Electric/Gas Heater

Electric and gas household heaters are among the common and widely used devices for heating homes and offices, which have a wide range of models.In the following, the technical specifications, models, brands and the best purchase prices of electric and gas household heaters have been reviewed.

guide to check and choose household heaters, electric and gas heaters

As you know, a heater is a portable (portable and portable) heating device and generally does not require special equipment for use. This device starts working after connecting to the energy source (electricity or gas). This energy source is usually electricity, natural gas, oil, etc. Electric and gas heaters are one of the most widely used additional heating equipment in buildings and houses. When using different types of heaters, one should pay attention to points that, if not followed, can cause irreparable damage. The correct choice of the type of fuel, heating capacity, etc. of the required electric or gas heater, in addition to the economic justification at the time of purchasing goods, can reduce energy consumption and operating costs. You can make the smartest choice by checking the types of gas and electric heaters in terms of fuel type, heating capacity, accessories such as a thermostat, fan, towel dryer, heater model, and brand. In the following, we present some tips on how to check, compare, choose, and buy an electric heater or a gas heater, which are the most used heating devices in Iran.

Selecting a heater for closed spaces

There is no limit to the use of heaters in homes and office environments, as long as the capacity is taken into account and safety precautions are observed. But pay attention, if you want to heat the entire room with a heater, we suggest using models with fans and then electric radiators in order of priority.

Selecting a heater for open spaces

The best way to heat open spaces or large halls such as sheds, where it is not possible to heat the entire space simply, is to use a heater with a radiant heating system, in this case, the people who are near the heater will The radiation of the heater will be warm and there will be no need to heat the whole hall or that open space. Usually, the fuel required for such heaters is gas. (Refer to "radiant heaters" in the heaters and hot air furnaces section on the Damatajhiz HVAC website).

types of heaters

The types of heaters available in the market are:

electric heater

Generally electric heaters Regardless of the heating capacity and their different brands, are made in two radiant and fan models. Among the advantages of electric heaters are It is possible to mention their reasonable price, small size, portability, and high efficiency.
The important point in using electric heaters is that electric heaters are not designed for continuous heating in large environments. Using an electric heater in such a situation will lead to high electricity costs and endanger the safety of the residents.

Radiant electric heater or electric heater

As its name suggests, in a radiant electric heater, the heat created by the radiation of the element (infrared waves) is provided in the heater.
In a radiant heater, several heating elements are used, and usually a shiny and reflective surface. It is placed in the back part of the elements so that the heat energy of the electric elements is radiated towards the environment. A radiant electric heater with elements usually converts 86% of the electricity energy into radiant energy and the electricity consumption of each element is based on the size The capacity is about 400 to 800 watts, so a device that has 3 elements usually consumes about 1200 to 2400 watts of electricity, which has a lower electricity consumption compared to larger types of electric heaters. In larger electric heaters, each element consumes about 600 or even 800 watts of electricity, which completely depends on the size and length of the electric heater element.

Fan heater or fan electric heater (ventilation fan)

In the front part of the electric fan heater element, there is a fan that transfers the heat of the element to the outside of the device and causes the environment to heat up; The use of a fan causes better air circulation and faster heating of the environment.
This type of design makes it possible to build smaller heaters and increases their efficiency.
Electric heaters with fans They are usually equipped with a thermostat and an automatic sensor, in case the environment heats up, they will turn off the device automatically. These heaters usually have a high level of safety, but they are not suitable for use in environments with high humidity and they need to comply with certain standards. Of course, in some new electric heater models, both heating methods (radiation-fan) are used.

Electric heater suitable for bathrooms and humid environments

The electric heaters suitable for use in the bathroom are of radiant or electric fan type. These heaters, which are made to be installed in the bathroom, have a higher safety level, i.e. IP24, and their on/off switch is attached to the device as a pendant. The installation of such heaters must be done with a waterproof electric wire, which makes it completely safe and secure in environments with 100% humidity, such as the bathroom. Some of these heaters are made of infrared elements (which are mainly made of ceramic) and the heat created by the radiation system causes the environment to heat up. Finally, there are other types of these heaters that are suitable for use in bathrooms and in environments with water They have direct contact, and cannot be installed. These models are generally wall-mounted, and in some models, a section for placing towels is also built into them.

Buying household heaters, electric and gas heaters

Choosing a heater should be done according to things like heating rate, fuel type, model and brand, thermostat, and accessories. To choose and buy a home heater, electric, or gas heater, you should consider the size of the house or the place where the heater is supposed to provide heat. Small heaters or heaters with low energy production capacity are suitable for bedrooms and small spaces and cannot be used in large homes.

The necessity of choosing a household heater and an electric heater

If your bedroom is heated with a heating system, but on some cold days of the year, the existing heating does not meet your heating needs, we suggest buying an electric fan heater.
Principles for heating In the bedroom, we do not recommend the use of radiant electric heaters, because radiant heaters keep the room lit at night with the light they create, and there is also a risk of fire in the possible plastic materials in front of the heaters.
If the sound of the fan of the electric heater bothers you, or if your room does not have any heating system, then you can use an electric radiator.
The electric radiator has advantages that make it suitable for heating in any way. It makes the house and especially the bedroom safe. Electric radiators are available in different capacities, from 7 blades to 15 blades, with drying towels, and in models with and without fans. To know the specifications of their types and prices, you can go to the heating and engine room department, steel radiators group. , panel and electric, as well as the home office section, refer to the heating radiator group on this site.

general guide for buying a gas heater

Although central heating systems in buildings are constantly expanding, the use of electric and gas heaters is still one of the most common methods of heating the house.
In our country, due to the existence of cheap and accessible natural gas sources, This fuel is the main fuel consumed by people in the cold seasons of the year. For this reason, gas heaters are the main means of providing heating for Iranians in the cold seasons of the year. The use of gas heaters can also have negative consequences, including bitter accidents that occur every year in the cold season due to not observing the principles. First, the safety of gas-burning appliances takes place. In order to avoid accidents and also to make better use of heat energy and make our homes warmer, we should pay more attention to safety tips and standards when buying a gas heater.

