Rocket Heaters earliest known relative, the Rocket Stove, was originally conceived in 1982 by Dr. Larry Winiarsky for the Aprovecho Research Center. Ianto Evans of the Cobb Cottage Co. then proceeded to apply Dr. Winiarsky's principles on cook stoves to household heating using Cobb as a thermal mass, in effect creating a unique masonry heater. Ernie and Erica Wisner then picked up on this technology and further developed it into a full fledged masonry heater.


Since that time Rocket Heaters, and their masonry counterparts, Rocket Mass Heaters, have taken off with the general public and have seen almost viral like attention throughout the internet, particularly on permaculture, ecology, nature, botany, self sufficient living, homestead, and off grid living forums and their respective communities and sub cultures.


Rocket Heaters have grown and continue to evolve out of a necessity to use wood cleanly and sustainably as a cost effective and environmentally friendly alternative to conventional heating sources, and to rival gas and electric as the sustainable and economical heating source of the next century.

A typical Rocket Mass Heater made with cob  and other natural materials coupled with a 55 gallon drum for the primary heat exchanger. Please note that masonry heaters and heaters with thermal mass are not UL listed and must be built on site. So unless you are a professional or know what you are doing, and your home's foundation can support over 1200 pounds of weight, and assuming your insurance will cover such a heater and your building codes will allow it, then chances are this type of masonry heater is probably not going to be viable for you.

A Yahoo! News Article about high heating costs.


The polar vortex caused nationwide shivers when it swept across the United States in early January. Now it’s causing convulsions and hyperventilating as millions of American open their latest heating bill.

Emma Turpin of Richmond, Kentucky, got a $140 electric bill in December, which is typical. But the bill for January spiked to $429, which is almost equal to the $450 in monthly rent she and her husband pay for a one-level, two-bedroom house. “We’re still trying to figure out how we’re going to pay it,” she says. With a two-month-old baby at home, she’s reluctant to turn the heat down by much, as a lot of people do to cut heating bills. To shave costs, the family is eating in more and curtailing trips to Walmart, which saves on gas and provisions both. Turpin also hopes to sell a few of her fancier handbags and other items on eBay, but interest is tepid.

“It seems like everybody’s in a rut right now,” she says. As a last resort, she and her husband may see if local churches or the Salvation Army can offer any kind of heating assistance.
