Well this is my first offical post.Ive been reading the loads of great info u guys have on here for months and now finally I have a question I couldnt find the answer to.Either number 1 its a dumb question since noones ever done it or number 2 its not possible, but either way here it goes. I bought a englander 25pdvc last week and was really impressed with it, but just like i always do i wonder if it can be better. So i ran across the englander site and noticed they have two different size convection blowers.One is for the 25pdvc which is 140 cfm and the second one is for the 25 pdv which is 250 cfm. Now i realize the 25pdv is a bigger stove but they both have the same control board so im assuming that its within limits on the amps. Space in the stove maybe the factor though im not sure.What is your thoughts on this and im i asking a dumb question.lol
 
Anything is possible, But will it physically fit into the stove. I'd see if you can get some dimensions before even buying one.

Having the larger cfm blower would move more CFM of air. But you will lower the air temp on the heat exchangers. If you notice the larger furnace's made buy Harman, ST Croix and US Stove to name a few. They use large CFM blowers. Mostly because these stoves are ducting heat into floor.wall vents. The temps have to be lower to prevent hot vents and burnt toes. So they move more air across the heat exchanger to lower the output temp. So your idea of a larger blower could work for you. You would move more air around so there should be a faster warm up period.

One draw back could be more blower noise? So if quiet is what your looking for, I'd say probably not!

If the bigger blower doesn't fit and your still interested in putting some thing larger in it. I have some links to different blowers with dimension's. Most prices are well under what the manufacture is asking for them too!

By the way welcome to the forum's, We like all questions and never consider them dumb. More like learning curves! :)
 
thanks for the fast reply. yea links would be great, im not worried about noise. Just want to get some heat moving around the basement

One other word of caution is the motor has to be close in amp draw and of the same type. I am not sure if the Englander uses a PSC or shaded pole. But in order for the control to vary the blower speed you need to stick to the same type. So if the motor has no attached capacitor you need a shaded pole. If there is a capacitor you need to use a PSC(split phase cap)

If the motor is only say 1.4 amp draw do not go far above that as it may tax the control panel and burn it out.

Are you heating an uninsulated basement?
 
As of right now yes its uninsulated.But i have a chimney there so i relined it and tryin to get some more heat moving around.The basement floods when we get 4+ inches of rain in 24 hours.So thats the first fix before tryin to insulate and thats been quoted at 7-8k to fix.Definitely not doing the convection blower until i get it insulated and the warranties expire

It's nearly impossible to heat an uninsulated basement with a pellet stove (or a wood stove as I found out years ago)... the cold block walls will simply absorb as much heat as you can throw at them...
 
yea ive read about that several times on here no choice for me though.It does heat some but it just takes a long time to heat the concrete up.Once it does it makes a difference. I really wanted it as a back up in case the power goes out and i have a generator in case it does

I had a Heatilator wood stove in my basement in the 70's... didn't heat anything at all. I thought I'd move my big wood stove down there to heat the space... not much better.
 
What can I do to get more "hot air blow" from the Englander 140 cfm convection blower? It seems to be less than before. Also is it typical for one side to be hotter than the other. Meaning on top of the stove in front. Turning up the feed and blower don't really seem to help heat up the room much.
 
Kyas,

I've noticed that too... if I put my hand up to the right-hand end of the front vent where the hot air comes out, it seems to be cooler than the air from the left-hand end. I inherited this stove from the previous home owner... it's a 2008.
 
ya know a box fan would help greatly moving the hot air around, it would be a heck of alot easier 2. BTW I have a summers heat/ englander that has a 240cfm blower on it and it is quite powerfull and not loud IMO.

You'll never get it to heat your uninsulated basement, why don't you put it upstairs? I went years simply heating the top floor of my house, ya the basement stays cold @ around 45-50 but unless your hanging out down there or you have problems with freezing pipes so what?
 
I have a 2010 Englander 25-PVDC that came from the factory with a D code setting. With help from this forum, I changed to a C code setting and the heat output jumped considerably. Of course so did my pellet usage as well. I have a 1600 ft2 metal building with 12 ft eaves and minimal insulation.

Wide open on the D code programming did not get it done. The C code programming on level 5 of 9 made all the difference and I am happy!

The newer model in my signature was set at the D programming probably to raise the efficiency rating.

The older 2006 model used the C code programming and I bought on Craigslist to flip It helped me get my 2010 model up to par..

I know you are in a basement but it might be worth checking out which setting you have in your control board.
 
I wouldn`t do it. The original fan is properly sized for the stove. The 25 PDVC doesn`t throw a whole lot of heat anyway and putting a larger fan on it isn`t apt to do much of anything. It will be a trade off at best. More air blowing out but cooler, plus more wattage used.
if Englanders thought more volume would be better they would have done it.

Ok for one it does throw out alot of heat for its size/cost. And the fact of saying that it would use extra wattage doesnt make much sense when people are putting large floor fans to move the heat. I disagree with it being a trade off especially since some are changing heat modes to put out more heat then the stove is intended to do.Wouldn't it make sense to move more of the heat away from the stove since it is creating more???

Ok, have it your way. Good luck to you..
 
I would like to know which one you ended up using??

And how long you've been using it?
 
I pulled mine out and cleaned the fan, boy was it filled with dust! My issue is that the blower does not seem very strong. I have a friend that has this same stove and hers blows a lot of air and you can here/feel it. Mine is very low, not much air blowing out. Any thoughts would be great! I did conduct the diagnostic test and everything matched what is was supposed to be. I also checked my lower 3 buttons and I have them set to 5-4-1.

It will put out cooler air, but the total heat extracted from the stove will increase somewhat. The heat that is transferred is dependent on both temperature and volume of air. Bottom line is that the heat exchanger works better when you keep the cold side colder.

Unfinished basements are tough to heat. My PDVC is in my basement workshop. This morning it took three hours to move the temperature from 54 to 68. Once it is there it has no trouble holding the temperature. That's in a 1200 sq ft basement with bare concrete walls and floor.But it sure does gulp down those pellets.
 
I apologize. My stove is not in the basement. It is in my living space. I pulled my convection blower out (room air blower). My issue is that the blower does not seem very strong. I have a friend that has this same stove and hers blows a lot of air and you can here/feel it. Mine is very low, not much air blowing out. Any thoughts would be great!

What do you have your blower set to on the upper blower setting button
 
My two upper settings are on 2 and 2 when it is running.
I don't understand. You want more convection blower air, you aren't using the capability of the blower. Set the Blower (second upper digit) to the highest number your ears will tolerate.
