Hot Trends in Home Heating
by author Susan Safyan

With the cost of fossil fuels beginning to catch up to the price of ice wines, it’s time for those of us in the Great White North to look for more efficient home-heating systems.

In the last few years the cost of heating our homes has soared (since 2001, oil prices have jumped almost 300 percent). What’s worse, every time the furnace comes on, we’re adding carbon dioxide (CO₂)–greenhouse gases–to the environment. The average Canadian produces five tons of greenhouse gases each year. Can we reduce our heating costs and help meet Canada’s One-Tonne Challenge? Our friends Joe and Ninel found out they could do just that.

Saving Money

Joe and Ninel installed a high-efficiency wood-pellet stove in their home two years ago. Joe estimates they’ve cut their annual heating bill by about a third (in general, savings range between 25 and 50 percent when compared with oil, natural gas, or electric heat). The stove itself cost about $3,000; pellets run about $400 to $600 per year.

The stove burns small pellets made from dried, ground wood and other biomass waste. The stove’s “hopper” holds about 50 kg of pellets. Pellet stoves can be installed as freestanding stoves, fireplace inserts, or furnaces. Joe and Ninel’s is an attractive free-standing model, with a porcelain finish and a glass bay window. It easily heats the 1,000 sq ft (93 sq m) main floor of their home.

Pellet stoves need less installation space than other types of wood-burning stoves, and because they’re power vented, they can be installed anywhere in a home, as long as they’re placed on a noncombustible surface (such as a stone or tile hearth pad) and given at least three feet (1 m) of vertical chimney.

All pellet stoves require electricity to operate–you’re not going off the grid with this technology. Some stoves feature a fully automatic ignition controlled by a thermostat. “What if the power goes off?” I asked Ninel. She explained that their stove comes with a battery pack in case of a power outage. Ninel suggests buying an energy-efficient model that meets CSA and EPA standards.

The stoves do require more regular maintenance than a conventional heating system. Joe told me that they have to fill the hopper with pellets (every day in the winter); empty the ash pan once a week; regularly clean the hopper, trap, and glass; and get the stove and chimney professionally serviced annually.

Saving the Environment

Pellet fuel gives the cleanest burn (the lowest CO₂ emissions) of any solid-fuel burning system. Wood pellets emit about 5.3 kg of CO₂ per gigajoule (GJ) of energy. In comparison, natural gas emissions are about 50 kg of CO₂ per GJ. The pellets are made from a renewable, recycled resource. The almost complete combustion of the fuel in the stove ensures that, with proper maintenance, there’s almost no wood smoke emitted into the room, either.

“The stove is quiet, clean, and efficient,” says Ninel, “and maintenance isn’t an issue. It gives off an even, radiant heat and looks great in our home.” Joe agrees and adds, “Our utility bills are way down, too, and we’re happy about significantly reducing our CO₂ emissions.”

Go Green for a Brighter Future
The overdeveloped western world has no right to consume more resources and produce more pollution than the rest of the world. We can all pass on a secure, abundant and richer future to our children and grandchildren, if our modern lifestyle was less overindulgent.

Discriminating Domestic Devices
A loud clunk and it's gone: the washing machine that you've relied on almost daily for the last 15 years has rinsed and spun its final load. Not worth the money to repair, a new machine is in order and you might as well get a new dryer while you're at it.

Renovate Responsibly
The bitter cold storms last winter convinced us to add extra insulation when we renovate our draughty house this spring. We need to make sure the insulation is adequate to protect us from cold weather. We're also looking for the least toxic and ecologically safe products we can find.

Green Your Bathroom
You may be making ecologically sound changes in the kitchen, living room, and bedroom but what about the bathroom? You can change your bathroom into a beautiful green oasis and help save the earth all in one fell swoop.

No Bed of Roses
The good-night wish, "Sleep tight, don't let the bedbugs bite may have lost its charm with the recent spate of bedbug outbreaks. Across Canada reported cases of bedbug infestations have increased as much as 600 percent in the past decade.

Elder Care in Canada
The lobby at the New Vista Care Home in Burnaby, British Columbia, is alive with chatter and laughter. A comfortable lounge area invites visitors to sit, but I wait my turn by checking out the sign that spells out the home's mission.

Home Green Home
Water swirls down the drain from the tap left on while you brush your teeth. In summer, your air conditioning bills climb faster than the temperature rises. In winter, a draft of cold air leaks under your front door. You want to make changes, but where do you start?

Green Holiday Entertaining
Now that green is all the rage, eco-friendly events are popping up everywhere, especially during the holiday season. Planning your own environmentally conscious event is not only manageable, but it's also fashionable.
