I changed out both elements in my electrc water back in late August. Had to change the bottom one out again today.

        You are technically right that the water heater softens the water a bit by precipitating the minerals around the heating element and thereby removing them from the water. But that is energy inefficient and expensive, since you normally don’t use a water heater to soften your water but rather to get warm water. So putting another system in front of the heater that softens it first is better than replacing the heat element every so often.

        You can’t filter out ions of calcium like that. A huge reverse osmosis system for the entire home would be prohibitively expensive. I used to live in an area with very hard water and everyone had water softeners. You only need to buy the salt every few months and it’s not too bad. RO filters were only connected to a tap on the side of the sink in the kitchen - those membranes aren’t cheap.

        The sacrificial anode is there to protect the steel tank. It lasts a long time. This is a hard water problem as everyone else is saying, and a water softener would solve the issue.

        *Edit: check the very bottom of your tank since you have the elements out. It most likely has a pile of calcium and other minerals sitting on the bottom.

      Anodes protect against corrosion. They don’t do anything for hard water scale.

        That’s not entirely true: sacrificial anodes attract and collect calcium and magnesium as well as preventing rust.

          The prevention of rust does slow scale accumulation because rust is a rough porous surface that scale likes to stick to. But other than that (anodes also are rough porous surfaces) I’m not aware of any way they actively reduce it. Maybe the electronic ones, but that’s out of my wheelhouse (and they aren’t sacrificial).

    I’m guessing the inside of your tank looks just like this and swapping new heating elements in isn’t going to fix that. Maybe try flushing it out first?

    That’s why you should have a gas water heater if you have hard water. Electric units get wrecked by scale, regardless of a water softener.

        Maybe with that attitude. You are willing to swap a heating element but not running a gas line? It ain’t shit but playing with black pipe and dope like a white girl with daddy issues.

          Those are two different skill sets, just because you think swapping a heating element is hard doesn’t mean everyone else does

      But it’s a greenhouse gases contributor - electric is better. Check that anode commented below.

        Electric ain’t better if you have to replace it constantly. Think of the emissions to produce these parts.

          The emissions to produce a single heating element off a factory line are probably a lot smaller than keeping a jug of water in your house hot by burning natural gas off and on all day every day forever

            And that’s why you get an on demand unit. In either case, heating water in a jug over and over just so it might be hot hen you need it is not a great idea.

              I agree. I use very little gas to heat my water for my hydronic system and the tap. I replaced an old oil hydronic heater and traditional electric water heater with a natural gas combi boiler that does both home heat and hot water. My utility bills went through the floor, and over the whole year I put a fraction of the CO2 into the atmosphere than I did in just a winter of the old oil furnace.

            And so we come to the eventual argument. An electric water heater is going to keep a jug of water in your house hot by running off and on all day forever. Where did that electricity come from?

              In my case, a mix of fossil fuel and renewable resources that on the whole are significantly less carbon-intensive per unit of energy than straight up burning methane in my house

                I wish we had European style water heaters at the tap. But that’s not safe. You should see what I find in hospital infrastructure.
