Gas ovens are less preferred than electric ovens since they require user awareness (safety, use and follow-up).
Electric ovens should be safe in terms of energy efficiency, heat insulation, temperature controls, and safe in terms of technical features and electrical equipment.
Gas furnaces, combustion-safe, natural gas and LPG adjustable equipment, lighter spark plugs in the design that will not break during the usage stages, cleanable design in liquid overflows, (preferably) electric eye, meeting the criteria showing product safety. (GAZMER approved)
Microwave ovens, door insulation (to prevent radiation spread), design and quality, compliance with the criteria showing product safety, expertise of the manufacturer.
Economical Use
Place the trays by preheating the ovens (except the microwave). It is important in terms of cooking quality.
Ensure that the doors are closed properly.
Taking into account the internal temperature of the oven, you can turn off the oven and save energy before cooking time (5-10 minutes).
In ovens with multiple trays, trays should not be removed even if they are not used (for better circulation of heat circulation).
Depending on the feature of the food to be cooked, water is placed in the lower tray, allowing the food to cook before it dries.
You should select the heat and cooking settings of the appliance (mentioned in the manual) according to the characteristics of the food.
When the voltage is low, the use of the furnace will cause more energy consumption.
(Efficiency of energy is important in terms of cooking quality and energy saving. Request the solution of the negativities from the energy supply company.)

Individual air conditioners are effective in the area to be used. In single indoor unit systems, the desired efficiency can not be obtained in cooling or heating the entire room or partitions around.
Expert opinion should be obtained during the purchasing stages such as the external isolation of the environment to be used - geographical conditions, volume, heat sources and the conservation of the produced heat, the number of people in the environment, and the suitability of the installation place of the device.
Air conditioners selected according to their capacity will be effective in the efficiency of the energy, economic life and efficiency of the device.
Air conditioning assembly quality directly affects the performance of the device. Gas permeability and external insulation of the gas circulation pipes between the indoor-outdoor unit affect 30% efficiency.
The sound level of the products is very important for living spaces.
Products that work with gases that do not harm energy efficiency and the environment should be preferred.
It must be ensured that product safety meets international standards in terms of production criteria, human health and technology.
Adequacy of service services, before and after sales service procedure, warranty terms in maintenance and possible breakdown.
Suitability of indoor-outdoor unit dimensions to mounting areas.
Products of faults identified on the screen (with the Fault Code).
Economical Use;
The selection of the product was made according to the media capacity.
Annual periodic maintenance (Indoor outdoor unit) condenser - cleaning of answers and filters)
Door windows are closed while the device is operating
Reducing heat sources as much as possible, solar heat

The area to be used, geographical conditions, isolation of the environment, number of honeycomb and slices (capacity calculation) to be done by experts.
The expertise of the manufacturer, product safety,
Fuel saving (condensing-vented, hermetic, semi-hermetic, combi boilers)
After Sales Service procedures, warranty terms and times.
Products whose faults are identified on the screen (with fault codes).
Economical Use;
The boiler, which is operated in short time intervals (on-off), will consume more fuel and will be useful in terms of the life of the device. In order to prevent damage to the boiler pump and to increase the industrial life, it should be run regularly with at least 3 radiators in low setting.
Periodically maintained combi boilers are important in terms of fuel and efficiency.
It will ensure that the heat remains in the internal environment with the plates between the radiator and the walls (aluminum foil and insulation).
Maintenance;
Cleaning of residues, filters and strainers in the installation and gas leakage test should be done at the beginning of the season every year. If the device is chimney, chimney control and cleaning should be done. Since gas and pressurized water work with the system, combi boilers should be made by technically qualified personnel who know the system well.
In case of failure, please follow the warnings in the user manual. If the problem persists, request technical support from the authorities.

Product safety is important as they will often work out of your control.
Sufficiency in terms of required and basic features,
Program variety in washing and dishwashers; usage errors will negatively affect the product to be washed and the costs of purchase.
"Features other than need should not be preferred."
Energy, water and detergent efficiency are important for the home economy.
Spinning the laundry at high speed will cause it to deform early. Since full drying cannot be achieved, high speed should not be preferred in terms of the economic life of the device.
Economical Use;
A program should be selected according to the type, properties and dirtiness of the laundry or dishes to be washed.
Normal or long programs should not be selected instead of short programs
Consumer misleaders, (detergents and softeners) are exaggerated with exaggerated scales and advertisements in washing and dishwashers.
In order to increase the effect of the consumer (detergent sales in the markets and on the internet), which constitute the most important part of the home economy, it causes the consumers to be misled with the expressions (referring together with the brands, manufacturer's brand recommendation).
The lime rate in the water varies according to the geographical regions. Lime rates in city waters do not cause malfunctions to the extent that they are processed in detergents (TV and newspaper ads) used in washing and dishwashers. According to SHD statistics; repair costs arising from lime of the devices do not exceed the maximum (8%) of the cost spent on these chemicals. Therefore, it is possible to save 65% (with solution options) of these expenses.
Note: The most suitable product to be used in the washers should be selected according to the pollution rate of the water and the product to be washed. It is possible to meet this need, contrary to what is known, with technical service recommendations at lower costs.

Energy Saving Measures in the Use of Refrigerators
Note that there is no product on your device.
Do not load above your needs in foods to be stored.
Keep food covered.
Store the foods stored in the bottom freeze in edible sizes.
Keep the device away from heat sources (stove, oven, radiator, sunlight, etc.).
Doors should not be left open unless it is mandatory,
Condenser cleaning should be done every 6 months (dusting will decrease the efficiency of the coolant).
The device should be operated in a temperature range compatible with the seasonal conditions.
During the refreshing of the ice, it is contributed to the cooling by putting the old ice in the cooler section.

ENERGY EFFICIENCY
For the efficient use of electrical appliances,
Using the devices in accordance with the user guides and my product features that will benefit,
Devices will spend a lot of energy due to the energy quality (negativities such as low or high voltage, old energy installation). For these problems, be sure to alert the electricity distribution companies.
In case of malfunction to the devices, make sure that the original part has been replaced.
We know that it is used in the services provided with business cards, brochures, advertising tools, through communication tools (especially the internet), brands and logos (mostly by informal special services), and in the repairs, it is implemented with counterpart industry spare parts away from exorbitant prices and consumer safety.
For this reason, we recommend that you get service from the official websites and official services of the brands.
You can obtain the collection of your device's breakdown expenses arising from the voltage problem (authorized service and a qualified electrician) by applying to the Electricity Distribution company.
