Greenhouse Heating. 



IN EASTERN MASSACHUSETTS. 



Will you please tell me how many- 

 lines of 2-inch pipe, for hot water, are 

 needed to heat a house 11x40 feet and 

 seven feet to the eaves, with forty-two 

 inches of glass, the rest of the walls 

 being wood? I want a temperature 

 of 60 degrees when the outside tem- 

 perature is 10 degrees below zero. The 

 house runs east and west and is between 

 two larger houses. There will be one 

 6-foot bench. E. G. W. 



For a house 11x40 feet, with forty- 

 two inches of glass in each side wall, 

 two 21/^-inch flow pipes and eight 2- 

 inch returns will be ample to secure a 

 temperature of 60 degrees, when the 

 mercury does not drop more than 10 

 degrees below zero. 



A RANGE IN SWEDEN. 



Kindly give me some information 

 in regard to the arrangement of my 

 heating system. I have about 30,000 

 square feet of glass, which I intend 

 to heat with hot water. The houses 

 are separate, each 220 feet long, and 

 run east and west. They vary in width 

 from twenty to thirty feet and the 

 required temperatures vary from 50 to 

 60 degrees. Through the middle of the 

 range, crosswise of the houses, extends 

 a passage, where I intend to put the 

 main and return pipes, with pipes run 

 ning east and west from these to a 

 distance of about 100 feet. The boiler- 

 room, with a pit six feet deep, is at the 

 north side of the houses and contains 

 space enough for three large boilers, in 

 battery, to heat all the houses. 



I should like to know which would 

 be the better way — to install one large 

 main, running all through the middle 

 passage and branching off into 2^4- 

 inch flows in each house, and also a 

 large return to take all the return 

 water from all the houses, or to use 

 a 3-inch flow and 3-inch return as 

 main pipes in each house. If the lat- 

 ter plan is followed, the greatest dis- 

 tance that the water will travel will 

 be about 250 feet. How large should 

 the foundation be for a square brick 

 chimney sixty feet high, in heavy clay- 

 ground? B. & C. 



It will probably be best to run one 

 flow pipe on each side of the passage- 

 way, making these pipes sufficiently 

 large to supply all of the houses, ex- 

 cept perhaps the first house on each 



Awarded the Certificate of Merit 



at the National Flower Show, Boston. Mass.; and also received the universal approval of all 

 the visitors who examined its merits, the expression of the majority being 



"THAT IS THE BOILER I HAVE BEEN LOOKING FOR" 



The points of merit that appealed to the judges and the critical visitors were that the fire- 

 box is entirely surrounded by water, there being no brick work to require constant repair ; 

 every part of the boiler is easily accessible for cleaning and oiling, which is the most impor- 

 tant feature to ba considered in purchasing a boiler that is idle during the summer months ; 

 all the castings, doors, grates, etc., are maae double extra heavy.
