Electric hot water tanks are a thing. So are electric tankless systems.
I'm aware but I haven't heard people's experiences with them. I ask because I'm shopping for water heating right now and debating the expense of getting 240 run to the water heater for a heat pump.
Electric tankless sounds impossible (yes, I know they exist, I just mean they don't sound like something that should be able to), since the amount of BTUs required to run a gas tankless at peak is absolutely nuts -- tankless gas water-heaters run on 3/4" pipe instead of the normal 1/2" since they need to have so much burst heat. That doesn't sound possible for electric.
A whole house model will need a 100A circuit to itself. You could install small units in each location that needs hot water but that is also expensive.
Holy crap like 24000W of juice on tap. That is not screwing around. Awesome. A neat option but sounds like something for new builds not retrofitting an older home.
If you have 200a service to your house then it might be an option but lots of houses (including my own) do not have the capacity.
I really need to upgrade to 200a or get gas heating as my 100a is woefully inadequate when temps are below freezing like now.
If you already haven't, do check out Technology Connections videos on electrifying, he covers old home challenges quite a bit.
I was reminded of him because he talks about the possibility of making a 100A circuitry workout with some smart switching
Yeah I love his videos but I hadn't seen anything about the whole home issue of "omg this is way more power hosue-wide".
The idea of smart switching sounds neat - that would basically mean "you can't run your dryer and have hot water and charge your car at the same time", right? But, like, in an automated way not just "it throws the breaker".
Pretty much yes, a contraption to make sure you don't surpass your amps without worrying about having it all plugged in
