The following laundry appliance features will have different levels of importance to you depending on your needs and circumstances.
Spin Speed: The faster the spin speed, the more dry your clothes will come out at the end of the wash. Spin speeds vary from 800rpm to 1800rpm, and faster spin models generally cost more money.
Capacity: The larger the capacity of the machine, the more clothes you can wash effectively during one wash cycle. The standard capacity is between 5kg and 7kg and this will be sufficient for most households. Larger loads are catered for by 8kg and larger load capacities.
Energy Ratings: The Energy Rating label enables you to compare the energy efficiency of each appliance.
Water Ratings: The Water Rating label enables you to compare the water efficiency of each appliance.
Programmes: Quality is key here, and not necessarily quantity. You need to ensure that the machine you choose incorporates all the programmes you require, and these can vary from woolen and special care washes to quick wash or sensor wash programmes. Eerybody's needs are different.
Tumble Dryers: First establish the capacity you will need: manufacturers usually offer between 3.5Kg and 7kg loads. The method of venting is an important and there are two methods: some models are vented outside, while others condense the air within the machine (which means no more condensation in the laundry!)
Washer Dryers: All washer dryers have separate Energy Ratings for their washing and drying functions, and their drying capacity is usually half of the wash capacity. While washer dryers will save you space, it will cost you time (i.e. you can't dry a load whilst washing a new one). Where space allows, it is always preferable to have a separate washer and dryer for this reason.
