(broken link removed) sold at lowes home improvement are about the least expensive new stoves you can buy.
You also have to make sure you dont get too big a pellet stove for the area you want 2 heat , because you could have a problem that on the lowest setting it still makes too much heat for you to be comfortable.
Too small a stove wont heat the farther reaches of the area, even on the highest settings.
If you have many rooms, larger is better, because you can control the temp to an extent by opening the doors to the cold rooms , to cool down the room a larger stove might overheat.
Most people buy a pellet stove , see if it heats the room it is in , then open the door to the next room & see if it will heat that room too, & if it does, they open the door to a 3rd room to see if they can heat that also & so on , until they find a room that the stove dont heat & then they moan & groan that they should have bought a bigger stove .
Human nature,go figure.
HAVE TO CHECK WITH LANDLORD FIRST,FIRE INSURANCE COMPANY WILL HAVE TO BE NOTIFIED, insurance rates may be increased & a professional installation, up to fire codes
and certified will be demanded because it is a multi family dwelling.
Rental law states that objects attached to the building become the property of the landlord,
so you would need to get a written agreement with him so that he can't claim the pellet stove belongs to him after the gf moves out.
The vent kit, which is actually the part attached to the building will stay with the landlord,
unelse you make arraingements to return the wall to original condition before vacating.
That means that you cant tell a vent kit was ever installed there & the paint matches.
No One sells a "pellet stove for appartments" , it is the same stove weather you rent a place or hold the deed.
