Awesome. I so wanted the Sanco2 but the price put it out of reach, and we don’t use enough hot water toake the payback remotely reasonable. For anyone else reading, it’s an R744 (CO2) refrigerant system that’s massively better for the environment than HFCs (and HFOs) as well.
Comment on Heat-pump water heaters are a winner for the climate — and your wallet

I have a Sanco2 heat pump water heater. The heat pump is located outside the house, with the tank in the basement. It is so absurdly efficient that I thought I was measuring the power draw wrong. Its expensive up front, but a big fat govt tax credit sure helped and the monthly power cost is about the same as my coffee maker.
The tank inside is 83 gallons. I can run the dishwasher, two showers, and anything else I can imagine and it handles it like a champ. The heat pump heats the water so fast that it refills it in minutes, not hours.
And since there’s no element or anything in the tank, there’s virtually nothing to break or fix in it.

I’ve never heard of this brand before but I love that the heat pump is on the outside of the house.

They forgot the best part. That model uses CO2 (it’s in the name), instead of older HFC (or very ancient CFC) based refrigerants.

Oh, you Americans with your hot-water dishwashers! ❤️

Wait, are hot water dish washers not a thing outside the US?
Taringano@lemm.ee 7 months ago
I think it’s everywhere but in the US the water comes already hot, in Europe the dishwasher heats it up from the regular cold water.
Squizzy@lemmy.world 7 months ago
Yeah the hot water way seems better.
Zron@lemmy.world 7 months ago
That seems way less efficient and more prone to issue than just having a central appliance that’s responsible for making hot water.

Dump a kettle of boiling water in the dishwasher before you start the cycle.

This is crazy to me. How do the dishwashers in US heat the water up hot enough to clean effectively? Our dishwashers heat the water up past scolding, really helps cleaning.

Every dishwasher I’ve used in the United States has a built-in heating element. Mine has a steam sanitize function and gets quite hot.
However, it is conventional here to plumb the dishwasher to the hot water line, and it is my understanding that the dishwasher is designed to assume the water is hot and doesn’t try to heat it from cold during the first rinse.
I’ve found that running some water from my kitchen sink to prime the hot line with hot water makes the dishwasher more effective. I use that water for plants, or I keep it in a jug and pour it into a load of laundry in the winter.

There’s a heating coil in the bottom of the unit. Water floods in and sits for a short while while reaching temperature.

They really help conserve water compared to hand-washing. Important with the many relatively dry arid places in the south and west of the US.

Oh yeah, I’m with you that dishwashers conserve water. I was making a playful remark that in Europe, the dishwasher takes cold water and heats it up itself, not arguing for or against dishwashers as a concept.
