The heating network uses wood pellets, a by-product from Quebec’s forest industry, as fuel. Wood is a local staple and independent of wide price fluctuations; it is harvested with minimal energy input and contributes to the regional economy. The combustion of premium wood pellets is a clean and environmentally friendly process and, as a carbon neutral source of energy, it does not contribute to the greenhouse electricity off peak hours effect.

At the heart of the system is a boiler plant housing four Viessmann Pyrotec KPT-1250 wood-fired boilers (each rated at 1,250 KW) in a 5 MW cascade system. The cascade arrangement provides maximum boiler plant efficiency with high turndown ratio (1:16) that precisely matches load. The Pyrotec hot water boilers have met their published electricity dance moms song performance ratings for combustion efficiency (up to 85 per cent) since the biomass heating system went online in October 2011. A 5.2 MW natural gas boiler provides emergency backup for the biomass boilers, and a 650 KW diesel generator will ensure continuous operation of the entire district heating system in the event of an electric power failure.

The boilers heat two 22,000 L buffer water tanks before heated water natural gas jokes (90°C supply/50°C return) is distributed through a highly efficient, low temperature hydronic heating network for district DHW and space heating. Pre-insulated underground piping in the 2.2 km system ranges from 8” in diameter exiting the boiler plant to smaller pipes feeding row houses (1” diameter) and other buildings throughout the site.

A $22.7-million investment by the Quebec Government, $4.7-million grant from Natural Resources Canada’s Clean Energy Fund and financial assistance from Hydro-Québec affirm the vision and forward thinking of the Quebec community regarding sustainable development. By integrating aspects of sustainability and green technologies, La Cité Verte has become a model for future developments in the province and the first green technology showcase in Eastern Canada.

I recently installed a new 35,000 BTU wood pellet gas and electric phone number stove on the main floor of my 1,800 square foot house. Although I have propane and electric backup, my pellet stove heats my entire house. The stove and chimney liner cost $4,734 including tax and I paid a WETT-certified technician $650 for installation; total cost, tax included was $5,384.

Operating and maintaining my pellet stove is easy. I buy pellets – about ten bags at a time, which is all gas outage that fits in my car – and store them in my garage. Due to the stove’s small hopper size, I fill it twice daily. It takes me about one minute each day to fetch the window electricity experiments spray and wipe the stove glass clean so we can enjoy the pellet flame. Once a week I need to spend about 10 minutes cleaning ash from the inside of the stove and emptying the ash pan.

Other than the cozy heat, the next most attractive feature of my pellet stove is the low operating cost. In Revelstoke, pellets cost $5.24 per bag or $262 per tonne. This works out to $15.41/ gigajoule (GJ). Add $0.50 /GJ to operate the stove’s auger and fan for a total pellet cost of $15.92/GJ. This compares with $24.36/GJ for propane (including delivery, carbon wd gaster cosplay tutorial tax and electrical fan); $29.47/GJ for electricity; and a whopping $33.93/GJ for heating oil.

Revelstoke has a cool winter climate; from November to February the average daily temperature is about -5°C. From my old propane bills, I know that my home uses about 0.7 GJ/day of heat energy (including heating appliance efficiency losses) during the coldest part of the winter. Annually my house requires 81 GJ of heat energy – equivalent to 4.8 tonnes of wood pellets. So now, on the coldest winter days, I spend $11.14/ day for wood pellets. If I used propane, it would cost $17.05/day; electricity (adjusted for greater energy efficiency) would cost mp electricity bill payment jabalpur $17.94/day; and heating oil would cost $23.75/day. On an annual basis, pellets will cost $1,290; propane would cost, $1,973; electricity, $2,076; and heating oil, $2,748.

The only drawback of installing a pellet stove is the relatively high upfront cost. My stove, including installation, cost $5,384. The City of Revelstoke administers the provincially-funded Woodstove Change-out Program that pays a rebate of $500 to homeowners who replace old inefficient wood stoves with new EPA/CSA certified high-efficiency pellet, wood or gas stoves. Unfortunately, since I changed a gas stove gas prices under a dollar for a pellet stove, I did not qualify for this rebate.

I am happy with my pellet stove. I like the ambience and cozy heat. It operates automatically and requires infrequent filling. Maintenance is very easy. And pellets are cheaper than such alternatives as propane, electricity and heating oil. I am grateful that I was able to afford the cost of purchasing gas pains 6 weeks pregnant and installing my stove. However, lower -income families may not have the same ability. Moreover, they may not be willing to accept a 7.9 year payback period. Nevertheless, wood pellets provide the best heat and are the lowest cost energy source in my hometown, Revelstoke, and in many other Canadian communities.
