To test the heat loss from the sides of your water heater tape a piece of insulation, about a square foot, on it. After an hour or so stick your hand in between the insulation and the tank. You'll be surprised how warm it is. That's standby heat loss.Yes, that is where the small losses come from. Hot water heaters are not perfectly insulated, so they lose a little heat.
It's pretty trivial. If I touch my hot water heater, it does not feel warm. The hot water pipe leaving the heater is the main source of heat loss.
Heat pump water heaters do exactly the same thing, and that is what this thread is about.

Trivial losses X 130 million water heaters.It's irrelevant!
Biden's proposal does not change that in any way. Please try to follow along.
What does adding a heat pump to a central hot water tank have to do with that? Absolutely nothing.
They are over 90% efficient. Please quit complaining about trivial heat losses. It's nothing.
As I mentioned more than once, Biden's proposed rule does nothing to change the heat losses from central hot water heaters, so it's a bit puzzling why you two keep trying to change the subject to the benefits of instant heaters versus central conventional ones.Trivial losses X 130 million water heaters.
Just fleshing out the subject. Bidens proposals won't affect anyone until the new rules are in place and people replace their water heaters. Until then all sorts of things can happen. Let's talk about that.As I mentioned more than once, Biden's proposed rule does nothing to change the heat losses from central hot water heaters, so it's a bit puzzling why you two keep trying to change the subject to the benefits of instant heaters versus central conventional ones.
The OP mentioned that water heating accounts for about 13% of residential consumption. DOE says electric hot water heaters are over 90% efficient. So, we are talking about 1% of energy use. 1%. And Biden's rule does not reduce these losses at all (so not sure what you are talking about - it's irrelevant, but you are apparently a keyboard warrior and choose to ignore this because you want everyone to switch to tankless heaters to save 1% on their electric bill at a cost of ~$3000).
Goodbye.
Yes and no....very energy consumptive during supply.Tankless is the way to go.
If you don't have a tankless water heater, you are behind the curve.
First they came for your lightbulbs, now they come for your water heaters. Oh the humanity!
Tankless is the way to go.
From the sounds of it, most of you are already miserable.It's all about making our lives just a bit more miserable, like boiling a frog slowly in water.

Efficiency and standby losses are two different things.It's irrelevant!

How much does a tankless water heater cost, especially when I have a perfectly good electric water heater in my home?If you don't have a tankless water heater, you are behind the curve.

You did not read his reply. He said electric!They use a lot of gas keeping 60 gallons of water over 120 degrees, 24 hours a day. My water heater only heats the water when I turn on the tap, the rest of the time, no natural gas or electricity is spent keeping a tank of water hot.
I have very hard water and have never had a water softener. My tankless works amazingly well, and if I want to take a shower for an hour, I'll never run out of hot water,
Adding a heat pump as will be required does not affect standby loses. The heat pump heats the tank water along with the electrical heaters.Efficiency and standby losses are two different things.
