A FlueCube chimney cowl is designed to not only improve the air of our communities, whatever the landscape they’re in, but to also protect self sufficient, environmentally sustainable, efficient and affordable off-grid home heating.
It’s aim is to correct ventilation problems that occur above all vertically vented solid and liquid fuelled appliances that require consistent combustion conditions in the worst weather conditions, including emissions trapping inversions.
Strict national/ local government standards placed on appliances, council zoning and the policy rhetoric directed around domestic wood heating toward the method’s phase out is not adding benefits to consumers nor is it expressing a lot of truth in the justifications it provides to penalise consumer’s affordable heating choices.
Very good wood stove designs came out of the 1970s oil crisis and many wood stoves replaced oil fuelled heaters and boilers. Then came catalytic combustors to stoves and a sure thing lab calibration written in to a knock out national standard. The testing standard would have us assume that the appliance design is what is causing emissions. Catalysts would be inserted as some magic filter which would need replacing due to clogging and were also expensive (see hyplinks here, and here). Understandably the majority of manufacturers who didn’t use them in their designs also complained. So then non-cats were developed to pass the same/ similar test. What about the flue and the winter weather above it – i.e. what about ventilation, and its effect on emissions, soot, creosote, poor/ varying combustion conditions – negative atmospheric pressure?
The exhaust system and atmosphere above it has been largely ignored as having a major influence on smoky fires. Off-balance – top down funded scientific research and resulting curriculum presents a technology standard that is clean in name, mostly due to optimum performance conditions being artificially manufactured, calibrated inside a laboratory through a 100,000 US dollar apparatus. In the field, in typical winter conditions these ratings are lost from external atmospheric pressure factors, and many cases the newer certified technology can fail to prove any benefit to the consumer without additional technology that focusses on the exhaust vent.
Town councils enforcing change-outs preach healthier air and reduced PM10/ 2.5 emissions due to the now growing number of new trigger happy heat pump owners who gracefully increase the electricity demand. Heating oil tankers and trucks filled with gas bottles drive around our suburbs. Electricity, gas and oil prices fluctuate along with the demand, green-washed energy market risks, and over-inflated, statistically exaggerated economic projections.
We hear from many who had changed their wood heaters that now get smoke in their rooms worse than they had before, as well as it still belching out their chimneys – some models with the help from electric fans. In, power cuts, earthquakes, snow storms what is good for the consumer? Electricty, gas, propane, heating oil, electric fans, electronic sensors and ignitions, a reliance on pellet shaped fuel?
The dillution tunnel apparatus used in Australia and New Zealand standards is used to certify wood burners yet the data collected is only taken from the appliance separated from flue system and without the winter atmosphere. As an emissions health and safety evaluation, does it measure emissions at the front where people sit? It is observable that cold inversion layers that trap smoke into our breathable air are a significant cause in producing the smoke in the first place. Whatever processes that may improve combustion in the appliance, they are only still hindered when cold air clogs up the exhaust system and/ or the catalytic combustor.
Although I feel firebox standards have in general been falsely represented in the way of emissions reduction, the idea of standardising technology isn’t a bad thing. Inefficient open fires have been outlawed in many places and having the ability to cook our food and heat our water centrally at no additional cost to our gas, oil or electric bills in winter is fantastic, even healthy. Some older enclosed burners may have been inefficient and possibly more polluting, but not necessarily all of them before they received that ‘label’. We believe with the FlueCube installed and if appliances were judged in the field with the rest of their kit in place, they would have been given a fairer review and consumers would be better informed. Wood heating is rightly popular. People are not going to sit back and let less sustainable urban dwellers phase the method out of existence.
Our website at http://www.fluecube.com is intended to not only promote Neville D’Herville’s revolutionary FlueCube itself but to also provide access to information useful to wood heater owners or those considering a cheaper alternative to more expensive, less sustainable, less efficient, less aesthetic methods of home heating.
Each FlueCube agency/ national distributor and wholesaler is responsible to find local or national manufacturers. Each are encouraged to provide fair access to retailers, chimney cleaners, lists and ratings of certified/ well designed wood burners, and quality firewood merchants. We support local industry and ethical practices in those industries as they focus on improving the quality of our lives. We believe in supporting the local economy and a cleaner environment.
We do not support funded wood smoke/ wood heat activism that spreads alarmist social-marketing messages – vested interest propaganda that misleads consumers and appears to support only corporate backed fuel transitions. They often suggest natural gas or other influential – commercial alternatives. Well funded and publicised fear campaigns are not new and the lesser influential wood heating industry can struggle to compete with them without their consumers’ help. Public opinion is forever being manipulated. What were once trustworthy sources of accurate information are now skewed with special interest groups who do well in twisting scientific research to commercial and investment advantages.
We are sympathetic to those suffering allergies, caused irritation or more serious illnesses by irresponsible neighboring wood heater owners who produce high concentrations of smoke emissions. Councils should exercise useful practices in dealing with these nuisances. If there is such a great concern, license users/ provide a warrant of fitness as you would do with the expansive choice in road vehicles. Revert back to common sense fire safety and ventilation standards first and foremost. We need to consider the health impacts of not having access to affordable wood heat.
By owning international patents spreading over 40 countries we would like to see this cheap wood heating ventilation fix evolve to industrial chimney applications as well. Not only does our customer feedback comment on the huge improvements on enclosed wood heating efficiency and output but it is also showing a positive result on coal burning heaters, natural gas and some open fireplaces as well.
Neville D’Herville’s invention is exciting, has point of difference and we are grateful to the continuing support and interest we are receiving worldwide as it is discovered. We are only small and appreciate the research that has gone into pollution chemical research and recording. We are aware that there are accepted/ instituted approaches in reducing pollution and our invention as part of an ancient industry is comparatively new on the scene. To express its effectiveness in the form of data we require the right equipment available, common sense methods, and trustworthy, experienced physicists and technicians. If the same dilution tunnel testing could be achieved in a typical upright flue and without the help of extraction fans to exhaust the gases, and with the top of the flue inside the atmosphere for which it is intended, then true clean air ratings on wood burners can be achieved. Until then we are making it lawfully available because it works extremely well and the public benefit from it.
No law dictates which cowl to use as there are too many atmospheric variants. That in itself suggests that the atmosphere above wood burners is significant to their emissions, efficiency and controllability. It is also obvious that by zoning airsheds, allowing wood burners in some and not others also suggests atmospheric and geological relevance to the clean air cause. European standards, industry experts and chimney cleaners’ endorse the use of the FlueCube, and from these real experts it comes highly recommended.
Your help buying and installing a FlueCube on your chimney – designed to improve your lives during the winter cold, will help us continue and improve the lives of many. So thank you. Happy heating.