Gas heater capacity calculation calculation

The most important factor in choosing a heater is the area of ​​the living room of the house or the desired space for installing the heater. (Note that installing a gas heater in the bedroom is not recommended). To get the required amount of heating, consider about 150 kilocalories per meter.
Note: It is better to leave the thought of buying gas heaters without a chimney out of your mind because the use of heaters without a chimney in environments A package such as a living room, bedroom, and any place that does not have good ventilation is very dangerous and prohibited.
This type of heater can only be used in semi-open places (such as stores and shops that enter and there are a lot of people going out with them) so that fresh air flows in it because gas needs oxygen from the air in the environment to burn, and in case of lack of air, the amount of oxygen decreases, the amount of monoxide and carbon dioxide increases, and It then leads to poisoning and gassing. The same thing that non-standard heaters bring to our homes in the name of silent death.
It should be noted that if you use chimneyless heaters, be sure to buy those that are equipped with the ODS system. Because according to the standard, all chimneyless heaters must be equipped with this system.

Important points of gas heater

The important points about the types of gas heaters are as follows:

• Generally, Gas heaters are different types, which can be mentioned as wall gas heaters, floor gas heaters, and gas heaters without chimneys.
• Wall-mounted gas heaters occupy less space and have less heating power than floor-mounted gas heaters.
• Gas heaters are installed wall-to-wall and with the end of the cold season, opening and moving them until the winter of the following year and installing them again will be less of a hassle. so that it does not occupy extra space in the house. The heater must have after-sales service (which is stated in the warranty booklet) and must be installed and operated by authorized service workers. Initial after-sales services include installation, commissioning, and testing of the release of carbon monoxide gases from the chimney of the gas heater.
• Installing the heater according to the standards plays an important role in increasing its safety. When installing a gas heater, attention should be paid to the chimney outlet, because the colorless, odorless, and undetectable CO gas that is produced when the gas heater is on must be discharged through the standard chimney. After installing and using the heater, periodic control and service should be done to ensure the ventilation and chimney conditions.
• It should be noted that the gas heater should never be turned on without connecting it to the chimney, because carbon monoxide and deadly gases spread quickly in the house, so it should always be ensured that the chimney path is open and the pipe is not leaking and the chimney cap is healthy. At the end of the chimney, it is installed outside the building, making sure that this control should be done every year at the beginning of the cold season and before turning on the heater.
• Please note that after installing the gas heater, the gas heater pipe (chimney) should heat up quickly and the flame of the heater should be blue.
• If the chimney pipe of the heater does not heat up after installing and turning on the heater, it means that the chimney is not installed in a principled and standard manner and the toxic combustion gases are not removed from the house or the place where the gas heater is installed, in which case the problem is Take it seriously and follow up until the problem is solved and the combustion gases flow and the chimney body heats up.
• Note that the length of the gas hose from the inlet gas valve to the heater should not exceed 150 cm, because it is very dangerous to use long gas hoses to deliver gas to different parts of the house, and reinforced rubber hoses should be used. should be used for gas, suitable metal fasteners should also be used to secure the gas hoses.
• Avoid placing the heater pipe in a separate bucket of water due to the spread of toxic and deadly carbon monoxide gas and silent death.
• ODS system and thermal sensor system: In general, you should be careful when choosing gas heaters so that it is written on the carton or manual that the device is equipped with an oxygen-sensitive system (ODS). , a system that, according to experts in the installation and repair of gas-burning devices, unfortunately, is not installed in many heaters of different companies, and usually in the production of heaters, companies are limited to installing a thermal sensor. Of course, thermal sensors also reduce the level of risk caused by accidents by increasing safety, but they are not enough on their own.
• The thermal sensor system works in such a way that when the flame and the heat of the heater body increase, it is activated and the flame is turned off. But in the gas flow cut safety system, as a result of oxygen reduction (ODS), if the ambient oxygen drops to 18% for any reason, the heater is turned off and the system automatically cuts off the gas flow to the heater. that this will save the lives of the people in the environment.
• The presence of a thermocouple safety system that automatically cuts off the gas flow when the heater is turned off is mandatory for all gas heater manufacturers.

Take the energy label seriously

One of the things that you should pay attention to when buying a gas heater is the energy category of the heater and its net heat production efficiency, this energy category of the heater is indicated by a transparent label on it. With English letters, they show that the closer it is to the letter A or the beginning of the English alphabet, the higher the net efficiency of the heater, and the closer it is to the last letter of the alphabet, the lower the net efficiency. So it is better to buy heaters whose label shows one of the first letters of the English alphabet.

If a radiator has already been installed in the desired space, but it does not provide the necessary heat, it is suggested to use electric heaters of fan models to circulate the air while heating the room. If there is only one person in a hall and it is not possible to heat the entire space, we suggest using an electric radiant heater. In this case, the heater should be placed on the floor and next to that person. If the desired location does not allow placing an electric heater of this size, you can use a desktop fan heater.
