Comparison Zilan ZLN 2830 vs Dedra DED9975

This parameter indicates how much fuel the heater consumes per hour when operating at maximum power. Therefore, it's crucial that many models have adjustment features, and some even come with a thermostat — in real life, these allow the device to operate mostly at medium or low levels, significantly reducing consumption compared to a constant maximum. Unlike the dry numbers of "full power," the scenario is more important for the buyer: higher consumption for quick warming and lower for maintaining temperature. For example, turn it on at maximum for 10–15 minutes, then reduce to maintenance mode — the gas bottle lasts longer than if kept at "full throttle" all evening.
