High Fuel Prices And A $1,500 Tax Credit Ignite Interest In Alternative Heating Sources. Image credit:Buffalo News, Money To Burn

Central heating is pretty much the US norm for standalone family residences. There are exceptions in far southern homes or in three season cottages and cabins, where space heaters suffice. Otherwise, the presence of a space heater - I include wood and pellet stoves in this category - is often viewed as a symptom of poor construction, leaky windows, poverty, or infirmity. Yet remarkably, store shelves are full of plug-in space heaters; and wood stoves are selling at a record clip. Why? Builders commonly cut costs by installing a single thermostat, making an entire home a central heating "zone." Consequently, Americans often heat empty rooms for an average household size of three persons (2.59, per the US Census of 2000) while sharing an average of 2,330 square feet. What can the "one zoner" can do to lower the heating bill and avoid family members fighting over the thermostat settings?

While wood-burning and pellet stoves can be quaint and efficient, they can also be dangerous.

To avoid injuries and damaged property, ask yourself these four questions, posed by QBE Regional Insurance Senior Vice President Charles Valinotti.

Was it installed by a professional? Installing a stove isn't a do-it-yourself job. Work with a professional. If the stove was installed before you moved in, it's worth having it inspected. One tip-off: If it has more than two connector pipes, it's probably been tampered with, Valinotti warns.

It takes six to nine months to season firewood, a process in which most of the moisture is extracted from the wood.

If you skip the seasoning and burn green logs, you add pollution to the air, creosote to the chimney and you don't get as much heat from the wood.

Here's what a state report says on the topic:Freshly cut wood contains up to 80% moisture, and must be "seasoned" (dried to 20-25% moisture content) before burning. Wood containing more than 25% moisture is "wet" or "green", and should never be burned in a fireplace or woodstove. read more......
