Energy King 480EK vs Harman SF-2500-A

PostBy: DavidL On: Sat Jun 28, 2008 10:02 pm

I am new to the forum. I am looking into adding a coal/wood hot air furnace. I was going to get the Harman SF-2500-A, but they are back ordered until January. The dealer that I went to recommend the Energy King 480EK as a alternative to Harman. Does anyone have any experience with Energy King?

Also I am a little confused. The SF-2500-A says that it will heat 3200 sqft with a BTU rating of 120K (blower 1000 sfm). The 480EK says that it heats an area of 2000 sqft with a BTU rating of 160K (blower 1850 sfm)

I would think the 480EK would heat more that 2000 sqft

My house is 2800 sqft

Welcome to Anthracite David. Gets confusing doesn't it? I can't help you with the furnace models. Things are a little slow here in the summer apparently. I did a lot of research last winter before buying my coal stove. The problems with the heat and area ratings are many. The same Stove or furnace will put out varying amounts of heat depending on coal quality draft settings, and operator skill. Of course a home's heating requirements vary by a lot more factors than square footage. There are cubic footage, insulation value, air infiltration, climate, stove or furnace location for heat distribution, etc.

I think stove manufacturers vary from being overly optomistic about how much space their stoves will heat, to being cautious not to disapoint the customer by selling him a stove that is too small.

In northern NY, ( down to -20*F most winters )I need about 50K BTU to heat 1,200 sq. ft. of floor space in an older house with insulation, but not up to modern standards.

The depth and bredth of knowledge here is tremendous. Be patient and someone will probably be able to give you very good advice about the furnaces in question. Good luck. :)

Dave, what climate are you in. And give a few details about how well insulated, and if you have good air circulation, like into exisiting forced air vents. What size is your current furnace?
