Oil/Keystoker Install Questions

Oil/Keystoker Install Questions

PostBy: jrn8265 On: Mon Jul 28, 2008 1:31 pm

I measured my home and come up with 1600SF of living space to be heated (minus the basement) All ceilings are standard 8 feet high and I did not include the "height" of each room in the 1600sf measurment. The house is two floors and the basement. Basement not to be heated.

I currently have an oil furnace with the standard forced hot air and three returns from the first floor tied into the furnace/hotair/ac. (ac is ouside unit)

I plan on installing a keystoker 105 unit in the basement with coal trol placed in the first floor family room. (not in basement where the keystoker unit will be)Keystoker has a 8" vent on the top and then a 6" chimney vent on the top also. My chimney is 26 feet long, stainless steel, just cleaned and checked.

I will be putting a TEE between the oil furnance and the keystoker 105, sharing the same chimney.

Questions:

What is the best iway to tie this all in to most effectively heat my home?

Do you think the 105 will be enough heat?

Can I get by with just the floor fan return built into the keystoker with only basement air being used?

Appreciate your thoughts!

Greg L, do you have any suggestions? You seem to be one of the experts on this site. As detailed as you can be would be greatly appreciated. Thank you!

The 105K should be more then enough to heat your home if it's fairly well insulated. Just make sure you set up both a feed and a return air duct to help get the most out your system, you may also want to look at using an outside air source to make up for all the air that will be going out your chimney.

I'm not sure how you'd tie a stove like this into ductwork. If you're looking to do this, I'd look at a coal forced air furnace:

Thanks guys, the keystoker 105 will be connected to the duckwork. Is it enough to just tie the return from the existing duckwork into the bottom of the stove and maybe keep a window cracked in the basement also?

I guess it would be dependant on where the window is located from the stove. But with the outside air connected to the fan you are not going to be having cold air just pouring into your basement and basically cooling off what your stove is trying to heat up. Seems you would not be using your stove in the most efficient way possible. This wouldn't matter if you basement is finished or unfinished as the stove would be heating the space it is in not matter what. But if your basement isn't finished you should at least invest some time and money to get it well insulated so you wouldn't be loosing any heat to the ground outside. If the basement is finished than you could remove some of the floor insulation as it would greatly help to heat up the upstairs of the house.

I guess being new to this my question is am I better off connecting a direct feed of outside air to the stove or instead connect to the return from the duckwork to the stove to help foster circulation through the home?

So fresh air directly or return air from duckwork?

Personally I'm not sure of this myself yet. You might want to post that question in the outside air thread and maybe read through it to see if you can get a better understanding of what you should do.

jrn,

First off, you do NOT want to use a "tee" to connect the 2 heating appliance chimneys. That is a no-no. One option is to use your existing chimney for the coal heater and use a power vent for the oil burner. The power vent would only operate when the oil burner runs. 2nd option is to add another chimney.

The hot air from the coal heater gets hooked into the cold air return of the oil burner. Then you can use the oil burner's fan to circulate the air. A good diagram on the ductwork install can be found here : http://www.leisurelinestoves.com/1904137.html

The outside cold air make up is connected to the combustion fan inlet of the coal stove.

As far as the sizing of the stove, what is the btu rating of your current oil furnace ??? Use that as a guide to determine what size coal stove to purchase.

Rick, so I can still connect the heat vent off the stove to the cold air return of the furnace even though my stove already has a 350 cfm blower in it....meaning I can have that 350 cfm fan on in the stove as well as the furnace fan if I want that on also? thanks

In a nutshell, yes.

That 350 cfm is only to pull the heat off the stove and into the ductwork or out in an open room. It would not push the heat very far in your ductwork. If you have a thermostat controlling that convection fan on the Keystoker, you can wire the oil burner's fan to kick on at the same time. You may have to use a relay as I'm not sure if the CoalTrol could handle the load of the oil burner fan.

Ahhh....I get it.....


so I now have a honeywell programmable thermostat for the furnance. I guess I can hook up the blower on the furnace to the coal trol also (or use relay) so that when I use the stoker with the coal trol thermostat both blowers go on...when the stokers not being used the other thermostat works as usual with just the oil furnace on and its blower on...no 350cfm blower on...right?

My feelings are you need the 350 to pull the heat off the stoker and to put it into the cold air return of the oil burner. The oil burner fan then takes that nice coal heated air and distributes it throughout the house using your existing ductwork.

However on the LL hot air jacket method, I think they do not want you to use the distribution fan. Their instructions say that this set up would allow the oil furnace fan to suck the heat off the coal heater more evenly.

I'll guess we all will find out which method works best this winter.


Rick

edit: BTW I really don't think you will want to use the oil without the coal burner heating the air. Unless of course you would be away on vacation or something like that. Once you get used to having the nice cheap coal heat, you will not want just oil. And these stoves are so easy to light that even if you got a warm spell and shut down the coal heater, you could have a new fire started and be making heat in as little as 15 minutes.
