The video explains that dishwashers sold in 110V countries often has a hot water connection as it's too slow heating water off a 110V/10A circuit so it is more efficent to utilise the hot water pipes. However we live in NZ, a 230V country so we get dishwashers that can heat water from cold fine off a 230V/10A circuit so no need for a hot water connection.
- seanmcdirmid 1y agoModern heat pump dishwashers will heat water on 110V just fine, but you are looking at 3 hour wash/dry times anyways. My Bosch isn’t connected to hot water and even has a sanitize mode.
- sgerenser 11mo agoBosch dishwashers have something they call a “heat pump” that is a water pump that also heats the water with resistance heat. It’s not any more efficient than the normal heating coils in every other dishwasher, and it isn’t a “heat pump” that uses a refrigeration cycle (as one would use to e.g. heat their house).
- seanmcdirmid 11mo agoHeat exchangers are used for drying, they don't have heating coils for drying.
- sgerenser 11mo agoWe’re talking about heating the water, not drying. The discussion started with regards to energy used to heat water vs. using water from the hot water tap.
