I am dying of heat due to the Aga. Even the DC, who want me to have the heating on 20 degrees in winter (14 degrees is my optimum temperature, as I am menopausal) want me to switch the Aga off. But we have no space for an extra oven, even if I wanted to re-model the kitchen (which I don't). A small worktop oven and hob thingy are the compromise. But I am baffled and don't want to spend much . Any advice, please?
