Space heating savings.

There are many ways a consumer can save by heating with wood pellets these days. We save carbon emissions. We save on electricity in many cases, and of course many of us save money compared to using other fuel types such as oil and propane. One way to save that is often overlooked is the conservation that comes with using a single point heat source as opposed to a whole house heating system.
Wood pellet heat is an environmentally friendly heat source. It is EPA exempted because of its low emissions. It's near complete combustion leaves very little ash to clean up, and wood pellets are considered carbon neutral. One benefit a homeowner might notice is a reduction in their electrical bill. While pellet stoves do use electricity to regulate air and fuel feeds, and to distribute heat through the house they use on average 1/5 the energy of a forced hot air system. A pellet stove uses an average of 250-300 watts on a mid setting. Compare this to a furnace system that can consume upwards of 5000 watts. I do notice that the window air conditioner I use in my office makes my summer heating bills higher than my winter bills. It's specs rate it at 750 watts!
Another plus is the ability to have a fully functioning convective heat source with the use of a battery backup system. I have a backup that is attached to a battery and my stove at all times. When the power goes out the backup automatically engages switching over to battery power. When the power comes back on it trickle charges the battery. Some stoves, such as Harman's Accentra have the ability to turn off the distribution blower. This limits the convective flow but is a great energy saver in a power outage situation. Harman also has the ability to disable the igniter saving even more.
Many whole house systems are tasked with keeping every corner of your home warm. Some homes have only one or two thermostats on which to base that warmth. You end up heating every room all day and night whether you are using them or not. When many of my customers install a pellet stove in their home, they turn their whole house system down if not off. This results in a warm and inviting living space, and cooler outlying areas such as bedrooms. Not a big difference comfort-wise but enough to notice a savings on your monthly fuel and maybe even electric bill. An example could be my old ranch house that was kept around 70 degrees in the main living areas, and 65 in outlying rooms. The difference is often just enough that the introduction of the pellet stove brought the family back together in the living room. Not overheating outlying areas can reduce your fuel consumption by a noticeable amount. I certianly feel comfortable about keeping rarely used rooms five to ten degrees cooler than the rooms we use each and every day.
