Do you want to stay with a pellet stove? They do require cleaning and maintenance on a regular basis. Some here will tell you a wood stove is the only way to go, but there are advantages to the thermostatically controllable p-stoves. If I were looking for a new stove, I'd check out the Avalon, Lopi and England stoves also. Inserts and freestanders from Travis (the Avalon and Lopi) have some great features and capacities, they have been around for years and are very well respected. They are a little pricy, but very reliable. Englander stoves are known here as the best bang for the buck. Not only that they are a direct support company. Because they sell through non-servicing sellers like Home Depot and Lowe's the company handles parts and servicing questions directly. Their customer service manager is an active member of the forum and they recently hired one of our own as an engineer, check the archives for Corie's Job search and trip to Reno.
I suppose the analogy would be asking what new car should I buy? There are lots of choices and this group will give your their biased and unbiased opinions. You can automatically eliminate the small stoves, but there are some very efficient medium stoves that might meet your needs. Give us some ideas like sedan, sports car, pick up, SUV. If you get my drift. There are many more stove makers than Quad and Harmon. You can also consider multi-fuels and corn burners.
At any rate welcome to the Hearth, get comfortable you have a lot of reading to do.
