Wood Burning Ottawa How To Significantly Reduce Energy Bills

Wood Burning Ottawa

How To Significantly Reduce Energy Bills

The effectiveness of wood burning Ottawa homeowners expect is impacted by a host of factors. The quality of the fireplace or stove and the quality of fuel are both important to consider when working to reduce your energy expenditures during the arduous winter months.

Reduce Costs Long Term By Investing In Quality

Installing any new heating system incurs a significant initial cost. Traditional fossil fuel heating systems (natural gas, electric, propane, or heating oil) can cost anywhere from $2,500 to $7,500, while wood stoves or pellet stoves start around $1,000 and extend to $6,000 (some systems go beyond).

Is A More Expensive Stove Always Better Quality?

Talking about a quality stove quality is talking about two things:

1. Heat transfer
2. Combustion

Certification bodies like the Canadian Standards Association(CSA) look at these factors and certify stoves based on stringent criteria. Generally, heat transfer and combustion on CSA or United States Environmental Protection Agency (EPA) certified stoves are uniformly high.

Ultimately, the quality of wood stoves sold by reputable dealers is very high, and the choice consumers must make is for a unit that is aesthetically pleasing and suitable for household size and needs.

Look For Quality Local Fuel

Firewood with high British Thermal Unit (BTU) content is best for a wood-burning stove. High BTU content means fuel will burn for a long period. The highest BTU-rated woods that are available in Ottawa are:

–          Oak

–          Maple

–          Birch

While the lowest btu rated are:

–          White cedar

–          Poplar

–          White Pine

–          Fir

–          Spruce

–          Balsam

Even the lowest-rated woods contain BTU and will burn well if they are dry. The only kind of wood that you will want to always avoid is wet wood- regardless of the type.

Opting for a local fuel makes the most sense in many ways. Fuel will be significantly less expensive. In addition, choosing local also means that you won’t be at risk of bringing an insect infestation back with your out-of-territory firewood- as in the case with the Emerald Ash Borer.

Get The Most From Your Firewood

Freshly harvested wood (or green wood) contains a lot of moisture. Wood recently cut from a living tree, or that has been left out in the elements, can produce one-quarter of the BTUs as “seasoned” or sufficiently dry wood, or less.

How to Season Firewood

If you’re using wood that you’ve harvested, season it by splitting, stacking on a slightly elevated surface (such as a skid) with enough space for airflow throughout, and leaving it to dry for at least 1 full year.

The beginning of summer is the most ideal time to split and stack your wood- with the hottest air and a large amount of wind. It will dehydrate the fastest at this time. It should be left uncovered as long as possible; when the rainy season arrives, cover only the top and leave the sides open.

The true test for determining if your firewood has been dried sufficiently is to use a moisture meter- available at all fireplace supply stores. If you measure anything less than 15%, this is ideal.

If you can’t get a moisture meter, listen carefully to your stove or fireplace while you’re burning. If you hear sizzling- that’s a sign that it’s too wet.

Calculate Your Energy Savings

Natural Resources Canada released a substantial guide to residential wood heating in 2002, which includes a valuable formula homeowners can use to calculate potential wood heating savings.

The numbers used in this guide are reflective of prices from a decade ago, so we have updated the equation below to more accurately reflect the costs of today.

An example:

The Laurin family lives in an old, detached, relatively open-plan house in Ottawa. They heat their house with electric baseboards at 15 cents per kilowatt hour (kWh) on average. What would it cost them to heat with a high-efficiency advanced combustion wood stove with an efficiency of 70%?

The cost of a full cord of hardwood is $300. From Table 3, their annual heating load is 120 gj. Taken from Table 1, the energy content of electricity is 3.6 MJ/kWh, and the energy content of hardwood is 30,600 MJ/cord. The seasonal efficiency of electricity is equal to 100% and the seasonal efficiency of wood sits at about 70 %.

The annual cost of electric heating would be (0.15 ÷ 3.6) x (120 ÷ 100) x 100,000 = $5000.

The annual cost of wood heating would be (300 ÷ 30 600) x (120 ÷ 70) x 100,000 = $1666.67

In this example, if the high-efficiency wood stove displaced all of the electricity previously used for heating, the Laurins would save $3333 every year.
