Have had a new on on standby for a few years now, but am going to have to install it here shortly to facilitate a remodeling project I want to do.
Must not be installed right, I had a leak from the well pump pipe and all the water that leaked out of that went straight into the sump, so that is not a problem.
One of the (many) reasons I moved out of NE.
This and several other replies assume that "heat with electricity" means electric resistance heating.
A heat pump (which is also electric) is more than 100% efficient, in the sense that the thermal energy delivered to the interior is greater than the electrical energy used to pump the heat. This applies to an interior temperature of about 70F and exterior temperature down to about 15F. With a greater temperature difference (exterior below 15F) the heat pump efficiency drops below 100% and you are better off switching to resistance -- as some heat pumps do automatically.

Well, I don't know. Decades ago I knew the price of everything in 6-packs.
Many economists use Big Macs as the measure of value.
Harry, that famous "Hollywood education" of yours is showing through again. The require output of a water heater is HOT WATER.
Proving, once again, that you're an idiot.
They may, now, with the housing market dead but in general, no. Jobs move, and that trend is not going to go the other way.
In that sense, everything is 100% efficient, because mass-energy is always conserved.
This viewpoint however is not particularly useful to someone trying to figure out how to heat a house.
For a discussion of efficiency to be meaningful, you have to say what you are measuring with respect to. Absolutes are not useful.

No it is not. It's an agreed upon measurement of inputs and desired outputs. Just stating your number is not scientific at all.
Then why did you state that electric water heaters are 100% efficient?
Which you've demonstrated is beyond your grasp.
e:
electric water heaters are 100% efficent, except for their tiny standby losses.
Too bad a BTU of electric heat isnt as chaep as a BTU of gas heat, electricity to heat costs a fortune:(
Those "tiny standby losses" are a function of the amount of water used, so your statement is nonsense.
That's certainly dependent on location and why heat pumps are common.

e:
rote:
electric tanks are heavily insulated and lose very little to stand by losses.
so 99% is that good enough for you?
no put the energy label on all new heaters gives a efficency number. which for electric is always very high
T
No you can't. Eff == Eout/Ein, or in this case Eout/(Eout + Eloss). Eloss is a constant but Eout is variable with the quantity of water used, but can never equal 100% (Eloss is finite).
T
It's useful as a comparison with like units. Otherwise it's less meaningful.

You Brits really are stupid.

Hi, Mr Pot.
No, you don't think; too stupid.
