Agenda • Evolution of Radiant Heating & Cooling Systems through the ages • Emergence of Radiant Panels • Recent Innovations & Looking Forward Popular Mechanics Issue: Sep, 1949 Chinese Kang & Dikang • The Chinese kang (bed-stove) is said to be derived from the concept of a heated bed floor called a huoqiang found in China in the Neolithic period, according to analysis of archeological excavations of building remains in Banpo Xi'an. However, archeleogical sites in Shenyang, Liaoning, show humans using the heated bed floor as early as 7,200 years ago. • Typically, a kang occupies one-third to one half the area the room, and is used for sleeping at night and for other activities during the day. A kang which covers the entire floor is called a dikang (literally "ground kang"). Chinese Kang & Dikang • "The interior of an inn". In illustration in H.E.M. James book.

Korean Ondol • An ondol, also called gudeul, in Korean traditional architecture, is underfloor heating which uses direct heat transfer from wood smoke to the underside of a thick masonry floor. The earliest use of ondol has been found at an archaeological site in present-day North Korea.

It’s main distinction is the ability to store a large amount of heat. This means that you can rapidly burn a large charge of wood without Aoverheating your house. The heat is stored in the masonry thermal mass, and then slowly radiates into your house for the next 18 to 24 hours. You get a number of benefits, described in more detail below. If you burn wood fairly rapidly, it is a clean fuel. If you try to burn it too slowly, the fire will change from flaming to smoldering combustion.

    Chapter 4: Operation and Maintenance This chapter is formatted as a stand­alone manual for owners of rocket mass heaters. The procedures outlined in this chapter apply to heaters built according to the preceding chapters of the Rocket Mass Heater Builder's Guide (Wisner, 2014), or proven to work in a similar way through extensive prototyping. Heaters with improvised alterations or "improvements," including unconventional chimneys, may present quirky behaviors not covered here. For general troubleshooting tips for non­standard heaters, we recommend the FAQ section of the general text Rocket Mass Heaters by Evans and Jackson.

  • Could a Masonry Heater Be the Main Heat Source in a Tight House?
    Jonas Kasiliauskas T6616KA COULD A MASONRY HEATER BE THE MAIN HEAT SOURCE IN A TIGHT HOUSE? Bachelor’s Thesis Double Degree Program in Building Services Engineering January 2017 DESCRIPTION Date of the bachelor's thesis Author(s) Degree programme and option JONAS KASILIAUSKAS DOUBLE DEGREE PROGRAMME IN BUILDING SERVICES ENGINEERING Name of the bachelor's thesis COULD A MASONRY HEATER BE THE MAIN HEAT SOURCE IN A TIGHT HOUSE? Abstract Masonry heaters are the oldest heating method for one family houses. Earlier houses had high leakage air- flow rates because thermal efficient insulation material was combustible by that time /20/. The masonry heater perfectly fits for air leaky houses. Nowadays, houses are more insulated and have an air tight enve- lope. People don’t want to spend time for supervising heating systems, that’s the reason they choose a heat- ing system with automatism. The main aim of my thesis is to evaluate if it’s possible to use masonry heating in tight envelope houses. With help of the literature sources I consulted and the interview with a professional masonry heater builder I will try to give an answer to that question. The secondary aim is to select a ventilation system to one family house, which has a masonry heater. The example house I will use in this thesis will be a one family house, with a floor area of 95.4 m2 located in Vilnius, Lithuania. I chose this house and location because of the popularity to use gas in this country. I’m going to evaluate installation and ten-year exploitation costs to have more reasonable results.

The “rocket” in the name comes from a line of clean-burning cook stoves developed in the 1970s, using an insulated heat riser, to produce a very clean and efficient fire. “Mass” refers to the mass of masonry where it stores its heat. An RMH heater always in- cludes an insulated, vertical, chimney-like heat riser as part of its clean-burning com- bustion chamber and a thermal mass to extract heat from its clean exhaust. An RMH can warm a home using a fraction of the firewood required by other common heaters, such as woodstoves and boilers.

The Korean Onggi Potter. Smithsonian Folklife Studies, num­ ber 5, 292 pages, frontispiece plus 117 figures, 1987.—Korea's onggi potters, producers of a class of domestic food jars used to prepare and store soy sauce, kimch'i, and other diet staples, work even yet in circumstances reminiscent of those prevailing during the Yi dynasty (1392-1910). Not only their repertoire of tools and techniques but the very conditions by which they live and organize themselves into work groups mirror those described in nineteenth century accounts. In this study, we consider the history of the onggi industry, exploring a link between the artisans and a community of religious dissenters driven into hiding nearly 200 years ago. We also discuss the extant ware forms and their practical uses and report on the state of the contemporary industry as indicated in field survey data collected at 11 workshops in six South Korean provinces. A bibliography of Korean, Japanese, and Western language sources on onggi accompanies the text.
