Englander 25pvdc tstat question

[jeremygrimm]

Hello again. It's that time of year. I recently installed a Thermastat on my older englander 25pvdc. The temp here in ohio dropped to 44 last night, so I thought it was good time as any to fire the pellet stove up.

Well... ha.. I put blower and feed both on 9 like I read. At the time I lit it the basement was 65 degrees. Within an hour the basement was 69 degrees and the stove slowed down on heat. The problem was it didn't slow down enough. This stove heats roughly 2900 sqft the basement is 1480 sqft with the upstairs being the same size. I leave my basement door open and the ceiling is unfinished in the basement so I get heat upstairs that way also. It's still cement floor in the basement but all walls are insulated well and drywalled. By the time I went to bed it was 72 downstairs and 73 upstairs and I used about a half a bag of pellets (roughly ) in about 6 hours. I turned it down to 1 on the feed not knowing if it would make a difference. I woke up this morning at 6:30 with an empty, cool pellet stove (not cold yet but shut off and empty) and the house was 74 degrees. I feel I went through pellets a little fast and maybe a tstat is useless. I'm running on c mode. What's some advice to conserve pellets?

I have a cheap Tstat on mine. What option do you have? Off/on/fan??
Did you take the jumper out of the control panel on the stove?

 

[jeremygrimm]

Yes. I took the jumper out. I'm positive I have it hooked up correctly. I did the test on it where it has the dashes on the display. The tstat seems to work, I think it may just be to warm outside yet for the stove. It hit 50 degrees out today and I have yet to turn the heat on and the house is still 70 degrees.

Do you have the 25-PDV or the 25-PDVC? From your profile pick it looks like a 25-PDV. If you think are using too many pellets in idle mode, then you may need to adjust the Low Fuel Feed to tune the proper feed rate at idle.

Edited to remove incorrect information.

Do you have the 25-PDV or the 25-PDVC? From your profile pick it looks like a 25-PDV. The 25-PDVC can be set to completely turn off the stove if no heat is needed, it will then perform a self start once heat is called. The 25-PDV can only go to into idle mode (the 25-PDVC can also be set to do this versus shutting down). It sounds like your stove went into idle mode. If you think are using too many pellets in idle mode, then you may need to adjust the Low Fuel Feed to tune the proper feed rate at idle.

I think you have this wrong or maybe the newer models have it but my pdvc only has hi/low when using Tstat. There is no auto.

Yup, I misread the chart in (broken link removed to http://www.heatredefined.com/assets/images/general/DTSTAT_Thermostat_Instructions.pdf) Englander thermostat instruction manual. Sorry about that.

If there is a PDV or PDVC that auto shuts down and restarts on a stat it is news to me. Only ones I have seen will just do hi/lo on a stat.

[Dr.Faustus]

With the thermostat, whatever you set the stove on will be the maximum it can achieve when the stat is calling for heat. For instance, if you set it on 9-9 and it calls for heat, the stove will run on 9-9 until the stat stops calling for heat. Then it will run on 1-1 until the next heat call. If you set the stove on 4-4 and the stat calls for heat, the stove will run at 4-4 until the stat is satisfied then run at 1-1 again until the next call. It's still a bit warm out to have the stove running 9-9 even on a stat.
I think by the time the stat stopped calling for heat it way overshot the goal temp.

Hope this helps

I guess from what it looked like to me 1-1 was using way to many pellets. Is there an adjustment to lower the 1-1? I am on c mode. Perhaps I need to switch to a different mode?

 

[jeremygrimm]

Ok. I may have a reason it seems to go through a lot of pellets. My low fuel feed (bottom left button) is set on 5. Should I be turning that down to 1?

 

[jeremygrimm]

And yes. It is a 25pvd

 

[Dr.Faustus]

you can lower the low fuel feed and adjust the air but then you have to test the settings. you don't want to lower the fuel feed so low that you have the fire extinguish, then dump in a few pellets, relight and repeat. that is an extremely dirty burn. adjust so that the stove has a continuous but small flame on setting 1-1. You can even try adjusting the restrictor plate at the bottom of the hopper as well. the more you close the plate, the lower the feed rate on any setting.

Thank you so much.
