Washing machines with dual water supply
Washing machines with dual water supply (including a hot water supply) are an innovative solution that offers greater flexibility and energy savings. Unlike traditional washing machines, these models have two water inlets: one for cold and one for hot water. This feature allows you to use pre-heated water from solar water heaters or other heating systems, reducing electricity consumption. Indicative models on the Greek market
How They Work
The basic operating principle is simple:
- Cold water supply: Used as in any washing machine, mainly for programs that require low temperatures.
- Hot water supply: Draws hot water from an external source (e.g., solar water heater) for programs that require high temperatures.
The washing machine features an advanced control unit (controller) which manages the mixing of water from the two supplies. This “brain” ensures that the temperature of the water entering the drum is precise, offering optimal washing results without waste.

Benefits
- Energy savings By using hot water from solar energy or other sources, you decrease the need for electric water heating, leading to significant operating cost reductions.
- Eco-friendliness By lowering electricity consumption, these washing machines help reduce the household’s carbon footprint.
- Better Cleaning Performance Hot water helps dissolve detergents better and remove stubborn stains.
- Easy Connection Most models allow for flexible connection to various hot water sources without the need for complex modifications.
Drawbacks
- Initial Cost Washing machines with dual water inlets are usually more expensive than traditional models.
- Installation Requirements A hot water connection requires proper preparation and possibly additional expenses for plumbing installations.
- Limited Availability In the market, models with dual water supply are not yet as widespread as conventional ones.
Important Note on Performance
For a dual supply washing machine to operate effectively, it’s important for the hot water source to be located close to the washing machine. If the distance is large, heat losses during water transfer may lower performance and negate the energy savings benefits.
Is It Right for You?
If you have a solar water heater or another heating system that provides hot water, dual water supply washing machines can be an excellent investment. They save money and energy while also being more environmentally friendly. However, before purchasing, consider your needs, available budget, the distance from the hot water source, and your household’s plumbing setup.
Conclusion
Washing machines with dual water supply are a modern choice for those seeking efficiency and savings. Although the initial investment may be higher, the energy savings, optimal washing performance, and eco-friendliness make them an attractive option for modern households.
