DISHWASHERS SUCK ELECTRICITY (literally)
So I've put together a small off grid system, just enough to run our main air conditioner in the hot days ahead. Rather than leave it sitting idle rn I've started running various things off it like the dishwasher and was shocked at how much energy that uses according to the inverter. Initially it's less than 100W but once it starts heating the water it jumps up to nearly 2,000W
In some countries they're connected to the HW system instead and don't have a heating element but Australia follows the European design where dishwashers heat the water themselves (because we also have 240V mains?). Since we enjoy FREE hot water courtesy of our Solahart I'm wondering why our dishwater can't be connected to that instead.
Our plumber said it's "not good practice" because (untempered) HW might be hot enough damage the DW but by law household HWS have to be limited to 50° and the manual says up-to 60° is ok. So I'm stumped why we all pay this penalty every time we run the DW 🤔 Anyone tried connecting to the HWS instead?
Edit corrected typo' in tempering valve setting
