Greenhouse Heating 



is a perplexintr Question to all florists 

 except those using 



Morehead Steam Traps 



HAVE you ever talked w^ltb a brother florist \rlxo uses Moretaead Return 

 Steam Traps ? If not, do so at first opportunity and be oonvinoed tbat 

 you must Install one at once. 



There are more MORBHEAJ) TRAPS installed in greenhouses than o^ all other 

 makes of steam traps combined. The Morehectd is distinctly a florist's trap. Every 

 feature of its construction has been treated with a yiew of meeting the special needs

Greenhouse Heating. 



THE FUEL MARKET. 



Belated buying, shortage of cars and 

 labor trouble are strengthening prices 

 on coal. Anthracite demand is now 

 normal for this season of the year. The 

 colder weather of the last week forced 

 the starting of fires in apartment 

 houses. Also, West Virginia railroads 

 proved to have a less abundant car sup- 

 ply. The two- thfhgs brought a stronger 

 tone to an easing smokeless coal mar- 

 ket, with the result that mine run is 

 now selling at $1.40 to $1.50 at the 

 mines, with the emphasis upon the 

 latter figure. 



PIPING AN INDIANA HOUSE. 

 I am building one greenhouse, 20x115 

 feet, running north and south. The 

 gutters are seven feet high and the 

 ridge twelve feet from the ground. 

 Both ends are glass, and there are four 

 feet of glass in the sides, the remain- 

 ing three feet being boarded up. 1 

 want to heat this house with hot water 

 and am thinking about purchasing a 

 sfeven-section Ideal boiler. I should 

 like to know how to pipe this house 

 so that I can keep up a temperature 

 of 60 degrees in cold weather; the cold- 

 est we have here is about 5 degrees 

 below zero. I shall put my boiler in 

 the cellar and will be able to give the 

 pipes any kind of fall. Do you think 

 it necessary to have a generator? This 

 boiler is to have 2,225 feet of radiation. 

 Will it carry another house of the same

size and also a small store room, 15x20 

 feet? W.F.E. 



About 1,200 square feet of radiation 

 will be needed to heat the house de- 

 scribed to 60 degrees, so that a boiler 

 with a rating of 2,225 square feet 

 would have to be crowded pretty hard 

 to heat two houses of this size to 60 

 degrees. If 52 degrees would be enough 

 for one of the houses, for which 1,000 

 square feet of radiation would answer, 

 the boiler could be used for the two 

 houses with a good degree of economy. 



For piping, run one 2i.^-in(h flow 

 under each ridge and one upon each 

 eave plate. Connect each of tbo side 

 flow pipes with a coil of four 2-inch 

 return pipes and the other flow pipe 

 with five returns under the benclies. It 

 will be well to have the highest point 

 in the flow pipes as nearly over the 

 boiler as possible and connect each

with the pipe leading to the expansion 

 tank. 



Run each of the pipes with a fall of 

 one inch in fifteen or twenty feet. The 

 circulation is in no way benefited by 

 running the pipes with a considerable, 

 pitch. On the other hand, the pipes 

 should be kept as high as possible 

 above the heater, and hence the less 

 fall given the pipes the better; all 

 that is required is enough to keep the 

 air from pocketing. While a slight 

 reduction in the amount of piping
