How to Choose a Gas Heater Correctly: Power, Safety, and Practical Tips
Choosing the wrong heating system means unevenly distributed heat in the room, increased utility bills, and, most importantly, constant anxiety over safety.
In this article, we will discuss in detail how to choose the ideal model for your home, what technical specifications to pay attention to, and how to avoid unnecessary expenses.
How to Choose Gas Heater Power Based on Area?
When purchasing any type of heater, the first and most important step is to correctly determine its power output.
How to Know if a Specific Model Is Enough for Our Room?
There is a fairly simple and practical rule for this: under standard ceiling conditions (approximately 2.7 - 3 meters), 1 kW (1000 W) of power completely and comfortably heats 10-12 square meters.
If you are wondering what kind of gas heater is needed for an area of 40, 60, 80, 100, or 120 square meters, the calculation looks as follows:
- For a 40 square meter room, a 4000 W (4 kW) power model is optimal. For 60 square meters, you will need approximately 6000 W.
- To heat 80 square meters, an appliance with a power output of 8000-8500 W is recommended.
- Meanwhile, a space from 100 to 120 square meters requires a 10000 W (10 kW) power device.
However, knowing only the square footage is not enough. When selecting, be sure to consider the thermal insulation of the building. A well-insulated area with energy-efficient windows requires much less power and retains heat longer. But if your apartment is a corner unit, or located on the first/top floor where heat loss is high, it is better to choose an appliance that is 15-20% more powerful so that the engine operates without excessive load and energy efficiency is maintained as much as possible.
What Is the Difference Between Systems with Open and Closed Combustion Chambers?
Safety is the single component where compromise is unacceptable. When exploring models on the market, you will inevitably come across the term "closed combustion chamber." What is the difference between it and old, open-type systems?
An open combustion chamber takes the oxygen required for operation directly from the room where it is installed. This often leads to drying out the air in the room and, in the absence of proper ventilation, carries certain risks. By modern standards, the best choice is a closed combustion chamber. Such a system uses a special double-walled pipe to draw air directly from the street outside and discharges the exhaust generated by combustion in isolation back outside. This mechanism ensures that no poisonous substances leak into the living space, which keeps the air in the room constantly healthy.
Heat Exchanger Material: Which Is More Effective, Cast Iron or Steel?
When selecting an appliance, it is important to know what material its internal part - the heat exchanger - is made of. Two main types of materials are found on the market: cast iron and steel. Both have their advantages.
A cast-iron heat exchanger stands out for its exceptional durability. Although it heats up relatively slowly and takes a bit more time to bring the room to the desired temperature, it retains heat for a very long time after being turned off and continues to heat the room. As for a steel heat exchanger, it heats up extremely fast and begins heating the space immediately upon turning on, which is very convenient, but steel cools down much faster and has a slightly shorter service life compared to cast iron.
Here we should also answer one of the most common questions: what causes the strange "clicking" sound when the appliance ignites or operates, and is it dangerous?
This clicking sound is simply caused by the thermal expansion or contraction of the metal heat exchanger during rapid temperature changes. This is a natural law of physics and definitely does not indicate a malfunction of the appliance.
How Does the Protection System Work and Is It Safe to Leave the Appliance On at Night?
Many consumers fear gas-powered devices and hesitate to leave them turned on overnight. How justified is this fear? Modern gas heaters are equipped with multi-stage safety mechanisms. Consequently, leaving a properly functioning appliance on at night is completely safe if it is equipped with a closed combustion chamber and has appropriate ventilation.
One of the key functions used in modern models is gas control. This is an innovative protection system that constantly monitors the combustion process. If the flame accidentally goes out due to strong wind, a pressure drop, or any other reason, the gas control mechanism reacts in seconds and automatically shuts off the gas supply completely. This prevents gas accumulation in the room and tragic accidents.
However, you must remember that the safety of any equipment, even the most expensive, is directly tied to its proper installation. Installation must be performed by a certified and experienced professional. An unqualified technician often makes mistakes when connecting pipes, which can make even the most reliable appliance hazardous.
Brands, Models, and the "Karma" Phenomenon in Georgia
An interesting trend has taken root in our reality - most consumers refer to any gas heater as "Karma." Phrases like gas heater karma or simply karma heater have become synonymous in everyday conversation. In reality, Karma is a specific, top-quality Czech brand that established itself on the Georgian market years ago through its reliability to the extent that its name became a generic term.
On Kontakt.ge, both original Karma models and other reliable, leading manufacturers such as Ersel and Akog are presented. Our assortment includes models ranging from 3000 W to 10000 W in power, allowing you to heat a small bedroom (30m²) as well as a large living room (120-130m²). In terms of design, the choice is diverse - black, beige, white, or combined colors blend perfectly with any interior.
Just as you can purchase small household appliances or major household appliances from us, we also strive to cover all leading brands in climate control equipment and offer you the highest quality.

Frequently Asked Questions
What is the difference between open and closed combustion chamber gas heaters?
An open combustion chamber draws oxygen from the room where it is installed, while a closed chamber draws air from outside and vents exhaust gases outside as well.
How should the power of a gas heater be selected based on the room size?
Under standard ceiling height conditions, 1 kW of power heats approximately 10–12 square meters. When selecting the exact capacity, consider the building's insulation; a well-insulated space requires less power.
Which gas heater is more efficient: cast iron or steel heat exchanger?
A cast iron heat exchanger is more durable and retains heat longer, though it heats up slowly. A steel heat exchanger heats up quickly and warms the room fast, but it cools down much faster and has a shorter service life.
Is it safe to leave a gas heater on overnight?
It is safe to leave a modern, properly functioning gas heater on overnight, provided it is equipped with safety systems and adequate ventilation is ensured.
What function does the gas control system perform and how does it work?
Gas control is a safety mechanism that automatically shuts off the gas supply if the flame accidentally goes out.
What causes the "clicking" sound when a gas heater ignites, and is it dangerous?
The clicking sound is caused by the thermal expansion or contraction of the metal heat exchanger due to temperature changes; it is generally not dangerous.
