At our old place we always had a solid fuelled Rayburn, heated the kitchen, hot water and you could cook from it. However, my mum and I both have asthma, and clearing out the ash was not fun for either of us. We moved here, where the previous owners had put in a Stanley range (oil fired). If you used the ovens, the room would be far too hot to even be in, it cost a fortune to run, and of course for the summer, you had to have a electric cooker sitting beside it anyway. It also cost a fortune in servicing and repair. We took it out, put in a new fancy boiler which gives you hot water whenever you need it, and we cut our oil bill in half. Having said that, it doesn't cost 50% less because the price of oil keeps going up!
