Our new house has an oil-fired #Rayburn that does heating, hot water (can be heated separately by immersion) and cooking (have gas hob, microwave and electric oven also). Have just been using Rayburn for hot water so far but will need heating soon and I’d like to try cooking with it. Does anyone have any tips?

I know they aren’t cheap to run (also oil!) and will be looking at other options so not looking for alternative suggestions rn - want to live with it for a season but use it best. Tx
