I just want everything with a heating element to use a heat pump instead. Electric heating elements are so horribly inefficient and wasteful in comparison.
I have a ventless heat pump combo washer/dryer. It takes up half the space that two machines would, plugs into a regular 110V outlet, gets HOT (way hotter than I expected a heat pump has any right to achieve), drains all its drying water into the drain, vents none of my indoor air outside, doesn't require changing laundry from one machine to the other. Practically and mechanically it seems brilliant and I can't imagine why I would ever buy a traditional machine ever again. Except...
It's chock full of horrible apps and shit that I'll never use. It's way too "smart", and those "smarts" are not there for my benefit. After a month or two it finally gave up trying to pester me to connect it to a network and install the app, which I'll never, ever do. It's never going to see an update or new firmware if I can help it, but I'm afraid that if/when it ever breaks, I'll have no choice. I know it's going to do things like eventually refuse to work until the computer has been "updated" to be "compatible" with new parts. And it's not even just that it's going to be expensive. It's that I don't trust it, and I don't trust it to remain functional in the future, even if there are parts, that they won't let me install the parts, or will require me to agree to play by their "rules" before I can.
Right to repair needs to be a thing, and people need to be able to break the ridiculous amount of both legal and practical control these manufacturers have over their devices after they've left the factory. We cannot and should not trust the manufacturers to support it. We need to allow independent repair.
I thought electric heaters were 100% efficient? All the electricity you put into it becomes heat yeah?
Yea but heat pumps have a coefficient of performance of greater than 1 cause you're moving heat instead of generating it.
Yeah my heat pump is something like 2000% efficient. It can cheat because it doesn’t convert electricity into heat, it uses electricity to move heat from the outside to the inside (or vice versa).
So, 1 kwh electric energy to an electric heater produces 1 kwh of heating energy.
So to give you an idea how a heatpump would do: looking at my heat pump's data registers right now, it says it used 3.6 kwh electric energy in the last hour to produce 12.7 kwh heating energy (air to water).
