The Delonghi is on LPG, runs on three heat settings. Use it on max, and a full LPG cylinder will last approx 50hrs.
I'm also using a heavy duty koyo kero heater @ my home in Palam Vihar Gurgaon. It's an overkill even with the current cold wave conditions. This one (Dont know the model) is a Kero guzzler-can go thru' 10liters in about 10hrs but heats up a 1000(yes thousand)sq foot room. There smaller ones available in the market.
Would suggest the LPG heater as maintaining the Wick of the kero is cumbersom.
Also Kero costs 35buck a litre and then you get adulteration to top it all!!!
Natural Gas heating systems are the leading cause of carbon monoxide deaths in the United States, according to the U.S. Consumer Product Safety Commission. When a natural gas heating system malfunctions, it produces odorless carbon monoxide.
With no fumes or smoke to give warning, victims are easily asphyxiated ie posioned by the carbon monoxide.
