Common burners on the market include: single-stage, two-stage, and PLC proportional control.
Each of these three types of burners has its advantages, and we should choose based on our needs and budget.
Ranked by ease of flame adjustment: PLC proportional control > two-stage > one-stage.
Ranked by price: PLC proportional control > two-stage > one-stage.
From this ranking, we can see that the ease of flame adjustment is directly linked to price. Why is this?
Proportional control uses pre-set settings for air and gas flow rates. By selecting specific buttons, the flame size can be adjusted in steps.
Two-stage control, as the name suggests, uses pre-set settings for two specific air and gas flow rates.
One-stage control involves manually adjusting the gas and air volume to adjust the flame.
If you need to precisely heat to a specific temperature and don't want to spend too much time adjusting, then proportional control is definitely the way to go.
If you are particularly confident in your ability to adjust the flame size and need to save costs, it is recommended to purchase a single stage fire.
