Setback Feature and Coal Usage

Setback Feature and Coal Usage

PostBy: traderfjp On: Fri Oct 24, 2008 4:21 pm

I wanted to get opinions from Coaltrol users who have used the setback feature. I find it works great but I'm wondering if I would use less coal if I keep the house at one temp instead of letting the house cool off and then having to ramp up my stoker to get back to a higher temp? Right now I set my thermostat for 70 during the day and to ramp up to 74 about 2 hours before I get home. I was thinking of just keeping it at 73.

Thanks

I never really kept track of my usage, but I normally keep it at one temp (or within a degree or two). I have all the setting within 1 or 2 degrees on the setback. I don't think there would be much difference.

I know my usage should be less with the heat jacket on the stove now. I have noticed it is mostly idles and kicking out some serious heat upstairs....

In my case I set back 2 degrees. I have found that a 5 degree set back takes too long to get back to temp at my house (several hours). You would be surprised how much less the stoker runs even at a 2 degree difference. The thing about my house (open design) is what ever temp the t-stat is reading the rest of my house is already at this temp. If I put my setback at 5 degrees I have to heat the entire 2000sqft with a 14ft high vaulted ceiling in the living room back up 5 degrees and it takes quite a while. I would think that anything more than a 5* setback would cause you to use the same amount or more coal to bring it back to temp.

It seems my stove idles along hardly using any coal but if I set the thermostat to a 4 degree setback the stove really fires hard to get the house to that temp. I'm going to experiment with a 2 degree set back and see what happens. I was doing 4 and I think that is too much.

I tried it last year. On days/nights that were 30 or above I think it may have some benefit, but when it gets colder I felt like it was really firing hard to catch up. I just leave it set at one temp now. What i did do is to set the convection fan to run a little all the time now (V3 firmware) so it's always washing heat off the stove. Seems to work fine.

How did you set the convection fan to run as you suggested? Are u talking about manual or did you play with the CFM?

I set it to manual while it's still warm enough to keep the stove at idle. I'm going to mess with the other settings when it gets colder to see if I can have it run all the time while still allowing it to ramp up when needed. Not sure this is possible with the current programming or not.

There is a setting in the advanced menu that will turn on the CFM at a lower firing rate than the default setting. The fan can also be set to run at a minimum speed. I haven't really played with it too much. Right now it's 42 out and the stove is at idle. The stove temp is around 100-120 and the CFM is off. I figured that I would let the Coaltrol determine when to turn on the the CFM and save some money on electricity.
