, as well as for drying damp walls, wood, etc.
represents a heater consisting of a fan and heater (PETN).Heater high power (more than 5 kW) is called a heat gun.Such equipment provides thermal effect by raising the temperature of the entire mass of air in the room.As a result, the heated air accumulates under the ceiling as the lighter.With a ceiling height of 4 m above the temperature difference between the floor and ceiling may reach more than 10 ° C.
Question: What are the advantages and disadvantages of such a system as a heating heaters?
Answer: «plus" of these appliances is the following:
- very quickly heat the air;
- protected against overheating;
- thanks to the thermostat automatically regulates the temperature and do not require shutdown;
- switched off in case of a fall.
Also, most modern heaters have special protection against accidental contact with water.
as "cons" of this system of electric heating should be called:
- produces a characteristic "buzzing" sound;
- zabivshayasya dust burning on a hot spiral, may issue an unpleasant odor.
Question: panel heaters What is design?
Answer: Electric convectors are a decorative protective metal casing with bottom openings for entry of cold air from above - to exit heated.In the lower part of the housing is mounted a heating element (heater) consisting of a conductive component, placed into ceramics and hermetically brazed to a steel pipe.Inside the cover of the unit is set safety sensor, which provides power off in case of overheating of the heating element in emergency situations.In operating mode, the temperature heating element, depending on the model and the manufacturer is in the range of 100 ° C.
This design and mode of operation of virtually no change room humidity, does not dry the air, do not burn oxygen and precipitated dust on the heating element.
Turning off the power does not lead to a breach of the functionality of the equipment, and after energizing electroconvector starts immediately.
Question: How is electroconvector?
Answer: special frame with four screws attached to any surface interior decoration, and it fits very convector.Protective decorative body is safe, its outdoor temperature is 45-65 °.Modern convectors splashproof and can be used in wet areas.
Question: panel heaters What are the disadvantages?
Answer: These heaters have common drawbacks of all convection system: formation of convection air currents that circulate around the room, carrying the dust and, as a result, create uneven heating of premises, especially in height, which is very important for low-rise buildingswith an unheated basement area.
Nevertheless, it is a very reliable equipment: the 2-year warranty lifetime of such devices is more than 15-20 years.When choosing a panel heaters must pay particular attention to the quality of manufacture of the heating element, the use of stainless steel and aluminum alloys.
Question: Argued that Heaters in a country house in harmony with the stove.How?
Answer: furnace in our environment is the most economical heating equipment, but it has several drawbacks:
- significant fluctuations in temperature in a heated room, sometimes constituting 7-10 ° C per day;
- well heated, as a rule, a single room (which houses the furnace).The other rooms (bedroom, bathroom, hallway, etc.) noticeably cooler;
- during prolonged absence of tenants house can cool down to freezing temperatures.
to warm the room cooled down stove should burn for about 12 hours.The repeated process of cooling and heating leads to a marked reduction in strength, and eventually the destruction of supporting structures of the building.Possible adverse effects, such as: wetting the walls, humidity, mold growth.
for heating the rest of the area rational use of stationary heaters.In the room with the furnace electroconvector will stabilize the temperature.Furthermore, in the absence of human-zero temperature is maintained.
Question: What are the characteristics of operation of the electric infrared heating?
Answer: compared with convection heating, which heats the air and from the heated objects in the long-wave infrared heating, as already mentioned, first of all heated objects, and then the heat is transferred from the objects of the air.Studies have shown that for a convection heating temperature gradient adjustment is 1,7-2,5 ° / m, and the warm air is naturally at the top and cold at the bottom.This is particularly important for country and cottage construction, as well as the first and basement floors of urban high-rise buildings, which are often the difference in temperature between the floor and the ceiling reaches 6-7 ° C.
under infrared heating temperature at the floor surface higher than the ceiling temperature gradient of approximately 0,3 ° / m.Under these conditions, a comfortable temperature at a height of 1.5 m can be reduced by 2-3 ° without compromising human health, since the floor temperature will be 18-19 °.
Question: What are the advantages of infrared heaters?
Answer: One advantage of infrared heating is the absence of convection currents, which significantly reduces the amount of dust in the air of the room.The area in which the infrared heating is used, the savings increases by 20-25% compared with convector.The apparent advantage and an additional thermal comfort is the fact that this form of heating all of the items, the floor, walls, etc.It is warmer than the air.
Question: What is the working principle of infrared heaters?
Answer: Infrared heaters - radiators transmitting surrounding objects through the infrared heat generated by them.The wavelength range of the radiation is close to the sun and good for human health.Such devices are heated primarily objects rather than air.In contrast to convective heating, only about 10% of the energy transferred by convection of the radiator, and the remaining 90% - radiation.Therefore, the combination of infrared heaters and modern management systems electrically saves up to 30% power.
Question: How are infrared heaters?
Answer: Dehumidifiers are usually mounted on the ceiling, although it is possible and wall mounting.This equipment is intended for basic or supplementary heating of premises and open spaces, as well as for use in drying processes.
Question: What are the disadvantages of infrared heating?
Answer: no shortage.However, there is one "but."Experts believe that the main purpose of infrared heaters - heating of large areas with high ceilings and poor insulation.It usually factory buildings, warehouses, vehicle maintenance, indoor sports and concert halls, exhibition halls, hangars and closed markets.For such facilities energy savings, taking into account the local nature of heating, it can reach 80%.However, it should be noted that the concrete floors without insulation significantly reduce the efficiency of the heating system.
Given that capital equipment costs are negligible, the installation is simple, and the preventive and maintenance activities are virtually absent, it becomes evident advantage of infrared heating.
Question: How does the heat-radiating film?
Answer: It is located on the floor under the carpet, tiles, parquet.The thermostat allows you to program the heating.It is only necessary to set the desired temperature and the system will turn on and off automatically, maintaining the set temperature.Used as a secondary and primary heating.Power consumption is a normal power incandescent bulbs.Scope: apartments, houses, swimming pools, restaurants and other public spaces.
The main advantages of this type of heating:
- the absence of bulky heating elements in the room;
- comfortable heat without temperature extremes;
- complete electrical safety;
- elementary mounting.
Question: heat radiating What is a mirror?
Answer: reflective layer in such a mirror is both a heating element.The surface temperature does not rise above 75 ° C, so a heater is completely fireproof.In the bath or sauna, a mirror does not fog up, do not change the set level of humidity.
