The configuration of washing machines can vary depending on the model and region, but in most cases, washing machines are connected to both the hot and cold water supply. However, the exact setup may differ based on the design and features of the washing machine and the plumbing infrastructure of the building.
Traditionally, washing machines are designed to connect to both hot and cold water supplies, allowing users to choose between hot, warm, and cold water settings for different wash cycles. This is especially useful for laundry that requires specific temperature settings, such as bedding or heavily soiled items.
In some cases, washing machines may also have a built-in water heater, allowing them to heat the cold water themselves if a hot water supply is not available or not connected. This feature is more common in certain regions where hot water lines may not be easily accessible.
However, in recent years, there has been a trend towards more energy-efficient washing machines that primarily rely on cold water for most wash cycles. These machines may have a single cold water connection, and the water temperature is adjusted internally using heating elements if warm or hot water is required.
When installing or using a washing machine, it's essential to consult the manufacturer's instructions or follow the guidance provided by a professional plumber to ensure it is connected correctly to the appropriate water supply and that it functions efficiently and safely.
