First of all, let’s talk about LPG gas-powered cook-tops, which are usually present in all of our homes. In this domestic or commercial LPG cylinder is lit by connecting it to the regulator. Its cost is very less and the cost of refilling a cylinder in a month comes to about 1000 rupees. There is also a pipeline for gas refilling in metro cities. The help of an electric lighter is taken to start this domestic cook-top. Newer gas cook-tops are also coming with in-build lighters in which the gas cook-top will light up as soon as the knob is turned. Commercial cook-tops also come in gas only. The basic difference between this and a domestic cook-top is the size. In this, the size of the stove is available up to 60 inches wide. In this, the number of cook-tops can be from 6 to 8. Due to the high heat in this commercial cook-top, it is necessary to install an exhaust or chimney.
