Good point, but you could also factor in those that go through the splitting
and stacking don't require a $500 per year gym membership ;-)

Then there is that whole funding of terrorist nations thing with the oil and
gas......

Here's my setup: a 12 year old forced hot water oil boiler, with a gas
conversion burner, and connected to that is a 40 gallon indirect fired
water heater. We've been heating our house with a wood stove for the
last two years, so all the boiler does is heat our hot water and serve
as a backup for our wood stove.

When the plumber installed the water heater, he turned the low point
on the boiler all the way down. The boiler kicks on when the water in
the boiler goes below around 65 F degrees. High point is 160. Water
heater is set at 127 degrees F, which gives us 120 degree water at the
faucet. The heat loss for the water heater is 1/2 degree per hour.

The water heater calls for heat when the temp goes 10 degrees below
the set point. So the boiler may sit for hours without calling for
heat, so the boiler temp goes down to room temperature again. So for
our hot water, the boiler is heating its own 6 to 8 gallons of
"boiler" water to 160 degrees in order to heat the water in the water
heater. That seems like a lot of energy going in to heat the boiler
up every time we draw hot water.

To remedy this, I installed a timer that turns on the water heater
once a day for an hour. The 40 gallons of hot water gets us through
the day (so far, but I just installed the timer last weekend). My
friend says this won't save any energy, because warming up the hot
water tank from a low temperature will take more energy than heating
it up throughout the day, where the temp differential is lower.

A drawback is that the hot water controls will be turned on daily
instead of being left on constantly, which may reduce its life
somewhat. It's got a solid state control unit with a LED control
panel.

I could get a device that measures the amount of time my boiler kicks
on to find out which way is more efficient, but before I shell out for
that, I thought I'd see if anyone had any ideas. Anyone have any
guesses which way is better? Thanks!

I would install a standard water tank since you never run the boiler
for heat.........

Nows here a great question that may cause you grief

How many hours a year do you spewnd cutting hauling stacking splitting
the wood for your stove? add bought firewood if you do that.

Now compare your cost of work to the cost of fuel for your regular
boiler.

even with free firewood every person I EVER asked isnt really saving
much money.

So please supply your numbers
