Have just bought house with small oil aga (a conversion from solid fuel). Had it serviced and all was fine but we put it down on low and then when we turned it up it just didn't seem to be getting any hotter. I thought it was going out so I switched it off. Not sure whether I did the right thing! Should it relight easily? How long does yours take to get to optimum temperature? Has the strong wind got anyhting to do with it??
