I guess it depends on whether you're more concerned about water efficiency or energy efficiency. If you're OK with not reusing the water, the building's water heater (especially in a multi-unit dwelling) is going to be larger and thus more energy efficient (also possibly slower, providing large quantities by dint of its tank) than the smaller heating element in a dishwasher. And you can just trickle a little bit in throughout the cycle to keep it hot.
- refurb 8y agoDefinitely. Heating water with an electric element isn't all that efficient at all compared to say a gas water heater.
- gambiting 8y agoI think you got the terms mixed up here - electric heating is far more efficient(for every 1kWh of energy used, almost all of it goes into heating water) than using gas, but electricity is also more expensive so even taking account lower efficiency of gas heating it's usually cheaper anyway.
