I have no idea what the efficiency of my oil boiler is. Makes it pretty tough to use this chart. :(

A little too much Werner Von Braun going on here!

It's pretty simple in my case.

This season, coal works out to be less than1/2 the cost of oil for the same heat in the house.

To me, Yanche carries that designation. I couldn't walk in his shoes.

But aren't those that have a powered exhaust of some sort and mix room air for the lower exhaust temp? I don't know if this could be compared to coal.. :? Pardon if I'm confused :lol:

Whewww! I think its about time somebody took the coal nuggets out of his underwear and loosened them up a little bit. Is it time to take a ride on the coal fired hot air balloon?

Sorry, I think its bullshit that a moderator shows up just to make us feel like idiots for discussing things like this.. Pretty classy.. :|

I wasn't talking about you. ;)

Really? I think that it proves the point that we are all trying to make about coal. It's cheaper than oil. When I bought this house years ago and told people I burned coal they looked at me as though I was a moron. Not any more.

This is proving to be, like other threads that Larry has started, a nice, lively round-table on coal burning. Taking cheap shots at him and his intelligence is uncalled for and certainly not in the spirit of this site. When he designs the first 100% efficient coal appliance that heats a wind tunnel on 5 pounds a day we're all going to line up to buy one.

starting burning on Oct 1st this year almost 2 months earlier than i have in past. started with 8600#'s coal, was down to approx last 1000#'s of caol, 2 weeks ago, got another 6000#'s.. Temps this winter have been a lot lower for past 2 months, near 0* or lower in AM. with day highs averaging near10- 15* thru same period. Burned up about approx. one and three quarters tons of coal in same time period. leave heat set at 70* in all of rooms of house. Still cheaper than oil by half or better. We're warmer than i would have if using oil, would been set at 65* when not home or sleeping, 68* when up in evenings early morning or weekends home.

All of this stuff was exhaustively researched over a Century ago. I guess it's a good thing that there are people who want to reinvent the wheel, because; the first wheel inventing has been forgotten or the results found then are refused to be believed.
I think it is a little bit of both.
It was found that base burners are much more efficient than boilers or furnaces,
The average base burner efficiency was found to be around 80%. That's not the high end, that's the average.
The average coal stove of any kind was found to be in the 70% range.
Boilers and hot air furnaces were in the 50 to 60 percent range.
I know it is hard for the lovers of gadgets and the tinkerers to accept it, but; that's the way it is. There's always room for gadget hounds and their endless fascination with auxiliary gizmos.
I'm not knocking it. Everybody needs a hobby.
I or franco or anybody else can put up stuff all day about the obvious efficiency of these old stoves and it still won't be believed or accepted by the gizmo groupies. I've long since discovered this and so be it.
To each his own.

Most are not lucky enough to have the base burner perspective.........Outstanding engineering, execution and life expectancy.......no CAD, No CNC........bright minds creating lasting beauty and functionality. Nothing else to say. Well, we sure could use their abilities again in our 'Wally World' lives. :idea:

Well, i have no clue as to the % efficiency of our OWB ,it burns lots of wood,but oil & or propain would cost lots more but would give me % more time to follow threads on % this & % that,% % = mind boggling %. Now when we go to coal from wood $$ spent % won't change drastically , but th % of time spent on fuel supply will be %% easier,just my simple minded way to explain my savings %% :lol:
