oil and hard coal combination stokers

PostBy: fix it On: Fri Feb 19, 2010 2:25 pm

I have a 25 year old K-8 keystoker. I burn 16 tons of hard coal a year. I heat my domestic hot water with coal. As you can imagine I need a break from ashes and coal. I am interested in buying a combination hard coal and oil stoker. Does anyone out there have one and how do you like it?

I believe your Keystoker can be fitted with an oil burner. It would be less effiecient as the whole house heater, but should work fine for summertime domestic hot water..

I'd contact Keystoker and see if they recommend retro fitting your K-8 with an oil burner..

I Know EFM makes a DF [dual fuel] version of their 520 boiler.

Well you have a keystoker get the oil option put on it but oil will cost you more money to heat and you will have less of it burning with oil

There are a lot of good used oil boilers around with all the gas conversions going on, I saw one on craigslist for $150 last week that was 7 years old.
If you are going to burn oil, I would want to do it as efficiently as possible and for the least amount of money. A oil/solid fuel combo does not fit the bill in that department. Plus you have 100% backup if something fails. :idea:

How big is the 'heat sink' you are stuffing 16 tons of coal into. It has to be over 5000 sq ft, OR it has no roof, only walls.
WOW! I have 10,000 sq ft buildings that an AA 260 does on 12 tons.....hot water too. (10 apts,) An AHS 260 is doing 9400 sq ft easily and AA and AHS 130 are doing over 4000 sq ft on 8 tons annually. EFM 520's and a 900 easily do similar sizes with the same coal usage. I'd look over your total set-up, check the draft, reset the damper if necessary....or you are heating more than any of us is 'guesstimating'. 16 tons would equate to about 3000 gallons of oil.....that is no small usage number!

My vote is also to purchase a separate oil boiler and not go to the trouble of adding the option to your coal burner. Plenty of very good used equipment that a newbie changes out because some 'slickster' sold him a 94.5% efficient condensing gas boiler. Don't reinvent the wheel, there are many who passed before us who knew MUCH more than we ever will. :idea:

The heat sink I am heating is a big old farm house that I have been remodeling for 30 yrs and yes It is insulated. 2 upstairs apts. I am guessing that part of my problem is my draft. I dont Know much about how to set the draft and there are very few good plumbing and heaating people in this area. Therefore they are extremely busy and not really interested in supplying knowledge.
Back to the coal and oil combo. I have never shut my k-8 down over the summer because it heats the water. If I had a side by furnace to heat the water I am afraid that I would get leaks that would not seal back up in the winter. Also at the present time I have a small leak in the water fins so I am thinking the 25 yr old k-8 might be on its last leg.

Thanks for any info

I now understand your dilemma. You are wise to make an assessment as to the life expectancy of the K8. Perhaps your water is chemically aggressive; if so, that answers one big question. I like your logic, and I sure understand that it is more cost effective to use 10 tons of coal extra while rebuilding or utilizing what you have. If the K8 is off to a "better place", ( I'd have a welder look at the possibility or a repair first) I'd be looking at a rebuilt AA, AHS, EFM or a new Keystoker now. They are available and a new look at an old problem may be in your future. We all know money is tight, but this could save your behind if resolved while YOU are in charge and not a failed boiler is forcing your hand. I still support the separate boiler plan, I don't like dual fuel units. A stand-alone oil boiler would free you from any other combo deal. PM me if you need a lead or two on used, refurbed or rebuilt boilers. Good luck in the resolution of this issue. :D :o
