This is what I get for spending my lunch hour on Ebay. I noticed an auction for a used Taylor Water Stove. The description was a lot of the usual hyperbole about how you can heat a Walmart with one of these, burn “all manner of combustibles,” heat your pool, yada, yada, ya. So I asked the seller (a Taylor dealer) what the “overall efficiency” is on these stoves. Answered within a couple of minutes. To wit: “I know there are a number of rating systems for the efficiency of a wood burning stove- but publishing a rating without pages of qualifications really isn’t fair to a regular person without ASHTO access and the ability to interpret the results. Taylors are rated between 87 and 93 percent efficient- based on a number of test conditions. That being sais- anyone can understand that the bigger the water capacity of the stove the more efficient it is in wood useage since it’s the water that stores the heat. Taylor and the various knock-offs have the largest water capacity in the industry. We heated a 2600 sf home in NH, had plenty of hot water and provided over 200 gallons of hot water to our horses in the NH winter, using a Taylor 260- so small it’s not made anymore- and 3 cords of mixed green unsplit hardwoods A YEAR.....It’s the water that does it......more water = less wood.” Amazing! Over 90 percent efficient and somehow you’re getting energy out of water! Sign me up! Too bad the model that only burns 3 cords of green, unsplit wood isn’t made anymore. Que lastima!
