All forum members should be the first to see pics of the new stove Mike and Corie! send em our way and you'll be sold out this coming year!

ok, here ya go , this is the freestanding version (bear in mind there migt be a couple small cosmetic changes before its released

Very nice guys! Do I see an ash pan on that free standing? I love the bay window look! Is the stove going to be special order or will it be out at the big box stores? Does it still use the 2 auger system? Thanks for posting, Mike!

can you tell me what model this is? and I love the bay window look! Is the stove going to be special order or will it be out at the big box stores? Does it still use the 2 auger system?

its due out late next month (tentitive) i have no idea what MSRP will be , and it is a single auger top feed system. will be "on-off" t-stat capable and will very likely be a special order item at least this year.this unit can be after purchase converted to an insert from freestanding and vice versa with an optional kit we will carry. by the way , the CPM i mentioned earlier in this thread will be a special order only unit this season as well.
 
Mike, would you be able to tell me if any stores in my area have already ordered the 10-CPM in?
thanks so much for your help :cheese:

cpm's i believe will not be in stores before 9/1/08 i'll double check but im thinking thats what i was told. most of the stores are ordering 25-pdv and pdvc units as they can get them in stoock faster, they are much less complecated to build so we are able to manufacture more of them faster, and the stores seem to be loking to order what they can get on the shelves fastest in larger numbers , the CPM in most stores will not be a stock item anyway but availible as special order product. if you check with the "pro desk" at depot , or the "special order section" at lowes you should be able to get some info. i will try to provide better info as soon as i can get it myself, the production side of the house isnt necessarily my rice bowl so it may take me a few days.

Many of the standard digital, setbeck, millivolt (as compared to line voltage), programmable thermostats have a slop feature which is an adjustable swing in temperature to prevent the short cycle of a powerful pellet stove. So you can set it to turn on at 65 and off at 75 for example.

I had a honeywell that tried to keep my old house at exactly 68 all the time. The NG furnace would cycle several times per hour.

This is known as the temperature differential.
In a central heating system it is normally adjusted at approx 2 degrees to keep the room temp constant and not having the furnace cycle more often than necessary.

IMO this fine tuning feature is nearly useless with a crude system such as a pellet stove but it`s there anyway and can be set.

In non digital thermostats there is a heat anticipator (tiny low voltage heating element) that breaks the connection just before the thermostat reaches it`s set temperature to allow for the additional heat given off from the heat system after shutdown as in a baseboard hot water system.
My digital setback thermostats have this adjustable feature too but I haven`t given it`s operation much thought . I`d have to think it was timed electronically to simulate a heat anticipator.
Maybe some forum electronics tech has more on this as I`m an electrician with limited technical electronics knowledge.

The reason that I would like an adjustable swing on a thermostat is so that you can force the stove to burn in long burns rather than a short cycle. It seems that the on/off operation mode for these stoves would benefit from less on/off cycles even at the cost of a larger room temp swing.
 
I don't think you are going to find a conventional wall thermostat that will allow 10 degrees of slop, but if you really want that, there are mechanical thermostats that allow you to set the "on" and "off" points independently. Most of the stats are trying to achieve 1/2 degree of swing, but obviously, this will be a lot of wear and tear on your ignitor. The better electronic thermostats out there will allow you to set the cycle rate from 1X an hour (steam systems) to 6X or more an hour for electric resistance systems. Gas and oil systems typically cycle about 3X per hour and heat pumps just run all the time...
