We have integrated appliances in our kitchen. our old tumbledryer was vented but you cannot get intergrated vented tumbledryers anymore, only these heatpump ones. Sold as being more economical but when you have to put the same load on 3 times or more to get it dry it clearly cant be. Having young children means we need to be able to get items washed and dryed asap, especially bedding, and we cant do that anymore
