Ayuh,....    I pulled domestic hot water off mine, almost the entire 1st summer I ran it,.....

Unless you use lottsa hot water ,,,,i worked it out,, to a wash for me.
Running the pump and fan on the OWB = hot water electricity for us.
Gotta get the wife to shower more,,,,, to break even,,, no savings

Ayuh,...    Agreed, sorta,....      1st summer, I'd throw in 3 or 5 blocks a day for hot water,....

2nd year, I went back to the water heater in my oil boiler,....
275 gallons of oil, for that summer,...  back when oil was "Only" $2.50 or so a gallon,....
Never again,.....   

An electric water heater, adds nearly $100, a month, so that ain't comin' back into this house either,....

I settled on a propane fired on-demand unit, cheap chinese junk, but works, 'n burns very little gas,....

My electric water heater costs me $50 per month.

We don't use much hot water ..
That's the difference.
My bill is roughly the same when shut down ,no pump, or fan, running.

Our water is heated electrically when boiler is shut down

We do run an air exchanger in the winter also .

Total Electric bill is $179 September and $172 February,,and pretty much 170'$$ all year.
We don't use the A/C,, it almost always cools down at night
I got the bills in front of me .

The short and long is....... Electric energy for OWB pump ,fan, and the house, fresh air, exchanger = Electric energy to heat the hot water.
or real close.......
Still wouldn't change a thing

Everyone's savings will be different.

Before going on a budget plan with our provider I never really could tell a difference in the electric bill from the boiler, have nat gas for backup heat and hot water, pretty much runs the minimum thru the winter for gas. My electric usage is also somewhat skewed as the farm also runs off the same meter as the house, lights in the barns, electric fencer, block heaters on tractors or straight trucks or semi's.  The big stuff is all on the three phase like the air compressor, grain dryer, aeration fans on the bins, all the augers, grain leg, pneumatic grain mover, in the shop the big wire welder, plasma cutter, bridgeport and lathe are also three phase.

Pay about $270 a month year round for single phase electric. Starting to change out lights in the shop for LED 48" fixtures.

How much a kwh do you pay ??

We got peak$$ $ mid peak $$ and off peak$
Stupid,, smart metre.
We got all kinds a goofy charges on our bills,,,, gotta be an accountant to figure it out

Last time I checked was around 11 or 12 cents a kilowatt.

My electric water heater costs me $50 per month.

Mine too.  It's not worth running the boiler all summer to save $50 a month.  I sure do love all the free hot water when the boiler is going!  If I decide to hook my hot tub up to the boiler it might be a different story.  I don't have it going yet so I don't know what it costs to run in the summer.

Heating my DHW saves me about $75 a month on my electric bill. A wife, two teenage kids, and a 5 year old that likes his bathtub full so he can play in it, uses a lot of hot water. 

I have most of my wood delivered split for $100 dollars a dump trailer load.  A load comes out to just shy of a full cord. The way I look at it, heating my DHW with the boiler (@12 months x $75 = $900) almost pays for enough wood to heat my house all winter for free.

I don't pay for wood so I don't shut down. I just bypass the furnace coil. Love the hot water.
