Our Gas stove is used for cooking food, twice a day, and we use an 48kg bottle of gas every 8 months, at around R1050 per refill.How much cheaper is gas than electricity? I understand that it's a difficult comparison as a 1 litre pot of water will boil faster on gas than an electric stove but can someone give a ball park figure?
Only if you connect it into the house wiring, put the gennie on a stoep and run an extension into which you plug lights and TV and you're golden.
It depends on the generator. The generators in the article, can not be connected to a fixed electrical installation (i.e. your DB). You can only connect appliances directly to it.
That's if you want to go all out - you buy a generator with a self-starter, put in suitable housing (with exhaust provision), and get an electrician to wire it in, with a 3-way switch (mains, off, generator) and a push-button to start the generator. Only add to the gennie circuitry the priority items you want it to power, or that fall within its capacity.
