nine Reasons Companies Never Use Sensors in Wood Stoves

Posted by Earth Stove on March 2, 2013 with No Commentsas , , , , , ,

Temperature and oxygen sensors make autos, furnaces, boilers and scores of other goods work as cleanly and efficiently as feasible by regulating combustion, reducing particulate emissions and maximizing performance. So, why has not any North American manufacturer integrated them into wood stoves nevertheless? 1 inventor questioned many folks in the stove business and came up with this record of the nine most frequent reasons sensors are not utilized:
    one. They have put controls on “wood” stoves.&nbsp&nbsp

    They are referred to as pellet stoves.&nbsp

    two. They will not need to have to.&nbsp
    The marketplace is not demanding it, mostly because men and women will not know the technologies is accessible.

    3. It’s a new engineering.&nbsp
    Wooden stove makers are dreadfully sluggish with adopting new technologies.

    four. They never use wood stoves on their own.&nbsp
    The large greater part of higher management in stove businesses do not heat with wood, so they will not recognize the advantage of automation.

    5. They’re not becoming pressured to.&nbsp
    Why add complexity to a item that sells well and needs tiny assist?

    six. It’s way too pricey.

    Any new technological innovation commences out in lower volumes and is costly. Stove organizations are really price conscious.&nbsp

    seven. They can do the very same issue with a bi-metallic spring.&nbsp
    Bi-metallic springs do give some measure of management.

    8. It may possibly call for electrical energy. &nbsp
    There is a perception in the industry that individuals who warmth with wooden will not want to plug in their stove.

    9. They have other initiatives to work on, like pellet &amp gasoline stoves.&nbsp
    The gas stoves are by significantly the goods that ship in the maximum quantity, and pellet stoves are increasing in quantity. Wood stove shipments are flat, so they commit their sources on these other places. Some companies go a long time with out making any significant modifications to their wood stove line.

    These nine reasons are reproduced with permission from Right here are 3 much more of our own, for excellent measure:

    ten. No incentives from the government.
    Unlike in Europe, in The us there are no incentives for cleaner and a lot more successful wood stoves. There is no Energy Star rating or green label equivalent to reward buyers for buying, and manufacturers for creating, the cleanest and most efficient products.

    eleven. Not sufficient effectiveness information.

    There is small information about actual efficiencies in the discipline over the system of a day of heating. Could 70% in the lab be fifty five% if averaged more than the program of a fireplace?

    12. Fuel is still comparatively cheap.&nbsp
    Fossil fuels are even now relatively cheap and plentiful in the United States, and so is firewood.

    What do you consider of the checklist? Are we forgetting any causes why U.S. producers aren’t incorporating sensor technologies in wooden stoves? Depart your ideas in the comments section below. You can also verify out our previous coverage of wood stoves and oxygen sensors below.

      Beware of Ads for ninety nine% Successful Wood Boilers

      Posted by Earth Stove on February 19, 2013 with No Commentsas , , , , ,

      Alliance for Environmentally friendly Warmth, January 7, 2013 – Each situation of Mother Earth News, a journal that caters to the granola, Birkenstock and organic vegetable group, also carries numerous adverts from outside and indoor biomass boiler firms. The Alliance for Eco-friendly Heat has regularly place the spotlight on outlandish promises by numerous manufacturers. This month we characteristic Kuuma who is advertising “ninety nine.4% comb. effectiveness” wood burning furnace “analyzed by EPA Licensed Lab-Intertek Tests.” The December/January problem of the magazine also has an half-website page ad from Central Boiler stating that their E-Basic “calls for up to 70% much less wood than other wood-burning appliances.”

      Exaggerated efficiency promises have turn into virtually commonplace in the boiler and stove sector, taking advantage of shoppers who don’t know that there is no typically approved way to publicize performance any far more. 1 rule of thumb: Beware of any equipment declaring 99% efficiency. Any assert of effectiveness in the higher 90s is most likely combustion effectiveness, not thermal effectiveness – the quantity of valuable heat developed by the device. &nbspCombustion efficiency has no bearing on the beneficial heat a unit generates which is why almost all stoves, boilers and furnaces companies advertise thermal efficiency. &nbspThe most productive wood stove, employing EPA approved efficiency regular is 82%, and the most efficient boilers making use of that same common are probably below 90%.

      We at the Alliance for Green Warmth applaud Mom Earth News for constantly great editorial protection of wood heating, partly thanks to their contributing editor John Gulland, and we comprehend that they aren’t responsible for promises produced by advertisers. (We also enjoy granola, organic and natural greens, property-baked bread, and so forth. Birkenstock – not so much.)

      Update: See the comments area below for a reaction from a Kuuma consultant. &nbspKuuma has a bit transformed their advert to say “combustion” instead of “comb.” which buyers could believe indicates combined efficiency. &nbsp Kuuma is nevertheless 1 of the only boiler or furnace manufacturers who advertises their combustion effectiveness which many buyers confuse with thermal efficiency.
