Wood and pellet heating – Biomass heating in Québec

Wood and pellet heating - Biomass heating.

Biomass heating has been a reliable option for heating for many over a long period of time.
Ressource rarefication and exponential growth of fossil fuel cost brings new life to this heating method.
The combustible being from a renewable and local source This heating method can represent a promising alternative to fossil fuels. Log wood, wood pellets, are all readily available in Québec.
The development of this market segment along with the reinforcement of strict environmental policies have also contributed to perfect the available technology and considerably increase the boiler's efficiencies.

Operation of the heating system:

Put simply, these types of boiler use wood combustion to heat water that will then be distributed according to different heat load: radianting floors, domestic hot water, pool, spa, etc.
Depending on models, these boilers can be installed outside, in the mechanical room, use log wood, wood pellets, wood chips etc. Some of our models can even combine all these options in one single machine.

There is actually two main type of wood and pellet boilers:

Outdoor boilers:

Installed outside, either in a shed or over a concrete pad, they allow operation of the boiler from outside the building with wood, pellets or wood chips. Once the boiler gets it's stored water to desired temperature, it can then be directed inside through underground insulated piping.
This approach allows to keep all of the boiler's operation and materials outside of the main building.

Indoor boilers:

Installed in the mechanical room, these boilers allow to burn wood and pellets from within the building.
With a very high efficiency in the combustion process and respecting the latest EPA (environmental protection agency) standards, our line of boilers represent today the futur of biomass heating.

Advantages:

Wood and pellet boilers can take advantage of a renewable ressource often available in large quantity in rural areas.
This heating method therefore allows for important savings on heating costs over traditionnal fossil fuels
It also provides a very interesting capacity to combine other renewable heating sources such as solar heating systems. Finally, new technologies allow for automatic operation and feeding of the boilers, which eliminate a previously negative aspect of this heating method.
The different models being EPA certified also allows for home owners in urban areas to consider this heating source.

Biomass heating system components:

Boilers: outdoor or indoor, this is the heat source for the system. The combusstion is generally done in the secondary combustion chamber and is called gazeification combustion. In this type of boilers, the wood gasification technology provides combustion at very high temperatures and provides much better efficiency and fewer emissions compared to traditionnal wood boilers.

Underground piping

For outdoor systems, a double, insulated pex piping line has to be used to bring the heated water to the storage and distribution system located inside the building. The choice of quality insulated piping is very important to limit the tremendous amount of heat loss that can happen in frozen ground between the outdoor boiler and the building during winter months, therefore greatly reducing the system efficiency.

Storage or Buffer tank

Once heated, the glycol-water must then be stored ina tank before being distributed. The buffer tank is therfore a very important part of the system as it allows a buffer zone between the the heat production, that generally happens duringthe day and the heat distribution, that generally happens later in the evening and at night during the winter. The buffer tanks also allows for autonomy between burns and streamline large temperature differences between loads.

Finally the buffer will also allow for the integration of different input and outputs to the system: electrical boilers and solar heating systems can be added to add heat to the system and domestic hot water and pool/ spas can be heated from the buffer tank as well…

Heat Distribution

From the storage tank, we head towards the more traditionnal distribution system. This could be a radiant floor heating system, domestic hot water heating, spas, hot tub and pool heating etc.

Life span:

Most of our boilers are garanteed for a period of 10 years under manufacturer's warranty.
It's life expectancy will depend on many factors such as: wood / pellet type used and it's humidity content, maintenance schedule, water / glycol used etc.
A properly managed maintenance and upkeep will certainly provide a life expectancy around 20 years.

Average Cost:

Many models being available according to particular needs, we suggest you visit on site or at our on-line store at www.energierenouvelable.ca for more updated information on products and prices.

Maintenance:

A regular maintenance will greatly prolong the life expectancy of these boilers. We suggest to plan a scheduled maintenance of your system according to the manufacturer's recommandation to insure proper coverage of your system.
Please note that most of the maintenance can also be handled by the owner or we can offer a maintenance program.

Sizing:

Biomass boilers and heating system sizing is for the most part done the same way that of a traditionnal system. The chosen model will be a calculation between the heat loss of the space to be heated and the efficiency and rated power of the chosen boiler.
