lennox high vs. mid eff. ?

[bileshake]

I found two furnaces I'm torn between for my shop.

30x40x11.5 with 14x14 room in the middle. of the shop. I plan to insulate the walls R22 and the ceiling R40. The plan is to set up a forced air set up that will heat the 14/14 room to 60 all the time (music equipment) and and then open the rest of the shop when needed.

I found two furnaces, for 200 each, one is high eff. but older and the other is mid eff. and only six years old. I really like the simplistic venting on this type of furnace. would high efficency work in this kind of setup? The 14/14 room would have a therm and ducted normally and the rest of the shop would have a big run across the ceiling with ducts cut into it.

What are the model numbers on each?

Lenox is junk - I don't care what efficiency your looking at

You said that right , I won't even service one . The people around my neck of the woods have to call a company almost 80 miles away because no one around our area wants anything to do with them.

I used to be a Lennox dealer until I installed a few of the Old Pulse units.
Let my dealership go , wasn't worth the problems.

By the way , there are generally only 2 reasons people will have a used furnace available , one is they upgraded or they needed to replace .
Either way , used equipment is always someone else's problem being sold to you .
I junk every furnace I pull out and replace , no matter how well they say it runs or ran. I don't want to be part of a problem waiting to happen.
I just pulled one this wk end , the home owner had someone service it and it quit again , before I even worked on it , I took a good look at the heat exchanger , sure enough there was a crack in it , had I not looked I would have serviced a problem waiting to happen.
By the way this furnace was only a few years old according to the owner. It was 15 yrs old , as per the serial #

Lennox has had some units with problems over the years but I don't know of any company that hasn't, we find failed heat exchangers on a ton of carrier/bryant/payne units, it's bad enough that they are in a major class action type lawsuit.

Buying any furnace used is a gamble, some are just a bigger gamble then others.

One is a G26 - 75000 btu

I'm just trying to heat my two zone shop modestly without purchasing a new heat source for each room. The jam room is 196 square feet and want to keep it a steady temp while the rest of the shop (1000 square feet) will just be heat as you use it. If I use a hanging shop heater I'll have to get two.

I don't think your idea will work too well. The heating requirements of both spaces are too different. Why not keep it simple? Install a NG forced air unit heater for the garage part, and an electric heater for your jam room.

To steadily keep your room at 60F would only need about 2kW. You can install a permanently wire baseboard heater or in-wall fan forced heater, or if you need the wall space a ceiling heater.

My option would be an electric radiant cove heater: completely silent so won't interfere with your music-making, no dust blown around, and mounts high so you've got all the wall space available:

I've got a UFO radiant heater maybe I'll try that when the room is closed in and see how much more I need. I just didn't want to have the hydro bill running up when I'm not out there.
