Lol I know people with a well and they never even knew they had a well they never had to touch it and never thought about it was the funniest shit when their pump went out and were confused why they didn’t have water
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
Cool, when those heating elements are shipped over here via bunker fuel. I’ll bet a boatload of those coming over is more emissions than running a NG burner for a decade
Except it’s not a boat transporting one heating element, but thousands upon thousands of other things. To accurately quantify emissions you’ll need to divide the ship’s total emissions by the # of products on board, likely making transport emissions from a single heating element negligible and easily surpassed by burning methane in your house constantly 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?
A lot of the electricity probably came from burning natural gas at the power plant, and then some of that (~5%) gets lost in transmission. If we assume the natural gas plant is 60% efficient at turning gas into electricity, then an electric heating element in a hot water tank at your house would be about 55% efficient.
A typical gas furnace is about 80% efficient at turning gas into hot fluid, and a good one can reach 95% efficiency.
Depending on the fuel mix of your local grid, there’s a good chance that burning natural gas at home will result in less pollution than using electric resistance heaters, either for heating water or the air inside your home during winter. Places like Washington state that generate most of their electricity from hydroelectric power plants will be exceptions.
However, heat pumps can be higher than 100% efficiency. They don’t use electricity to generate heat, they just move heat from one place to another. You’ll produce fewer emissions overall by using an HVAC heat pump to heat your house, and a heat pump water tank for hot water. Even if you live in a place like Canada, you can reduce emissions by installing a dual-fuel system that will use electricity to run the heat pump weather permitting, and fall back to using gas when the outdoor temperature goes too far negative.
Using heat pumps to move heat from outside, to inside your house, to inside your hot water tank is more efficient than using gas to heat your home and water, even when the electricity to run the heat pump is generated by burning natural gas.
Please stop the climate denier arguments. Even if it was a gas power plant, it would be still more efficient than your little home gas heater and this gap gets wider and wider when we add more and more renewables to the energy mix.
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
Thanks for sharing - this is wicked. It’s strange that it has taken so long, but it’s very cool that we’re possibly seeing a return to wind power, and this looks WILD to boot.
But it’s a greenhouse gases contributor - electric is better. Check that anode commented below.
Anodes protect against corrosion. They don’t do anything for hard water scale.
Looks like some types can help with hard water too

The active electronic ones may. I’ll admit I don’t know a lot about those.
Heat pump would be best
Probably still would get issues with hard water though. OP needs a softener.
Honestly, water this hard should be fixed at the water treatment facility that provides his water. This much after just a couple of months is insane.
OP could have a well.
I’d think a well owner would be a bit more informed about water purification.
Lol I know people with a well and they never even knew they had a well they never had to touch it and never thought about it was the funniest shit when their pump went out and were confused why they didn’t have water
You would think that…
Electric ain’t better if you have to replace it constantly. Think of the emissions to produce these parts.

I don’t own a home but if I ever do I would love to put in a heat pump and solar panels. Great detailed response.

I bet you like nuclear.
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.
Oh I used to work at a hospital that was built in the 60s and know full well what sort of asbestos-laden Frankenstein’s monster they become over time
I’ll quit using gas the day shipping vessels go back to being fucking wind powered
