First of all,
I'm not the 5 post wonder you are.
Secondly, I moderate/admin plumbing forums across the internet, but I just started plumbing last friday.
Second, you don't "grasp" sediment that lines the bottom of a water heater on gas models
you don't "grasp" electric water heaters that can have sediment issues that reach the lower element which is the worker bee of the tank in producing hot water, that when it is submerged in sediment like the picture above shows...the energy guide is wasted print on the heater.
Run with Bison,
Have you never seen an electric water heater element pulled out of an older, sometimes relatively newer water heater at times when a layer of sediment bakes itself to the element, and you hear what sounds like bacon sizzling when the upper thermostat calls for action and you know your water heater is operating?
Are we on the same planet or did I make a wrong turn at Mars today.
Do you think that efficiency isn't lost when buildup is on the elements OR in the bottom of the tank?
DO you think Master Plumber Mark shoved oatmeal in that water heater to make up stories?
Efficiency loss is not necessarily the same as poor recovery or lost working volume.
Are you serious?
So, when a tank's capacity is lost due to mineral buildup, and the conversion is.....wait.
You fill in the blank. You tell me what the conversion is for capacity against ready to use hot water, figure out the # of gallons and then tell me what's the factor used in consideration for doing conversions from gas to electric, electric to gas and what needs to be increased or decreased when doing so.
I'm still scratching my head over your electric water heater claim... How again is the electrical efficiency lost? Sure the elements will burn out and quit working, but nearly all of it from beginning to end is going into the tank because it is a resistance heater. The tank can be full of sediment but the heat is still going into the water. The only other place it has to go is surface losses...which are not changing much.
Did the picture above your post ever make you think that sediment can bury the bottom element...???
Never heard of scale/lime buildup on an element?
You mentioned burn out and quit working...wouldn't that be a dead end statement in reference to knowing that it's going to be instantly replaced to make it operable? Hello?
"The tank can be full of sediment but the heat is still going into the water"
What happens to thermal transfer/dissipation when someone cooks food and beans burn in the bottom of a pot? It traps it, interrupts the cycle of heat rising to the top like all water heaters are designed to do...
that's why cold water enters the tank through the dip tube,
that's why electric water heaters operate by the lower element to heat the incoming cold that rises to the top for the ready to use hot water,
the top element is only for sustaining ready to use hot water when the heater has been inactive for a period of time.
The statements you're making are easy to blow holes through with how much you don't know about the operation of a water heater.
"But my dad works on computers, and he's got tools. We can use his tools and fix things."
If you're going to dance with me, at least dance to the same song with me.
Now I have a reason to use my camera more effectively so the proof is in the pudding to reference what I already know.
You're going to get charged for the ear plugs for every water heater I cut open for the visuals so this "unknown" by years of knowledge comes out and people can point and giggle at the empty statements I just filled for you.
It almost sharpens the pencil for me, it really does when reality and perception get mauled over by someone who can type and argue. I'll be waiting for your response on what you should know in the paragraph above to see if I should stop.
No, I can't do that, I got pictures coming! Whoops, here's one with a little more of that non-efficiency rust buildup:
