Patio heaters are heaters for use in open spaces. They are popular for domestic use and outside dining areas particularly in open cafes and restaurants with outdoor seating.
For home-brewers, the possibility of residual ingredients or by-products in the brewed biodiesel is a compelling reason to "wash" then test the biodiesel. Biodiesel that is commercially sold, is regulated and made to the ASTM standard, does not allow for residuals to be present. Therefore, you should have little worry with commercial biodiesel .8. What is biodiesel made from, besides vegetable oil?Patio heaters run on a variety of fuel like natural gas, propane, butane, kerosene etc. Some electric models are also available. The natural gas models are popular because they use the same fuel system as an outside grill. Portable patio heaters have a portable cylinder attached to the heating unit.The potential for carbon monoxide poisoning is a deadly hazard that can impact anyone. Your best defense is an understanding of the risks and how to minimize them.What to Look For?It's kind of interesting to watch, truthfully. As the biodiesel industry gets older and wiser, more and more OEMs (Original engine Manufactures) are warming up to this idea and making positive statement about 100% biodiesel and this is reflected in their warranties. The truth is, it's kind of tough for them to argue the fact. The diesel engine, after all, was designed for this. Caterpillar, John Deere, and New Holland all accept and explicitly warrant B100 biodiesel in their engines. Others are taking a more "wait and see" attitude. They are warranting blends like B20, or B5 but stop short of wholeheartedly endorsing the idea. Other say they "neither oppose nor endorse" the use of bio-fuels.This is where it gets interesting; Mercedes and Volkswagen both sell cars in Europe and the USA with diesel engines and there is no problem with warranty issues in Europe, but here in the good ol USA, they don't/won't support the use of biodiesel or the biodiesel industry. So bottom line? One, check your warranty. Two, if a OEM wants to deny a warranty based on biodiesel use, they can. But legally, they have to show a compelling reason that biodiesel hurt the engine. Which would be very hard to do. This is a very good reason to use ASTM (Commercial biodiesel) fuels, especially in newer cars or trucks.
Patio heaters are available in shops where natural gas or butane is available. Some specialty shops for home decorating also keep patio heaters. Patio heaters are not to be treated as toys and it is prudent to not let children operate them.
