Wood Combustion – How Firewood Burns & How to get the best heat while being eco-friendly

...combustion takes place. This is the heat-producing stage. It occurs at two different temperature levels: primary and secondary combustion. Primary Combustion: The process by which gases are released from wood and burned is called primary combustion. Primary combustion begins at about 540° F, continues toward 900° F...

Heating with natural gas

...combustion is condensed and recovers the latent heat of condensation. This is a very efficient combustion system, somewhere in the area of 90% to 97%. There is also very little loss during the transmission of heat energy. With a conventional boiler: This is a clean burn and it emits very few particles. However, overa...

...combustion appliances, venting requirements and ventilation systems. 2.1 Basic combustion venting measures: Meet all of the following requirements: Ensure there are no unvented combustion appliances. Install carbon monoxide detectors on each floor. Ensure all fireplaces, wood stoves and pellet stoves are ei...

The importance of Cleaning HRV intakes

How to keep your HRV clean and operating efficiently

...Combustion , we have been monitoring the levels (which are now about 80% lower) and will continue to adjust the flow-rates as well as intake and exhaust locations for optimum radon removal. We will document that process fully in the near future, but that’s not what I’m currently here to tell you. I was surprised when...

Gas powered tankless water heaters

Are tankless water heaters good?

...combustion. These models are not recommended because they draw in and evacuate heat from the home and because a defect in the seal of the combustion chamber could – in the event of flow reversal or depressurisation – lead to a risk of carbon monoxide poisoning. Higher-end models of gas-fired instantaneous water hea...

...combustion engine vehicles. The economic case for the Tesla roof follows that same principle. The Tesla solar roof tiles integrate with identical non-solar ones for a seamless look we like When can I get a Tesla solar roof? The answer to that is, don’t hold your breath. That’s a supply and demand issue, and i...

...combustion fumes at the industrial production site, which is then re-injected into the mix. That CO² is sequestered permanently in the material instead of being released into the atmosphere. The cement reacts with carbon dioxide to form calcium carbonate (CaCo³) and calcium silicate (CaSiO³) which acts to harden the ...

High efficiency fireplaces and how to choose one

Choosing the right wood-burning stove or fireplace for both heat output & the environment

...combustion process of wood and they start to burn off at about 540°F. That's where the term 'secondary combustion' comes in with stoves that have that capacity, which by now is offered by almost all manufacturers. Without the secondary combustion feature, much of the fuel value of your wood (up to 60%) is lost up the c...

Choosing the right firewood

Burning the right firewood for maximum heat output and minimum environmental impact

...combustion. Buying the right stove in the first place allows us to run them at the optimum efficiency level while giving the level of heat required to heat the home - it's a balancing act, too big and either it overheats or doesn't get to correct temperature and burns inefficiently, too small and we jam them too full t...
