Pros of Built-in Water Heater Washing Machines

Reduced Drying Times

Washing machines with built-in water heaters provide some important perks. They clean clothes thoroughly, and even help to save time and money. The following are a few key reasons you may want to opt for a washing machine with a built-in water heater.

  • Reduced Drying Times - Because items are already warm from the wash cycle, throwing them straight into the dryer will reduce cycle times. Less effort from the dryer is required to evaporate the water. So you'll save electricity and thus incur lower bills.
  • Hot Water is Ideal for Heavily-Soiled Items - While many garments are best washed in cold water, some laundry items, and clothing soiled with certain types of stains are better when washed in hot water. For example, many undergarments, socks, and workout clothing need the superior cleaning power of hot water to remove dirt and odors. Dirt and mud, tomato sauce, egg, grease and oil-based products, and many other types of stains wash out much more easily with hot water.
  • Less Detergent is Needed for Some Cycles - Detergent dissolves more easily in hot water. That means you won't have to add as much. So you'll save money on detergent in the long run with a washing machine with built-in heater.

Cons of Built-in Water Heater Washing Machines

Repairs can be More Costly

For many homes, a washer with a built-in water heater solves problems. Just remember to consider the following points to make certain this type of appliance is the right solution for your laundry needs and the space where the washer will be placed.

  • This Feature Can Make the Washer Heavier - The additional component of a water heater built into a washer can make the washer both bigger and heavier. But you can still enjoy the benefits of a built-in water heater, if you have smaller loads, by opting for a compact model.
  • Repairs Can Be More Costly - Water heaters can be expensive to replace. That can translate to a higher-than-average cost to repair a washer which includes a water heater. The risk doesn't mean you shouldn't choose this type of washer. It's simply something to keep in mind. If you prefer DIY repair, you should note whether any physical issues with the washer you're considering may impede installation and troubleshooting.
  • Additional Noise May Be Created - Besides basic operating noises of a washing machine cycle, the water heater can make its own series of noises when active. That fact can make these appliances louder in general. This is simply something to consider if the washer will be placed in an area where the additional noise may cause disruption.
