So put a fan switch on to override it like every other stove they make... But give me the option


Sherwood isn't designing the boards. They use the ACE controllers. Its a turn key controller. Sherwood sticks to stove design. And prefers to have a one touch controller that is easy to use. I really doubt they would change it just for you and your desire to have a variable fan. Fan too low stove gets hot, Fan too high it blows cold air at ya. I think they prefer the push the on button, Set the heat level. Step back and feel the heat!

A safety circuit could be added to it a long with the variable fan(relay-rheostat). But why mess with what works?
 
It's a fine point in the difference. A regular thermostat with most stoves functions in two fashions. The first is on/off. When the temp is reached the stove goes into a shut down cycle and turns off then starts again once the thermostat calls for heat. This method uses less pellets but is harder on igniter. The second would be referred to as Hi/Lo mode. When the thermostat is satisfied the stove turns down to bare minimum level to maintain the fire. This method uses a bit more pellets but saves your igniter.
The Harman stove when using the room probe never really turns the stove on high or down low. It constantly makes small adjustments to the fire to keep the temperature as constant as possible while using a steady amount of pellets.

Most people when they have their stoves running off a thermostat have a swing temp of 2-4 degrees making your house spike a little bit even past that. When your thermostat calls for heat your stove still has to ramp up it's heat which takes anything from a few minutes from a low maintenance fire to 15 minutes from a dead cold start causing a larger (but still small) temperature difference than you get using the Harman room probe which maintains the same temperature constantly. Personally I prefer the wireless, or wired programmable remotes that you can set to have your stove start or stop at different temps at different times of the day but that difference in the constant steady temperature rather than a several degree constant swinging temperature is what Harman likes to use as one of their selling points.


Very Good Explanation. I like it too!
 
Coolaide? No thanks can't stand the stuff. I'll take some popcorn and a brewski please! :p

Don't forget to mention it may take a day or 2 for the Harman to stop the auger and actually shut itself down once you turn it to off. Why you may ask, Is they are afraid of a burnback! ;hm

Why is it spell check doesn't like Harman, It keeps putting Harmon in? I like Hormone better. ;)
 
My Omega goes straight to low, But the heat exchanger is massive and I see minimal heat rise. What it does do is stop feeding pellets for a couple of cycles to let the flame die down.
I'm almost certain/sure the M55 has the same program, Just different feed rates and blower voltages for the smaller unit.




If I could find a stat with a swing of .25(1/2 a degree total) and I am sure I ccould hold the temp right at 72::F all day long when its in high/low mode. I prefer a swing of at least 1::F for spring/fall shoulder days to ease the work load on the igniter.

I will have to check and see if mine stops feeding, I don't think it does though. Maybe this year I willsee if it trips the high limit if I don't run the room blower on high.

Obviously the spell check thinks every stove should have been named after me..... Silly Harman people getting my name wrong anyways.

If you have a Harman it shouldn't trip by running the convection blower on low. It will try to maintain a set exhaust temp. Esp.
 
There's always the old Austroflamme controller. On/off and heat level. Perfect! I'm going to have a showdown in the store soon 52i vs the M55...gotta get my hands on some real crappy bags of infernos, preferably ones with rips and tears duct taped together that got wet from being outside. May the better stove win!

Using a pellet stove to try to heat a almost 3000 sq ft home is crazy, you'll be lucky to just warm the room it's in, also it will make the rest of the rooms feel cold, I'm sure you can afford that home, you can afford to heat it also!
Ambiance is all your looking for.
Are you ready to waste time buying, loading, cleaning it daily/weekly?
Almost my whole life that I've moved away from my moms i have had homes heated by wood or pellet, never a uniformly heated house, my kids 20/17 yrs old have NEVER felt a nice evenly warm home and i've lived in 1500sqft Cape's.

I feel the biased vibs of a Harman lover, I doubt the test will be squared up fair! So be it.

There's a reason Harman released the 52i, (I don't have the sales data). But I bet its to get some sales back of what the M55 cast insert has takith away!

I sense the yearn of a pellet furnace? ;)

Welcome to the Forum Ken. I haven't been by Glover in quite some time. Need to drop in soon and say hi.

Pellet King, I don't expect to be able to heat the entire home. However, based on the many posts I've read in this forum, I think I can expect that it will substantially cut down my oil bill over the winter months. Time will tell I guess. The ambiance in the room where we spend much of our time is an added benefit. A pellet burner in the future may be a possibility, but not until the technology is a bit more mature and government incentives for this alternative heat source (similar to solar and wind) are also available to full house pellet systems.
 
ozy

the only way to really know is to try it

i put a 25kish btu englander in the basement , never runs on high cause it's just too much heat, everyone told me a pellet stove is a space heater so put it in the room you want to heat , it wonk work in a basement , it has to have an aok , it will not keep the upstairs warm , (i'm in a rancher w/ 3/4 basement) , the basement will suck all the heat from the stove , yada yada yada

the stove is right under the kitchen , which used to be COLD , open the cabinet and grap a plate that was 50 deg cold , now the dog lays in there

the liv room , one br and both baths are way warmer feeling (they are all on top of the 3/4 basement) even if i run the stove at the level needed to keep the tstat at 70 , where i kept it w/ the oil boiler/baseboard , hitting 73-74 on the stat was not a problem , the back 2 br's (over a crawlspace) were still in the high 50's on the coldest of windy nights , an little ceramic cube heater would take that edge right off

ceiling fan in every room except baths , box fan in basement on low moving air around , heat radiates through floor into walls , furniture , dishes, me , ect

used 153 gals of oil since jan 1st this year when i started burning , 100 gals in the 3 weeks before that , was burning 5-700 gals per year , trying for 200 yr w/ the pellet stove , that 153 lasted till july when i filled the tank , boiler does dhw as well

stoves getting a bigger vent and aok this week along w/ uber cleaning/rebuild , maybe i will see an improvement

anyways , if you put a stove in your house , it will "feel" warmer

if you have a zoned system now , you're set for a good savings

I'm heating 2200-2400 sq ft with a 48k btu stove. With a stove in the 60k+ range (a Harman p68), you could be heating your entire 3000 sq ft. I live in Maine and have a buddy that heats somewhere in the range of 2800+ sq ft comfortably. His house is an old colonial with 10 foot ceilings, poorly insulated, old windows, etc. and he keeps his home warm with a p68 and he keeps his running on low.
 
I have a tiny house built 1924. Used to go through 975 ish gallons of propane a year, I bought 150 gallons two and half years ago and pellets do the whole heating enchilada. I disconnected the mains for the propane furnace. Suppose it would be different had I had a forced hotwater system

I have a boiler, so it still runs to heat the water - so I can't get off oil 100%.
 
Most insurance companies will not cover a house with a pellet stove as primary heat and no oil or gas system connected as a backup. Always good to check with the insurance company for their policy before there is a disaster

Really.
 
All this talk of thermostat problems makes me glad I went with the boiler. It may be in the basement and not pretty to look at but the same thermostats from the oil boiler still control the heated water flow and the pellet boiler modulates itself to keep the water between your setpoint temperatures. Plus the whole house is heated, no matter the square footage, with multiple zones and thermostats. Works exactly like an oil boiler except you have to feed it pellets and the oil man will forget where you live.

Our dog has found the cool spot in the house. The living door cozy. We now use another stove to make up for the extreme days. The PC45 does almost all the work rarely burning more than 60lbs a day. DSCN0213 - Copy.JPG
