Indoor Coal Boiler in Out Building 50' Away to Heat House

Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

The heatmor 200cs OWB I quit using was rated at 180,000 BTU by a factory rep. I am running my EFM 520 5 teeth feed and my Logstor is 1" I.D. , approx 108 foot from boiler to heat exchanger not including elbows. This supplies enough to heat for a 3400 sq ft brick home built in 1865.

The house is a two story with 13 ft. Ceilings. We use anthracite here as there is a big amish community and lots of anthracite coal. The costs of propane 4000 so I went to lopi liberty stove after 1 year its sitting in my garage waiting for me to sell it. I went through a great antique coal stove guy and got a herrold just for the add on room which is big and with volted ceiling. I knew I would do something for the rest of house. This outbuilding is nice and already has power ...220 and 110 and has old fashioned hand pump watwr supply. I don't wantto build another addition. The herrold heats the addition and half the lower level of the rest of the house. I want consistent heat and read about greg and others building an outbuilding and putting an indoor coal boiler stoker and then using water lines to heat a home and an outbuilding. The herrold is great and is a beautiful centerpiece of the addition. We will still use this as the ceilings are so tall and theblue flames are a site to see. Its not enough as it is a room or area heater. I wantto be able to use water to air exchanger.

What is the rating of the propane furnace? I would venture a guess that it is in the neighborhood of 200-300K btu. To get that kind of heat transferred from boiler into house, flow rates of 25-30 gallons per minute are necessary. That's assuming a 20 degree differential across the coil. There are a couple ways to get that kind of flow rates. Small diameter pipe/ large pump, large diameter pipe/ smaller pump. Sometimes a solution right in the middle is the answer. Medium diameter pipe/medium pump. The beat way to find out the best solution is to do a heat loss calculation to figure the heat load. I think a 1.5" pex-al-pex with a taco 013 pump might work better.
I think a man does what he can, untill his destiny is revealed. Right now that is trying to sell my EFM plate boilers in 520 and 700 sizes.

The people who owned the house befor meput in two propanefurnaces. One for the level and one for the upstairs. Same for the ac. Big one downstairs and smaller onefor upstairs. By leaving the doors to upstairs open I will be able to let physics do its job.

The old PM's will sit in your Inbox until you delete them. The messages you sent will sit in your Outbox pretty much until the other person receives them, at which time they will enter your Sent file. Unless you actively delete specific sent messages, your Sent file contains your most recent sent messages (up to 200).

Hope this helps (and that it is accurate :lol: ).

I have to make the existing out building work. I don't undestand why I will lose so heat if I use well insulated lines. Also I will be using the outbuilding. I don't want to do a owb and burn up money.
FYI don't go cheap route for underground insulate pipes, I've used this http://www.thermopex.com/ ... Also 2 friends have this with 300 ft run, one been in ground for 10 yrs with no issue. Keystoker makes five units the have BTU ratings 125,000 150,000 250,000 350,000 450,000 someone else will be able to speak up on other manufactures on btu. What ever you choose you'll be happy allot of great coal units to choose from.

Those are the bonnet output ratings of the Keystoker hot air furnaces. The boiler ratings are lower down on the Keystoker home page.

I would be very careful comparing boilers using claimed ratings, since the bases for those claims are not always consistent (input vs. output and net vs. gross values), and some claims are based on conditions that are not easy to sustain in practice.

Where do I find the heat loss calculation so I can figure the heat load.

Thanks,
