Wood pellet stove size question

Hi every body I am new to the forum and am wanting to get some advise on what BTU size of pellet stove I should buy. I live in an old 2 story farm house built in 1916 roughly 2500 sqf first and second floor it also has a full basement which we use every day. I currently have hot water heat with cast iron radiators in every room and would like to buy a pellet stove for in the basement and plumb into my existing hot water heat system using the crosslink conversion system I would like to use the pellet stove as my primary heat source and my boiler as a back up if possible. The house is insulated and has decent windows in it. It holds heat pretty well unless the wind is blowing 30 MPH. what size of pellet stove would I need to heat this house?

Thanks for any help, Wally

Hi Wally
I have a newer house with 3 bedrooms and an in-law apartment with 2 bedrooms. I am heating my house toasty warm and heating the In-laws domestic hot water with a harman P68. i would not think you would want to try any stove smaller than that. My basement is 75 to 80 deg most of the time. My wife keeps the upstairs at about 73 to 75 deg. I spend a lot of time standing out on the porch cooling off <Grin> when i have to work in the basement it is in shorts and tee shirt.
Are you doing forced hot water through the radiators? or Steam?

Hi thanks for the reply I am running forced hot water. My out put temp of my boiler ranges from 120 F to 140 F depending on how cold it is outside my boiler will run for about 30 min. every 2 hours or so to keep my temp inside at 65 F. Thanks

Hi Wally. Tecitout is prity slick. He knows. Go with the Harmon P68. You have to put it in Your basement. I put Mine in My garage. It works good with My hot water base board,but My basement is cold. I don't know how it would work with hot water radiators. What type of boiler do you have? How do You make hot water? it,s some thing Your going to try. Good luck.

Thanks for the reply my current boiler is a high efficiency 155000 btu lochinvar and I am just running a standard LP gas water heater but am going to upgrade to an indirect tank off of my boiler in the near future.

Hi Wally. I WAS using a indirect water heater. It was robbing alot of My Cross Links energy. Go with a electric hot water heater and install a side arm heat exchanger to it. It realy works good. I installed My last week with no electric, no pumps. I now have ample hot water and My systems water temp is up to sypply heat to My house. My pellet use went down. I know the side arm heat exchanger looks hooky, but It realy works good. My water tank is 50 gal, 46 inchs high. The heat exchanger is 40 inchs long. This summer I'll hook the electric to it.

Where the kits work well in baseboard and radiators, using the kits is that you alow a lower water temp say 130 degree temp circulate continuously thru the zones you wish to satisfying the room ( or zones home levels ) temp .Not trying to build a higher water temp with the zones opening a closing mixing the cooler water from the zones.Witch then allows you to control the feed rate of the stove to help you out more like the turtle than the Rabbit.( If you know what I mean ) Some people then put a hour meter on the stove to shut the stove down at night and then relighting it back up in the early morning or what ever works for there homes.It seem that adding the delta-t ( heat loose from water temp from return to supply ) back into the water continuously that most stoves can match the delta-t heat lose or the oil/elec/gas system may only need to bump the delta-t from time to time

Thanks for the reply's I am seriously thinking about purchasing one of these kits. I agree the Harman P68 would be the ideal stove but I have a hard time shelling out 3600.00 plus for a stove then cutting a hole in the side of it. I was considering the Magnum countyside or the heatilator PS50 these stoves are a little smaller in BTU ratings and not quite as nice as the Harman but do you guys think either of these stoves would be able to get the job done? I currently have a quadrafire MT. Vernon non AE and really like it I have heard the heatilator is made by the same company (hearth and home) so it would probably be my choice over the Magnum. What do you guys think?
Thanks again for the help, Wally

I really like the Cab-50 over the PS-50 because it holds 3 bags of pellets. (It's also cheaper than the PS-50). The firebox is identical to the PS-50 and uses the same kit. I did however use a different kit than what was normally used for that stove, it's larger and provides a little more heat. I intalled a flex line between the converter and the rest of the kit because I wanted the rest of the kit to be in another room behind the stove. The flex line also allows me to remove the coil from the stove without disconnecting the water line for a seasonal cleaning of the stove. The kit is too large for me to remove the back panels from the stove while it's in place. For me, even the smaller version would be an issue because I would install it toward the back of the firebox rather than center it. The firepot is toward the back and I want the kit to be directly over it where it's much hotter. I believe I have about 3/4 inch between the kit and the back of the box, that doesn't leave enough room to remove the back panels.

I have about the same sq' as you but my home is a gambrel with a 2 car garage on the first level. The stove is in the garage which works out well as the blower was adaquate to keep the area warm even though I have alot of leakage around the 2 doors. The rest of the home is heated with baseboard. I used 4 1/2 ton of pellets this year, I have 6 bags left at this time and may need to get a few more but it's been unusually cold and windy this winter. The stove doesn't run much, if at all, during the day now so I shouldn't need much more to get me through.
