Want to change from oil forced hot air to stoker...

PostBy: auntievintage On: Fri Nov 08, 2013 1:47 pm

Old farmhouse 2,500sf
Poorly insulated (working on it)
Oil forced (which is seldom used due to our hand-fired stove)
Basement is drafty granite stone, dirt floor...

...please advise with suggested model, reason & price-range

Any help is greatly appreciated as I don't personally know anyone with a stoker furnace! :?

It's not a precise measurement of what sized furnace you need but it's a place to start,....how many BTU's does your oil furnace fire at and does it adequately heat the house by itself?

It does not even come close to adequately heating. I am not sure of the BTU's. We rented it for a year and are planning to close on the house any day so we have to, first, get down there and remove the hundreds upon hundreds of existing jars of botulism and then replace the ducts with something smaller & insulated. One of the ducts, which we couldn't access, were disconnected, allowing the heat to go directly into the basement. The basement dipped below freezing for about 6 weeks straight so the large, non-insulated ducts were losing a lot of heat before it would enter the living space. As I mentioned, we relied mainly on our hand-fired stove upstairs. Now that we will own it, I am looking into a coal-stoker furnace, but I am not sure where to start.

You're going to need a heat loss calculation made. Can be confusing if you've never done one. Best to find an experienced heating company to do that. From there, you'll know how many BTU's you'll need to heat the house and stoker recommendations can be more intelligently offered. A new system with ductwork may be fairly pricey. :x

I just read about your weather in Etna and it's too cold for me!!

You really do need a heat loss calculation done, otherwise you risk buying the wrong size furnace. The price range for a decent new stoker is $ 4,000 to $ 8,000 dollars but not including installation of any kind. I'm surprised you were able to buy the home with a mortgage without a proper functioning central heating system.

Congrats on your purchase. Time is running out before the deep freeze arrives, so lets get the discussion going.

How much headroom do you have in the basement? 6-7' ceiling?

Do you or does someone you know how to properly size ductwork and lay it out?

What is your budget for the stoker & installation?

To help get an idea of where you need to be as far as BTU's go, take a look around the oil furnace - there should be a plate (I know boilers have them -not sure on furnaces) stating the BTU output and/or gallons per hour of oil from which BTU's can be roughly calculated.

Here's my oil boiler's info plate:

forgot to also mention:
you commented on your house 's. poor insulation..but "youre workin on it"
...consider your upgraded insulation...weatherization...new windows etc. (if indeed that is your plan ..??). before OVER sizing a furnace.
although its been essentially rebuilt...im heating 4000 sq ft. (house. built 1890)
...my stoker s. rated at 160 000 btu output.
I would think 125-150 k. btu should be fine...granted appropriate install.
...just my 2 cents

Oooh yeah - EXTREMELY good point there. Don't want a grossly oversized heating device after insulating - you won't be happy ... especially after spending north of 4 LARGE .... :shock:

They're trying to heat a drafty house pretty far up in Maine. I'd rather have some extra firepower than spend all of that time, effort and $ and wind up with equipment that isn't able to handle the true load under real-world operating conditions for coal appliances.

Guess it depends on the wallet - an all-out remodel will change things quite a bit ....

my thought regarding "oversizing" really depends pn if infact the envelope of the house is to be improved...
(i can only speak for my keystoker)...but im sure i could keep a much smaller house (than mine) quite comfortable (we dont like it over 70)...as the A150 is very capable at 'idling' at incredibly low temps.
...i wil say tho...that in shoulder seasons...idle..or low demand does seem to leave alot of unburnt coal in the ashpan....(typical stoker feed ?)
like i said...size and efficiency are two DIFFERENT things

what heats your DHW? are you planning on continuing to use your hand fired upstairs?... an easy, cost effective solution might be a Hyfire2 with a hot air jacket in the basement... these things can crank serious heat or be toned way back to a crawl.
