Gas Heaters
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.
